                     NOTES TO CONDENSED FINANCIAL STATEMENTS
                             MARCH 31, 1999 AND 1998


(A)     The condensed financial statements included herein have been prepared by
        Oglethorpe Power Corporation (Oglethorpe), without audit, pursuant to
        the rules and regulations of the Securities and Exchange Commission
        (SEC). In the opinion of management, the information furnished herein
        reflects all adjustments (which include only normal recurring
        adjustments) and estimates necessary to present fairly, in all material
        respects, the results for the periods ended March 31, 1999 and 1998.
        Certain information and footnote disclosures normally included in
        financial statements prepared in accordance with generally accepted
        accounting principles have been condensed or omitted pursuant to such
        SEC rules and regulations, although Oglethorpe believes that the
        disclosures are adequate to make the information presented not
        misleading. It is suggested that these condensed financial statements be
        read in conjunction with the financial statements and the notes thereto
        included in Oglethorpe's latest Annual Report on Form 10-K, as filed
        with the SEC. Certain amounts for 1998 have been reclassified to conform
        with the current period presentation.

(B)     In June 1998, the Financial Accounting Standards Board issued Statement
        of Financial Accounting Standards (SFAS) No. 133, "Accounting for
        Derivative Instruments and Hedging Activities." The standard requires
        that all derivative instruments be recognized as assets or liabilities
        and be measured at fair value. Oglethorpe is required to adopt SFAS No.
        133 by January 1, 2000. Oglethorpe is currently assessing the impact
        that adoption of SFAS No. 133 will have on results of operations and
        financial condition and is undecided as to the date the standard will be
        adopted.

ITEM 2.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
          RESULTS OF OPERATIONS


GENERAL

FUTURE POWER RESOURCES

Under the Wholesale Power Contracts, Oglethorpe's 39 retail electric 
distribution cooperative members (the Members) may choose to supply all or a 
portion of their future requirements with purchases from suppliers other than 
Oglethorpe. A new entity, Smarr EMC, was formed in 1998 by 36 of the Members 
to own a two-unit, 217 megawatt (MW) combustion turbine (CT) facility (CT 
One). Commercial operation of this facility is scheduled for June 1999. 
Construction and operation management services, as well as construction 
financing, are currently being provided by Oglethorpe.

Smarr EMC, or similar entities, may also own future generation facilities on
behalf of Members who may decide to participate in such projects. One such
project is a four-unit, 492 MW CT facility (CT Two) currently under
consideration by the Members, which is scheduled for commercial operation by the
summer of 2000. Oglethorpe is providing construction management services and
interim financing for this facility and anticipates that it will provide
operation management services as well.

In addition, two Members have formed an entity which is constructing 90 MW of CT
capacity for commercial operation by the summer of 1999.

All of these CTs are currently anticipated to be dispatched in the Oglethorpe
pool of generation resources.


POWER PURCHASES FROM GPC

Oglethorpe has entered into an agreement with Georgia Power Company (GPC)
effective April 1, 1999 to purchase capacity and associated energy on a
take-or-pay basis. Under the agreement, Oglethorpe has committed to purchase 250
MW of capacity and associated energy through March 31, 2006 and an additional
250 MW for a one-year period beginning June 1, 1999. In addition to these
amounts, Oglethorpe may elect, prior to May 26, 1999, to purchase up to 250 MW
through March 31, 2003. If Oglethorpe does not make the election, it will
purchase the additional 250 MW through August 31, 2000, will reduce this amount
to 125 MW from September 1, 2000 to August 31, 2001, and will not purchase any
additional amount after August 31, 2001. Upon the effectiveness of this
agreement, the Block Power Sale Agreement (BPSA) between Oglethorpe and GPC was
terminated. The BPSA had provided for Oglethorpe to purchase 500 MW of capacity
and associated energy through December 31, 2003. Unlike under the BPSA,
Oglethorpe has no right (other than as described above) to reduce its purchase
obligations under the new agreement prior to its expiration.

RESULTS OF OPERATIONS

FOR THE THREE MONTHS ENDED MARCH 31, 1999 AND 1998

OPERATING REVENUES

Revenues from sales to Members for the three months ended March 31, 1999 were 
5.6% higher than the same period of 1998 and megawatt-hour (MWh) sales to 
Members were 11.8% higher for the current period. This resulted in a 5.5% 
decrease in the average revenue per MWh from sales to Members for the current 
period compared to the same period of 1998. The components of Member revenues 
for the three months ended March 31, 1999 and 1998 were as follows:

                           --------          --------

</TABLE>

While capacity revenues from Members for the three months ended March 31, 1999
compared to 1998 were virtually unchanged, energy revenues were 18.0% higher for
the current quarter compared to the same period of 1998. The higher MWh sales to
Members discussed above were primarily due to continued sales growth in the
Members' service territories. In addition, Oglethorpe provided the Members with
additional energy to offset lower delivery of hydroelectric power from
Southeastern Power Administration (SEPA) due to lower than normal rainfall.
Oglethorpe's average energy revenue per MWh from sales to Members for the
three-month period was 5.6% higher in 1999 compared to 1998. This increase
resulted primarily from higher purchased power energy costs as discussed below
under "OPERATING EXPENSES."

Sales to non-Members were primarily from energy sales to other utilities and
power marketers. The following table summarizes the amounts of non-Member
revenues from these sources for the three months ended March 31, 1999 and 1998:

Sales to other utilities       $3,826       $2,225
Sales to power marketers        1,895        1,099
                               ------       ------
     Total                     $5,721       $3,324
                               ------       ------
                               ------       ------

</TABLE>

Sales to other utilities represent sales made directly by Oglethorpe. Oglethorpe
sells for its own account any energy available from the portion of its resources
dedicated to Morgan Stanley Capital Group Inc. (Morgan Stanley) that is not
scheduled by Morgan Stanley pursuant to its power marketer


                                       9
<PAGE>

arrangement. Sales to other utilities were higher for the three-month period of
1999 compared to 1998 primarily due to capacity revenues received under an
agreement entered into with Alabama Electric Cooperative to sell 100 MW of
capacity for the period June 1998 through December 2005.

Under the LG&E Energy Marketing Inc. (LEM) and Morgan Stanley power marketer
arrangements, sales to the power marketers represented the net energy
transmitted on behalf of LEM and Morgan Stanley off-system on a daily basis from
Oglethorpe's total resources. Such energy was sold to LEM at Oglethorpe's cost,
subject to certain limitations, and to Morgan Stanley at a contractually fixed
price. The volume of sales to power marketers depends primarily on the power
marketers' decisions for servicing their load requirements.


OPERATING EXPENSES

Operating expenses for the three months ended March 31, 1999 were 9.3% higher 
compared to the same period of 1998. This increase was primarily due to 15.5% 
higher total purchased power costs for the current quarter compared to the 
same quarter of 1998. Oglethorpe purchased 22.3% more MWhs in the three 
months ended March 31, 1999 than in the same period of 1998. This resulted in 
a decrease of 5.6% in the average cost per MWh of total purchased power. The 
higher volume of purchased MWhs relates primarily to the portion of increased 
Member load not contractually provided by the power marketers. Purchased 
power costs are as follows:

Capacity costs          $25,408           $30,174  
Energy costs             37,598            24,390
                        -------          --------
     Total              $63,006           $54,564

                        -------          --------

</TABLE>

Purchased power capacity cost for the three months ended March 31, 1999 was
15.8% lower than the same period of 1998. These savings were primarily a result
of the elimination, effective September 1, 1998, of a 250 MW component block
under the BPSA between Oglethorpe and GPC. Purchased power energy costs for 
the three-month period of 1999 were 54.2% higher compared to the same period 
of 1998 as a result of higher volumes of purchased MWhs and higher prices 
experienced in the wholesale electricity markets. These factors resulted in a 
26.0% increase in the average cost of purchased power energy per MWh for the 
three-month period compared to 1998. This increase in the average cost of 
purchased power energy was primarily responsible for an increase in the 
average MWh cost of energy to the Members.

NET MARGIN AND COMPREHENSIVE MARGIN

Oglethorpe's net margin for the three months ended March 31, 1999 was $8.1
million compared to $7.6 million for the same period of 1998. Comprehensive
margin for Oglethorpe is net margin adjusted for the net change in unrealized
gains and losses on investments in available-for-sale securities.


                                       10
<PAGE>

FINANCIAL CONDITION

Total assets and total equity plus liabilities as of March 31, 1999 were $4.5
billion, which was $20 million more than the total at December 31, 1998 due
primarily to an increase in notes and interim financing receivable for
construction of CT One and CT Two, offset by depreciation of plant. These CT
projects are being financed on an interim basis by Oglethorpe through the
issuance of commercial paper. Oglethorpe expects to be reimbursed for the costs
relating to the construction of these projects at the time each facility becomes
commercially operable, which Oglethorpe anticipates will be June 1999 for CT One
and the summer of 2000 for CT Two. For a further discussion of these projects,
see "General--FUTURE POWER RESOURCES."

ASSETS

Property additions for the three months ended March 31, 1999 totaled $16.7
million primarily for purchases of nuclear fuel and for additions, replacements
and improvements to existing generation facilities.

The decrease in cash is a result of cash used in financing and investing
activities, including property additions noted above and debt principal
repayments, exceeding cash provided from operations.

The increase in notes and interim financing receivable resulted primarily from
use of funds in the interim financing activities related to the CT units being
constructed. Included in notes and interim financing receivable as of March 31,
1999 is $54.4 million relating to the construction of CT One and $38.9 million
relating to the construction of CT Two.

Prepayments and other current assets increased primarily due to the estimated
payments to GPC for Plant Hatch operations and maintenance (O&M) costs for April
1999 compared to the estimate for January 1999. The increase in O&M is related
to nuclear fuel purchases and costs to increase the actual and licensed thermal
output of Hatch Units No. 1 and No. 2. The increase in other deferred charges is
related to 1999 refueling outages for Vogtle Unit No.1 and Hatch Unit No.1. Such
costs will be amortized to expense over the 18-month operating cycle of each
unit.

EQUITY AND LIABILITIES

Notes payable represent commercial paper issued by Oglethorpe as interim
financing for costs incurred in construction of CT One and CT Two. Oglethorpe
will be reimbursed by the respective projects' owners for all construction costs
incurred prior to transfer of ownership, and accordingly, has recorded all
expenditures as a receivable. As of March 31, 1999, notes payable consisted of
$52.2 million relating to the financing of CT One and $38.7 million relating to
the financing of CT Two.

Accounts payable increased due primarily to the Hatch Unit No. 1 refueling
outage. This outage resulted in higher than normal charges for nuclear fuel and
O&M.

Accrued interest increased as a result of the accrual for the July 1 interest
payment due for the Scherer Unit No. 2 lease obligation.


                                       11
<PAGE>

Accrued and withheld taxes increased as a result of the normal monthly accruals
for property taxes, which are generally paid in the fourth quarter of the year.


MISCELLANEOUS

COMPETITION

The electric utility industry in the United States is undergoing fundamental
change and is becoming increasingly competitive. This change is promoted by the
Energy Policy Act of 1992, recently adopted and proposed policies from the
Federal Energy Regulatory Commission (FERC) regarding mergers, transmission
access and pricing, federal and state deregulation initiatives, increased
consolidation and mergers of electric utilities, the proliferation of power
marketers and independent power producers, generation surpluses and deficits and
transmission constraints in certain regional markets and other factors.

Several states are in the process of implementing varying forms of "retail 
wheeling" (the transmission of power for a third party directly to a retail 
customer) and most others are in the various stages of considering retail 
competition. Proposed federal legislation could mandate retail wheeling in 
every state and otherwise deregulate the industry. No legislation related to 
retail wheeling has yet been enacted in Georgia, and no bill is currently 
pending in the Georgia legislature which would amend the Georgia Territorial 
Electric Service Act (the Territorial Act) or otherwise affect the exclusive 
right of the Members to supply power to their current service territories. In 
1997, the staff of the Georgia Public Service Commission (GPSC) conducted a 
series of workshops to solicit views from the various parties impacted by 
electric industry restructuring and to discuss potential resolutions of these 
issues, including "stranded costs" which would result from assets having 
unrecovered costs in excess of their economically realizable value. The GPSC 
issued a report identifying electric industry restructuring issues, potential 
resolutions and the views of the parties who participated in the workshops. 
The GPSC's order in the 1998 GPC rate case provides that there will be a 
docket opened to address the mechanics of how stranded costs and stranded 
benefits should be calculated, the estimated range of GPC's stranded costs 
and benefits, the proper level of stranded cost recovery through rate 
surcharges, and the proper disposition of any stranded benefits. The GPSC 
does not have the authority under Georgia law to order retail wheeling or 
amend the Territorial Act. Oglethorpe and the Members participated in the 
GPSC staff workshops and are actively monitoring and studying the GPSC 
proceedings and legislative initiatives in Congress and in other states to 
take advantage of the experiences of cooperatives and other utilities in 
other states to protect their interests in any future legislative activities 
in Georgia.

Under current Georgia law, the Members generally have the exclusive right to
provide retail electric service in their respective territories. Since 1973,
however, the Territorial Act has permitted limited competition among electric
utilities located in Georgia for sales of electricity to certain large
commercial or industrial customers. The owner of any new facility may receive
electric service from the power supplier of its choice if the facility is
located outside of municipal limits and has a connected demand upon initial full
operation of 900 kilowatts or more. The Members, with Oglethorpe's support, are
actively engaged in competition with other retail electric suppliers for these
new commercial and industrial loads. While the competition for 900-kilowatt
loads represents only limited competition in Georgia, this competition has given
Oglethorpe and the Members the opportunity to develop resources and strategies
to operate in an increasingly competitive market.


                                       12
<PAGE>

Oglethorpe cannot predict at this time the outcome of the various developments
that may lead to increased competition in the electric utility industry or the
effect of such developments on Oglethorpe or the Members. Nonetheless,
Oglethorpe has taken several steps to prepare for and adapt to the fundamental
changes that have occurred or are likely to occur in the electric utility
industry. In 1997, Oglethorpe completed the Corporate Restructuring and divided
itself into separate generation, transmission and system operations companies in
order to better serve its Members in a deregulated and competitive environment.
Since 1992, Oglethorpe also has pursued an interest cost reduction program,
which has included refinancings and prepayments of various debt issues, and that
has provided significant cost savings. Oglethorpe has also entered into
arrangements with power marketers to obtain the value that can be brought by
power marketers and to provide for future load requirements without taking all
the risk associated with traditional supply sources. (See Oglethorpe's 1998
Annual report on Form 10-K in "General--Corporate Restructuring", "Financial
Condition--Refinancing Transactions" and "Results of Operations--Power Marketer
Arrangements" in Item 7.)

Oglethorpe and the Members continue to consider and evaluate a wide array of
other potential actions to reduce costs and to enhance their competitiveness in
anticipation of future competition. Oglethorpe regularly considers industry
developments and trends to evaluate the challenges and opportunities they may
present for Oglethorpe. Among the alternatives subject to such consideration by
Oglethorpe are: additional power marketing arrangements or other alliance
arrangements; whether power supply requirements will continue to be met by the
current mix of ownership and purchase arrangements; whether power supply
resources will be owned by Oglethorpe or by separate entities; the effects of
proliferation of services offered by electric utilities; whether disposition of
assets or asset classes would enhance value; the effects of nuclear license
extensions; and other regulatory and business changes that may affect relative
values of generation classes or have impacts on the electric industry. These
activities on the part of Oglethorpe and the Members are in various stages of
study or preliminary consideration. Such studies and consideration necessarily
take account of and are subject to the legal, regulatory and contractual
(including financing and plant co-ownership arrangements) environment applicable
to Oglethorpe.

Many Members are now providing or considering proposals to provide
non-traditional products and services such as telecommunications and other
services. Depending on the nature of future competition in Georgia, there could
be reasons for the Members to separate their physical distribution business from
their energy business, or otherwise restructure their current businesses to
operate effectively under retail competition. Likewise, there could be reasons
for Oglethorpe to evaluate the disposition of generation assets, separating
different segments of its generation assets or business or other restructurings
of its business to operate more effectively under increasing competition.

Recent dispositions of fossil generation units throughout the country are being
evaluated by Oglethorpe, and the recent announcements relating to sales of
nuclear generation units and applications for nuclear license extensions are of
particular interest to Oglethorpe because of its substantial investment in
nuclear generation. These and other developments in the industry have resulted
in the Rural Utilities Service (RUS) exploring the possibility of pursuing 
nationwide measures for RUS and its borrowers that own nuclear generation 
units. This exploration by RUS has included discussions with Oglethorpe and 
others. Oglethorpe intends to pursue its discussions with RUS to determine if

                                       13
<PAGE>

there are feasible measures that Oglethorpe could take to enhance the value of
its assets or further its efforts to lower costs and increase its
competitiveness.

Oglethorpe's ongoing consideration of industry trends and developments may
present opportunities for Oglethorpe to enhance the value of its system or
otherwise to respond more effectively to increasing competition. However,
Oglethorpe cannot predict the results of its evaluation of these matters,
including discussions with RUS, or any action Oglethorpe might take based
thereon.

YEAR 2000

BACKGROUND. The Year 2000 issue, which is common to most corporations, concerns
the ability of certain hardware, software, databases and other devices that use
microprocessors to properly recognize date sensitive information related to the
Year 2000 and thereafter. Oglethorpe is heavily dependent upon complex computer
systems for all phases of power supply operations. Oglethorpe's operations
include both information technology (IT) systems, such as billing systems,
financial accounting systems, and human resource/payroll systems, as well as
non-IT systems that may have embedded microprocessors, such as those relating to
operations of the Rocky Mountain Pumped Storage Hydroelectric Facility (Rocky
Mountain), generation substations and Oglethorpe's headquarters facilities.

Management recognizes the seriousness of the Year 2000 issue and believes it has
dedicated adequate resources to address the issue. Oglethorpe's Senior Vice
President and Chief Financial Officer is in charge of its Year 2000 program, and
he reports directly to Oglethorpe's President and Chief Executive Officer. As
part of its business alliance with Oglethorpe, Intellisource is providing
administration of Oglethorpe's Year 2000 program. Oglethorpe's Board of
Directors and its audit committee are monitoring this issue through periodic
updates from project management.

PROJECT PHASES. Oglethorpe has developed and is implementing a detailed strategy
to prevent any material disruption to operations.

Phase I began in April 1997 and included an inventory and assessment of
potential Year 2000 problems in its systems. Substantially all IT and non-IT
systems have been inventoried and assessed. Oglethorpe has completed an
inventory and assessment on its computer and embedded chip systems at Rocky
Mountain. Critical computer systems required to operate the Rocky Mountain
control room have been upgraded. The computer system required to manage
maintenance activities and purchase materials for Rocky Mountain will be
upgraded by the third quarter of 1999.

Phase II began in the fall of 1997 and includes remediation and testing of all
inventoried IT and non-IT systems. Remediation and testing efforts for all
inventoried internally developed systems applications have been completed.
Oglethorpe is currently in the process of reassessing the completeness of the
original inventory. Financial accounting systems, procurement and materials
management systems and human resource/payroll systems are externally developed
and supported. None of these systems is Year 2000 ready. Oglethorpe is replacing
most of its financial accounting system modules and is retaining and upgrading
one module. Oglethorpe expects its financial accounting systems to be Year 2000
ready by the fourth quarter of 1999. Oglethorpe is replacing its procurement and
materials management systems and expects to complete this remediation in the
second quarter of 1999. Oglethorpe is upgrading its human resource/payroll
systems and expects to complete this remediation in the third quarter of 1999.
Remediation and testing efforts for systems at Rocky Mountain are


                                       14
<PAGE>

expected to be completed by the third quarter of 1999.

Phase III began recently and includes contingency planning, an assessment of
Year 2000 readiness of material third parties and verification that all material
systems were properly inventoried, remediated and tested in Phases I and II.
This phase will be on-going throughout 1999.

RELATIONSHIPS WITH THIRD PARTIES. Georgia Transmission Corporation (GTC) and 
Georgia System Operations Corporation (GSOC) have implemented detailed 
strategies to ensure Year 2000 readiness of the systems utilized in their 
transmission and systems control operations. The Year 2000 readiness plans 
for Oglethorpe, GTC and GSOC were jointly developed and are being implemented 
on the same schedule, as described above.

Oglethorpe has gathered information from the Members regarding their Year 2000
readiness. Based on this information, Oglethorpe will implement a follow-up
program to monitor the Members' Year 2000 readiness and will further assess any
impact on Oglethorpe's risks and contingency planning. Oglethorpe expects to
complete the information gathering process from the Members by September 30,
1999.

All of Oglethorpe's co-owned generating plants, except Rocky Mountain, are
operated by GPC on behalf of itself as a co-owner and as agent for the other
co-owners. Year 2000 remediation and testing on all generation plants which are
operated by GPC are being performed by GPC's parent company, Southern Company
(Southern). Southern estimates that total costs related to this project at the
GPC-operated plants will be approximately $38 million, of which approximately
$4.5 million is expected to be billed to Oglethorpe based on its ownership share
of these generation plants. To date, Oglethorpe has paid approximately $3.8
million for this project. Remaining costs will be expensed primarily in 1999.
Southern reports that its Year 2000 program for the Georgia-based generating
plants is scheduled to be completed by June 1999. Southern is subject to the
informational requirements of the Securities Exchange Act of 1934, as amended,
and, in accordance therewith, files reports and other information with the 
SEC.


During Phase III of its program, Oglethorpe plans to assess the Year 2000
readiness of other significant third parties, including power marketers (such as
LEM and Morgan Stanley), other utilities and vendors of materials and services.
Oglethorpe has identified over 400 such third parties, and is in the process of
prioritizing the parties from which Oglethorpe will require Year 2000
information. Oglethorpe expects to begin requesting information from these third
parties in the second quarter of 1999. This information will allow Oglethorpe to
perform contingency planning, including assessing the need to identify
alternative vendors. Oglethorpe may not be able to identify all third parties'
Year 2000 problems, and may not be able to develop adequate contingency plans if
third parties do not correct their Year 2000 problems.

PROJECT COSTS. In addition to the $4.5 million expected to be paid to GPC,
Oglethorpe currently estimates costs of approximately $370,000 to upgrade its
internal systems, including those relating to Rocky Mountain. To date,
Oglethorpe has spent approximately $270,000 of the estimated $370,000 on this
effort. In addition, Oglethorpe is upgrading or replacing its externally
developed financial accounting, procurement and materials management, and human
resource/payroll systems to improve functionality and to avoid Year 2000
remediation efforts on those systems, at an estimated cost of approximately $4.0
million, of which $745,000 has been spent. Oglethorpe's policy is to expense as
incurred the maintenance and modification costs of existing software, including
those associated with


                                       15
<PAGE>

the Year 2000 project, and to capitalize and amortize over its useful life the
cost of new software. Oglethorpe also estimates that approximately $770,000 will
be incurred for Phase III, including costs associated with performing a
management evaluation of the Phase I and Phase II activities, and to perform the
contingency planning and the preparedness evaluation of key business
relationships. These costs are estimates, and actual costs could be higher.

Oglethorpe plans to pay for Year 2000 costs with general corporate funds. Year
2000 costs are being recovered from the Members through Oglethorpe's rates.

RISK ASSESSMENT. Oglethorpe has implemented a detailed process to minimize the
possibility of power supply interruptions related to Year 2000 challenges and
expects its IT and non-IT systems to be Year 2000 ready by December 31, 1999.
The most reasonably likely worst case scenario would be service interruptions to
Oglethorpe's Members or the Members' retail consumers. These scenarios include
the loss of a generating unit or a source of purchased power, or a disruption in
transmission or distribution services by GTC or the Members. Because Oglethorpe
is taking prudent steps to prepare for the Year 2000 challenges, it expects any
interruptions in power supply to be isolated and short in duration. However,
because of material relationships with third parties, Oglethorpe may not be 
able to fully assess the possibility of service interruptions to the ultimate 
retail consumers.

There is also risk to the Members of billing and other business system failures
and of some reduction in net margin caused by interruptions in service and
reduced electrical demand by consumers because of their Year 2000 issues.
Oglethorpe has not fully assessed the impact of these risks on its financial
condition or results of operations.

Actual results, costs, risks, or worst case scenarios related to Year 2000
issues may materially differ from those that Oglethorpe expects or estimates.
Factors that might cause material differences include, but are not limited to,
Oglethorpe's ability to locate and correct all microprocessors that are not Year
2000 ready, the readiness of third parties, and Oglethorpe's ability to develop
adequate contingency plans to respond to foreseen or unforeseen Year 2000
problems.

CONTINGENCY PLANNING. Oglethorpe recently began developing contingency plans for
its IT and non-IT systems. To assist Oglethorpe in this effort, the consulting
firm KPMG has been engaged to provide leadership and expertise to the Oglethorpe
staff developing the contingency plans. The contingency plans will also focus on
non-compliance by material third parties and assess the need to identify
alternative vendors and the need to increase inventory of materials and
supplies. The contingency plans are expected to be in place by June 30, 1999 and
will continue to be evaluated and tested throughout 1999. The goal of the
contingency planning process is to keep any service interruptions to a minimum
and of short duration and to avoid disruptions in its billing or other
management processes. Oglethorpe may incur additional costs as a result of its
contingency plans.

<PAGE>

Oglethorpe Power notifies Georgia Power of the intent to add or delete more than
one (1) Short Term Resource in any given Hour, such notice shall be deemed
ineffective. Georgia Power shall use reasonable best efforts to notify
Oglethorpe Power that such utilization schedule has been deemed ineffective as
soon as practicable following such event.

                  (c) Oglethorpe Power shall be required to make such changes to
its energy utilization schedules from time to time during a Day to reflect any
recalls made by Georgia Power or its agent, pursuant to Section 4.8, of the
Short Term Resources. Oglethorpe Power shall make changes as and when directed
by Georgia Power or its agent. Oglethorpe Power shall be deemed to have reduced
its energy utilization schedule from such a Short Term Resource, automatically
as and when, and to such level of energy as Georgia Power or its agent deems
appropriate under the circumstances and Section 4.8 (including without
limitation zero (-0-)), whether or not Oglethorpe Power has made such changes as
aforesaid. Any changes to Oglethorpe Power's utilization schedules made or
deemed to have been made pursuant to this Section 4.3(c) shall be treated as
"energy scheduled . . . but not delivered" pursuant to Section 4.8(c).

         4.4      MINIMUM UTILIZATION NOTICE.

                  (a) Oglethorpe Power must give Georgia Power or its agent at
least twenty (20) minutes' prior notice that Oglethorpe Power wishes to utilize
energy from a Short Term Resource during an Hour in order to actually utilize

from its utilization schedule for such Hour only until twenty (20) minutes prior
to such Hour.

                  (c) Oglethorpe Power's schedule of energy utilization from all
Short Term Resources during a given Hour shall become final at twenty (20)
minutes prior to such Hour and shall not thereafter be subject to change by
Oglethorpe Power.
                  (d) If Oglethorpe Power gives Georgia Power or its agent
notice pursuant to Section 4.2 or 4.3 that Oglethorpe Power wishes to schedule
energy utilization from a given Short Term Resource upon less than twenty (20)
minutes' prior notice, then such energy utilization notice shall be deemed
ineffective as to such Short Term Resource for such Hour (even if Oglethorpe
Power complied with the provisions of Sections 4.5 and 4.6 concerning minimum
utilization duration and maximum utilization Hours). Georgia Power shall use
reasonable best efforts to notify Oglethorpe Power that such utilization
schedule has been deemed ineffective as soon as practicable following such
event.

utilized during a given Day, then Oglethorpe Power must always schedule 
energy utilization from each such Short Term Resource at no less than six (6) 
consecutive Hours. If Oglethorpe Power gives Georgia Power or its agent 
notice pursuant to Sections 4.2 or 4.3 that Oglethorpe Power wishes to 
schedule any Short Term Resource such that such Short Term Resource is being 
utilized less than six (6) consecutive Hours, then Oglethorpe Power shall 
nevertheless be deemed to have scheduled energy utilization from such Short 
Term Resource for a period of six (6) consecutive Hours starting with the 
first Hour scheduled for such Short Term Resource in said notice. Georgia 
Power shall use reasonable best efforts to notify Oglethorpe Power that such 
utilization schedule has been deemed changed as soon as practicable following

         4.6      MAXIMUM UTILIZATION HOURS. Oglethorpe Power may not 
schedule energy utilization from the Short Term Resources in excess of 2500 
Hours during the Term of this Agreement. For purposes of determining such 
2500 Hours of maximum energy utilization, if Oglethorpe Power schedules one 
(1) or more Short Term Resource in a given Hour, such Hour shall count as one 
(1) Hour of energy utilization. If Oglethorpe Power gives Georgia Power or 
its agent notice pursuant to Sections 4.2 or 4.3 that Oglethorpe Power wishes 
to schedule any Short Term Resource such that the Short Term Resources are 
being utilized in excess of 2500 Hours during the Term of this Agreement, 
such notice shall be ineffective. Georgia Power shall use reasonable best 
efforts to notify Oglethorpe Power that such utilization schedule has been 
deemed ineffective as soon as practicable following such event.

         4.7      ENERGY UTILIZATION. For purposes of calculating both the 
Monthly Energy Charge for each of the Short Term Resources and the "Actual

associated with each of the Short Term Resources, Oglethorpe Power shall be 
deemed to have utilized during each Hour all energy either:

                           (1) shown on Oglethorpe Power's final energy
         utilization schedule (under Section 4.4(c)) during each such Hour for
         such Short Term Resource, except as such energy utilization schedule
         may have been deemed ineffective under Section 4.2, 4.3(b), 4.4(d) or
         4.6.

                           (2) deemed to have been scheduled by Oglethorpe Power
         during each such Hour from such Short Term Resource under Section
         4.3(c) or 4.5.

         4.8      RECALL OF SHORT TERM RESOURCES.

                  (a) If Georgia Power or its agent determines in its sole
discretion that it is necessary or appropriate to interrupt (i) Georgia Power
retail interruptible load (retail electric

         5.9      CHANGES TO UTILIZATION SCHEDULES.

                  (a) Oglethorpe Power may make changes to its schedule of
energy utilization from the committed LT Resources for a given Day from time to
time during such Day, in Oglethorpe Power's discretion, subject to the
provisions of this Section 5.9 and of Sections 5.10, 5.11, 5.12 and 5.13
concerning minimum utilization notice, minimum utilization levels, maximum
utilization levels and ramping.

                  (b) Oglethorpe Power shall use good faith efforts to notify
Georgia Power or its agent of such changes as soon as practicable after
Oglethorpe Power decides to make any such changes. Such notices shall contain
information regarding the increases or decreases in the amount of energy, in
megawatt-hours per Hour (MWH/H), that Oglethorpe Power expects to utilize from
each of the committed LT Resources during each Quarter Hour affected by such
changes.

                  (c) Oglethorpe Power shall be required to make such changes to
its energy utilization schedules from time to time during a Day to reflect any
changes made by Georgia Power or its agent, pursuant to Section 5.15, to the
Load Carrying Capability of a LT Resource. Oglethorpe Power shall make such
changes as and when directed by Georgia Power or its agent. Oglethorpe Power
shall be deemed to have reduced its energy utilization schedule from such a LT
Resource, automatically as and when, and to such level of energy as Georgia
Power or its agent deems appropriate under the circumstances and Section 5.15
(including without limitation zero (-0-)), whether or not Oglethorpe Power has
made such changes as aforesaid.

                  (d) Oglethorpe Power's energy utilization schedules, as
changed (or as deemed to have been changed) by Oglethorpe Power from time to
time pursuant to this Section 5.9, shall always continue to be consistent on an
Hour by Hour basis with Oglethorpe Power's then current 

                                       27
<PAGE>

commitment schedule of the LT Steam Resource. Oglethorpe Power may not pursuant
to this Section 5.9 add the LT Steam Resource to any energy utilization schedule
for a given Hour of a given Day, if the LT Steam Resource has not been properly
committed by Oglethorpe Power for such Hour pursuant to Sections 5.2 through
5.6.

                  (e) If Oglethorpe Power gives Georgia Power or its agent
notice pursuant to this Section 5.9 that Oglethorpe Power wishes to schedule
energy utilization from the LT Steam Resource for a given Hour, when the LT
Steam Resource has not been properly committed by Oglethorpe Power for such Hour
pursuant to Sections 5.2 through 5.6, then such energy utilization notice shall
be ineffective as to the LT Steam Resource for such Hour (even if Oglethorpe
Power complied with the provisions of Sections 5.10, 5.11, 5.12 and 5.13
concerning minimum utilization notice, minimum utilization levels, maximum
utilization levels and ramping). Georgia Power shall use reasonable best efforts
to notify Oglethorpe Power that such utilization schedule has been deemed
ineffective as soon as practicable following such event.

         5.10     MINIMUM UTILIZATION NOTICE.

                  (a) Oglethorpe Power must give Georgia Power or its agent at
least one (1) Quarter Hour's prior notice that Oglethorpe Power wishes to
utilize energy from a LT Resource during a Quarter Hour in order to actually
utilize energy from such LT Resource during such Quarter Hour.

                  (b) Once Oglethorpe Power has given Georgia Power or its agent
notice pursuant to Section 5.8 or 5.9 that Oglethorpe Power wishes to utilize
energy from a given committed LT Resource in a given Quarter Hour at a given
level of energy, Oglethorpe Power may increase or decrease the level of energy
at which such LT Resource is to be utilized during such Quarter Hour only until
one (1) Quarter Hour prior to such Quarter Hour.

                                       28
<PAGE>

                  (c) Oglethorpe Power's schedule of energy utilization from all
committed LT Resources during a given Quarter Hour shall become final at the
commencement of the immediately preceding Quarter Hour and shall not thereafter
be subject to increase or decrease by Oglethorpe Power.

                  (d) If Oglethorpe Power gives Georgia Power or its agent
notice pursuant to Section 5.8 or 5.9 that Oglethorpe Power wishes to schedule
energy utilization from a given LT Resource upon less than one (1) Quarter
Hour's prior notice, then such energy utilization notice shall be ineffective as
to such LT Resource for such Quarter Hour (even if Oglethorpe Power complied
with the provisions of Sections 5.11, 5.12 and 5.13 concerning minimum
utilization levels, maximum utilization levels and ramping). Georgia Power shall
use reasonable best efforts to notify Oglethorpe Power that such utilization
schedule has been deemed ineffective as soon as practicable following such
event.

                  (e) If Oglethorpe Power gives Georgia Power or its agent
notice pursuant to Section 5.8 or 5.9 that Oglethorpe Power wishes to schedule
energy utilization from the LT Peaking Resource in a given Quarter Hour (Y) that
is not equal to the energy utilization scheduled in the immediately previous
Quarter Hour (X), then for the immediately following Quarter Hour (Z),
Oglethorpe Power must schedule the identical utilization as scheduled for the
given Quarter Hour (Y). If in such following Quarter Hour (Z) Oglethorpe Power
schedules energy utilization from the LT Peaking Resource that is not identical
to that scheduled for the given Quarter Hour (Y), then Oglethorpe Power shall
nevertheless be deemed to have scheduled energy utilization from the LT Peaking
Resource in such following Quarter Hour (Z) at such level of energy equal to the
given Quarter Hour's (Y's) utilization schedule. Georgia Power shall 

                                       29
<PAGE>

use reasonable best efforts to notify Oglethorpe Power that such utilization has
been deemed scheduled as soon as practicable following such event.

         5.11     MINIMUM UTILIZATION LEVELS.

                  (a) If the LT Steam Resource is committed during a given Hour,
then Oglethorpe Power must always schedule energy utilization from the LT Steam
Resource at no less than its then current Minimum Operating Level. If the LT
Steam Resource is committed during an Hour, but Oglethorpe Power does not
schedule energy utilization from the LT Steam Resource during each Quarter Hour
or schedules energy utilization from the LT Steam Resource at less than its then
current Minimum Operating Level, then Oglethorpe Power shall nevertheless be
deemed to have scheduled energy utilization from the LT Steam Resource at its
then current Minimum Operating Level. Georgia Power shall use reasonable best
efforts to notify Oglethorpe Power that such utilization has been deemed
scheduled as soon as practicable following such event.

                  (b) This Section 5.11 shall not apply to the LT Peaking
Resource.

         5.12     MAXIMUM UTILIZATION LEVELS. Oglethorpe Power may not 
schedule energy utilization from any committed LT Resource during any Quarter 
Hour at any level of energy in excess of the then current Load Carrying 
Capability of such LT Resource. If Oglethorpe Power schedules energy 
utilization from a given LT Resource during a Quarter Hour at a level of 
energy that is in excess of the then current Load Carrying Capability of such 
LT Resource, then Oglethorpe Power shall nevertheless be deemed to have 
scheduled energy utilization from such LT Resource at such level of energy 
equal to the then current Load Carrying Capability of such LT Resource. 
Georgia Power shall use reasonable best efforts to notify Oglethorpe Power 
that such utilization has been deemed scheduled as soon as practicable 
following such event.

         5.13     LT STEAM RESOURCE RAMPING.

                  (a) During the first (1st) Hour after the commencement of a
commitment of a LT Steam Resource pursuant to and as allowed by Sections 5.2,
5.3, 5.4 and 5.6, Oglethorpe Power must schedule energy utilization from the LT
Steam Resource at a level of energy that is equal to the then current Minimum
Operating Level of the LT Steam Resource. If Oglethorpe Power schedules energy
utilization from the LT Steam Resource during such an Hour at a level of energy
greater than or less than such level of energy, then Oglethorpe Power shall
nevertheless be deemed to have scheduled energy utilization from the LT Steam
Resource at such level of energy for such Hour. Georgia Power shall use
reasonable best efforts to notify Oglethorpe Power that such utilization has
been deemed scheduled as soon as practicable following such event.

                  (b) During the first (1st) Hour after the commencement of a
decommitment of the LT Steam Resource pursuant to and as allowed by Sections
5.2, 5.3 and 5.5, Oglethorpe Power must schedule energy utilization from the LT
Steam Resource at a level of energy that is equal to the then current Minimum
Operating Level of the LT Steam Resource. If Oglethorpe Power schedules energy
utilization from the LT Steam Resource during such an Hour at a level of energy
less than or greater than such level of energy, then Oglethorpe Power shall
nevertheless be deemed to have scheduled energy utilization from the LT Steam
Resource at such level of energy for such Hour. Georgia Power shall use
reasonable best efforts to notify Oglethorpe Power that such utilization has
been deemed scheduled as soon as practicable following such event.

                  (c) During the second (2nd) Hour after the commencement of a
decommitment of the LT Steam Resource pursuant to and as allowed by Sections
5.2, 5.3 and 5.5, and thereafter 

                                       31
<PAGE>

unless and until the LT Steam Resource is again committed pursuant to and as
allowed by Sections 5.2, 5.3, 5.4 and 5.6, Oglethorpe Power may not schedule
energy utilization from the LT Steam Resource at any level of energy. If
Oglethorpe Power schedules energy utilization from the LT Steam Resource during
any such Hour or Hours, then Oglethorpe Power shall nevertheless be deemed not
to have scheduled any energy utilization from the LT Steam Resource at all for
any or all of such Hours. Georgia Power shall use reasonable best efforts to
notify Oglethorpe Power that such utilization has been deemed scheduled as soon
as practicable following such event.

                  (d) This Section 5.13 shall not apply to the LT Peaking
Resource.

         5.14     ENERGY UTILIZATION. For purposes of calculating both the 
Monthly Energy Charge for each of the LT Resources and the "Actual Hourly 
Resource Utilization" associated with each of the LT Resources (as such term 
is defined and used in the RCSA), Oglethorpe Power shall be deemed to have 
utilized during each Hour the average of all energy either:

                           (1) shown on Oglethorpe Power's final energy
         utilization schedule (under Section 5.10(c)) during each Quarter Hour
         of such Hour for such LT Resource, except as such energy utilization
         schedule may have been deemed ineffective under Section 5.8(a), 5.8(d),
         5.9(e) or 5.10(d); or

                           (2) deemed to have been scheduled by Oglethorpe Power
         during each Quarter Hour of such Hour from such LT Resource under
         Section 5.9(c), 5.10(e), 5.11(a), 5.12, 5.13(a), 5.13(b) or 5.13(c).

         5.15     REDUCTION OF LOAD CARRYING CAPABILITY.

                  (a) If Georgia Power or its agent determines in its sole
discretion that it is necessary or appropriate for the Georgia system to shed
firm territorial requirements load, 

                                       32
<PAGE>

determined consistent with NERC guidelines, then the Load Carrying Capability of
one (1) or more of the LT Resources that are committed at the time of such load
shedding shall automatically be reduced by the amounts computed by Georgia Power
or its agent as provided in Sections 5.15(b) and 5.15(c) until such time as
Georgia Power advises Oglethorpe Power that Oglethorpe Power can recommence
serving load as provided in Section 5.15(d).

                  (b) The reduction ratio to be used in computing Oglethorpe
Power's reduction amount shall be equal to the quotient of:

                           (1) the summation of the then current Load Carrying
         Capability of each of the LT Resources that are committed at the time
         of such load shedding; divided by

                           (2) the sum of:

                                    (i) Georgia Territorial Resource
                           Requirements at such time (not including its
                           obligations to serve Oglethorpe Power under this
                           Agreement); plus

                                    (ii) the summation determined under Section
                           5.15(b)(1).

                  (c) Oglethorpe Power's aggregate reduction amount, in
megawatts (MW), shall be equal to the product of:

                           (1) the aggregate amount of load that Georgia Power
         or its agent determines in its discretion is necessary or appropriate
         for the Georgia system to shed; times

                           (2) the reduction ratio computed by Georgia Power or
its agent pursuant to Section 5.15(b).

The Load Carrying Capability of the one (1), of the LT Resources that are
committed at the time of such load shedding, which has the highest then current
Monthly Energy Rate, shall then 

                                       33
<PAGE>

automatically be reduced by the amount of such reduction amount until the Load
Carrying Capability of such LT Resource is equal to the then current Minimum
Operating Level of such LT Resource. If a portion of such reduction amount
remains unapplied, then the Load Carrying Capability of the other LT Resource
shall be automatically reduced by Georgia Power or its agent, until all of the
reduction amount has been applied. The Load Carrying Capability of such LT
Resources will be reduced below each such LT Resource's respective Minimum
Operating Level, in a manner corollary to the foregoing, if a portion of such
reduction amount remains unapplied after each of such LT Resource's Load
Carrying Capability has been reduced to such LT Resource's Minimum Operating
Level.

                  (d) Oglethorpe Power agrees that, in such event, it will
immediately change (or allow the change of by Georgia Power or its agent) its
energy utilization from the LT Resources, as provided in Section 5.9. In
addition, in such event, Oglethorpe Power agrees that it will take any and all
actions necessary or appropriate to accomplish the foregoing, including, but not
limited to, shedding load served by the LT Resources. Oglethorpe Power may
recommence serving load shed by Oglethorpe Power pursuant to this Section 5.15
when Georgia Power or its agent advises Oglethorpe Power that it is appropriate
to do so in light of system security needs.

                  (e) Georgia Power agrees that, if the Load Carrying Capability
of any one or more LT Resources is reduced pursuant to this Section 5.15, then
Georgia Power shall give Oglethorpe Power a credit in the following Monthly
invoice in an amount for each such LT Resource that is equal to the product of:

                           (1) Oglethorpe Power's aggregate reduction amount, in
         megawatts (MW), as determined pursuant to Section 5.15(c); times

                           (2) the quotient of:

                                       34
<PAGE>

                                    (i) the Monthly Capacity Rate(s) for each of
                           the LT Resources whose Load Carrying Capability was
                           reduced pursuant to Section 5.15(c) (applied by
                           Georgia Power in portions as necessary to accommodate
                           the provisions of Section 5.15(c)), for the Month in
                           which such load shedding occurs, in dollars per
                           kilowatt-month ($/KW-Mo); divided by

                                    (ii) the number of Hours in such Month;
                           times

                           (3) the number of Hours in the period over which such
                  load shedding occurred; times

                           (4) one thousand (1,000).

         5.16     DELIVERY OF AND PAYMENT FOR ENERGY. Georgia Power's and 
Oglethorpe Power's respective rights and obligations concerning the delivery 
of and payment for energy utilization scheduled by Oglethorpe Power from the 
LT Resources during any given Hour of the Term shall be as set forth in 
Article III.

         5.17     EMERGENCY DECOMMITMENT. Notwithstanding the provisions of 
Section 5.5, if all "OPC Off-System Resources" (as such term is defined and 
used in the RCSA) have been interrupted pursuant to Section 8.1 of the RCSA 
and Oglethorpe Power continues to have surplus energy as defined in Article 
XII of the RCSA, Oglethorpe Power may decommit the LT Steam Resource on one 
(1) Quarter Hour's prior notice to Georgia Power, effective at the start of 
any subsequent Quarter Hour.

         5.18     RCSA TREATMENT.

                  (a) The LT Steam Resource shall be deemed "Qualifying
Resources - Spinning" (as such term is defined and used in Sections 11.5 and
11.6 of the RCSA).

                                       35
<PAGE>

                  (b) Fifteen (15) percent of the LT Peaking Resource shall be
deemed "Qualifying Resources Supplemental" (as such term is defined and used in
Section 11.6 of the RCSA).

                  (c) The "Difference" utilized in the calculation of the
"Back-Up Capacity Charge" (as such terms are defined and used in Section 12.3 of
the RCSA) shall include the difference between (i) the sum of the Actual Hourly
Resource Utilization of all LT Resources, less (ii) the sum of the then current
Load Carrying Capability of all LT Resources.

<PAGE>

                  (c) The procedure set forth in Sections 6.1(a) and 6.1(b) for
Oglethorpe Power's payment to Georgia Power of Monthly Capacity Payments is
subject to periodic temporary modification for phase-in of an increase or
decrease in the Monthly Capacity Charges, if and as provided for in Part 6 of
the Schedules in the event that a Monthly Capacity Charge should become subject
to an adjustment as provided for in said Part 6 of said Schedule.

         6.2      ENERGY BILLING AND PAYMENT.

                  (a) As promptly as practicable after the commencement of each
Month during the Term, Georgia Power shall send Oglethorpe Power an invoice
stating the Monthly Energy Payment for such Month, together with a statement of
any other amounts then due by Oglethorpe Power to Georgia Power pursuant to the

                  (b) All invoices of Monthly Energy Payments shall be due and
payable on or before the tenth (10th) Day after Oglethorpe Power's receipt of
such invoice. If such tenth (10th) Day after Oglethorpe Power's receipt is not a
banking Day, then payment shall be due on the next succeeding banking Day.
Oglethorpe Power shall make payment to Georgia Power in accordance with such
invoices on or before the date due in immediately available funds through wire
transfer of funds or other means acceptable to Georgia Power. If Oglethorpe
Power does not make a Monthly Energy Payment on or before such tenth (10th) Day,
then interest shall be added to the overdue payment, from the date such overdue
payment was due until such overdue payment together with interest is paid, which
interest shall accrue in simple interest terms per annum at the Interest Rate.

                  (c) With each Monthly energy invoice Georgia Power will
provide Oglethorpe Power a Monthly statement of the Monthly Energy Rates and
Hourly Energy Rates upon which 

                                       37
<PAGE>

the Monthly Energy Payment was based. Georgia Power may combine its Monthly
capacity and energy invoices into a single invoice, in Georgia Power's
discretion.

                  (d) The procedure set forth in Sections 6.2(a) and 6.2(b) for
Oglethorpe Power's payment to Georgia Power of Monthly Energy Payments is
subject to periodic temporary modification for phase-in of an increase or

         6.3      BILLING DISPUTES AND FINAL ACCOUNTING.

                  (a) If Oglethorpe Power questions or contests the amount of
any payment claimed by Georgia Power to be due pursuant to this Agreement,
Oglethorpe Power may make such payment under protest and thereafter shall be
reimbursed by Georgia Power for any amount in error after the settlement of such
question or contest, in accordance with this Section 6.3; PROVIDED, HOWEVER,
that no disagreement or dispute of any kind between Oglethorpe Power and Georgia
Power concerning any matter, including, without limitation, the amount of any
payment due from Oglethorpe Power or the correctness of any charge made by
Georgia Power to Oglethorpe Power, shall permit Oglethorpe Power to delay or
withhold any payment pursuant to this Agreement except as specifically otherwise
provided for in Section 6.7.

                  (b) In the event that Oglethorpe Power, by timely notice to
Georgia Power, questions or contests the correctness of any such charge or
credit, Georgia Power shall promptly review the questioned charge or credit and
shall notify Oglethorpe Power, within sixty (60) Days following receipt by
Georgia Power of such notice from Oglethorpe Power, of the amount of any error
and the amount of any payment or reimbursement that Oglethorpe Power is required
to make or is entitled to receive in respect of such alleged error. Not later
than the fifth (5th) 

                                       38
<PAGE>

banking Day after receipt by Oglethorpe Power of such notice from Georgia Power
as to the amount of any payment that Oglethorpe Power is required to make,
Oglethorpe Power shall make payment to Georgia Power in immediately available
funds. If Georgia Power is required to make any reimbursement to Oglethorpe
Power, Georgia Power shall notify Oglethorpe Power of the amount of such
reimbursement and the need to send an invoice to Georgia Power for such
reimbursement and make such reimbursement not later than the fifth (5th) banking
Day after Georgia Power receives an invoice from Oglethorpe Power in the amount
of such required reimbursement. Payments and reimbursements made by either
Oglethorpe Power or Georgia Power under this Section 6.3(b) shall include
interest from the later of the date the original payment was received or the
date the original payment was due until the date such payment or reimbursement
together with interest is made, which interest shall accrue in simple interest
terms per annum at the Interest Rate. Oglethorpe Power shall have until the one
hundred eightieth (180th) Day after receipt of an invoice to question or contest
the correctness of any charge or credit made to Oglethorpe Power during such
Month pursuant to Section 6.1 or 6.2, after which time the correctness of all
such charges and credits shall be conclusively presumed.

                  (c) If Oglethorpe Power disputes Georgia Power' resolution
under Section 6.3(b) of any question or contest by Oglethorpe Power of the
correctness of any charge or credit made to Oglethorpe Power pursuant to Section
6.1 or 6.2, then at Oglethorpe Power's request Georgia Power and Oglethorpe
Power agree to use their reasonable best efforts to achieve a mutually
acceptable solution to such dispute. In the event that either Georgia Power or
Oglethorpe Power believes that any such efforts by Georgia Power and Oglethorpe
Power have been or will be unsuccessful, then it may submit such dispute to, for
resolution by, the Joint Committee. If the Joint Committee fails to resolve such
dispute by the third (3rd) regularly scheduled meeting 

                                       39
<PAGE>

following the meeting at which Georgia Power or Oglethorpe Power first submitted
such dispute to the Joint Committee, then either Oglethorpe Power or Georgia
Power may submit such dispute to, for resolution by, the respective Chief
Executive Officers of Oglethorpe Power and Georgia Power. If the Chief Executive
Officers fail to resolve such dispute within a reasonable period of time after
it is submitted to them, then either Oglethorpe Power or Georgia Power may
resort to any remedy, at law or in equity, that may be available therefor. If
either Georgia Power or Oglethorpe Power submits such dispute to the Joint
Committee, then neither of them shall thereafter have any further obligation to
use its reasonable best efforts to achieve a mutually acceptable solution as
aforesaid.

                  (d) Notwithstanding the foregoing provisions of this Section
6.3, if Oglethorpe Power is then in default in respect of any payments required
to be made under this Agreement, Georgia Power may withhold such reimbursement.

                  (e) Georgia Power will provide Oglethorpe Power with such
information as is reasonably required by Oglethorpe Power in order to account
for payments made pursuant to this Section 6.3 on Oglethorpe Power's books.

         6.4      AVAILABILITY OF RECORDS. Georgia Power will for each Month 
of the Term, at all times prior to the end of such one hundred eighty (180) 
Day period set forth in Section 6.3(b), make available to Oglethorpe Power, 
subject to the confidentiality provisions of Article XV of the RCSA, and 
Oglethorpe Power may audit such books and records of Georgia Power as are 
necessary for Oglethorpe Power to verify the basis for and amounts of 
adjustments to Short Term Resource energy utilization made pursuant to 
Section 4.8 and to LT Resources' Load Carrying Capability pursuant to Section 
5.15, and to calculate the Monthly Capacity Payments and Monthly Energy 
Payments and thereby to verify the accuracy of the amounts billed to 

                                       40
<PAGE>

Oglethorpe Power pursuant to Sections 6.1 and 6.2. No
payment made pursuant to the provisions of this Article VI shall constitute a
waiver of any right of Oglethorpe Power under Section 6.3 to question or contest
the correctness of any charge or credit by Georgia Power or to dispute Georgia
Power's resolution of any such question or contest.

         6.5      IMPLEMENTATION COSTS. Oglethorpe Power hereby agrees to 
reimburse Georgia Power for all costs incurred by Georgia Power or its agent 
(except attorney's fees) in connection with implementing this Agreement or 
the rates and procedures provided for herein. Oglethorpe Power shall pay 
Georgia Power the amount of such costs within ten (10) Days after Georgia 
Power delivers an invoice therefor to Oglethorpe Power. The provisions of 
6.2(b), 6.3, 6.4 and 6.6 shall apply to the payment and verification of such 
invoice. Georgia Power agrees that Georgia Power may not duplicate its 
recovery of any costs both under this Section 6.5 and under Section 16.1 of 
the RCSA.

         6.6      FAILURE TO MAKE PAYMENTS.

                  (a) If Oglethorpe Power fails to pay when due the full amounts
of any payment(s) required by Sections 6.1, 6.2, 6.3 or 6.5 then:

                           (1) Oglethorpe Power shall have no right to any
         capacity or energy hereunder, or to exercise any of its rights under
         this Agreement; and

                           (2) if the RCSA is then in effect, the LT Schedules
         shall be deemed not to be "Qualifying Resources - Spinning" or
         "Qualifying Resources - Supplemental" and the "Difference" utilized in
         the calculation of the "Back-Up Capacity Charge" shall exclude all LT
         Schedules (as such terms are defined and used in the RCSA);

                                       41
<PAGE>

from the date such overdue payment(s) were due until Oglethorpe Power has paid
the full amounts of all such overdue payments to Georgia Power (including,
without limitation, interest) as required by said Sections 6.1, 6.2, 6.3 and
6.5.
                  (b) Georgia Power agrees that, if Oglethorpe Power pays to
Georgia Power such overdue payment(s) during the five (5) Day period allowed for
curing a failure to make payment provided for in Section 10.1(a) (including,
without limitation, interest) and undertakes to recommence making its other
payments to Georgia Power as and when due hereunder, Georgia Power will
recommence supplying capacity and energy to Oglethorpe Power hereunder no later
than the end of the five (5) Day period provided for in Section 10.1(a).

                  (c) In addition to the rights granted in Sections 6.3, 6.6(a),
and Article X, Georgia Power may take any action, at law or in equity, to
enforce this Agreement and to recover any and all unrecovered damages and
expenses and other losses, costs and liabilities (including, without limitation,
reasonable attorneys' fees and expenses) incurred or suffered by Georgia Power
as a result of or in connection with any default in payment by Oglethorpe Power
under this Agreement.

         6.7      LIMITED WITHHOLDING OF PAYMENTS.

                  (a) If Oglethorpe Power questions or contests the amount of
any payment claimed by Georgia Power in any Month to be due pursuant to this
Agreement, which amount is more than twice as large as the highest amount
previously claimed by Georgia Power to be due pursuant to this Agreement in any
other Month of the Term, then Oglethorpe Power may withhold payment of the
lesser of:

                           (1) the disputed portion of such amount; or

                                       42
<PAGE>

                           (2) that portion of such amount which is in excess of
         twice such highest Monthly amount previously claimed by Georgia Power
         to be due pursuant to this Agreement. 


         (b) If Oglethorpe Power acquires the right under Section 6.7(a) to
withhold any portion of a payment claimed by Georgia Power to be due pursuant to
this Agreement and chooses to exercise such right, then Oglethorpe Power shall
immediately notify Georgia Power that it is questioning or contesting the
correctness of such amount and shall also nevertheless tender to Georgia Power
on a timely basis under Sections 6.1 and 6.2 that portion of such amount which
Oglethorpe Power is not permitted to withhold under Section 6.7(a). Georgia
Power and Oglethorpe Power shall then resolve such dispute in accordance with
the procedure provided in Sections 6.3(b) and 6.3(c). If Oglethorpe Power is
required pursuant to the resolution of such dispute to pay any portion of the
withheld amount to Georgia Power, then interest shall be added to the portion so
to be paid, from the date such payment was due until such payment together with
interest is paid, which interest shall accrue in simple interest terms per annum
at the Interest Rate.

                                   ARTICLE VII

                    CERTAIN CAPACITY AND ENERGY SALE MATTERS

         7.1      SERVICE RENDERED. Georgia Power shall provide and 
Oglethorpe Power shall pay for capacity and energy pursuant to the Tariff, 
the terms of this Agreement and the Schedules attached hereto. To the extent 
the terms and conditions of the Tariff are inconsistent with those set forth 
in this Agreement or in the Schedules, the provisions of this Agreement and 
Schedules shall control.

                                       43
<PAGE>

         7.2      RESALE. Oglethorpe Power shall have the right to resell any 
part or all of the Resource Capacity or any or all of the energy scheduled by 
Oglethorpe Power hereunder, to any person or entity, subject to the terms and 
conditions of this Agreement. Oglethorpe Power hereby indemnifies and holds 
Georgia Power and its agent harmless from and against any and all losses, 
costs, liabilities, damages and expenses (including, without limitation, 
attorneys' fees and expenses) of any kind incurred or suffered by Georgia 
Power or its agent pursuant to, as a result of or in connection with any such 
resale of capacity, energy or both, except for losses, costs, liabilities, 
damages and expenses (including, without limitation, attorneys' fees and 
expenses) incurred or suffered by Georgia Power or its agent as a direct 
result of any action of Georgia Power that is not Prudent Utility Practices 
or of Georgia Power's or its agents' willful misconduct. This Section 7.2 
does not give Oglethorpe Power any rights to assign or delegate this 
Agreement or any of its rights or obligations hereunder, which Oglethorpe 
Power acknowledges that it may do only as allowed by Section 9.2.

         7.3      CHARACTER OF TRANSACTIONS. The sale by Georgia Power to 
Oglethorpe Power of capacity and associated energy under this Agreement does 
not constitute either:

                  (1) a sale, lease, transfer or conveyance of an ownership
         interest in or to any generation facilities or resources, including
         without limitation the Units; or

                  (2) a dedication of ownership or an entitlement to the
         capacity or output of any generation facilities or resources, including
         without limitation the Units.

Furthermore, Oglethorpe Power acknowledges and agrees that Georgia Power or its
agent shall have the sole authority, which Georgia Power or its agent may
exercise in its discretion, to manage, control, operate and maintain all of the
Units. (Georgia Power acknowledges, however, 

                                       44

<PAGE>

that this Section 7.3 is not intended and shall not be construed to reduce
Oglethorpe Power's rights to capacity and energy under Article II, III, IV or
V.)

         7.4      CONSTANCY OF SUPPLY.

                  (a) Georgia Power does not guarantee or warrant that Georgia
Power will supply a constant or uninterrupted supply of capacity or energy under
this Agreement. Oglethorpe Power hereby agrees that Georgia Power is not
required to make capacity available to Oglethorpe Power under this Agreement at
all times during the Term or to deliver under this Agreement a constant or
uninterrupted supply of energy.

                  (b) For actions taken pursuant to Sections 4.8 and 5.15,
Georgia Power shall not be in breach of this Agreement by reason of, and shall
have no liability whatsoever to Oglethorpe Power for, any failure to make
capacity available hereunder, or for any failure to deliver or any interruption
in the delivery of energy hereunder or for any deficiency in the quality of
service hereunder.

                  (c) For any other actions taken pursuant to this Agreement,
Georgia Power shall not be in breach of this Agreement by reason of, and shall
have no liability whatsoever to Oglethorpe Power for, any failure to make
capacity available hereunder, or for any failure to deliver or any interruption
in the delivery of energy hereunder or for any deficiency in the quality of
service hereunder; PROVIDED, HOWEVER, the foregoing exculpatory clause of this
Section 7.4(c) shall not apply to any such failure that is the direct result of
any action of Georgia Power that (i) is not Prudent Utility Practices, (ii) is
of Georgia Power's or its agent's willful misconduct, or (iii) is done for
purely economic reasons.

         7.5      MARKET RATE TARIFF.

                  (a) It is the expressed intent of the Parties that this
Agreement and the attached Schedules be accepted by the FERC as a sale pursuant
to the Tariff without any modifications of its charges, terms and conditions and
without additional filing requirements. If, at any time, the FERC does not allow
this Agreement to function pursuant to the Tariff or requires any cost of
service support for any charges hereunder, Oglethorpe Power agrees to actively
support and pursue acceptance by the FERC of all charges and terms as stated in
this Agreement. If, at any time, the FERC orders any changes to any charges or
terms hereunder or any refunds, including, but not limited to, interest or
penalties, other than penalties resulting from actions by Georgia Power or its
agent that are not Prudent Utility Practices or that constitute willful
misconduct, Oglethorpe Power agrees that Georgia Power shall have the right to
file one or more unilateral changes to the charges and terms hereunder to
recover the revenues, as closely as practicable, intended by this Agreement in
its original form.

                  (b) Oglethorpe Power agrees to actively support any and all
such changes and to cooperate with and assist Georgia Power in securing
acceptance by the FERC of any and all such changes, in as expeditious a manner
as is practicable, to the extent such changes do not result in higher charges to
Oglethorpe Power than the charges intended by this Agreement in its original
form. The obligations pursuant to this Section 7.5 shall survive termination of
this Agreement and any of the Schedules.

                  (c) Georgia Power and Oglethorpe Power each agrees that,
except as expressly permitted under Sections 7.5, 7.6, 7.7, 8.4, 8.5, and 9.1 of
the Agreement, or to effectuate a change as permitted in Part 6 of each of the
Schedules, it shall not seek to modify this Agreement or any related Schedule
under Sections 205 or 206 of the Federal Power Act or any other 

                                       46
<PAGE>

provision of law, except with the consent of both Parties or as required to
comply with an order of a Governmental Authority with jurisdiction over this
Agreement.

         7.6      TERMINATION OF THE BPSA.

                  (a) It is the expressed intent of the Parties that the BPSA be
terminated effective with the commencement of service pursuant to Section 8.1 of
this Agreement. The Parties shall take all steps reasonably necessary to
terminate the BPSA including, but not limited to, the FERC's acknowledgment
thereof, without the necessity for any filings or other justifications for any
charges rendered under the BPSA.

                  (b) The Parties expressly agree that termination of the BPSA
pursuant to this Section 7.6 shall constitute expiration of the BPSA pursuant to
its own terms as contemplated under the Umbrella Agreement, Section 3.4.

         7.7      FERC MODIFICATION OF FORMULARY RATES UNDER THE BPSA. If, at 
any time, the FERC orders any changes to any charges rendered under the BPSA 
or any refunds, including, but not limited to, interest or penalties, other 
than penalties resulting from actions by Georgia Power or its agent that are 
not Prudent Utility Practices or that constitute willful misconduct, 
Oglethorpe Power agrees that Georgia Power shall have the right to file one 
or more unilateral changes to the charges and terms hereunder to recover the 
revenues, as closely as practicable, intended by the BPSA in its original 
form. Furthermore, Oglethorpe Power agrees to actively support any and all 
such changes and to cooperate with and assist Georgia Power in securing 
acceptance by the FERC of any and all such changes, in as expeditious a 
manner as is practicable, to the extent such changes do not result in higher 
charges to Oglethorpe Power than the charges intended by the BPSA in its 
original form. This obligation shall survive termination of this Agreement 
and any of the Schedules.

                                  ARTICLE VIII

                                TERM OF AGREEMENT

         8.1      TERM. The term of this Agreement shall begin on the date 
first written above and shall continue inclusive through one (1) minute after 
11:59 p.m. (Operating Time) on March 31, 2006. Service under this Agreement 
shall commence, subject to the conditions included in Section 8.2, at one (1) 
minute prior to 12:01 a.m. (Operating Time) on April 1, 1999. Oglethorpe 
Power shall have the option of terminating this Agreement, prior to 
commencement of service under this Agreement, by written notice delivered to 
Georgia Power by close of business on March 26, 1999, PROVIDED, HOWEVER, that 
Oglethorpe Power must provide evidence, acceptable in form and substance to 
Georgia Power, that the EMCs have not subscribed to at least fifty megawatts 
(50MW), in aggregate, of the LT Resources. The provisions of Article VI shall 
survive termination of this Agreement to the extent necessary to render final 
bills and permit auditing and resolution of disputes, if any, with respect to 
such final bills in accordance with the provisions of Article VI.

         8.2      CONDITIONS FOR EFFECTIVENESS. The respective obligations 
hereunder of Georgia Power to sell capacity and energy to Oglethorpe Power, 
and of Oglethorpe Power to purchase capacity and energy from Georgia Power, 
are conditioned upon:

                  (1) The receipt by Georgia Power of acceptance by the FERC of
         this Agreement, without modification, as a service agreement pursuant
         to the Tariff.

                  (2) The receipt by Georgia Power of acceptance by the FERC of
         termination of the BPSA, without modification, effective with the
         commencement of service pursuant to this Agreement.

                                       48
<PAGE>

                  (3) If a Governmental Authority other than FERC properly
         asserts jurisdiction regarding approval of this Agreement, the receipt
         of any required approvals of this Agreement, without modification by
         such Governmental Authority.

                  (4) For the LT Resources, the receipt by Oglethorpe Power of
         approval by at least seventy-five percent (75%) of its board of
         directors and approval by at least seventy-five percent (75%) of its
         EMCs of this Agreement.

Georgia Power and Oglethorpe Power shall cooperate with each other, as the other
may reasonably request, in connection with the procurement of such acceptance
from the FERC and any required approvals of any Governmental Authorities.

         8.3      EMCS' APPROVAL OF ANY LT RESOURCE AS A NON-RECOURSE RESOURCE.

                  (a) If condition (4) of Section 8.2 is not met for any of the
LT Resources, but the EMCs approve said LT Resource(s) as a Non-Recourse
Resource (as such term is defined in Section 8.3(c) herein), the Parties agree
to amend this Agreement, as necessary, to obtain approval of such Non-Recourse
Resource by Oglethorpe Power and its approving members on or before June 30,
1999. Oglethorpe Power and its approving members shall execute separate
definitive agreements for the resale of capacity and energy purchased by
Oglethorpe Power under the amended Agreement as a Non-Recourse Resource and
further, in the case of those approving members who are borrowers from the RUS,
obtain approval by the RUS of such members' agreements with Oglethorpe Power on
or before June 30, 1999. If any LT Resource is approved as a Non-Recourse
Resource, the amended Agreement shall include a provision that there is no
recourse for Oglethorpe Power's monetary obligations under the amended Agreement
with respect to such Non-Recourse Resource, directly or indirectly, to the
general credit of Oglethorpe Power or to any property, revenues or agreements of
Oglethorpe Power, other than the revenues 

                                       49
<PAGE>

received by Oglethorpe Power under its separate contracts with its members who
have subscribed for the resale of energy and capacity from the Non-Recourse
Resource. If any LT Resource is approved as a Non-Recourse Resource, then, with
respect to that Non-Recourse Resource only, the approving members shall execute
additional agreements, as reasonably required, directly with Georgia Power for
their respective purchases, or shall guarantee Oglethorpe Power's obligations,
and shall provide such credit assurance as Georgia Power may reasonably require.
One or more of such approving members may contract directly with Georgia Power
concerning such Non-Recourse Resource similar to the LT Resource described in
this Agreement on such terms as the parties may mutually agree.

                  (b) In the event that either of the LT Resources is approved
as a Non-Recourse Resource, the effective date for commencement of service with
respect to such Non-Recourse Resource shall be July 1, 1999, and the term for
such Non-Recourse Resource shall be reduced by 3 Months, (i.e., the termination
dates will be unchanged). Furthermore, if the LT Peaking Resource is a
Non-Recourse Resource, its Monthly Capacity Rate for the period July 1, 1999,
through March 31, 2000, shall be three and twenty-five one-hundredths dollars
per kilowatt-month ($3.25/kW-Mo), and if the LT Steam Resource is a Non-Recourse
Resource, its Monthly Capacity Rate for the period July 1, 1999, through March
31, 2000, shall be four and fifty one-hundredths dollars per kilowatt-month
($4.50/kW-Mo).

                  (c) "Non-Recourse Resource" means an agreement for the
purchase of capacity and energy which is: approved by less than seventy-five
percent (75%) of Oglethorpe Power's board of directors, approved by less than
seventy-five percent (75%) of Oglethorpe Power's members, fully subscribed by
the subset of Oglethorpe Power's members who are approving 

                                       50
<PAGE>

members, and supported only by the credit of and revenues from sales to such
approving members, with no recourse to the general credit or other property of
Oglethorpe Power and its members.

         8.4      FERC CHANGES; RIGHTS TO TERMINATE.

                  Either Georgia Power or Oglethorpe Power may terminate this
Agreement, in its respective sole discretion, following the issuance of a final
unappealed order by the FERC or any other final action by any Governmental
Authority properly asserting jurisdiction over this Agreement either rejecting
this Agreement or accepting this Agreement in a modified form (so that this
Agreement is not in substantially the agreed-upon and filed form). Georgia Power
or Oglethorpe Power may elect to exercise such right to terminate only within
the thirty (30) Day period following the expiration of all periods within which
an appeal of such an Order could be filed by any person or entity. If Georgia
Power or Oglethorpe Power elects to exercise such right to terminate, then the
electing party shall deliver a written notice of such election to the other
within the aforementioned period, and this Agreement will be deemed to have been
terminated effective upon the date of the other's receipt of such written
notice.

         8.5      PURCHASES AFTER EXPIRATION, TERMINATION OR REDUCTION.

                  Oglethorpe Power agrees that this Agreement (and the capacity
and energy rates provided for herein and in the Schedules hereto) will expire at
each end of the Term and that this Agreement (and the capacity and energy rates
provided for herein and in the Schedules hereto) shall terminate effective as of
the date determined in accordance with Section 8.4 or 10.3, if such Section
becomes operative and is exercised by either Georgia Power or Oglethorpe Power.
Oglethorpe Power further agrees that it will not seek to purchase any capacity
or associated energy or to schedule any transactions under this Agreement after
the date of expiration or termination determined as aforesaid.

expiration of this Agreement or any termination of this Agreement on the date 
determined in accordance with Section 8.5 (which obligation of Oglethorpe

where Georgia Power's agent is given certain authorities hereunder) shall 
have any liability whatsoever for any party's performance, nonperformance or 
delay in 

                                       53

Georgia Power or Oglethorpe Power of any right or remedy shall not constitute a
waiver of its right to assert said right or remedy, at any time thereafter, or
any other rights or remedies available to it at the time of or any time after

                               SHORT TERM RESOURCE

         1.       GENERAL AND DEFINITIONS.

                  This Schedule A is attached to and incorporated into that
certain Long Term Transaction Service Agreement Under Southern Companies'
Federal Energy Regulatory Commission Electric Tariff Volume No. 4 Market-Based
Rate Tariff between Georgia Power Company and Oglethorpe Power Corporation (An

that Oglethorpe Power will pay for the capacity and energy associated with the
Short Term Resources on a Monthly basis utilizing the rates and methodologies
determined in accordance with this Schedule A. All initially capitalized terms
and phrases used in this Schedule A, but not expressly defined herein, shall
have the respective meanings ascribed to them in the Agreement.

         2.       CAPACITY AND TERM.

                  Georgia Power offers to sell to Oglethorpe Power, subject to
the terms of the Agreement, capacity and associated energy, from one (1) or more
of five (5) fifty megawatt (50 MW) Short Term Resources, designated "ST-1",
"ST-2", ST-3", "ST-4" and "ST-5", for the period commencing one (1) minute prior
to 12:01 a.m. (Operating Time) on June 1, 1999 and continuing through one (1)
minute after 11:59 p.m.(Operating Time) on May 31, 2000. Oglethorpe Power shall

                               Schedule A - page 1
<PAGE>

March 26, 1999. Such notice shall be incorporated herein by this reference. This
Schedule A shall terminate at one (1) minute after 11:59 p.m. (Operating Time)
on May 31, 2000.

         3.       MONTHLY CAPACITY CHARGE.

                  For each Short Term Resource purchased by Oglethorpe Power
pursuant to the notice incorporated above, Oglethorpe Power shall pay a Monthly
Capacity Charge, in dollars per Month ($/Mo), in accordance with the following
schedule:
<TABLE>
                <S>          <C>
                  June 1999 -- $362,500
                  July - September 1999  --  $662,500
                  October 1999 - May 2000  --  $75,000
</TABLE>

         4.       HOURLY ENERGY RATE.

                  (a) The Hourly Energy Rate for energy purchases associated
with the Short Term Resources shall be the product, expressed in dollars per
megawatt-hour rounded to the nearest one-hundredth ($0.00/MWH) of (i) one and
one-tenth (1.1) and (ii) Southern Marginal Cost, where Southern Marginal Cost is
defined as the incremental energy cost of Southern Dispatch after serving all
Southern Control Area obligations and actual Unit Power Sales' base, alternate,
supplemental and replacement schedules but prior to serving any other sales
outside the Southern Control Area, which costs shall include fuel expense,
variable operating and maintenance expense, fuel handling expense, emissions
allowance value, and other appropriate energy-related costs, including, but not
limited to, energy purchases, as permitted by the IIC and as determined prior to
the applicable Hour. The Hourly Energy Rate for energy utilization from "Excess
Short Term Resources" (as determined below) shall be increased by the
difference, if such difference is greater than zero (0), expressed in dollars
per megawatt-hour rounded to the nearest one-hundredth ($0.00),

                               Schedule A - page 2
<PAGE>

                  (1) the higher of (i) one and one tenth (1.1) times the
         highest Hourly (excluding multi-hour transactions) off-system
         transaction price disclosed by Georgia Power, if any, in effect for
         such Hour (either a purchase or a sale) or (ii) "System Marginal Cost"
         (as such term is defined and used in the RCSA) for such Hour plus ten
         dollars per megawatt-hour ($10/MWH), minus

                  (2) the sum, (i) the current Monthly Capacity Charge, in
         dollars per Month ($/Mo) for the Short Term Resources divided by the
         product of fifty megawatts (50 MW), the number of weekdays in such
         Month and sixteen (16) Hours per Day, plus (ii) one and one tenth (1.1)
         times the Southern Marginal Cost for such Hour.

Any off-system transaction price disclosed by Georgia Power shall be treated
consistently with the confidentiality provisions of Article XV of the RCSA.

                  (b) If the net of the "OPC Off-System Transactions," sales
plus exports minus purchases minus imports (as such term is defined and used in
the RCSA), is less than fifty megawatts (50 MW) during the Hour containing the
greatest "OPC Territorial Load" (as such term is defined and used in the RCSA)
during a given Day, then no Short Term Resources are deemed to be Excess Short
Term Resources during such Day. If the number of Short Term Resources scheduled
during the Hour containing the greatest OPC Territorial Load during a given Day
is less than the net OPC Off-System Transactions during such Hour, expressed in
megawatt-hours (MWH), divided by, fifty megawatts (50 MW), with any resulting
fraction being truncated to an integer value, then all of the Short Term
Resources are deemed to be Excess Short Term Resources during such Day.
Otherwise, the number of Short Term Resources that are not deemed to be Excess
Short Term Resources during a given Day equals (i) the number of Short Term
Resources scheduled during the Hour containing the greatest OPC Territorial
Load, 

                               Schedule A - page 3
<PAGE>

minus (ii) the net OPC Off-System Transactions during such Hour, expressed in
megawatt-hours (MWH), divided by, fifty megawatts (50 MW), with any resulting
fraction being truncated to an integer value. In any given Hour, Short Term
Resources that are not Excess Short Term Resources shall be deemed scheduled
first.

         5.       PERFORMANCE GUARANTEE.

                  If the provisions of Section 4.8(c) of the Agreement are 
         applicable for a given Month and the calculation detailed therein
         results in a value less than ninety-five one-hundredths (0.95), the
         credit due Oglethorpe Power in the following Monthly invoice shall be
         calculated as the product of (i) the difference between ninety-five
         one-hundredths (0.95) and the value calculated pursuant to Section
         4.8(c) of the Agreement expressed to three (3) decimal places, times
         (ii) the sum of the kilowatt (kW) capacity associated with the Short
         Term Resources purchased by Oglethorpe Power pursuant to the notice
         incorporated above, times (iii) if such Month is June, July, August or
         September, thirteen and twenty-five one-hundredths dollars per kilowatt
         ($13.25/kW), otherwise, one and fifty one-hundredths dollars per
         kilowatt ($1.50/kW).

         6.       CHANGE IN LAW.

                  The Parties acknowledge that a Change in Law, including, but
not limited to, environmental laws and regulations and energy taxes applicable
to wholesale sales, but specifically excluding any other taxes, may
significantly change (increase or decrease) Georgia Power's costs in providing
the service described above. In the event of such a Change in Law, either Party
may give notice to the other Party that Georgia Power's costs have changed
significantly and may initiate negotiations to modify this Schedule to reflect
such changes in costs. If the Parties have not negotiated and agreed upon an
amendment to this Schedule within 

                               Schedule A - page 4
<PAGE>

90 Days, either Party shall have the right to initiate a dispute resolution
process as follows: (i) Georgia Power shall make a good faith calculation of the
effect of such change and adjust the billing accordingly, (ii) Oglethorpe may
pay under protest, (iii) a mutually agreeable individual ("Accountant") shall
calculate the appropriate adjustment to reflect the change in cost, and billings
will be adjusted accordingly, and (iv) the Parties shall split Accountant's fee
for rendering such service. If the Parties cannot reach agreement on a mutually
agreeable individual, then the head of the utilities practice group at Arthur
Andersen will be used.

                  (i)  the megawatts (MW) purchased by Oglethorpe Power pursuant
                       to the notice incorporated above

                  (ii) for the Months of June, July and August, 0.92 for all
                       other Months, 0.84

         (2)  divided by the sum of:

              (a) the then current megawatts (MW) associated with the Remainder

              (b) the megawatts (MW) purchased by Oglethorpe Power pursuant to
         the notice incorporated above. 

         6.       CHANGE IN LAW.

                  The Parties acknowledge that a Change in Law, including, but
not limited to, environmental laws and regulations and energy taxes applicable
to wholesale sales, but specifically excluding any other taxes, may
significantly change (increase or decrease) Georgia Power's costs in providing
the service described above. In the event of such a Change in Law, either Party
may give notice to the other Party that Georgia Power's costs have changed
significantly and may initiate negotiations to modify this Schedule to reflect
such changes in costs. If the Parties have not negotiated and agreed upon an
amendment to this Schedule within 90 Days, either Party shall have the right to
initiate a dispute resolution process as follows: (i) Georgia Power shall make a
good faith calculation of the effect of such change and adjust the billing
accordingly, (ii) Oglethorpe may pay under protest, (iii) a mutually agreeable
individual ("Accountant") shall calculate the appropriate adjustment to reflect
the change in cost, and billings will be adjusted accordingly, and (iv) the
Parties shall split Accountant's fee for rendering such service. If the Parties
cannot reach agreement on a mutually agreeable individual, then the head of the
utilities practice group at Arthur Andersen will be used.
