                    NOTES TO CONDENSED FINANCIAL STATEMENTS

                                  (Unaudited)


1. GENERAL

   Basis of Presentation -- The condensed financial statements included herein
have been prepared by Texas Utilities Electric Company (Company) on the same
basis as those in the 1994 Annual Report on Form 10-K and, in the opinion of the
Company, all adjustments (constituting only normal recurring accruals) necessary
to a fair statement of the results of operation have been included therein. The
statements are presented pursuant to the rules and regulations of the Securities
and Exchange Commission. Certain information and footnote disclosures normally
included in annual financial statements prepared in accordance with generally
accepted accounting principles have been omitted pursuant to such rules and
regulations. The Company believes that the disclosures are adequate to make the
information presented not misleading.

   The unaudited financial information included herein has been reviewed by
Deloitte & Touche LLP, independent certified public accountants, whose report
with respect thereto is filed herewith in Part I of this report.  The condensed
financial statements should be considered in conjunction with the financial
statements, and the notes thereto, of the Company included in the 1994 Annual
Report on Form 10-K and the information under Management's Discussion and
Analysis of Financial Condition and Results of Operation herein.

   Reclassification -- Certain financial statement items for 1994 have been
reclassified to conform to the 1995 presentation.

   Allowance for Funds Used During Construction (AFUDC) -- The Company is
capitalizing AFUDC monthly, on expenditures for ongoing construction work in
progress (CWIP) and nuclear fuel in process not otherwise allowed in rate base
by regulatory authorities.  Effective January 1, 1995, the Company began using a
gross rate of 6.75% for AFUDC for all construction.  For 1994 and 1993, the
gross rates were 8.6% and 10.4%, respectively.

2. SHORT-TERM FINANCING

   At March 31, 1995, the Company and Texas Utilities Company (Texas Utilities)
had joint lines of credit aggregating $1,000,000,000 under credit facility
agreements with a group of commercial banks.  On April 28, 1995, the Company and
Texas Utilities renegotiated these credit facility agreements and entered into
amendments that continued the terms of such credit facility agreements (Amended
Agreements).  The Amended Agreements have two facilities, for each of which
Texas Utilities pays a fee.  Facility A provides for borrowings up to
$300,000,000 and terminates April 28, 1996.  Facility B provides for borrowings
up to $700,000,000 and terminates April 28,2000.  Borrowings under the Amended
Agreements will be used for working capital and other corporate purposes,
including commercial paper backup.

3. CAPITALIZATION

PREFERRED STOCK

   At March 31, 1995 and December 31, 1994, the Company had 17,000,000 shares of
preferred stock authorized by its articles of incorporation of which 11,889,553
and 12,787,228 shares were issued and outstanding, respectively.

   The Company redeemed or purchased 897,675 shares of preferred stock with
annual dividend rates ranging from $7.22 to $10.375 during the three months
ended March 31, 1995.

   On May 1, 1995, the Company redeemed 125,000 shares of $9.64 Cumulative
Preferred Stock which fulfills its mandatory redemption requirement until
November 1, 1995.

LONG-TERM DEBT

   During the three months ended March 31, 1995, the Company borrowed
$300,000,000 pursuant to a term credit agreement (Credit Agreement), which
matures on February 28, 1997.  The Credit Agreement permits the Company to
select between two methods of calculating a variable interest rate.  At March
31, 1995 the rate was 6.55% for a one-month period.

   The Company purchased and retired $25,100,000 aggregate principal amount of 
9-7/8% First Mortgage and Collateral Trust Bonds due November 1, 2019 during the
three months ended March 31, 1995, and redeemed the remaining $86,050,000 of
such series in April 1995.

   In April 1995, the Brazos River Authority and the Sabine River Authority of 
Texas issued $66,670,000 aggregate principal amount of Pollution Control Revenue
Bonds collateralized by an equal amount of the Company's First Mortgage and 
Collateral Trust Bonds.  Such bonds are currently in a flexible mode and 
secured by an irrevocable letter of credit.  Also in April 1995, an aggregate 
principal amount of $9,000,000 of the Brazos River Authority Pollution Control 
Revenue Bonds, Taxable Series 1991 was defeased.

4. RETAINED EARNINGS

   The articles of incorporation and the mortgage, as supplemented, of the
Company contain provisions which, under certain conditions, restrict
distributions on or acquisitions of its common stock.  At March 31, 1995,
$139,278,000 of retained earnings were thus restricted as a result of such
provisions.

   The articles of incorporation restriction provides, in effect, that the
Company shall not pay any common dividend which would reduce retained earnings
to less than one and one-half times annual preferred dividend requirements.  The
mortgage restriction provides that the Company shall not pay any common
dividend, other than dividends payable solely in shares of its common stock, out
of reserved and restricted retained earnings of the Company and shall not make
any such declaration or payment when the Company is insolvent, or when the
payment thereof would render the Company insolvent.

6. RATE PROCEEDINGS

DOCKET 11735

   In July 1994, the Company filed a petition in the 200th Judicial District
Court of Travis County, Texas to seek judicial review of the final order of the
Public Utility Commission of Texas (PUC) granting a $449 million, or 9.0% rate
increase in connection with the Company's January 1993 rate increase request of
$760 million, or 15.3% (Docket 11735).  Other parties to the PUC proceedings
also filed appeals with respect to various portions of the order.  The Company
is unable to predict the outcome of such appeals.

DOCKET 9300

   The PUC's final order (Order) in connection with the Company's January 1990
rate increase request (Docket 9300) has been reviewed by the 250th Judicial
District Court of Travis County, Texas (District Court)  and thereafter was
appealed to the Court of Appeals for the Third District of Texas (Court of
Appeals).  In June 1994, the Court of Appeals affirmed a prudence disallowance
of $472 million provided for in the Order with respect to Comanche Peak nuclear
generating station (Comanche Peak), reversed and remanded the portion of the
District Court's judgment that had affirmed a disallowance of $25 million
relating to the Company's reacquisitions of the minority owner interests in
Comanche Peak nuclear fuel, and affirmed the District Court's remand of the
remainder of the disallowance of $884 million relating to the reacquisitions of
such minority owner interests. Therefore, the Court of Appeals remanded an
aggregate of $909 million of disallowances with respect to the Company's
reacquisitions of minority owner interests in Comanche Peak to the PUC for
reconsideration and ordered that such reconsideration be on the basis of a
prudent investment standard.

6. RATE PROCEEDINGS -- (CONTINUED)

   In addition, the Court of Appeals reversed the District Court's finding that
the PUC erred in ordering a refund of $2.5 million with respect to certain fuel
gas costs.  Also, the Court of Appeals specified that, on remand, the PUC will
be required to re-evaluate the appropriate level of the Company's CWIP included
in rate base in light of its financial condition at the time of the initial
hearing and to reconsider whether the $442 million revenue increase provided for
in the PUC's final order remains the benchmark in light of this re-examination.

   The Court of Appeals also ruled in the appeal of the Company's Docket 9300
rate case that prior court rulings required that the tax benefits generated by
costs, including capital costs, not allowed in rates, must be used to reduce
rates charged to customers, reversing the District Court's decision.  The
Company believes that such ruling is erroneous and not consistent with the Texas
Public Utility Regulatory Act (PURA).  The Company contended that, according to
a Private Letter Ruling issued to the Company by the Internal Revenue Service
(IRS) with respect to investment tax credits, such ratemaking treatment, to the
extent related to property classified for tax purposes as public utility
property, would result in a violation of the normalization rules under the
Internal Revenue Code of 1986, as amended.  Violation of the normalization rules
would result in a significant adverse effect on the Company's results of
operation and liquidity.  If there are normalization violations, the Company
will forfeit its investment tax credits which remain unamortized as of the date
of the violation, and will also forfeit the ability to take advantage of
accelerated tax depreciation in years to which the violative order relates.
This could result in payments to the IRS of up to $1.3 billion. The Company
disagrees with certain portions of the decision of the Court of Appeals,
including specifically its decision with respect to federal income taxes, and
has filed an appeal to the Supreme Court of Texas.  Other parties have also
filed appeals of this decision to the Supreme Court of Texas.  The Company
cannot predict whether such appeals will be accepted by the Supreme Court of
Texas and cannot predict the outcome of any such appeals or any resulting
reconsideration of these issues on remand by the PUC.

   On April 13, 1995 in an appeal of a rate case involving another utility, the
Supreme Court of Texas held that the PUC has considerable discretion in
determining the fair share of consolidated tax savings to be allocated to a
utility and, accordingly, is not required to include losses of unregulated
affiliates in determining such fair share.  The Supreme Court also held that the
PUC could not use the tax benefits generated by disallowed expenses to reduce
rates.

FUEL COST RECOVERY RULE
 
   In August 1994, the Company petitioned the PUC for a recovery of
approximately $93 million, including interest, in under-collected fuel costs for
the period July 1993 through June 1994. The PUC approved the recovery of this
amount over a six-month period beginning in January 1995. The PUC's approval of
this surcharge and a previously approved $147.5 million surcharge for fuel cost
recovery for a prior period have been appealed by certain intervenors to the
district courts of Travis County, Texas. In those appeals, those parties are
contending that the PUC is without authority to allow a fuel cost surcharge
without a hearing and findings that the costs are reasonable and necessary and
that the prices charged to the Company by affiliated suppliers are no higher
than the prices charged by those affiliates to others for the same items or
class of items. The Company will vigorously defend its position in these appeals
but is unable to predict their outcome.

6. RATE PROCEEDINGS -- (CONCLUDED)

FLEXIBLE RATE INITIATIVES

   In June 1994, the Company filed with the PUC and municipalities with original
regulatory jurisdiction a package of four proposed flexible rates.  Two of the
proposed rates would allow for negotiated competitive pricing through reductions
in demand charges to retain existing non-residential retail and wholesale
customers who have viable alternative sources of supply and would otherwise
leave the system.  The remaining two rates are an economic development rider and
an  environmental technology service rider.  The economic development rider
would provide an incentive to attract new businesses and jobs and to encourage
existing customers to expand their facilities within the Company's service area.
The environmental technology service rider would provide an incentive for
qualifying customers to convert to advanced technologies that conserve total
energy or improve the environment.  These new rates have been approved and
implemented in over 160 municipalities with original regulatory jurisdiction,
including the cities of Dallas and Fort Worth, within the Company's service
territory.  Following hearings on the proposed rates, however, the PUC issued an
interim order on the rate package which either rejected or significantly
weakened the proposed flexible rates, rendering them ineffective.  In January
1995, the Company withdrew its package of proposed rates from consideration by
the PUC.  This action does not affect the over 160 municipalities where the
flexible rates are already in effect.  The Sunset Review of PURA by the Texas
legislature in 1995 is expected to include several of the key issues involved in
this case.  Through its involvement at the legislature and the PUC, the Company
will continue to pursue the possibility of offering flexible rates.

INTEGRATED RESOURCE PLAN

   In October 1994, the Company filed an application for approval by the PUC of
its Integrated Resource Plan (IRP) for the ten-year period 1995-2004.  The IRP
includes initiatives that address demand-side management resources, purchased
power, and future generating capacity that includes renewable energy sources.
The Company's IRP includes 288 megawatts (MW) of simple-cycle combustion
turbines, 1,514 MW of combined-cycle combustion turbines and 300 MW of wind or
other renewable resources.  Assuming these units are financed by the Company
using traditional methods, approximately $200 million would be added to capital
expenditures in 1997.  The Company's IRP also includes one lignite-fueled 750 MW
unit at Twin Oak.  The second lignite-fueled Twin Oak unit has been delayed
beyond the ten-year period.  Hearings on this application were concluded in
March 1995.  The PUC's decision on the IRP is expected in mid-1995.

7. COMMITMENTS AND CONTINGENCIES

CAPITAL EXPENDITURES

   Construction expenditures for utility related activities, excluding AFUDC and
expenditures relating to new generating units, are presently estimated at $372
million for each of the years 1995, 1996 and 1997. Expenditures for nuclear fuel
and non-utility property are presently estimated at $46 million for 1995, $53
million for 1996, and $80 million for 1997. Active construction and the accrual
of AFUDC on Twin Oak, suspended in 1987 due to forecast changes in load growth,
would need to resume in 1999 in order to meet the current schedule. Due to the
delay, and the possibility of further delays resulting from forecast changes, in
the schedule of Twin Oak, as well as the lignite-fueled Forest Grove facility
which is not included in the ten-year resource plan, the Company is
contemplating alternative uses for its investment in these projects, which might
include construction as exempt

facilities.  While the Company currently believes that its investment in these
assets can be recovered if held and ultimately developed according to existing
plans, other alternative uses might contribute more to the Company's long-term
strategy of maximizing shareholder value, and might include disposition for
amounts which may be less than current book value with respect to these assets.
Management has no specific plans for alternative uses.  In March 1995, such
investment of approximately $729 million was transferred from CWIP to Electric
Plant Held for Future Use.

   The re-evaluation of growth expectations, the effects of inflation,
additional regulatory requirements and the availability of fuel, labor,
materials and capital may result in changes in estimated construction costs and
dates of completion. Commitments in connection with the construction program are
generally revocable subject to reimbursement to manufacturers for expenditures
incurred or other cancellation penalties.

   The Company plans to seek new investment opportunities from time to time when
it concludes that such investments are consistent with its business strategies
and will likely enhance the long-term returns to its shareholders. The timing
and amounts of any specific new business investment opportunities are presently
undetermined.

CLEAN AIR ACT

   The Company's capital requirements have not been significantly affected by
the requirements of the federal Clean Air Act, as amended (Clean Air Act).
Although the Company is unable to fully determine the cost of compliance with
the Clean Air Act, it is not expected to have a significant impact on the
Company. During 1994, installation of continuous emissions monitoring systems
was completed at a total cost of approximately $38 million. Any additional
capital costs, as well as any increased operating costs, associated with these
new requirements or compliance measures, are expected to be recoverable through
rates, as similar costs have been recovered in the past. The Company's
environmental expenditures for 1995 are estimated to be $58 million.

COOLING WATER CONTRACTS

   The Company has entered into contracts with public agencies to purchase
cooling water for use in the generation of electric energy. In connection with
certain contracts, the Company has agreed, in effect, to guarantee the
principal, $36,650,000 at March 31, 1995, and interest on bonds issued to
finance the reservoirs from which the water is supplied. The bonds mature at
various dates through 2011 and have interest rates ranging from 5-1/2% to 7%.
The Company is required to make periodic payments equal to such principal and
interest including amounts assumed by a third party and reimbursed to the
Company. In addition, the Company is obligated to pay certain variable costs of
operating and maintaining the reservoirs. The Company has assigned to a
municipality all contract rights and obligations of the Company in connection
with $84,610,000 remaining principal amount of bonds at March 31, 1995, issued
for similar purposes which had previously been guaranteed by the Company. The
Company is, however, contingently liable in the unlikely event of default by the
municipality.

NUCLEAR INSURANCE

   With regard to liability coverage, the Price-Anderson Act (Act) provides
financial protection for the public in the event of a significant nuclear power
plant incident. The Act sets the statutory limit of public liability for a
single nuclear incident currently at $8.9 billion and requires nuclear power
plant operators to provide financial protection for this amount. As required,
the Company provides this financial protection for a nuclear incident at
Comanche Peak resulting in public bodily injury and property damage through a
combination of private insurance and industry-wide retrospective payment plans.
As the first layer of financial protection, the Company has purchased $200
million of liability insurance from American Nuclear Insurers (ANI), which
provides such insurance on behalf of two major stock and mutual insurance pools,
Nuclear Energy Liability Insurance Association and Mutual Atomic Energy
Liability Underwriters. The second layer of financial protection is provided
under an industry-wide retrospective payment program called Secondary Financial
Protection (SFP). Under the SFP, each operating licensed reactor in the United
States is subject to an assessment of up to $79.275 million, subject to
increases for inflation every five years, in the event of a nuclear incident at
any nuclear plant in the United States. Assessments are limited to $10 million
per operating licensed reactor per year per incident. All assessments under the
SFP are subject to a 3% insurance premium tax which is not included in the
amounts above.

   With respect to nuclear decontamination and property damage insurance,
Nuclear Regulatory Commission (NRC) regulations require that nuclear plant
license-holders maintain not less than $1.06 billion of such insurance and
require the proceeds thereof to be used to place a plant in a safe and stable
condition, to decontaminate it pursuant to a plan submitted to and approved by
the NRC before the proceeds can be used for plant repair or restoration or to
provide for premature decommissioning. The Company maintains nuclear
decontamination and property damage insurance for Comanche Peak in the amount of
$3.6 billion, above which the Company is self-insured. The primary layer of
coverage of $500 million is provided by ANI. The remaining coverage includes
premature decommissioning coverage and is provided by ANI in the amount of $850
million and Nuclear Electric Insurance Limited (NEIL), a nuclear electric
utility industry mutual insurance company, in the amount of $2.25 billion. The
Company is subject to a maximum annual assessment from NEIL of $30 million in
the event NEIL's losses under this type of insurance for major incidents at
nuclear plants participating in this program exceed its accumulated funds and
reinsurance.

   The Company maintains Extra Expense Insurance through NEIL to cover the
additional costs of obtaining replacement power from another source if one or
both of the units at Comanche Peak are out of service for more than twenty-one
weeks as a result of covered direct physical damage.  The coverage provides for
weekly payments of $3.5 million for the first and $2.8 million for the second
and third fifty-two week periods of each outage, respectively, after the initial
twenty-one week period.  The total maximum coverage is $473 million per unit.
The coverage amounts applicable to each unit will be reduced to 80% if both
units are out of service at the same time as a result of the same accident.
Under this coverage, the Company is subject to a maximum assessment of $10
million per year.

NUCLEAR DECOMMISSIONING AND DISPOSAL OF SPENT FUEL

   The Company has established a reserve, charged to depreciation expense and
accumulated depreciation, for the decommissioning of Comanche Peak, whereby
decommissioning costs are being recovered from customers over the life of the
plant and deposited in external trust funds (included in other investments). At
March 31, 1995, such reserve totaled $60,646,000 which includes an accrual of
$4,545,000 and $18,179,000 for the three and twelve months ended March 31, 1995,
respectively. As of March 31, 1995, the market value of deposits in the external
trust for decommissioning of Comanche Peak was $62,698,000. Realized earnings on
funds deposited in the external trust are recognized in the reserve. Based on a
site-specific study during 1992 using the prompt dismantlement method and then-
current dollars, decommissioning costs for Comanche Peak Unit 1, and Unit 2 and
common facilities were estimated to be $255,000,000 and $344,000,000,
respectively. Decommissioning activities are projected to begin in 2030 and 2032
for Comanche Peak Unit 1, and Unit 2 and common facilities, respectively. The
Company is recovering such costs based upon the 1992 study through its rates
placed in effect under Docket 11735. (See Note 6.)

   The Company has a contract with the United States Department of Energy for
the future disposal of spent nuclear fuel at a cost of one mill per kilowatt-
hour of Comanche Peak net generation. The disposal fee is included in nuclear
fuel expense.

GENERAL

   In addition to the above, the Company is involved in various legal and
administrative proceedings which, in the opinion of the Company, should not have
a material effect upon its financial position or results of operation.

8. ACCOUNTING CHANGE

   In March 1995, Statement of Financial Accounting Standards No. 121,
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to
Be Disposed Of" (Statement 121) was issued.  Statement 121 is effective for
financial statements for fiscal years beginning after December 15, 1995 and
prescribes a methodology for assessing and measuring impairments in the carrying
value of certain assets.  As a result of such standard, the Company will be
subject to a more formal standard for assessing asset impairment in the future.

INDEPENDENT ACCOUNTANTS' REPORT
Texas Utilities Electric Company:

We have reviewed the accompanying condensed balance sheet of Texas Utilities
Electric Company as of March 31, 1995, and the related condensed statements of
income and of cash flows for the three-month and twelve-month periods ended
March 31, 1995 and 1994.  These financial statements are the responsibility of
the Company's management.

We conducted our review in accordance with standards established by the American
Institute of Certified Public Accountants.  A review of interim financial
information consists principally of applying analytical procedures to financial
data and making inquiries of persons responsible for financial and accounting
matters.  It is substantially less in scope than an audit in accordance with
generally accepted auditing standards, the objective of which is the expression
of an opinion regarding the financial statements taken as a whole.  Accordingly,
we do not express such an opinion.

Based on our review, we are not aware of any material modifications that should
be made to such condensed financial statements for them to be in conformity with
generally accepted accounting principles.

We have previously audited, in accordance with generally accepted auditing
standards, the balance sheet of Texas Utilities Electric Company as of December
31, 1994, and the related statements of income, retained earnings and cash flows
for the year then ended (not presented herein); and in our report dated March 1,
1995, we expressed an unqualified opinion on those financial statements, which
opinion included an explanatory paragraph concerning the Company's changes in
accounting for income taxes, postretirement benefits other than pensions and in
accounting for base rate revenue sold but not billed.  In our opinion, the
information set forth in the accompanying condensed balance sheet as of December
31, 1994, is fairly stated in all material respects in relation to the balance
sheet from which it has been derived.

LIQUIDITY AND CAPITAL RESOURCES

   For information concerning liquidity and capital resources, see Item 7.
Management's Discussion and Analysis of Financial Condition and Results of
Operation in the Texas Utilities Electric Company (Company) Form 10-K for the
year 1994.  No significant changes or events which might affect the financial
condition of the Company have occurred subsequent to year-end other than as
disclosed in this report.

   External funds of a permanent or long-term nature are obtained through sales
of common stock to Texas Utilities Company (Texas Utilities), and of preferred
stock and long-term debt.  The capitalization ratios of the Company at March 31,
1995 consisted of approximately 51% long-term debt, 8% preferred stock and 41%
common stock equity.

   The Company had financings totaling $366,670,000 to date in 1995.  Proceeds
from such financings were used primarily for the early redemption or
reacquisition of debt and preferred stock.  Financings to date in 1995 by the
Company consisted of:

   To date in 1995, the Company redeemed, purchased and retired, defeased or
made principal payments of $242,841,000 on long-term debt and preferred stock.
Early redemptions of long-term debt and preferred stock may occur from time to
time in amounts presently undetermined.

   The Company expects to sell additional debt and equity securities as needed
including (i) the possible future sale by the Company of up to $650,000,000 of
First Mortgage Bonds currently registered with the Securities and Exchange
Commission for offering pursuant to Rule 415 under the Securities Act of 1933
and (ii) the possible future sale by the Company of 250,000 shares of Cumulative
Preferred Stock ($100 liquidation value) similarly registered.

   On April 28, 1995, the Company and Texas Utilities renegotiated their credit
facility agreements and entered into amendments that extended the terms of such
credit facility agreements (Amended Agreements).  The Amended Agreements have
two facilities, for each of which Texas Utilities pays a fee.  Facility A
provides for borrowings up to $300,000,000 and terminates April 28, 1996.
Facility B provides for borrowings up to $700,000,000 and terminates April 28,
2000. Borrowings under the Amended Agreements will be used for working capital
and other corporate purposes, including commercial paper backup.

   In order to remain competitive, the Company is aggressively managing its
operating costs and capital expenditures through streamlined business processes
and is developing and implementing strategies to address an increasingly
competitive environment.  These strategies include initiatives to improve the
Company's return on corporate assets and to maximize shareholder value through
new marketing programs, creative rate design, and new business opportunities.
Additional initiatives under consideration include the potential disposition or
alternative utilization of existing assets and the restructuring of strategic
business units.  Some of the Company's

LIQUIDITY AND CAPITAL RESOURCES -- (CONTINUED)

assets, including approximately $729 million invested in partially completed
generating facilities on which construction is temporarily suspended, are not
contributing to earnings and, as a result, the Company is considering possible
alternatives to the scheduled development, operation and recovery of such assets
through traditional means. While the Company currently believes that its
investment in these assets can be recovered if held and ultimately developed
according to existing plans, other alternatives might contribute more to the
Company's long-term strategy for maximizing shareholder value and might include
disposition for amounts which may be less than current book value with respect
to these assets. It is not possible at this time to predict the effect any of
these possible initiatives might have on the carrying value of the Company's
assets or its results of operation.

   In July 1994, the Company filed a petition in the 200th Judicial District
Court of Travis County, Texas to seek judicial review of the final order of the
Public Utility Commission of Texas (PUC) granting a $449 million, or 9.0%, rate
increase in connection with the Company's  January 1993 rate increase request of
$760 million, or 15.3% (Docket 11735).  Other parties to the PUC proceedings
also filed appeals with respect to various portions of the order.  The Company
is unable to predict the outcome of such appeals.

   The PUC's final order (Order) in connection with the Company's January 1990
rate increase request (Docket 9300) has been reviewed by the 250th Judicial
District Court of Travis County, Texas (District Court)  and thereafter was
appealed to the Court of Appeals for the Third District of Texas (Court of
Appeals).  In June 1994, the Court of Appeals affirmed a prudence disallowance
of $472 million provided for in the Order with respect to its Comanche Peak
nuclear generating station (Comanche Peak), reversed and remanded the portion of
the District Court's judgment that had affirmed a disallowance of $25 million
relating to the Company's reacquisitions of the minority owner interests in
Comanche Peak nuclear fuel, and affirmed the District Court's remand of the
remainder of the disallowance of $884 million relating to the reacquisitions of
such minority owner interests.  Therefore, the Court of Appeals remanded an
aggregate of  $909 million of  disallowances with respect to the Company's
reacquisitions of minority owner interests in Comanche Peak to the PUC for
reconsideration and ordered that such reconsideration be on the basis of a
prudent investment standard.

   In addition, the Court of Appeals reversed the District Court's finding that
the PUC erred in ordering a refund of $2.5 million with respect to certain fuel
gas costs.  Also, the Court of Appeals specified that, on remand, the PUC will
be required to re-evaluate the appropriate level of the Company's construction
work in progress included in rate base in light of its financial condition at
the time of the initial hearing and to reconsider whether the $442 million
revenue increase provided for in the PUC's final order remains the benchmark in
light of this re-examination.

   The Court of Appeals also ruled in the appeal of the Company's Docket 9300
rate case that prior court rulings required that the tax benefits generated by
costs, including capital costs, not allowed in rates, must be used to reduce
rates charged to customers, reversing the District Court's decision.  The
Company believes that such ruling is erroneous and not consistent with the Texas
Public Utility Regulatory Act (PURA).  The Company contended that, according to
a Private Letter Ruling issued to the Company by the Internal Revenue Service
(IRS) with respect to investment tax credits, such ratemaking treatment, to the
extent related to property classified for tax purposes as public utility
property, would result in a violation of the normalization rules under the
Internal Revenue Code of 1986, as amended.  Violation of the normalization rules
would result in a significant adverse effect on the Company's results of
operation and liquidity.  If there are normalization violations, the Company
will forfeit its investment tax credits which remain unamortized as of the date
of the violation, and will also forfeit the ability to take advantage of
accelerated tax depreciation in years to which the violative order relates.
This could result in payments to the IRS of up to $1.3 billion.  The Company
disagrees with certain portions of the decision of the Court of Appeals,
including specifically its decision with respect to federal income taxes, and
has filed an appeal to the Supreme Court of Texas.  Other parties have also
filed appeals of this decision to the Supreme Court of Texas.  The

LIQUIDITY AND CAPITAL RESOURCES -- (CONTINUED)

Company cannot predict whether such appeals will be accepted by the Supreme
Court of Texas and cannot predict the outcome of any such appeals or any
resulting reconsideration of these issues on remand by the PUC.

   On April 13, 1995 in an appeal of a rate case involving another utility, the
Supreme Court of Texas held that the PUC has considerable discretion in
determining the fair share of consolidated tax savings to be allocated to a
utility and, accordingly, is not required to include losses of unregulated
affiliates in determining such fair share.  The Supreme Court also held that the
PUC could not use the tax benefits generated by disallowed expenses to reduce
rates.
 
   In August 1994, the Company petitioned the PUC for a recovery of
approximately $93 million, including interest, in under-collected fuel costs for
the period July 1993 through June 1994. The PUC approved the recovery of this
amount over a six-month period beginning in January 1995. The PUC's approval of
this surcharge and a previously approved $147.5 million surcharge for fuel cost
recovery for a prior period have been appealed by certain intervenors to the
district courts of Travis County, Texas. In those appeals, those parties are
contending that the PUC is without authority to allow a fuel cost surcharge
without a hearing and findings that the costs are reasonable and necessary and
that the prices charged to the Company by affiliated suppliers are no higher
than the prices charged by those affiliates to others for the same item or class
of items. The Company will vigorously defend its position in these appeals but
is unable to predict their outcome.

   In June 1994, the Company filed with the PUC and its municipalities with
original regulatory jurisdiction a package of four proposed flexible rates. Two
of the proposed rates would allow for negotiated competitive pricing through
reductions in demand charges to retain existing non-residential retail and
wholesale customers who have viable alternative sources of supply and would
otherwise leave the system. The remaining two rates are an economic development
rider and an environmental technology service rider. The economic development
rider would provide an incentive to attract new businesses and jobs and to
encourage existing customers to expand their facilities within the Company's
service area. The environmental technology service rider would provide an
incentive for qualifying customers to convert to advanced technologies that
conserve total energy or improve the environment. These new rates have been
approved and implemented in over 160 municipalities with original regulatory
jurisdiction, including the cities of Dallas and Ft. Worth, within the Company's
service territory. Following hearings on the proposed rates, however, the PUC
issued an interim order on the rate package which either rejected or
significantly weakened the proposed flexible rates, rendering them ineffective.
In January 1995, the Company withdrew its package of proposed rates from
consideration by the PUC. This action does not affect the over 160
municipalities where the flexible rates are already in effect. The Sunset Review
of PURA by the Texas legislature in 1995 is expected to include several of the
key issues involved in this case. Through its involvement at the legislature and
the PUC, the Company will continue to pursue the possibility of offering
flexible rates.

   In October 1994, the Company filed an application for approval by the PUC of
its Integrated Resource Plan (IRP) for the ten year period 1995-2004. The IRP
includes initiatives that address demand-side management resources, purchased
power, and future generating capacity that includes renewable energy sources.
The Company's IRP includes 288 megawatts (MW) of simple-cycle combustion
turbines, 1,514 MW of combined-cycle combustion turbines and 300 MW of wind or
other renewable resources. Assuming these units are financed by TU Electric
using traditional methods, approximately $200 million would be added to capital
expenditures in 1997. The Company's IRP also includes one lignite-fueled 750 MW
unit at Twin Oak. The second lignite-fueled Twin Oak unit has been deferred
beyond the ten-year planning period. Hearings on this application were concluded
in March 1995. The PUC's decision on the IRP is expected in mid-1995.

LIQUIDITY AND CAPITAL RESOURCES -- (CONCLUDED)

   The Company's capital requirements have not been significantly affected by
the requirements of the federal Clean Air Act, as amended (Clean Air Act).
Although the Company is unable to fully determine the cost of compliance with
the Clean Air Act, it is not expected to have a significant impact on the
Company. During 1994, installation of continuous emissions monitoring systems
was completed at a total cost of approximately $38 million. Any additional
required capital costs, as well as any increased operating costs, associated
with these new requirements or compliance measures are expected to be
recoverable through rates, as similar costs have been recovered in the past. The
Company's environmental expenditures for 1995 are estimated to be $58 million.

   The National Energy Policy Act of 1992 (Energy Act) addresses a wide range of
energy issues and is intended to increase competition in electric generation and
broaden access to electric transmission systems.  The PUC has initiated a
generic rule making proceeding to address transmission issues within Texas.  In
addition, legislation is currently being considered by the Texas legislature
which, if enacted, could impact the structure of the PUC and its regulatory
practices and could lead to increased competition in some aspects of the
electric utility industry.  Although the Company is unable to predict the
ultimate impact of the Energy Act and any related regulations or any potential
state legislation or PUC regulation on its operations, it believes that such
actions are consistent with the trend toward increased competition in the energy
industry.

   While the Company has experienced competitive pressures in the wholesale
market resulting in approximately 379 MW loss of load since the beginning of
1993, wholesale sales represented a relatively low percentage of total operating
revenues in 1994. The Company is unable to predict the extent of future
competitive developments in either the wholesale or retail markets or what
impact, if any, such developments may have on its operations.

RESULTS OF OPERATION

   The following compares operating results for the three- and twelve-month
periods ended March 31, 1995 with the same periods ended March 31, 1994.

   Operating revenues decreased approximately 4% and less than 1% for
the three- and twelve-month periods ended March 31, 1995, respectively. The
following table details the factors contributing to these changes:

Base rate revenue decreased for the three-month period and increased for the
twelve-month period.    Energy sales decreased approximately 2% and increased
approximately 1% for the three- and twelve-month periods, respectively.  The
effect on energy sales and base rate revenue for both periods was primarily a
result of mild weather conditions and loss of wholesale power sales, partially
offset by an increase in customers and billing cycle days.  For the twelve-month
period, the rate increase placed in effect in August 1993 increased base rate
revenues over the prior period.  The decrease in fuel revenue for both periods
was primarily due to a reduction in gas prices and, for the twelve-month period,
increased nuclear generation as compared to the prior period.  The decrease in
unbilled revenue and other in both periods resulted from milder weather
conditions than the prior period and an increase in the number of billing days.

        OF OPERATION (CONTINUED)

RESULTS OF OPERATION -- (CONCLUDED)

   Fuel and purchased power expense decreased approximately 6% and 9% for the
three-and twelve-month periods, respectively,primarily due to a reduction in gas
prices, purchased power commitments and, for the twelve-month period, increased
utilization of nuclear fuel.

   Total operating expenses, excluding fuel and purchased power, decreased
approximately 4% and increased approximately 2% for the three- and twelve-month
periods, respectively. Combined operation and maintenance expense decreased for
both periods due primarily to a decrease in employee benefit expenses and, for
the twelve-month period, a reduction in inventory adjustments taken in the prior
period. For the twelve-month period, such decrease was partially offset by the
effect of the commencement of commercial operation of Unit 2 of Comanche Peak
and the amortization of voluntary retirement/severance costs. Taxes other than
income decreased for the three-month period due primarily to a reduction in
franchise, state gross receipts and estimated ad valorem taxes. The increase in
the twelve-month period was due to increased local gross receipts taxes
resulting from higher tax rates and increased gross receipts revenues partially
offset by a reduction in estimated ad valorem taxes.

   Allowance for funds used during construction (AFUDC) decreased 5% and 87% for
the three- and twelve-month periods, respectively. The decrease in the twelve-
month period was primarily due to the discontinuation of the accrual of AFUDC on
Unit 2 of Comanche Peak when such unit achieved commercial operation in August
1993.
 
   The regulatory disallowance in the prior twelve-month period reflects charges
resulting from a settlement agreement among the parties in Docket 11735.

   Federal income taxes -- other income increased for the twelve-month period
primarily due to the effect from the prior period of recording the taxes
associated with the regulatory disallowances on Unit 2 of Comanche Peak.
  
   Total interest charges, excluding AFUDC, decreased approximately 6% and 5%
for the three- and twelve-month periods, respectively. Interest on mortgage
bonds decreased over the prior periods as a result of reduced interest
requirements due to the Company's refinancing efforts, partially offset by
increased interest requirements for new issues sold. Interest on other long-term
debt reflects the continuing retirement of debt incurred on the purchases of the
minority ownership interests in Comanche Peak. Other interest expense increased
in both periods due to increased average short-term borrowings and increased
amortization of debt issuance expenses and redemption premiums.

   The major factors affecting net income for the twelve-month period were the
implementation of the rate increase offset by the discontinuation of AFUDC on
Comanche Peak Unit 2 and the commencement of depreciation on approximately $668
million of investment in Comanche Peak Unit 2 incurred after the end of the
Docket 11735 test year which is not being recovered currently in rates. The
major factors affecting net income for the three-month period were continuing
cost reduction efforts partially offset by mild weather conditions. Net income
before preferred dividends increased approximately 3% and 60% for the three- and
twelve-month periods, respectively.

   Preferred stock dividends decreased approximately 16% and 14% for the three-
and twelve-month periods, respectively, primarily due to the redemption of
certain series with higher dividend rates.

ACCOUNTING CHANGE

   In March 1995, Statement of Financial Accounting Standards No. 121,
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to
Be Disposed Of" (Statement 121) was issued. Statement 121 is effective for
financial statements for fiscal years beginning after December 15, 1995 and
prescribes a methodology for assessing and measuring impairments in the carrying
value of certain assets. As a result of such standard, the Company will be
subject to a more formal standard for assessing asset impairment in the future.

     SECTION 1. There shall be a series of bonds designated "Pollution Control

debts. Bonds of the Seventy-ninth Series shall be dated as in Section 2.03 of
the Original Indenture provided.

     (I)  The bonds of the Seventy-ninth Series shall be initially issued in the

fixed for redemption. Notwithstanding the provisions of Section 12.02 of the
Mortgage, any such notice under such subsection shall not be conditional.
