                         ARIZONA PUBLIC SERVICE COMPANY

                     NOTES TO CONDENSED FINANCIAL STATEMENTS

1. In the opinion of the Company, the accompanying unaudited condensed financial
statements  contain all adjustments  (consisting of normal  recurring  accruals)
necessary to present fairly the financial position of the Company as of June 30,
1998,  the results of  operations  for the three  months,  six months and twelve
months ended June 30, 1998 and 1997, and the cash flows for the six months ended
June  30,  1998  and  1997.  It is  suggested  that  these  condensed  financial
statements  and notes to condensed  financial  statements be read in conjunction
with the financial  statements and notes to financial statements included in the
1997 10-K.  Certain  prior year  balances  have been  restated to conform to the
current year presentation.

2. The  Company's   operations  are  subject  to  seasonal  fluctuations,   with
variations in energy usage by customers occurring from season to season and from
month to month  within a  season,  primarily  as a result  of  changing  weather
conditions.  For this and other  reasons,  the results of operations for interim
periods are not  necessarily  indicative  of the results to be expected  for the
full year.

3. All the  outstanding  shares  of  common  stock of the  Company  are owned by
Pinnacle West.

4. See  "Liquidity  and Capital  Resources" in Part I, Item 2 of this report for
changes in capitalization for the six months ended June 30, 1998.

5. Regulatory Matters -- Electric Industry Restructuring

State

ACC Rules.  In December 1996, the ACC adopted rules that provide a framework for
the introduction of retail electric  competition in Arizona.  On August 5, 1998,
the ACC adopted amendments to the rules. The ACC rules, as amended,  include the
following major provisions:

     +    The rules apply to  virtually  all of the Arizona  electric  utilities
          regulated by the ACC, including the Company.

     +    The rules require each  affected  utility,  including the Company,  to
          make  available at least 20% of its 1995 system retail peak demand for
          competitive  generation  supply  to  all  customer  classes  beginning
          January 1, 1999, and 100% beginning January 1, 2001.

     +    All  affected  utility  customers  with  single  premise  loads of one
          megawatt or greater will be eligible for competitive electric services
          beginning  January  1,  1999,  until  the 20% level  described  in the
          preceding  paragraph  is met.  Until  the
<PAGE>
                                      -9-

          20% level is met, affected utility customers with single premise loads
          of  forty  kilowatts  or  greater  will be able  to  aggregate  into a
          combined   load  of  one  megawatt  or  greater  to  be  eligible  for
          competitive electric services beginning January 1, 1999.

     +    Prior to January 1, 2001,  residential  customers  will have access to
          competitive  services through a quarterly phase-in of one-half percent
          of residential customers per quarter beginning January 1, 1999.

     +    Electric service providers that obtain Certificates of Convenience and
          Necessity  (CC&Ns)  from the ACC will be allowed  to  supply,  market,
          and/or broker specified  electric  services at retail.  These services
          include electric  generation,  but exclude  electric  transmission and
          distribution.

     +    As required by the rules,  in February 1998 the Company filed with the
          ACC proposed tariffs for unbundled  service (electric service elements
          provided and priced separately).  The ACC has not issued a decision in
          this matter.

     +    The rules establish that the ACC shall allow a reasonable  opportunity
          for the recovery of unmitigated  stranded costs.  See "Stranded Costs"
          below.   Affected   utilities   are   expected  to  take   reasonable,
          cost-effective steps to mitigate stranded costs.

     +    Absent a waiver from the ACC,  each  affected  utility  must  separate
          itself from all  competitive  generation  assets and services prior to
          January  1, 2001.  The  separation  must be either to an  unaffiliated
          party or to a separate corporate affiliate or affiliates.

     +    Beginning  January 1, 1999,  each affected  utility will be prohibited
          from providing certain competitive electric services, except through a
          separate affiliate.

     +    The rules contain affiliate transaction rules generally prohibiting an
          affected utility and its competitive  electric affiliates from sharing
          personnel,  office space, equipment,  services, and systems, except to
          the extent appropriate to perform certain permissible shared corporate
          support  functions.  No later than  December 31, 1998,  each  affected
          utility must file a  compliance  plan with the ACC  demonstrating  its
          compliance with the affiliate transaction rules.

     +    By  September  15,  1998,  each  affected  utility  must file a report
          detailing  possible  mechanisms  to  provide  benefits,  such  as rate
          reductions of 3% to 5%, to all standard offer customers and a proposed
          plan for residential phase-in implementation.

The amended  rules,  a copy of which has been filed as an exhibit to this Report
on Form 10-Q,  became effective on an emergency basis upon their filing with the
Secretary of State on August 10, 1998;  however,  the ACC must complete a public
process to adopt
<PAGE>
                                      -10-

the rules on a permanent  basis  within 180 days.  The Company  anticipates  the
completion of this process by year-end 1998 or early 1999.

The Company believes that certain provisions of the ACC rules are deficient.  In
February  1997,  a lawsuit was filed by the Company to protect its legal  rights
regarding  those rules.  That lawsuit is pending but two related  cases filed by
other  utilities  have  been  partially  decided  in a manner  adverse  to those
utilities' positions.

Stranded Costs. In February 1998, the ACC completed a formal, generic hearing on
stranded cost  determination  and recovery.  On June 22, 1998, the ACC issued an
order in this matter. The order allows an affected utility, such as the Company,
to choose between two options for the recovery of its stranded costs.  Under the
first option,  an affected utility that chooses to divest its generating  assets
to an unaffiliated  party must file a divestiture plan for ACC approval no later
than October 1, 1998, and such divestiture must be completed by January 1, 2001,
after which the  affected  utility  would be permitted to collect 100 percent of
its  stranded  costs,  including  a return on the  unamortized  balance,  over a
ten-year  period.  Under  the  second  option  (referred  to by  the  ACC as the
"Transition  Revenues  Methodology"),  an  affected  utility  would be  provided
sufficient  revenues necessary to maintain  financial  integrity for a period of
ten years or the ACC would  "otherwise  provide an  allocation  of stranded cost
responsibilities  and risks between ratepayers and shareholders as is determined
to be in the public  interest." The order also states an intent that the various
recovery  options "will provide the affected  utilities  sufficient  revenues to
enable them to recover  appropriate  regulatory assets." The order requires each
affected  utility to file with the ACC, on or before August 21, 1998, its choice
of options for stranded cost recovery as well as an implementation plan relating
to its chosen option,  including its estimated stranded costs separated out into
regulatory assets and other generation related assets.  Stranded costs estimates
vary depending on various assumptions,  estimates, methodologies and measurement
periods. Based on various assumptions,  estimates and methodologies, the Company
has  previously   estimated  that  its  recoverable  stranded  costs  (excluding
regulatory  assets  which have already  been  addressed  in the 1996  regulatory
agreement with the ACC) would be less than $500 million,  assuming a measurement
period 2001 through 2006.

The Company  intends to use the  Transition  Revenues  Methodology  and does not
intend to divest its generating  assets to an  unaffiliated  party.  The Company
cannot accurately predict the outcome of this matter.

Legislative Initiatives. An Arizona joint legislative committee studied electric
utility industry restructuring issues in 1996 and 1997. In conjunction with that
study,  Arizona  legislative  counsel prepared memoranda in late 1997 related to
the legal  authority  of the ACC to  deregulate  the  Arizona  electric  utility
industry.  The memoranda raise a question as to the degree to which the ACC may,
under the Arizona  Constitution,  deregulate any portion of the electric utility
industry and allow rates to be  determined by market  forces.  This latter issue
(the ability of the ACC to set rates based on the  competitive  market) has been
subsequently  decided  in  favor  of the ACC in one  
<PAGE>
                                      -11-

unrelated and two related lawsuits.

In May 1998, a bill was enacted to facilitate  implementation of retail electric
competition in the state. The bill includes the following major provisions:  (a)
requirements that Arizona's largest  government-operated  electric utility (Salt
River  Project)  and, at their option,  smaller city  electric  systems (i) open
their service  territories  to electric  service  providers to implement  retail
electric  generation  competition  for 20% of each  utility's  1995  retail peak
demand by December  31, 1998 and for all retail  customers by December 31, 2000;
(ii) decrease rates by at least 10% over a ten-year period beginning as early as
January 1, 1991;  (iii)  implement  procedures and public  processes,  including
judicial  review at the  request of either an  interested  party or the  Arizona
Attorney General, for establishing the terms, conditions and pricing of electric
services  as  well  as  certain  other  decisions   affecting   retail  electric
competition,  which  procedures  and processes  are  comparable to those already
applicable to public  service  corporations;  (b) a  description  of the factors
which  form the basis of  consideration  by Salt River  Project  in  determining
stranded costs;  and (c) a requirement  that metering and meter reading services
be provided on a  competitive  basis  during the first two years of  competition
only for  customers  having  demands  in  excess of one  megawatt  (and that are
eligible for competitive generation services),  and thereafter for all customers
receiving competitive electric generation.  In addition, the Arizona legislature
will  review  and make  recommendations  for the  1999  legislature  on  certain
competitive issues.

Federal

The  Energy  Policy  Act of 1992 and recent  rulemakings  by FERC have  promoted
increased  competition in the wholesale electric power markets. The Company does
not expect these rules to have a material impact on its financial statements.

Several  electric  utility  reform  bills  have been  introduced  during  recent
congressional  sessions,  which as currently  written,  would allow consumers to
choose their  electricity  suppliers by 2000 or 2003.  These bills,  other bills
that are expected to be introduced, and ongoing discussions at the federal level
suggest  a wide  range of  opinion  that  will need to be  narrowed  before  any
substantial restructuring of the electric utility industry can occur.

Regulatory Accounting

The Company prepares its financial  statements in accordance with the provisions
of Statement of Financial  Accounting  Standards (SFAS) No. 71,  "Accounting for
the Effects of Certain Types of Regulation."  SFAS No. 71 requires a cost-based,
rate-regulated  enterprise to reflect the impact of regulatory  decisions in its
financial  statements.  The  Company's  existing  regulatory  orders and current
regulatory  environment  support its accounting  practices related to regulatory
assets,  which  amounted to  approximately  $0.9  billion at June 30,  1998.  In
accordance  with  the  1996  regulatory  agreement,   the  ACC  accelerated  the
amortization  of  substantially  all of the  Company's  regulatory  assets to an
eight-year period that began July 1, 1996.
<PAGE>
                                      -12-

During 1997, the Emerging  Issues Task Force (EITF) of the Financial  Accounting
Standards  Board (FASB)  issued EITF 97-4,  which  requires  that SFAS No. 71 be
discontinued no later than when  legislation is passed or a rate order is issued
that  contains  sufficient  detail to determine its effect on the portion of the
business being  deregulated,  which could result in write-downs or write-offs of
physical  and/or  regulatory  assets.  Additionally,  the EITF  determined  that
regulatory  assets should not be written off if they are to be recovered  from a
portion of the entity which continues to apply SFAS No. 71.

Although  the ACC has issued  rules for  transitioning  generation  services  to
competition,  there are many unresolved  issues.  The Company continues to apply
SFAS No. 71 to all of its operations.  If rate recovery of regulatory  assets is
no longer probable, whether due to competition or regulatory action, the Company
would be required to write off the remaining balance as an extraordinary  charge
to expense.

General

Changes  in  ACC  decisions,  Arizona  and  federal  legislation,  and  possible
amendments to the Arizona  Constitution may impact the  implementation of retail
electric  competition  in  Arizona.  Until  the  details  of  implementation  of
competition,  including  addressing  stranded costs, are determined, the Company
cannot accurately predict the impact of full retail competition on its financial
position,  cash flows or results of operation.  As  competition  in the electric
industry continues to evolve,  the Company will continue to evaluate  strategies
and alternatives that will position the Company to compete in the new regulatory
environment.

6. Regulatory Matters -- 1996 Regulatory Agreement

In April 1996, the ACC approved a regulatory  agreement  between the Company and
the ACC Staff. The major provisions of this agreement are:

     +    An annual rate reduction of  approximately  $48.5 million ($29 million
          after  income  taxes),  or 3.4% on average  for all  customers  except
          certain contract customers, effective July 1, 1996.

     +    Recovery of  substantially  all of the  Company's  present  regulatory
          assets through accelerated amortization over an eight-year period that
          began July 1, 1996,  increasing  annual  amortization by approximately
          $120 million ($72 million after income taxes).

     +    A formula  for sharing  future  cost  savings  between  customers  and
          shareholders (price reduction formula)  referencing a return on equity
          (as defined) of 11.25%.
<PAGE>
                                      -13-

     +    A moratorium  on filing for  permanent  rate changes  prior to July 2,
          1999, except under the price reduction formula and under certain other
          limited circumstances.

     +    Infusion of $200 million of common equity into the Company by Pinnacle
          West, in annual payments of $50 million starting in 1996.

Pursuant to the price reduction formula,  in May 1997, the ACC approved a retail
price  decrease of  approximately  $17.6  million  ($10.5  million  after income
taxes),  or 1.2%,  effective July 1, 1997. In March 1998, the Company filed with
the ACC its  calculation  of an annual  price  reduction  of  approximately  $17
million ($10 million after income taxes),  or 1.1%, to become  effective July 1,
1998. The amount and timing of the price decrease are subject to ACC approval.

7. Agreement with Salt River Project

On April 25, 1998, the Company and Salt River Project  entered into a Memorandum
of Agreement in anticipation  of, and to facilitate,  the opening of the Arizona
electric industry. The Agreement contains the following major components:

     +    The  Company  and Salt  River  Project  would  amend  the  Territorial
          Agreement  to remove any  barriers  to the  provision  of  competitive
          electricity supply and non-distribution services.

     +    The Company and Salt River Project would amend the Power  Coordination
          Agreement  to lower the price  that the  Company  will pay Salt  River
          Project for purchased power by  approximately  $17 million (pretax) in
          1999 and by lesser annual amounts through 2006.

     +    The  Company  and Salt River  Project  agreed on  certain  legislative
          positions  regarding  electric utility  restructuring at the state and
          federal level.

An ACC  docket had  previously  been  established  and the ACC held a hearing on
August 6, 1998 so that the ACC could review certain provisions of the Memorandum
of Agreement,  as amended,  including,  whether:  (a) the Territorial  Agreement
remains in the public interest,  (b) the Agreement is a contract in restraint of
trade,  and (c) the Agreement  will  materially  lessen the potential for retail
electric competition in Arizona.

The Antitrust  Unit of the Arizona  Attorney  General's  Office,  which has been
involved in the ongoing  regulatory and  legislative  proceedings  regarding the
restructuring of the Arizona electric industry,  requested  clarification of the
operation of certain of the Agreement's  provisions.  Pursuant to an Addendum to
Memorandum of Agreement, dated as of May 19, 1998 (the "Addendum"),  the Company
and  Salt  River  Project  amended  and  clarified  certain  provisions  of  the
Memorandum  of Agreement in response to certain  issues  raised by the Antitrust
Unit. By letter dated May 19, 1998,  the Antitrust  Unit advised the Company and
Salt River Project that, upon their execution of the Addendum,  it would take no
action  regarding  the  language of the
<PAGE>
                                      -14-

Memorandum  of  Agreement,  although it reserved the right to take action in the
future if new information justified doing so.

8. The Palo Verde  participants  have  insurance for public  liability  payments
resulting  from  nuclear  energy  hazards to the full limit of  liability  under
federal law. This potential  liability is covered by primary liability insurance
provided by commercial  insurance carriers in the amount of $200 million and the
balance by an industry-wide  retrospective  assessment program. If losses at any
nuclear power plant covered by the programs  exceed the accumulated  funds,  the
Company  could  be  assessed  retrospective  premium  adjustments.  The  maximum
assessment  per  reactor  under  the  program  for  each  nuclear   incident  is
approximately  $88  million,  subject  to an  annual  limit of $10  million  per
incident. Based upon the Company's 29.1% interest in the three Palo Verde units,
the Company's  maximum  potential  assessment per incident is approximately  $77
million, with an annual payment limitation of approximately $9 million.

The Palo Verde  participants  maintain "all risk"  (including  nuclear  hazards)
insurance for property damage to, and decontamination of, property at Palo Verde
in the aggregate  amount of $2.75 billion,  a substantial  portion of which must
first be applied to  stabilization  and  decontamination.  The  Company has also
secured  insurance  against  portions of any  increased  cost of  generation  or
purchased power and business interruption resulting from a sudden and unforeseen
outage of any of the three units. The insurance  coverage  discussed in this and
the previous paragraph is subject to certain policy conditions and exclusions.

9. The Company has encountered  tube cracking in the Palo Verde steam generators
and has taken, and will continue to take, remedial actions that it believes have
slowed the rate of tube  degradation.  The  projected  service life of the steam
generators is reassessed  periodically and these analyses  indicate that it will
be economically desirable for the Company to replace the Unit 2 steam generators
between 2003 and 2008. The Company  estimates that its share of the  replacement
costs (in 1998 dollars) will be approximately $50 million, most of which will be
incurred after the year 2000.  During the fourth quarter of 1997, the Palo Verde
participants, including the Company, entered into a contract for the fabrication
of two  replacement  steam  generators.  The cost to the Company is estimated at
approximately  $26 million.  These  generators  will be used as  replacements if
performance of existing generators  deteriorates to less than acceptable levels.
The generators are expected on site in 2002. The Company's share of installation
costs is  approximately  $24 million.  Based on the latest  available  data, the
Company estimates that the Unit 1 and Unit 3 steam generators should operate for
the license  periods (until 2025 and 2027,  respectively),  although the Company
will continue its normal periodic assessment of these steam generators.

10. The Financial Accounting Standards Board issued SFAS No. 131 on "Disclosures
about Segments of an Enterprise and Related  Information" which is effective for
fiscal years  beginning  after  December 15,  1997.  SFAS No. 131 requires  that
public companies report certain  information  about operating  segments in their
financial statements. It also establishes related disclosures about products and
services,  geographic  areas,  and
<PAGE>
                                      -15-

major customers.  The Company is currently  evaluating what impact this standard
will have on its disclosures.

In June 1998 the  Financial  Accounting  Standards  Board  issued  SFAS No.  133
"Accounting  for  Derivative  Instruments  and  Hedging  Activities,"  which  is
effective  for the  Company  in  2000.  SFAS No.  133  requires  that an  entity
recognize all  derivatives  as either assets or liabilities in the balance sheet
and measure those instruments at fair value. The standard also provides specific
guidance for accounting for derivatives  designated as hedging instruments.  The
Company is  currently  evaluating  what  impact this  standard  will have on its
financial statements.

</TABLE>

         Operating  Results -  Three-month  period ended June 30, 1998 compared
         with three-month period ended June 30, 1997

         Earnings decreased $17 million in the three-month  comparison primarily
because  of  the  effects  of  weather,  increased  operations  and  maintenance
expenses, and a retail price reduction,  partially offset by customer growth and
lower fuel expenses.  See Note 6 of Notes to Condensed Financial  Statements for
information on the price reduction.

         Operating  revenues  decreased $17 million  because of weather  effects
($41  million) and the price  reduction ($4  million),  partially  offset by the
effects  of  customer  growth  ($17  million),  increased  sales for  resale ($8
million)  and other ($3  million).  Sales for resale are  wholesale  electricity
sales to third  parties  who  resell the  electricity  to their  customers.  The
increase  in  sales  for  resale  was a result  of  changes  in power  marketing
activity,  which can vary from period to period without corresponding effects on
earnings because of related fluctuations in purchased power costs.

         Operations and maintenance  expenses  increased $14 million as a result
of the  timing of  scheduled  outages at power  plants  and other  miscellaneous
expenses.

         Fuel  expenses  decreased  $4 million  primarily  because of lower fuel
prices and lower retail sales, partially offset by higher sales for resale.

         Operating Results - Six-month period ended June 30, 1998 compared with
         six-month period ended June 30, 1997

         Earnings  decreased $13 million in the six-month  comparison  primarily
because  of  the  effects  of  weather,  increased  operations  and  maintenance
expenses, and a retail price reduction,  partially offset by customer growth and
lower fuel expenses.  See Note 6 of Notes to Condensed Financial  Statements for
additional information about the price reduction.

         Operating  revenues  decreased $16 million  because of weather  effects
($38  million) and the price  reduction ($8  million),  partially  offset by the
effects of customer  growth ($29 million).  Operations and  maintenance expenses
increased  $22  million  as a result of growth  and  increased  expenses  due to
impending competition, the timing of scheduled outages at power plants and other
miscellaneous factors.

         Fuel expenses  decreased $15 million  primarily because of lower prices
and a more favorable mix.

          Operating  Results - Twelve-month  period ended June 30, 1998 compared
          with twelve-month period ended June 30, 1997

         Earnings increased $16 million in the twelve-month comparison primarily
because of customer growth; two fuel-related settlements in the third quarter of
1997; and lower fuel prices. These positive factors more than offset the effects
of  weather  and a retail  price  reduction.  See  Note 6 of Notes to  Condensed
Financial  Statements for additional  information about the price reduction.  In
the period ended June 30, 1997, the Company also recognized $8 million of income
tax benefits associated with capital loss carryforwards.

         Operating revenues increased $79 million primarily because of increases
in sales for resale ($80 million) and customer  growth ($57 million),  partially
offset by the effects of weather  ($37  million)  and the price  reduction  ($18
million).  Sales for resale are wholesale electricity sales to third parties who
resell the electricity to their customers.  The increase in sales for resale was
a result of changes in power marketing  activity,  which can vary from period to
period without corresponding effects on earnings because of related fluctuations
in purchased power costs.

         The  two  fuel-related   settlements  increased  the  Company's  pretax
earnings by approximately $21 million.  The Company's income statement  reflects
these settlements as reductions in fuel expense and as other income.

         Operations and maintenance expenses increased $2 million because higher
expenses  related to growth and impending  competition,  the timing of scheduled
<PAGE>
                                      -18-

outages at power  plants and other  miscellaneous  factors  more than offset the
effects of a charge  for a  voluntary  severance  program  recorded  in 1996 and
related savings in 1997.

         Other Income

         As part of a 1994 rate settlement with the ACC, the Company accelerated
amortization  of  substantially  all deferred ITCs over a five-year  period that
ends on December 31, 1999.  The  amortization  of ITCs is shown on the Company's
income  statement as Other Income -- Income  Taxes and  decreases  annual income
tax expense by approximately $28 million.

Liquidity and Capital Resources

         For  the  six  months  ended  June  30,  1998,  the  Company   incurred
approximately $145 million in capital  expenditures,  which is approximately 45%
of  the  most  recently  estimated  1998  capital  expenditures.  The  Company's
projected capital expenditures for the next three years are: 1998, $323 million;
1999, $322 million; and 2000, $317 million, respectively.  These amounts include
about $30 - $35 million  each year for nuclear fuel  expenditures.  In addition,
the Company is considering  expanding  certain of its  businesses  over the next
several years, which may result in increased expenditures.

         The   Company's   long-term   debt  and  preferred   stock   redemption
requirements and payment  obligations on a capitalized  lease for the next three
years are:  1998,  $176 million;  1999,  $174 million;  and 2000,  $109 million.
During the six months ended June 30, 1998,  the Company  redeemed  approximately
$142  million  of its  long-term  debt  and  approximately  $31  million  of its
preferred stock with cash from operations and long-term and short-term  debt. As
a result of the 1996  regulatory  agreement  (see  Note 6 of Notes to  Condensed
Financial Statements), Pinnacle West invested $50 million in the Company in 1996
and 1997 and will invest similar amounts annually in 1998 and 1999.

         Although  provisions  in the  Company's  bond  indenture,  articles  of
incorporation,  and financing  orders from the ACC establish  maximum amounts of
additional  first mortgage bonds and preferred stock that the Company may issue,
management  does not expect  any of these  restrictions  to limit the  Company's
ability to meet its capital requirements.

Year 2000 Issue

         As the year 2000 approaches  many companies face problems  because many
software  application  and  operational  programs  will not  properly  recognize
calendar  dates   beginning  with  the  year  2000.  The  Company   initiated  a
comprehensive  
<PAGE>
                                      -19-

Company-wide  Year 2000  program  over a year ago to review and resolve all Year
2000 issues in critical systems and equipment in a timely manner in an effort to
ensure the  reliability of electric  service to its  customers.  This included a
Company-wide awareness program of the Year 2000 issue.

         The Company believes that  substantially  all of its major  information
technology (IT) systems are Year 2000 compliant.  The Company has made, and will
continue to make,  certain  modifications to its computer  hardware and software
systems  and  applications  in an effort to ensure  they are capable of handling
changing  business needs,  including  dates in the year 2000 and thereafter.  In
addition, other IT systems and non-IT systems, including embedded technology and
real-time   process   control   systems,   are  being   analyzed  for  potential
modifications.  To date, the Company has inventoried essentially all critical IT
and non-IT systems and the assessment of these systems is ongoing.  The analysis
of the IT and non-IT systems should be complete in late 1998 and any renovation,
validation,  and implementation to be made will be completed by mid-1999 for all
critical systems that affect operations, except for those items that can only be
completed  during  maintenance  outages at Palo Verde,  which will be  completed
during  the last half of 1999.  The  Company  has also  designated  an  internal
audit/quality  review team that is reviewing the  individual  Year 2000 projects
and their Year 2000 readiness on a quarterly  basis.  The cost to the Company of
Year 2000  remediation  has not had,  and is not  expected  to have,  a material
adverse effect on the Company's  financial  position,  cash flows, or results of
operations.

         The Company is in the  process of  communicating  with its  significant
suppliers,  business partners, other utilities, and large customers to determine
the  extent  to  which  it may be  affected  by these  third  parties'  plans to
remediate  their own Year 2000 issues in a timely  manner.  The Company has been
interfacing  with  suppliers  for systems,  services,  and materials in order to
assess whether their  schedules for analysis and remediation of Year 2000 issues
are timely  and to assess  their  ability to  continue  to supply  services  and
materials required by the Company. However, the Company cannot currently predict
the effect on the Company if the systems of these other  companies  are not Year
2000 compliant.

Forward-Looking Statements

         The above discussion contains  forward-looking  statements that involve
risks and uncertainties.  Words such as "estimates,"  "expects,"  "anticipates,"
"plans,"    "believes,"    "projects,"   and   similar   expressions    identify
forward-looking  statements.  These risks and uncertainties include, but are not
limited to, the ongoing  restructuring of the electric industry;  the outcome of
the regulatory  proceedings relating to the restructuring;  regulatory,  tax and
environmental  legislation;  the ability of the Company to successfully  compete
outside its traditional regulated markets;  regional economic conditions,  which
could  affect  customer  growth;  the cost of debt and equity  capital;  weather
variations affecting customer usage;  technological developments in the electric
industry; and Year 2000 issues.

         These  factors and the other matters  discussed  above may cause future
results  to differ  materially  from  historical  results,  or from  results  or
outcomes currently expected or sought by the Company.

ITEM 5. Other Information

        EPA Environmental Regulation

        As previously  reported,  the EPA has been  considering the Grand Canyon
Visability Transport  Commission's  recommendations  prior to promulgating final
regulations on a regional haze  regulatory  program and final  regulations  were
expected  by  June  1998.  See   "Environmental   Matters  -  EPA  Environmental
Regulation" in Part I, Item 1 of the 1997 10-K.  These final regulations are now
expected by December  1998. The Company  cannot  currently  estimate the capital
expenditures,  if any,  which may be required as a result of the EPA studies and
the Commission's recommendations.

        As previously reported, in July 1997, the EPA promulgated final National
Ambient  Air  Quality   Standards  for  ozone  and   particulate   matter.   See
"Environmental Matters - EPA Environmental  Regulation" in Part I, Item 1 of the
1997  10-K.   Congress  recently
<PAGE>
                                      -22-

enacted  legislation  that could delay the  implementation  of the regional haze
requirements and particulate matter ambient standard.

        Spent Nuclear Fuel and Waste Disposal

         As previously  reported,  in November 1997,  the D.C.  Circuit issued a
Writ of Mandamus  precluding  DOE from  excusing  its delay in  accepting  spent
nuclear fuel by January 31, 1998.  See  "Generating  Fuel and Purchased  Power -
Nuclear Fuel Supply - Spent  Nuclear Fuel and Waste  Disposal" in Part I, Item 1
of the 1997 10-K. On May 5, 1998, the D.C.  Circuit issued a ruling  refusing to
order DOE to begin  moving spent  nuclear  fuel.  On July 24, 1998,  the Company
filed a Petition for Review with the D.C. Circuit  regarding DOE's obligation to
begin accepting spent nuclear fuel. Arizona Public Service Company v. Department

of this report for a  discussion  of  competition  and the rules  regarding  the
introduction of retail electric  competition in Arizona. On February 28, 1997, a
lawsuit was filed by the Company to protect its legal rights regarding the rules
and in its complaint the Company asked the Court for (i) a judgment vacating the
retail electric  competition  rules, (ii) a declaratory  judgment that the rules
are unlawful because,  among other things, they were entered into without proper
legal  authorization,  and (iii) a  permanent  injunction  barring  the ACC from
enforcing or implementing the rules and from  promulgating any other regulations
without lawful authority.

R14-2-203. Establishment of service

A.       No change.

B.       Deposits

         1.       A utility shall not require a deposit from a new applicant for
                  residential  service if the  applicant  is able to meet any of
                  the following requirements:

                  a.       The applicant has had service of a comparable  nature
                           with the  utility  within  the past two years and was
                           not  delinquent in payment more than twice during the
                           last  12  consecutive   months  or  disconnected  for
                           nonpayment.

                  b.       The applicant can produce a letter  regarding  credit
                           or  verification   from  an  electric  utility  where
                           service  of a  comparable  nature  was last  received
                           which states  applicant had a timely payment  history
                           at time of service discontinuance.

                  c.       In lieu of a deposit,  a new  applicant may provide a
                           Letter of Guarantee from a governmental or non-profit
                           entity or a surety bond as security for the utility.

         2.       The  utility  shall  issue  a  nonnegotiable  receipt  to  the
                  applicant  for the deposit.  The  inability of the customer to
                  produce  such a receipt  shall in no way  impair  his right to
                  receive  a refund of the  deposit  which is  reflected  on the
                  utility's records.

         3.       Deposits  shall be interest  bearing;  the  interest  rate and
                  method of calculation  shall be filed with and approved by the
                  Commission in a tariff proceeding.

         4.       Each utility shall file a deposit  refund  procedure  with the
                  Commission, subject to Commission review and approval during a
                  tariff proceeding. However, each utility's refund policy shall
                  include  provisions  for  residential   deposits  and  accrued
                  interest  to be  refunded  or letters of  guarantee  or surety
                  bonds to expire after 12 months of service if the customer has
                  not been  delinquent more than twice in the payment of utility
                  bills.
                                       2
<PAGE>
         5.       A utility may require a  residential  customer to establish or
                  reestablish  a deposit if the customer  becomes  delinquent in
                  the payment of 2 bills within a 12 consecutive month period or
                  has been disconnected for service during the last 12 months.

         6.       The  amount  of a deposit  required  by the  utility  shall be
                  determined  according to the following  terms: 

                  a.       Residential  customer  deposits  shall not exceed two
                           times that customer's estimated average monthly bill.

                  b.       Nonresidential customer deposits shall not exceed two
                           and one-half times that customer's  estimated maximum
                           monthly bill.

         7.       The utility may review the customer's  usage after service has
                  been  connected  and adjust the deposit  amount based upon the
                  customer's actual usage.

         8.       A separate deposit may be required for each meter installed.

C.       No change.

D.       Service establishments, re-establishments or reconnection charge

         1.       Each  utility may make a charge as approved by the  Commission
                  for the  establishment,  reestablishment,  or  reconnection of
                  utility services, including transfers between Electric Service
                  Providers.

         2.       Should  service  be  established  during a period  other  than
                  regular working hours at the customer's request,  the customer
                  may be  required to pay an  after-hour  charge for the service
                  connection.  Where  the  utility  scheduling  will not  permit
                  service establishment on the same day requested,  the customer
                  can elect to pay the after-hour charge for establishment  that
                  day or his service will be  established  on the next available
                  normal working day.

         3.       For the  purpose  of this  rule,  the  definition  of  service
                  establishments  are where the customer's  facilities are ready
                  and  acceptable  to the utility and the utility  needs only to
                  install a meter, read a meter, or turn the service on.

         4.       Service  establishments with an Electric Service Provider will
                  be  scheduled  for the next  regular  meter  read  date if the
                  direct  access  service  request is processed 15 calendar days
                  prior to that date and  appropriate  metering  equipment is in
                  place. If a direct access service request is made in less than
                  15 days prior to the next regular  read date,  service will be
                  established  at the next regular  meter read date  thereafter.
                  The utility  may offer  after-hours  or earlier  service for a
                  fee.

         2.       It shall be the responsibility of the utility or Meter Reading
                  Service  Provider to inform the customer how to properly  read
                  his or her meter.

         3.       Where a customer  reads his or her own meter,  the  utility or
                  Meter Reading Service  Provider will read the customer's meter
                  at least once every six months.

         4.       The utility,  billing entity or Meter Reading Service Provider
                  shall  provide the customer with  postage-paid  cards or other

         5.       Each utility or Meter Reading Service  Provider shall specify
                  the  timing  requirements  for the  customer to submit his or
                  her  monthly  meter  reading to  conform  with the  utility's
                  billing cycle.

         6.       Where the Electric  Service  Provider is responsible for meter
                  reading,  reads will be available for the Utility Distribution
                  Company's or billing entity's billing cycle for that customer,
                  or as otherwise  agreed upon by the Electric  Service Provider
                  and the Utility Distribution Company or billing entity.

         7.       In the event the customer fails to submit the reading on time,
                  the  utility  or  billing  entity  may issue the  customer  an
                  estimated bill.

         8.       In the event the Electric  Service  Provider  responsible  for
                  meter  reading  fails to  deliver  reads to the  Meter  Reader
                  Service  Provider  server within 3 days of the scheduled cycle
                  read date, the Affected Utility may estimate the reads.

                                       6
<PAGE>
                  acceptable  measuring devices,  except where it is impractical
                  to  install  meters,  such  as  street  lighting  or  security
                  lighting, or where otherwise authorized by the Commission.

         2.       When there is more than one meter at a location,  the metering
                  equipment  shall be so tagged or plainly marked as to indicate
                  the circuit metered or metering equipment.

         3.       Meters which are not direct  reading shall have the multiplier
                  plainly marked on the meter.

         4.       All charts  taken from  recording  meters shall be marked with
                  the date of the record, the meter number,  customer, and chart

                  file  and  approved  by  the  Commission,  provided  that  the
                  original reading was not in error.

         3.       When a reading is found to be in error, the reread shall be at

with property used in furnishing  service and the exercise of any and all rights
secured to it by law or these rules. 

E.       No change.

A utility or Meter Service  Provider  shall test a meter upon the request of the
customer,  or the customer's  Electric Service  Provider,  Utility  Distribution
Company (as defined in A.A.C.  R14-2-1601) or billing entity  request,  and each
utility or billing  entity shall be authorized  to charge the  customer,  or the
customer's Electric Service Provider,  Utility  Distribution Company (as defined
in A.A.C.  R14-2-1601)  or billing  entity for such meter test  according to the

R14-2-210. Billing and collection

A.       Frequency and estimated bills

         1.       Unless  otherwise  approved by the Commission,  the utility or
                  billing  entity shall render a bill for each billing period to
                  every customer in accordance with its applicable rate schedule
                  and may offer billing options for the services rendered. Meter
                  readings  shall be  scheduled  for periods of not less than 25
                  days without  customer  authorization or more than 35 days. If
                  the utility or Meter Reading Service  Provider changes a meter
                  reading   route  or  schedule   resulting  in  a   significant
                  alteration  of billing  cycles,  notice  shall be given to the
                  affected customers.

         2.       Each  billing  statement  rendered  by the  utility or billing
                  entity  shall be  computed  
                                       8
<PAGE>
                  on the actual usage during the billing period.  If the utility
                  or Meter  Reading  Service  Provider  is  unable  to obtain an
                  actual reading, the utility or billing entity may estimate the
                  consumption  for the billing period giving  consideration  the
                  following  factors where  applicable:  

                  a.       The  customer's  usage  during  the same month of the
                           previous year,

                  b.       The amount of usage during the preceding month.

         3.       Estimated  bills  will be  issued  only  under  the  following
                  conditions  unless  otherwise  approved by the Commission:  

                  a.       When extreme weather conditions, emergencies, or work
                           stoppages prevent actual meter readings.

                  b.       Failure  of a  customer  who  reads  his own meter to
                           deliver  his meter  reading  to the  utility or Meter
                           Reading  Service  Provider  in  accordance  with  the
                           requirements  of the utility or Meter Reading Service
                           Provider billing cycle.

                  c.       When the utility or Meter Reading Service Provider is
                           unable to obtain  access to the  customer's  premises
                           for  the  purpose  of  reading   the  meter,   or  in
                           situations  where the customer makes it unnecessarily
                           difficult  to gain  access  to the  meter,  that  is,
                           locked gates,  blocked  meters,  vicious or dangerous
                           animals, etc. If the utility or Meter Reading Service
                           Provider  is unable to obtain an actual  reading  for
                           these   reasons,   it  shall   undertake   reasonable
                           alternatives  to  obtain a  customer  reading  of the
                           meter.

                   d.      Due  to  customer   equipment   failure,   a  1-month
                           estimation  will be  allowed.  
                                       9
<PAGE>
                           Failure to remedy the  customer  equipment  condition
                           will   result  in   penalties   as   imposed  by  the
                           Commission.

                  e.       To facilitate timely billing for customers using load
                           profiles.

         4.       After the third consecutive month of estimating the customer's
                  bill due to lack of meter access, the utility or Meter Reading
                  Service Provider will attempt to secure an accurate reading of
                  the meter.  Failure on the part of the customer to comply with
                  a   reasonable   request   for  meter   access   may  lead  to
                  discontinuance of service.

         5.       A utility  or  billing  entity  may not render a bill based on
                  estimated usage if: 

                  a.       The estimating  procedures employed by the utility or
                           billing   entity  have  not  been   approved  by  the
                           Commission.

                  b.       The billing  would be the  customer's  first or final
                           bill for service.

                  c.       If the customer is a direct access customer requiring
                           load data.

         6.       When a utility or billing  entity renders an estimated bill in
                  accordance with these rules,  it shall:  
                                       10
<PAGE>
                  a.       Maintain  accurate  records of the reasons  therefore
                           and efforts made to secure an actual reading;

                  b.       Clearly  and  conspicuously  indicate  that  it is an
                           estimated   bill  and  note   the   reason   for  its
                           estimation;

                  c.       Use  customer   supplied  meter  readings,   whenever
                           possible, to determine usage.

B.       Combining meters, minimum bill information

         1.       Each  meter  at  a  customer's   premise  will  be  considered
                  separately  for billing  purposes,  and the readings of two or
                  more meters will not be combined unless otherwise provided for
                  in the utility's tariffs. This provision does not apply in the
                  case of aggregation  of  competitive  services as described in
                  A.A.C. R14-2-1601.

         2.       Each bill for  residential  service will contain the following
                  minimum  information:   

                  a.       The  beginning  and  ending  meter  readings  of  the
                           billing period, the dates thereof,  and the number of
                           days in the billing period;

                  b.       The date when the bill will be considered due and the
                           date when it will be delinquent, if not the same;

                  c.       Billing usage,  demand,  basic monthly service charge
                           and total amount due;

                  d.       Rate schedule number or service offer;

                  e.       Customer's name and service account number;

                  f.       Any previous balance;
                                       11
<PAGE>
                  g.       Fuel adjustment cost, where applicable;

                  h.       License,  occupation,  gross receipts,  franchise and
                           sales taxes;

                           an  inquiry  or  complaint  concerning  the  bill  or
                           services rendered;

                  j.       The Arizona  Corporation  Commission address and toll
                           free telephone numbers;

                  k.       Other unbundled rates and charges.

C.       Billing terms

         1.       All bills for  utility  services  are due and payable no later
                  than 15 days  from  the  date of the  bill.  Any  payment  not
                  received within this time frame shall be considered delinquent
                  and could incur a late payment charge.

         2.       For purposes of this rule,  the date a bill is rendered may be
                  evidenced  by: 

                  a.       The postmark date;

                  b.       The mailing date;

                  c.       The  billing  date  shown on the bill  (however,  the
                           billing date shall not
                                       12
<PAGE>
                           differ from the postmark or mailing date by more than
                           2 days);

                  d.       The transmission date for electronic bills.

         3.       All delinquent bills shall be subject to the provisions of the
                  utility's termination procedures.

         4.       All  payments  shall be made at or mailed to the office of the
                  utility or to the utility's  authorized  payment agency or the
                  office of the  billing  entity.  The date on which the utility
                  actually receives the customer's  remittance is considered the
                  payment date.

D.       Applicable tariffs, prepayment,  failure to receive, commencement date,
         taxes

         1.       Each  customer  shall be billed  under the  applicable  tariff
                  indicated in the customer's application for service.

         2.       Each  utility or billing  entity  shall  make  provisions  for
                  advance payment of utility services.

         3.       Failure to receive  bills or notices  which have been properly
                  placed in the United  States mail shall not prevent such bills
                  from  becoming  delinquent  nor  relieve  the  customer of his
                  obligations therein.

         4.       Charges  for  electric  service  commence  when the service is
                  actually installed and connection made, whether used or not. A
                  minimum  one-month  billing  period is established on the date
                  the service is installed (excluding  landlord/utility  special
                  agreements).
                                       13
<PAGE>
         5.       Charges  for  services  disconnected  after 1 month  shall  be
                  prorated back to the customer of record.

E.       Meter error corrections

         1.       The utility or Meter  Reading  Service  Provider  shall test a
                  meter upon customer request and each utility or billing entity
                  shall be authorized to charge the customer for such meter test
                  according  to the tariff on file  approved by the  Commission.
                  However, if the meter is found to be in error by more than 3%,
                  no meter  testing fee may be charged to the  customer.  If the
                  meter is found to be more  than 3% in  error,  either  fast or
                  slow,  the correction of previous bills will be made under the
                  following  terms  allowing  the  utility or billing  entity to
                  recover or refund the difference:

                  a.       If the  date of the  meter  error  can be  definitely
                           fixed, the utility or billing entity shall adjust the
                           customer's   billings  back  to  that  date.  If  the
                           customer has been underbilled, the utility or billing
                           entity   will  allow  the   customer  to  repay  this
                           difference  over an  equal  length  of time  that the
                           underbillings  occurred.  The customer may be allowed
                           to pay the backbill  without late payment  penalties,
                           unless there is evidence of meter tampering or energy
                           diversion.

                  b.       If  it is  determined  that  the  customer  has  been
                           overbilled   and  there  is  no   evidence  of  meter
                           tampering or energy diversion, the utility or billing
                           entity  will make  prompt  refunds in the  difference
                           between  the  original   billing  and  the  corrected
                           billing within the next billing cycle.
                                       14
<PAGE>
         2.       No  adjustment  shall  be made by the  utility  except  to the
                  customer last served by the meter tested.

         3.       Any  underbilling  resulting  from a  stopped  or slow  meter,
                  utility or Meter Reading Service Provider meter reading error,
                  or a billing  calculation  shall be  limited  to 3 months  for
                  residential   customers  and  6  months  for   non-residential
                  customers.  However,  if an underbilling by the utility occurs
                  due to inaccurate, false or estimated information from a third
                  party,  then that  utility will have a right to back bill that
                  third party to the point in time that may be definitely fixed,
                  or 12 months. No such limitation will apply to overbillings.

F.       Insufficient funds (NSF) or returned checks

         1.       A utility or billing entity shall be allowed to recover a fee,
                  as approved by the Commission in a tariff proceeding, for each
                  instance where a customer tenders payment for electric service
                  with a check which is returned by the customer's bank.

         2.       When  the  utility  or  billing  entity  is  notified  by  the
                  customer's  bank that the check  tendered for utility  service
                  will not clear,  the utility or billing entity may require the
                  customer to make payment in cash,  by money  order,  certified
                  check, or other means to guarantee the customer's payment.
                                       15
<PAGE>
         3.       A  customer  who  tenders  such  a  check  shall  in no way be
                  relieved of the obligation to render payment to the utility or
                  billing  entity under the original terms of the bill nor defer
                  the  utility's   provision  of   termination  of  service  for
                  nonpayment of bills.

G.       Levelized billing plan

         1.       Each  utility  may,  at  its  option,  offer  its  residential
                  customers a levelized billing plan.

         2.       Each utility offering a levelized  billing plan shall develop,
                  upon customer request, an estimate of the customer's levelized
                  billing for a 12-month period based upon:

                  a.       Customer's actual consumption  history,  which may be
                           adjusted  for  abnormal  conditions  such as  weather
                           variations.

                  b.       For  new   customers,   the  utility  will   estimate
                           consumption based on the customer's  anticipated load
                           requirements.

                  c.       The  utility's  tariff  schedules   approved  by  the
                           Commission  applicable  to that  customer's  class of
                           service.

         3.       The utility shall  provide the customer a concise  explanation
                  of how the  levelized  billing  estimate  was  developed,  the
                  impact of levelized  billing on a customer's  monthly  utility
                  bill, and the utility's right to adjust the customer's billing
                  for any variation between the utility's  estimated billing and
                  actual billing.

         4.       For those  customers  being billed  under a levelized  billing
                  plan,  the utility  shall show,  at a minimum,  the  following
                  information on their monthly bill: 
                                       16
<PAGE>
                  a.       Actual consumption

                  b.       Dollar amount  due for actual consumption

                  c.       Levelized billing amount due

                  d.       Accumulated  variation  in  actual  versus  levelized
                           billing amount.

         5.       The utility may adjust the customer's levelized billing in the
                  event the utility's  estimate of the  customer's  usage and/or
                  cost  should vary  significantly  from the  customer's  actual
                  usage  and/or  cost;  such  review to adjust the amount of the
                  levelized  billing  may be  initiated  by the  utility or upon
                  customer request.

H.       Deferred payment plan

         1.       Each utility may,  prior to  termination,  offer to qualifying
                  residential customers a deferred payment plan for the customer
                  to retire unpaid bills for utility service.

         2.       Each deferred  payment  agreement  entered into by the utility
                  and the  customer  shall  provide  that  service  will  not be
                  discontinued if: 

                  a.       Customer  agrees  to pay a  reasonable  amount of the
                           outstanding  bill at the time the parties  enter into
                           the deferred payment agreement.

                  b.       Customer  agrees to pay all future  bills for utility
                           service in accordance with the billing and collection
                           tariffs of the utility.

                  c.       Customer  agrees to pay a  reasonable  portion of the
                           remaining  outstanding balance in installments over a
                           period not to exceed six months.

         3.       For the  purposes  of  determining  a  reasonable  installment
                  payment  schedule  under  these  rules,  the  utility  and the
                  customer shall give consideration to the following conditions:

                  a.       Size of the delinquent account
                                       17
<PAGE>
                  b.       Customer's ability to pay

                  c.       Customer's payment history

                  d.       Length of time that the debt has been outstanding

                  e.       Circumstances   which  resulted  in  the  debt  being
                           outstanding

                  f.       Any   other   relevant   factors   related   to   the
                           circumstances of the customer.

         4.       Any  customer  who  desires to enter  into a deferred  payment
                  agreement   shall   establish  such  agreement  prior  to  the
                  utility's scheduled  termination date for nonpayment of bills.
                  The customer's  failure to execute such an agreement  prior to
                  the  termination  date  will  not  prevent  the  utility  from
                  disconnecting service for nonpayment.

         5.       Deferred  payment  agreements  may be in  writing  and  may be
                  signed   by   the   customer   and   an   authorized   utility
                  representative.

         6.       A deferred  payment  agreement may include a finance charge as
                  approved by the Commission in a tariff proceeding.

         7.       If a  customer  has not  fulfilled  the  terms  of a  deferred
                  payment  agreement,  the  utility  shall  have  the  right  to
                  disconnect  service  pursuant to the utility's  termination of
                  service  rules.  Under  such  circumstances,  it shall  not be
                  required to offer subsequent negotiation of a deferred payment
                  agreement prior to disconnection.

I.       Change of occupancy

         1.       To order  service  discontinued  or to change  occupancy,  the
                  customer must give the utility at least 3 working days advance
                  notice in person, in writing, or by telephone.
                                       18
<PAGE>
         2.       The outgoing  customer  shall be  responsible  for all utility
                  services  provided and/or consumed up to the scheduled turnoff
                  date.

         3.       The outgoing  customer is responsible for providing  access to
                  the  meter  so that  the  utility  may  obtain  a final  meter
                  reading.

A.       Nonpermissible reasons to disconnect service

         1.       A utility  may not  disconnect  service for any of the reasons
                  stated below:

                           provided,  except  in the  instance  where  the prior
                           customer continues to reside on the premises.

                  b.       Failure  of the  customer  to  pay  for  services  or

                  c.       Nonpayment  of a bill  related  to  another  class of

                  d.       Failure  to pay  for a bill  to  correct  a  previous
                           underbilling  due to an  inaccurate  meter  or  meter
                           failure  if  the  customer   agrees  to  pay  over  a
                           reasonable period of time.

                  e.       A utility  shall not  terminate  residential  service

                                    documentation  that,  in  the  opinion  of a
                                    licensed  medical   physician,   termination
                                    would  be   especially   dangerous   to  the
                                    customer's or a permanent  resident residing
                                    on the customer's premises health, or

                                    by the Commission.

                  f.       Residential  service to ill, elderly,  or handicapped
                           persons  who  have an  inability  to pay  will not be
                           terminated  until  all of  the  following  have  been
                           attempted:  

                           i.       The  customer  has  been   informed  of  the
                                    availability    of   funds   from    various
                                    government and social assistance agencies of

         electric  customers  into a  purchasing  group  is  considered  to be a
         competitive service.

R14-2-1606. Services Required To Be Made Available

A.       Each  Affected  Utility  shall make  available to all consumers in that
         class  in its  service  area,  as  defined  on the  date  indicated  in
         R14-2-1602, Standard Offer bundled generation, transmission, ancillary,
         distribution,  and other necessary  services at regulated rates.  After
         January 1, 2001  Standard  Offer  service  shall be provided by Utility
         Distribution Companies who shall also act as Providers of Last Resort.

B.       After  January  1,  2001,  power  purchased  by a Utility  Distribution
         Company  to serve  Standard  Offer  customers,  except  purchases  made
         through spot markets,  shall be acquired  through  competitive bid. Any
         resulting  contract  in excess of 12 months  shall  contain  provisions
         allowing  the Utility  Distribution  Company to ratchet  down its power
         purchases.   A  Utility  Distribution  Company  may  request  that  the
         Commission modify any provision of this subsection for good cause.

C.       Standard Offer Tariffs

         1.       By the date indicated in R14-2-1602, each Affected Utility may
                  file  proposed  tariffs  to  provide  Standard  Offer  Bundled
                  Service  and such  rates  shall  not  become  effective  until
                  approved  by the  Commission.  If no such  tariffs  are filed,
                  rates and services in  existence as of the date in  R14-2-1602
                  shall constitute the Standard Offer.
                                       39
<PAGE>
         2.       Affected  Utilities may file proposed revisions to such rates.
                  It is the  expectation  of the  Commission  that the rates for
                  Standard Offer service will not increase, relative to existing
                  rates, as a result of allowing competition.  Any rate increase
                  proposed by an Affected  Utility for  Standard  Offer  service
                  must be fully justified through a rate case proceeding.

         3.       Such rates shall reflect the costs of providing the service.

         4.       Consumers  receiving  Standard  Offer service are eligible for
                  potential future rate reductions authorized by the Commission,
                  such as reductions authorized in Decision No. 59601.

D.       By the date indicated in R14-2-1602,  each Affected  Utility shall file
         Unbundled  Service  tariffs to provide the services listed below to the
         extent  allowed  by  these  rules  to  all  eligible  purchasers  on  a
         nondiscriminatory basis. Other entities seeking to provide any of these
         services must also file tariffs consistent with these rules:

         1.       Distribution Service;

         2.       Metering and Meter Reading Services;

         3.       Billing and collection services;

         4.       Open access  transmission  service (as approved by the Federal
                  Energy Regulatory Commission, if applicable);

         5.       Ancillary   services  in   accordance   with  Federal   Energy
                  Regulatory  Commission  Order  888 (III  FERC  Stats.  & Regs.
                  paragraph 31,036, 1996) incorporated herein by reference;

         6.       Information services such as provision of customer information
                  to other Electric Service Providers;

         7.       Other  ancillary  services  necessary  for safe  and  reliable
                  system operation.

E.       To manage its risks, an Affected  Utility or Electric  Service Provider
         may include in its tariffs  deposit  requirements  and advance  payment
         requirements for Unbundled Services.
                                       40
<PAGE>
F.       The Affected Utilities must provide transmission and ancillary services
         according to the following guidelines:

         1.       Services must be provided  consistent with applicable  tariffs
                  filed with the Federal Energy Regulatory Commission.

         2.       Unless  otherwise  required  by federal  regulation,  Affected
                  Utilities  must  accept  power and energy  delivered  to their
                  transmission  systems  by others  and offer  transmission  and
                  related  services  comparable  to  services  they  provide  to
                  themselves.

G.       Customer Data

         1.       Upon written  authorization  by the customer,  a  Load-Serving
                  Entity  shall  release  in a timely  and  useful  manner  that
                  customer's demand and energy data for the most recent 12-month
                  period to a customer-specified Electric Service Provider.

         2.       The Electric  Service  Provider  requesting such customer data
                  shall provide an accurate account number for the customer.

         3.       The form of data shall be mutually  agreed upon by the parties
                  and such data shall not be unreasonably withheld.

         4.       Utility Distribution  Companies shall be allowed access to the
                  Meter Reading Service  Provider server for customers served by
                  the Utility Distribution Company's distribution system.

H.       Rates for Unbundled Services

         1.       The  Commission  shall  review and approve  rates for services
                  listed   in   R14-2-1606(D)   and   requirements   listed   in
                  R14-2-1606(E)),   where  it  has  jurisdiction,   before  such
                  services can be offered.

         2.       Such rates shall reflect the costs of providing the services.

         3.       Such  rates may be  downwardly  flexible  if  approved  by the
                  Commission.

I.       Electric  Service  Providers  offering  services under this  R14-2-1606
         shall provide  adequate  
                                       41
<PAGE>
         supporting  documentation  for their  proposed  rates.  Where rates are
         approved by another jurisdiction, such as the Federal Energy Regulatory
         Commission, those rates shall be provided to this Commission.

R14-2-1607. Recovery of Stranded Cost of Affected Utilities

A.       The Affected  Utilities  shall take every  reasonable ,  cost-effective
         measure to mitigate or offset  Stranded Cost by means such as expanding
         wholesale or retail markets,  or offering a wider scope of services for
         profit, among others.

B.       The  Commission  shall allow a reasonable  opportunity  for recovery of
         unmitigated Stranded Cost by Affected Utilities.

C.       The Affected  Utilities  shall file estimates of  unmitigated  Stranded
         Cost.  Such  estimates  shall be fully  supported  by  analyses  and by
         records of market transactions undertaken by willing buyers and willing
         sellers.
                                       42
<PAGE>
D.       An Affected  Utility shall request  Commission  approval,  on or before
         August 21, 1998, of  distribution  charges or other means of recovering
         unmitigated  Stranded  Cost from  customers  who  reduce  or  terminate
         service from the  Affected  Utility as a direct  result of  competition
         governed by this  Article,  or who obtain lower rates from the Affected
         Utility as a direct result of the competition governed by this Article.
                                       43
<PAGE>
E.       The Commission  shall,  after hearing and consideration of analyses and
         recommendations  presented  by  the  Affected  Utilities,   staff,  and
         intervenors,  determine  for each  Affected  Utility the  magnitude  of
         Stranded Cost, and  appropriate  Stranded Cost recovery  mechanisms and
         charges.  In making its  determination  of mechanisms and charges,  the
         Commission shall consider at least the following factors:

         1.       The impact of Stranded Cost recovery on the  effectiveness  of
                  competition;

         2.       The impact of  Stranded  Cost  recovery  on  customers  of the
                  Affected  Utility who do not  participate  in the  competitive
                  market;

         3.       The impact, if any, on the Affected  Utility's ability to meet
                  debt obligations;

         4.       The  impact  of  Stranded  Cost  recovery  on  prices  paid by
                  consumers who participate in the competitive market;

         5.       The degree to which the  Affected  Utility  has  mitigated  or
                  offset Stranded Cost;

         6.       The degree to which some assets have values in excess of their
                  book values;

         7.       Appropriate treatment of negative Stranded Cost;

         8.       The time period over which such  Stranded  Cost charges may be
                  recovered.  The Commission shall limit the application of such
                  charges to a specified time period;

         9.       The ease of determining the amount of Stranded Cost;

         10.      The applicability of Stranded Cost to interruptible customers;

         11.      The amount of  electricity  generated by renewable  generating
                  resources owned by the Affected Utility.
                                       44
<PAGE>
F.       A Competitive  Transition Charge (CTC) may be assessed only on customer
         purchases made in the  competitive  market using the provisions of this
         Article.  Any  reduction  in  electricity  purchases  from an  Affected
         Utility  resulting from  self-generation,  demand side  management,  or
         other demand reduction  attributable to any cause other than the retail
         access  provisions  of this  Article  shall not be used to calculate or
         recover any Stranded Cost from a consumer.

G.       Stranded  Cost shall be  recovered  from  customer  classes in a manner
         consistent  with the specific  company's  current rate treatment of the
         stranded  asset, in order to effect a recovery of Stranded Cost that is
         in  substantially  the same proportion as the recovery of similar costs
         from customers or customer classes under current rates.

H.       The  Commission  may order an  Affected  Utility to file  estimates  of
         Stranded  Cost and  mechanisms  to recover or, if  negative,  to refund
         Stranded Cost.

I.       The  Commission  may  order  regular  revisions  to  estimates  of  the
         magnitude of Stranded Cost.

R14-2-1608. System Benefits Charges

A.       By the date indicated in R14-2-1602,  each Affected  Utility or Utility
         Distribution  Company shall file for Commission  review  non-bypassable
         rates or related mechanisms to recover the applicable pro-rata costs of
         System Benefits from all consumers located in the Affected Utility's or
         Utility  Distribution  Companies'  service area who  participate in the
         competitive   market.   Affected  Utilities  or  Utility   Distribution
         Companies shall file for review of the Systems  Benefits Charge every 3
         years. The amount collected annually through the System Benefits charge
         shall  be  sufficient  to  fund  the  Affected  Utilities'  or  Utility
         Distribution  Companies'  Commission-approved  low income,  demand side
         management, market transformation, environmental, renewables, long-term
         public benefit research and development,  and nuclear fuel disposal and
         nuclear  power  plant  decommissioning  programs in effect from time to
         time.  Now, the  Commission  will  approve a solar water heater  rebate
         program:  $200,000  to be  allocated  proportionally  among the state's
         Utility  Distribution  Companies in 1999, $400,000 in 2000, $600,000 in
         2001,  $800,000 in 2002, and $1 million in 2003; the rebate will not be
         more than $500 per system for  Commission  staff-approved  solar  water
         heaters.  After 2003,  future  Commissions  may review this program for
         efficacy.

B.       Each  Affected  Utility or Utility  Distribution  Company shall provide
         adequate  supporting  documentation  for its proposed  rates for System
         Benefits.

C.       An Affected Utility or Utility  Distribution  Company shall recover the
         costs  of  System  Benefits  only  upon  hearing  and  approval  by the
         Commission of the recovery  charge and  mechanism.  The  Commission may
         combine  its  review  of System  Benefits  charges  with its  review of
         filings pursuant to R14-2-1606.

R14-2-1609. Solar Portfolio Standard

A.       Starting on January 1, 1999,  any  Electric  Service  Provider  selling
         electricity  or  aggregating  customers  for  the  purpose  of  selling
         electricity  under the  provisions of this Article must derive at least
         .2% of the total retail energy sold competitively from new solar energy
         resources,  whether  that solar energy is purchased or generated by the
         seller.  Solar  resources  include  photovoltaic  resources  and  solar
         thermal  resources that generate  electricity.  New solar resources are
         those installed on or after January 1, 1997.

B.       Starting  January  1 of each year from  2000  through  2003,  the solar
         resource  requirement  shall  increase  by .2%  with  the  result  that
         starting  January  1,  2003,  any  Electric  Service  Provider  selling
         electricity  or  aggregating  customers  for  the  purpose  of  selling
         electricity  under the  provisions of this Article must derive at least
         1.0% of the  total  retail  energy  sold  competitively  from new solar
         energy resources.  The 1.0% requirement shall be in effect from January
         1, 2003 through December 31, 2012.
                                       47
<PAGE>
C.       The solar portfolio  requirement shall only apply to competitive retail
         electricity  in the years  1999 and 2000 and shall  apply to all retail
         electricity in the years 2001 and thereafter.

D.       Electric  Service  Providers  shall be  eligible  for a number of extra
         credit  multipliers  that  may be  used  to meet  the  solar  portfolio
         standard requirements:

         1.       Early  Installation  Extra  Credit  Multiplier:  For new solar
                  electric systems installed and operating prior to December 31,
                  2003,  Electric  Service  Providers would qualify for multiple
                  extra   credits  for  kWh  produced  for  5  years   following
                  operational  start-up of the solar electric system. The 5-year
                  extra credit would vary  depending  upon the year in which the
                  system started up, as follows:

                           YEAR             EXTRA CREDIT MULTIPLIER
                           ----             -----------------------
                           1997                       .5

                           1998                       .5

                           1999                       .5

                           2000                       .4

                           2001                       .3

                           2002                       .2

                           2003                       .1

                  The Early  Installation  Extra Credit  Multiplier would end in
                  2003.

         2.       Solar Economic Development Extra Credit Multipliers: There are
                  2 equal parts to this  multiplier,  an  in-state  installation
                  credit and an in-state content multiplier.
                                       48
<PAGE>
                  a.       In-State  Power  Plant   Installation   Extra  Credit
                           Multiplier:  Solar electric power plants installed in
                           Arizona shall receive a .5 extra credit multiplier.

                  b.       In-State Manufacturing and Installation Content Extra
                           Credit Multiplier:  Solar electric power plants shall
                           receive up to a .5 extra credit multiplier related to
                           the manufacturing and installation content that comes
                           from Arizona.  The  percentage of Arizona  content of
                           the total installed plant cost shall be multiplied by
                           .5  to  determine   the   appropriate   extra  credit
                           multiplier. So, for instance, if a solar installation
                           included 80% Arizona  content,  the  resulting  extra
                           credit multiplier would be .4 (which is .8 X .5).

         3.       Distributed  Solar  Electric  Generator  and  Solar  Incentive
                  Program  Extra  Credit   Multiplier:   Any  distributed  solar
                  electric generator that meets more than one of the eligibility
                  conditions  will  be  limited  to  only  one .5  extra  credit
                  multiplier from this  subsection.  Appropriate  meters will be
                  attached to each solar  electric  generator  and read at least
                  once annually to verify solar  performance.  

                  a.       Solar  electric  generators  installed  at or on  the
                           customer  premises  in  Arizona.   Eligible  customer
                           premises  locations will include both  grid-connected
                           and remote,  non-grid-connected  locations.  In order
                           for  Electric  Service  Providers  to  claim an extra
                           credit multiplier, the Electric Service Provider must
                           have  contributed at least 10% of the total installed
                           cost or  have  financed  at  least  80% of the  total
                           installed cost.

                  b.       Solar electric generators located in Arizona that are
                           included in any  Electric  Service  Provider's  Green
                           Pricing program.

                  c.       Solar electric generators located in Arizona that are
                           included  in  any  Electric  Service  Provider's  Net
                           Metering or Net Billing program.

                  d.       Solar electric generators located in Arizona that are
                           included in any  Electric  Service  Provider's  solar
                           leasing program.

                  e.       All Green  Pricing,  Net Metering,  Net Billing,  and

                           must have been reviewed and approved by the Director,
                           Utilities  Division in order for the Electric Service
                           Provider to accrue extra credit multipliers from this
                           subsection.

         4.       All  multipliers  are  additive,  allowing a maximum  combined
                  extra  credit  multiplier  of  2.0  in  years  1997-2003,  for
                  equipment  installed  and  manufactured  in Arizona and either
                  installed at customer  premises or  participating  in approved
                  solar incentive programs.  So, if an Electric Service Provider
                  qualifies for a 2.0 extra credit  multiplier and it produces 1
                  solar kWh, the Electric  Service Provider would get credit for
                  3 solar kWh (1 produced plus 2 extra credit).

E.       No change.

F.       If  an  Electric  Service  Provider  selling   electricity   under  the
         provisions   of  this  Article  fails  to  meet  the   requirement   in
         R14-2-1609(A) or (B) in any year, the Commission shall impose a penalty
         on that Electric  Service  Provider that the Electric  Service Provider
         pay an amount equal to 30 cents per kWh to the Solar  Electric Fund for
         deficiencies  in the  provision  of  solar  electricity  .  This  Solar
         Electric  Fund will be  established  and  utilized  to  purchase  solar
         electric generators or solar electricity in the following calendar year
         for the use by public  entities  in Arizona  such as  schools,  cities,
         counties,  or state agencies.  Title to any equipment  purchased by the
         Solar  Electric  Fund will be  transferred  to the  public  entity.  In
         addition,  if the provision of solar energy is consistently  deficient,
         the  Commission  may  void an  Electric  Service  Provider's  contracts
         negotiated under this Article.

         1.       The  Director,  Utilities  Division  shall  establish  a Solar
                  Electric  Fund in  1999 to  receive  deficiency  payments  and
                  finance solar electricity projects.

         2.       The Director,  Utilities  Division shall select an independent
                  administrator  for the selection of projects to be financed by
                  the Solar  Electric Fund. A portion of the Solar Electric Fund
                  shall be used for  administration of the Fund and a designated
                  portion  of the Fund will be set aside for  ongoing  operation
                  and maintenance of projects financed by the Fund.

G.       Photovoltaic  or solar thermal  electric  resources that are located on
         the consumer's premises shall count toward the solar portfolio standard
         applicable  to the  current  Electric  Service  Provider  serving  that
         consumer.

H.       Any solar electric generators  installed by an Affected Utility to meet
         the solar portfolio  standard shall be counted toward meeting renewable
         resource  goals for  Affected  Utilities  established  in Decision  No.
         58643.

I.       Any Electric Service Provider or independent  solar electric  generator
         that  produces  or  purchases  any solar  kWh in  excess of its  annual
         portfolio  requirements may save or bank those excess solar kWh for use
         or sale in future  years.  Any eligible  solar kWh produced  subject to
         this rule may be sold or traded to any Electric  Service  Provider that
         is  subject  to  this  rule.  Appropriate  documentation,   subject  to
         Commission review, shall be given to the purchasing entity and shall be
         referenced  in the reports of the  Electric  Service  Provider  that is
         using the purchased kWh to meet its portfolio requirements.

J.       Solar portfolio standard  requirements shall be calculated on an annual
         basis, based upon electricity sold during the calendar year.

K.      An  Electric  Service  Provider  shall be  entitled to receive a partial
        credit against the solar portfolio  requirement if the Electric  Service
        Provider or its affiliate owns or makes a significant  investment in any
        solar  electric  manufacturing  plant that is located  in  Arizona.  The
        credit  will be equal to the  amount of the  nameplate  capacity  of the
        solar  electric  generators  produced  in Arizona and sold in a calendar
        year times 2,190 hours (approximating a 25% capacity factor).

         1.       The credit against the portfolio  requirement shall be limited
                  to  the   following   percentages   of  the  total   portfolio
                  requirement:

                  1999              Maximum of 50 % of the portfolio requirement

                  2000              Maximum of 50 % of the portfolio requirement

                  2001              Maximum of 25 % of the portfolio requirement
                                       51
<PAGE>
                  2002              Maximum of 25 % of the portfolio requirement

                  2003 and on       Maximum of 20 % of the portfolio requirement

         2.       No extra credit  multipliers  will be allowed for this credit.
                  In order to avoid double-counting of the same equipment, solar
                  electric  generators  that are used by other Electric  Service
                  Providers to meet their Arizona solar  portfolio  requirements
                  will not be allowable  for credits  under this Section for the
                  manufacturer/Electric  Service  Provider to meet its portfolio
                  requirements.

L.      The  Director,  Utilities  Division  shall develop  appropriate  safety,
        durability,  reliability,  and performance standards necessary for solar
        generating  equipment  to  qualify  for the  solar  portfolio  standard.
        Standards  requirements  will apply only to  facilities  constructed  or
        acquired after the standards are publicly issued.

R14-2-1610. Transmission and Distribution Access

A.       The Affected Utilities shall provide  non-discriminatory open access to
         transmission  and  distribution  facilities to serve all customers.  No
         preference  or  priority  shall be given to any  distribution  customer
         based on whether the  customer is  purchasing  power under the Affected
         Utility's Standard Offer or in the competitive market. Any transmission
         capacity  that is  reserved  for  use by the  retail  customers  of the
         Affected  Utility's  Utility  Distribution  Company  shall be allocated
         among Standard Offer  customers and competitive  market  customers on a
         pro-rata basis.

B.       The  Commission  supports  the  development  of an  Independent  System
         Operator  (ISO)  or,  absent  an  Independent   System   Operator,   an
         Independent Scheduling Administrator (ISA).
                                       52
<PAGE>
C.       The Commission believes that an Independent Scheduling Administrator is
         necessary in order to provide  non-discriminatory  retail access and to
         facilitate a robust and efficient electricity market. Therefore,  those
         Affected Utilities that own or operate Arizona transmission  facilities
         shall file with the Federal Energy Regulatory Commission by October 31,
         1998 for approval of an Independent Scheduling Administrator having the
         following characteristics:

         1.       The  Independent  Scheduling   Administrator  shall  calculate
                  Available Transmission Capacity (ATC) for Arizona transmission
                  facilities  that  belong to the  Affected  Utilities  or other
                  Independent Scheduling Administrator  participants,  and shall
                  develop and operate an overarching statewide OASIS.

         2.       The Independent  Scheduling  Administrator shall implement and
                  oversee the  non-discriminatory  application  of  protocols to
                  ensure statewide  consistency for transmission  access.  These
                  protocols shall include, but are not limited to, protocols for
                  determining   transmission   system   transfer   capabilities,
                  committed uses of the transmission system,  available transfer
                  capabilities, and Must-Run Generating Units.

         3.       The Independent Scheduling Administrator shall provide dispute
                  resolution   processes  that  enable  market  participants  to
                  expeditiously  resolve claims of  discriminatory  treatment in
                  the   reservation,   scheduling,   use  and   curtailment   of
                  transmission services.

         4.       All  requests   (wholesale,   Standard   Offer   retail,   and
                  competitive  retail) for reservation and scheduling of the use
                  of Arizona transmission facilities that belong to the Affected
                  Utilities  or  other  Independent   Scheduling   Administrator
                  participants  shall be made to, or  through,  the  Independent
                  Scheduling   Administrator   using  a   single,   standardized
                  procedure.
                                       53
<PAGE>
D.       The  Affected  Utilities  that  own  or  operate  Arizona  transmission
         facilities shall file a proposed Independent  Scheduling  Administrator
         implementation  plan with the  Commission  by  September  1, 1998.  The
         implementation plan shall address Independent Scheduling  Administrator
         governance,  incorporation,  financing and staffing; the acquisition of
         physical   facilities   and   staff  by  the   Independent   Scheduling
         Administrator;  the schedule for the phased  development of Independent
         Scheduling  Administrator  functionality;  contingency  plans to ensure
         that  critical  functionality  is in place by January 1, 1999;  and any
         other   significant   issues  related  to  the  timely  and  successful
         implementation of the Independent Scheduling Administrator.

E.       Each of the Affected Utilities shall make good faith efforts to develop
         a  regional,  multi-state  Independent  System  Operator,  to which the
         Independent  Scheduling  Administrator  should  transfer  its  relevant
         assets and functions as the Independent System Operator becomes able to
         carry out those functions.

F.       It is  the  intent  of the  Commission  that  prudently-incurred  costs
         incurred by the Affected  Utilities in the  establishment and operation
         of the  Independent  Scheduling  Administrator,  and  subsequently  the
         Independent  System Operator,  should be recovered from customers using
         the transmission  system,  including the Affected Utilities'  wholesale
         customers,  Standard Offer retail  customers,  and  competitive  retail
         customers  on  a   non-discriminatory   basis  through  Federal  Energy
         Regulatory Commission-regulated prices. Proposed rates for the recovery
         of such  costs  shall  be  filed  with the  Federal  Energy  Regulatory
         Commission  and the  Commission.  In the event that the Federal  Energy
         Regulatory  Commission does not permit  recovery of prudently  incurred
         Independent  Scheduling  Administrator costs within 90 days of the date
         of making an application with the Federal Energy Regulatory Commission,
         the Commission may authorize  Affected  Utilities to recover such costs
         through a distribution surcharge.

G.       The Commission supports the use of "Scheduling Coordinators" to provide
         aggregation  of  customers'  schedules  to the  Independent  Scheduling
         Administrator and the respective Control Area Operators  simultaneously
         until the implementation of a regional 
                                       54
<PAGE>
         Independent  System  Operator,  at  which  time the  schedules  will be
         submitted to the  Independent  System  Operator.  The primary duties of
         Scheduling  Coordinators  are to: 

         1.       Forecast their customers' load requirements;

         2.       Submit  balanced  schedules  (i.e.,  schedules for which total
                  generation   is  equal  to  total   load  of  the   Scheduling
                  Coordinator's customers plus appropriate  transmission losses)
                  and  North  American  Electric   Reliability   Council/Western
                  Systems Coordinating Council tags;
         
         3.       Arrange for the acquisition of the necessary  transmission and
                  ancillary services;

         4.       Respond to  contingencies  and curtailments as directed by the
                  Control Area Operators,  Independent Scheduling  Administrator
                  or Independent System Operator;

         5.       Actively  participate in the schedule checkout process and the
                  settlement   processes   of  the   Control   Area   Operators,
                  Independent  Scheduling  Administrator  or Independent  System
                  Operator.

H.       The  Affected  Utilities  shall  provide  services  from  the  Must-Run
         Generating  Units to Standard  Offer retail  customers and  competitive
         retail customers on a comparable, non-discriminatory basis at regulated
         prices.  The Affected  Utilities  shall specify the  obligations of the
         Must-Run  Generating Units in appropriate  sales contracts prior to any
         divestiture.  Under  auspices of the Electric  System  Reliability  and
         Safety Working Group,  the Affected  Utilities shall develop  statewide
         protocols  for  pricing and  availability  of  services  from  Must-Run
         Generating  Units with input from other  stakeholders.  These protocols
         shall be  presented  to the  Commission  for  review and filed with the
         Federal  Energy  Regulatory  Commission,  if necessary,  by October 31,
         1998.

D.       If an electric utility is an Arizona political subdivision or municipal
         corporation,  then the  existing  service  territory  of such  electric
         utility  shall  be  deemed  open  to   competition   if  the  political
         subdivision  or  municipality  has  entered  into an  intergovernmental
         agreement with the Commission that establishes  nondiscriminatory terms
         and conditions for Distribution  Services and other Unbundled Services,
         provides a procedure for complaints arising therefrom, and provides for
         reciprocity with Affected Utilities or their affiliates. The Commission
         shall  conduct  a  hearing  to  consider  any  such   intergovernmental
         agreement.

E.       An affiliate of an Arizona  electric  utility  which is not an Affected
         Utility shall not be allowed to compete in the service  territories  of
         Affected   Utilities  unless  the  affiliate's   parent  company,   the
         non-affected  electric  utility,  submits a statement to the Commission
         indicating  that the parent company will  voluntarily  open its service
         territory for competing  sellers in a manner  similar to the provisions
         of this Article and the Commission makes a finding to that effect.

         for service of 1 MW or more must be filed with the Director,  Utilities
         Division as soon as practicable. If a contract does not comply with the
         provisions  of this  Article  and the  Affected  Utility's  or Electric
         Service  Provider's  approved  tariffs,  it shall not become  effective
         without a Commission  order.  Such contracts shall be kept confidential
         by the Commission.

D.       Contracts  entered into on or after the date indicated in R14-2-1604(D)
         which comply with approved tariffs need not be filed with the Director,

         5.       R14-2-213,

         6.       R14-2-208(E) and (F).

C.       No consumer  shall be deemed to have  changed  providers of any service
         authorized  in this  Article  (including  changes  from  supply  by the
         Affected Utility to  another provider) without written authorization by
         the  consumer  for  service  from the new  provider.  If a consumer  is
         switched  (or  slammed) to a different  ("new")  provider  without such
         written  authorization,  the new  provider  shall cause  service by the
         previous  provider  to be resumed and the new  provider  shall bear all
         costs  associated  with  switching  the  consumer  back to the previous
         provider.  A  written  authorization  that is  obtained  by  deceit  or

         reliable electric service.  Utility  Distribution  Companies shall make
         reasonable efforts to notify customers of scheduled  outages,  and also
         provide notification to the Commission.

E.       Each Electric Service Provider shall provide at least 45 days notice to
         all  of its  affected  consumers  of  its  intent  to  cease  providing
         generation,   transmission,   distribution,   or   ancillary   services
         necessitating that the consumer obtain service from another supplier of
         generation, transmission, distribution, or ancillary services.

F.       No change.

G.       No change.

H.       Electric  Service  Providers shall give at least 5 days notice to their
         customer of scheduled  return to the Standard Offer, but that return of
         that  customer  to the  Standard  Offer  would be at the  next  regular
         billing cycle.  Responsibility  for charges incurred between the notice
         and the next scheduled  read date shall rest with the Electric  Service
         Provider.

         Utility or Utility  Distribution  Company to  separate  such  assets or
         services  utilized  in  these  circumstances.  Affected  Utilities  and
         Utility  Distribution  Companies may provide  metering,  meter

                  its affiliates joint corporate oversight,  governance, support
                  systems and  personnel.  Any shared  support  shall be priced,
                  reported  and  conducted  in  accordance  with all  applicable
                  Commission  pricing and  reporting  requirements.  An Affected
                  Utility or Utility  Distribution  Company shall not use shared
                  corporate   support   functions   as  a  means   to   transfer
                  confidential  information,  allow preferential  treatment,  or
                  create significant  opportunities for  cross-subsidization  of
                  its  affiliates,  and shall provide  mechanisms and safeguards
                  against such activity in its compliance plan.

                  discloses in plain legible or audible  language,  on the first
                  page or at the first instance the Affected  Utility or Utility
                  Distribution  Company  name  or logo  appears,  that:

                  offer or provide to its  affiliates  advertising  space in any

                  do not  prohibit  transfer  of goods and  services  between an
                  Affected  Utility  or  Utility  Distribution  Company  and its
                  affiliates,  all  such  transfers  shall  be  subject  to  the
                  following price provisions:

                  a.       Goods and services provided by an Affected Utility or
                           Utility Distribution Company to an affiliate shall be
                           transferred  at the  price  and  under  the terms and
                           conditions  specified in its tariff.  If the goods or
                           service to be transferred is a non-tariffed item, the
                           transfer price shall be the higher of fully allocated
                           cost or the market price. Transfers from an affiliate
                           to its affiliated Utility  Distribution Company shall
                           be  priced at the  lower of fully  allocated  cost or
                           fair market value.

                  b.       Goods and services  produced,  purchased or developed
                           for sale on the open market by the  Affected  Utility
                           or Utility  Distribution  Company will be provided to
                           its  affiliates  and  unaffiliated   companies  on  a
                           nondiscriminatory    basis,   except   as   otherwise
                           permitted by these rules or applicable law.

         8.       No Cross-subsidization: A competitive affiliate of an Affected
                  Utility  or  Utility   Distribution   Company   shall  not  be
                  subsidized  by any  rate  or  charge  for  any  noncompetitive
                  service,  and shall  not be  provided  access to  confidential
                  utility information.

         Distribution   Company  or  Electric  Service  Provider  shall  provide
         customer   information  to  its  affiliates  and   nonaffiliates  on  a
         non-discriminatory  basis,  provided prior affirmative customer written
         consent is obtained.  Any non-customer specific non-public  information
         shall  be made  contemporaneously  available  by an  Affected  Utility,
         Utility  Distribution  Company  or  Electric  Service  Provider  to its
         affiliates  and all  other  service  providers  on the same  terms  and
         conditions.

C.       An Affected Utility or Utility Distribution Company shall adhere to the
         following guidelines:

         1.       Any list of Electric Service Providers provided by an Affected
                  Utility or Utility Distribution Company to its customers which
                  includes  or  identifies  the  Affected  Utility's  or Utility
                  Distribution  Company's  competitive  electric affiliates must
                  include or identify  non-affiliated  entities  included on the
                  list of those  Electric  Service  Providers  authorized by the
                  Commission to provide service within the Affected Utility's or
                  Utility   Distribution   Company's   certificated   area.  The
                  Commission  shall  maintain an updated  list of such  Electric
                  Service  Providers  and make that list  available  to Affected
                  Utilities or Utility Distribution Companies at no cost.

         2.       An  Affected  Utility  or  Utility  Distribution  Company  may
                  provide non-public supplier information and data, which it has
                  received from  unaffiliated  suppliers,  to its  affiliates or
                  nonaffiliated entities only if the Affected Utility or Utility
                  Distribution  Company  receives prior  authorization  from the
                  supplier.

         3.       Except as  otherwise  provided  in these  rules,  an  Affected
                  Utility or  Utility  Distribution  Company  shall not offer or
                  provide customers advice, which includes promoting,  marketing
                  or selling, about its affiliates or other service providers.

         4.       An  Affected  Utility or Utility  Distribution  Company  shall
                  maintain  contemporaneous records documenting all tariffed and
                  nontariffed  transactions  with its affiliates,  including but
                  not limited  to, all waivers of tariff or contract  provisions
                  and all  discounts.  These records  shall be maintained  for a
                  period of 3 years, or longer if required by this Commission or
                  another governmental agency.

D.       Nondiscrimination An Affected Utility, Utility Distribution Company, or
         their  affiliates  shall  not  represent  that,  as  a  result  of  the
         affiliation,  customers of such  affiliates  will receive any treatment
         different from that provided to other, non-affiliated entities or their
         customers. An Affected Utility,  Utility Distribution Company, or their
         affiliates  shall not provide their  
                                       69
<PAGE>
         affiliates,  or  customers of their  affiliates,  any  preference  over
         non-affiliated  suppliers  or  their  customers  in  the  provision  of
         services. For example:

         1.       Except when made generally  available by an Affected  Utility,
                  Utility Distribution  Company or their affiliates,  through an
                  open  competitive  bidding process,  if the Affected  Utility,
                  Utility  Distribution  Company  or their  affiliates  offers a
                  discount or waives all or any part of any charge or fee to its
                  affiliates,  or offers a discount or waiver for a  transaction
                  in which  their  affiliates  are  involved,  the entity  shall
                  contemporaneously  make such  discount or waiver  available to
                  all.

         2.       If  a  tariff   provision   allows  for   discretion   in  its
                  application,  an  Affected  Utility  or  Utility  Distribution
                  Company   shall  apply  that   provision   equally  among  its
                  affiliates  and  all  other  market   participants  and  their
                  respective customers.

         3.       Requests from affiliates and non-affiliated entities and their
                  customers  for services  provided by the  Affected  Utility or
                  Utility   Distribution   Company   shall  be  processed  on  a
                  nondiscriminatory basis.

         4.       An Affected Utility or Utility  Distribution Company shall not
                  condition  or  otherwise  tie  the  provision  of any  service
                  provided,  nor the availability of discounts of rates or other
                  charges or fees, rebates or waivers of terms and conditions of
                  any services,  to the taking of any goods or services from its
                  affiliates.

         5.       In the course of business  development and customer relations,
                  except as  otherwise  provided  in these  rules,  an  Affected
                  Utility or Utility Distribution Company shall refrain from:

                  a.       Providing leads to its affiliates;

                  b.       Soliciting business on behalf of affiliates;

                  c.       Acquiring   information  on  behalf  of,  or  provide
                           information to, its affiliates;
                                       70
<PAGE>
                  d.       Sharing market analysis  reports or any  non-publicly
                           available  reports,  including  but  not  limited  to
                           market, forecast, planning or strategic reports, with
                           its affiliates.

E.       Compliance Plans No later than December 31, 1998, each Affected Utility
         or  Utility   Distribution   Company  shall  file  a  compliance   plan
         demonstrating the procedures and mechanisms  implemented to ensure that
         activity  prohibited by these rules will not take place. The compliance
         plan shall be submitted to the Director,  Utilities  Division and shall
         be in effect until a  determination  is made  regarding its  compliance
         under these rules.  The compliance  plan shall  thereafter be submitted
         annually to reflect any material  changes.  No later than  December 31,
         1999,  and every year  thereafter  until December 31, 2002, an Affected
         Utility or Utility  Distribution Company shall have a performance audit
         prepared by an independent auditor to examine compliance with the rules
         set  forth  herein.  Such  audits  shall  be filed  with the  Director,
         Utilities  Division.  After  December 31, 2002 the Director,  Utilities
         Division may request a Utility  Distribution Company to conduct such an
         audit.

F.       Waivers

         1.       Any affected  entity may petition the  Commission for a waiver
                  by filing a verified application for waiver setting forth with
                  specificity  the  circumstances  whereby  the public  interest
                  justifies a waiver from all or part of the  provisions of this
                  rule.

         2.       The Commission may grant such  application upon a finding that
                  a waiver is in the public interest.

R14-2-1618 Disclosure of Information

A.       There are  efforts  under the  auspices of the  Western  Conference  of
         Public Service  Commissioners to develop a tracking mechanism as to the
         source of electrons.  To facilitate  customer  choice,  the  Commission
         intends to  participate  in developing  this  tracking  mechanism and a
         side-by-side   comparison   for  retail   customers  on  price,   price
         variability, fuel mix, and emissions of electricity offered for sale in
         Arizona  and the West.  Until  this is  accomplished,  R14-2-1618  is a
         placeholder.
