ITEM 1. BUSINESS
 
                          OGLETHORPE POWER CORPORATION
 
GENERAL
 
    Oglethorpe Power Corporation (An Electric Membership Corporation)
("Oglethorpe") is a Georgia electric membership corporation incorporated in 1974
and headquartered in metropolitan Atlanta. Oglethorpe is owned by 39 retail
electric distribution cooperative members (the "Members"), who, in turn, are
owned by their retail consumers. Oglethorpe is the largest electric cooperative
in the United States in terms of operating revenues, assets, kWh sales and,
through the Members, consumers served. Oglethorpe and its subsidiary,
EnerVision, Inc., Tailored Energy Solutions ("EnerVision"), have approximately
170 employees.
 
    As with cooperatives generally, Oglethorpe operates on a not-for-profit
basis. Oglethorpe's principal business is providing wholesale electric power to
the Members. (See "Power Supply Business" herein.) The Members are local
consumer-owned distribution cooperatives providing retail electric service on a
not-for-profit basis. In general, the customer base of the Members consists of
residential, commercial and industrial consumers within specific geographic
areas. The Members serve approximately 1.2 million electric consumers (meters)
representing approximately 2.8 million people. For information on the Members,
see "THE MEMBERS."
 
    Oglethorpe's mailing address is 2100 East Exchange Place, Post Office Box
1349, Tucker, Georgia 30085-1349, and its telephone number is (770) 270-7600.
 
COOPERATIVE PRINCIPLES
 
    Cooperatives like Oglethorpe are business organizations owned by their
members, which are also either their wholesale or retail customers. As
not-for-profit organizations, cooperatives are intended to provide services to
their members at the lowest possible cost, in part by eliminating the need to
produce profits or a return on equity. Cooperatives may make sales to
non-members, the effect of which is generally to reduce costs to members. Today,
cooperatives operate throughout the United States in such diverse areas as
utilities, agriculture, irrigation, insurance and credit.
 
    All cooperatives are based on similar business principles and legal
foundations. Generally, an electric cooperative designs its rates to recover its
cost-of-service and plans to collect a reasonable amount of revenues in excess
of expenses (i.e., margins) to increase its patronage capital, which is the
equity component of its capitalization. Any such margins, which are considered
capital contributions (i.e., equity) from the members, are held for the accounts
of the members and returned to them when the board of directors of the
cooperative deems it prudent to do so. The timing and amount of any actual
return of capital to the members depends on the financial goals of the
cooperative and the cooperative's loan and security agreements.
 
CORPORATE RESTRUCTURING
 
    Oglethorpe and the Members completed a corporate restructuring (the
"Corporate Restructuring") on March 11, 1997, in which Oglethorpe was divided
into three specialized operating companies to respond to increasing competition
and regulatory changes in the electric industry. Oglethorpe's transmission
business was sold to and is now owned and operated by Georgia Transmission
Corporation (An Electric Membership Corporation) ("GTC"), a Georgia electric
membership corporation formed for that purpose. Oglethorpe's system operations
business was sold to and is now owned and operated by Georgia System Operations
Corporation ("GSOC"), a Georgia nonprofit corporation formed for that purpose.
 
                                       1

Oglethorpe and the 39 Members are the owners and members of GTC. Oglethorpe, the
39 Members and GTC are the owners and members of GSOC.
 
    GTC purchased the transmission business for an appraised fair market value
purchase price of approximately $709 million. The purchase price was paid
primarily by GTC's assumption of a portion (approximately 16.86%) of
Oglethorpe's long-term secured debt in an amount equal to approximately $686
million. Approximately $541 million of this debt (payable to the Rural Utilities
Service ("RUS"), the Federal Financing Bank ("FFB") and CoBank, ACB ("CoBank"))
became the sole obligation of GTC, and Oglethorpe was released from all
liability with regard to this debt. The remaining $145 million of debt assumed
by GTC relates to Oglethorpe's pollution control revenue bonds ("PCBs"). While
GTC assumed and agreed to pay this $145 million of debt, Oglethorpe was not
legally released from its obligation to repay this debt. For financial reporting
purposes, this debt is not shown on Oglethorpe's balance sheet and is shown on
Oglethorpe's capitalization table as being assumed by GTC. (See "SELECTED
FINANCIAL DATA" in Item 6 and "FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA" in
Item 8). The remainder of the purchase price was paid by GTC from cash obtained
through a loan from National Rural Utilities Cooperative Finance Corporation
("CFC") and the assumption of approximately $2 million of other Oglethorpe
liabilities. Oglethorpe also made a special patronage capital distribution of
approximately $49 million to the Members which was used by the Members to
establish equity in and to provide initial working capital to GTC. GTC now
provides transmission services to the Members, Oglethorpe and third parties. GTC
succeeded to all of Oglethorpe's rights and obligations with respect to the
Integrated Transmission System ("ITS"). (See "Relationship with GTC" herein for
further discussion of the ITS.)
 
    The system operations business and assets sold to GSOC consist of the system
control center and related energy control and revenue metering systems
equipment. The purchase price totaled approximately $9.4 million and was paid by
(i) GSOC's assumption of Oglethorpe's obligations under an existing note held by
the RUS, (ii) delivery of a purchase money note payable to Oglethorpe, and (iii)
the assumption of certain other liabilities of Oglethorpe. GSOC now operates the
system control center and provides system operations services to the Members,
Oglethorpe and GTC.
 
    Oglethorpe continues to operate its power supply business and administer its
power purchase contracts. Oglethorpe retained all of its owned and leased
generation assets and, as of December 31, 1997, had total assets of
approximately $4.5 billion and total long-term debt of approximately $3.6
billion. (See "Power Supply Business" herein and "MEMBER REQUIREMENTS AND POWER
SUPPLY RESOURCES.")
 
    Effective with the Corporate Restructuring, the Members amended Oglethorpe's
Bylaws to implement a new governance structure with an 11-member board of
directors consisting of six directors elected from the Members, four independent
outside directors and Oglethorpe's President and Chief Executive Officer. This
smaller board replaced Oglethorpe's former 39-member board comprised of
directors nominated from and by each Member. (See "DIRECTORS AND EXECUTIVE
OFFICERS OF THE REGISTRANT" in Item 10 for further information.)
 
    Contemporaneously with the Corporate Restructuring, Oglethorpe replaced its
prior Consolidated Mortgage and Security Agreement, dated as of September 1,
1994, by and among Oglethorpe and the United States of America, acting through
the Administrator of the RUS, and certain other mortgagees (the "RUS Mortgage"),
with an Indenture, dated as of March 1, 1997, from Oglethorpe to SunTrust Bank,
Atlanta ("SunTrust"), as trustee (as supplemented, the "Mortgage Indenture"). As
did the RUS Mortgage, the Mortgage Indenture constitutes a lien on substantially
all of the owned tangible and certain intangible property of Oglethorpe. (See
"Electric Rates" herein and "MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
CONDITION AND RESULTS OF OPERATIONS--General--RATES AND FINANCIAL COVERAGE
REQUIREMENTS" in Item 7 for further discussion of the revenue requirements of
the Mortgage Indenture.)
 
                                       2

    Immediately after the Corporate Restructuring, Oglethorpe's corporate name
was changed from "Oglethorpe Power Corporation (An Electric Membership
Generation & Transmission Corporation)" to "Oglethorpe Power Corporation (An
Electric Membership Corporation)" to reflect that it no longer provides
transmission services.
 
    In connection with the Corporate Restructuring, Oglethorpe undertook to
remove the costs of its marketing services business from its general rates and
recover these costs on a fee-for-services basis beginning in 1998. To do so,
Oglethorpe created a subsidiary, EnerVision, to which it has transferred its
marketing services business, which includes 30 full-time and 13 part-time
employees. Further, all or part of this subsidiary may be sold to third parties.
Oglethorpe does not expect any of these potential actions to have a material
effect on its financial condition or results of operations.
 
POWER SUPPLY BUSINESS
 
    Oglethorpe provides wholesale electric service to the 39 Members pursuant to
long-term, take-or-pay Wholesale Power Contracts described herein that obligate
the Members on a joint and several basis to pay rates sufficient to pay all the
costs of owning and operating Oglethorpe's power supply business. (See
"Wholesale Power Contracts" herein.) Oglethorpe supplies capacity and energy to
the Members from a combination of owned and leased generating plants and power
purchased under long-term contracts with other power suppliers and power
marketers. GTC provides transmission services to the Members for delivery of the
Members' power purchases.
 
    Oglethorpe owns or leases undivided interests in thirteen generating units.
These units provide Oglethorpe with a total of 3,335 megawatts ("MW") of
nameplate capacity, consisting of 1,500.6 MW of coal-fired capacity, 1,185 MW of
nuclear-fueled capacity, 632.5 MW of pumped storage hydroelectric capacity, 14.8
MW of oil-fired combustion turbine capacity and 2.1 MW of conventional
hydroelectric capacity. Oglethorpe's generating units consist of 30% undivided
interests in the Edwin I. Hatch Plant ("Plant Hatch"), the Hal B. Wansley Plant
("Plant Wansley") and the Alvin W. Vogtle Plant ("Plant Vogtle"), a 60%
undivided interest in the Robert W. Scherer Unit No. 1 ("Scherer Unit No. 1"), a
60% undivided interest in the Robert W. Scherer Unit No. 2 ("Scherer Unit No.
2"), a 100% interest in the Tallassee Project at the Walter W. Harrison Dam
("Tallassee") and a 74.61% undivided interest in the Rocky Mountain Pumped
Storage Hydroelectric Facility ("Rocky Mountain"). Plant Hatch consists of two
nuclear-fueled units, with nameplate ratings of 810 MW and 820 MW, respectively.
Plant Wansley consists of two coal-fired units, each with a nameplate rating of
865 MW. Plant Wansley also includes a 49.2 MW oil-fired combustion turbine.
Plant Vogtle consists of two nuclear-fueled units, each with a nameplate rating
of 1,160 MW. Plant Scherer consists of four coal-fired units, each with a
nameplate rating of 818 MW, with Oglethorpe having an interest only in Scherer
Unit No. 1 and Scherer Unit No. 2. Tallassee is a conventional hydroelectric
facility with a nameplate rating of 2.1 MW. Rocky Mountain is a 3 unit pumped
storage hydroelectric facility with a nameplate rating of 847.8 MW. (See "MEMBER
REQUIREMENTS AND POWER SUPPLY RESOURCES--General" and "GENERATING
FACILITIES--General" in Item 2.")
 
    Participants in Plants Hatch, Wansley and Vogtle and Scherer Units No. 1 and
No. 2 also include the Municipal Electric Authority of Georgia ("MEAG"), the
City of Dalton ("Dalton") and Georgia Power Company ("GPC"). GPC serves as
operating agent for these units. GPC is also a participant in Rocky Mountain
which is operated by Oglethorpe.
 
    Oglethorpe utilizes long-term power marketer arrangements to reduce the cost
of power to the Members. Oglethorpe has entered into power marketer agreements
with LG&E Energy Marketing Inc. ("LEM") effective January 1, 1997, for
approximately 50% of the load requirements of the Members and with Morgan
Stanley Capital Group Inc. ("Morgan Stanley") effective May 1, 1997, with
respect to 50% of the forecasted load requirements of the Members. The LEM
agreements are based on the actual requirements of the Members during the
contract term, whereas the Morgan Stanley agreement represents
 
                                       3

a fixed supply obligation. Under these power marketer agreements, Oglethorpe
purchases energy at fixed prices covering a portion of the costs of energy to
its Members. LEM and Morgan Stanley, in turn, have certain rights to market
excess energy from the Oglethorpe system. All of Oglethorpe's existing
generating facilities and power purchase arrangements are available for use by
LEM and Morgan Stanley for the term of the respective agreements. Oglethorpe
continues to be responsible for all the costs of its system resources but
receives revenue from LEM and Morgan Stanley for the use of the resources. (See
"MEMBER REQUIREMENTS AND POWER SUPPLY RESOURCES--General" and "--Power Marketer
Arrangements.")
 
    Oglethorpe purchases a total of approximately 1,250 MW of power pursuant to
power purchase agreements with GPC, Big Rivers Electric Corporation ("Big
Rivers"), Entergy Power, Inc. ("EPI"), and Hartwell Energy Limited Partnership
("Hartwell"). Oglethorpe has also contracted to purchase 275 MW of peaking
capacity from Florida Power Corporation during the summer of 1998. (See "MEMBER
REQUIREMENTS AND POWER SUPPLY RESOURCES--Power Purchase and Sale Arrangements.")
 
WHOLESALE POWER CONTRACTS
 
    In connection with the Corporate Restructuring, Oglethorpe and each of the
Members entered into substantially similar Amended and Restated Wholesale Power
Contracts, dated August 1, 1996 (the "Wholesale Power Contracts"), each of which
extends through December 31, 2025. Each Wholesale Power Contract permits a
Member to take future incremental power requirements either from Oglethorpe or
other sources. Under its Wholesale Power Contract, a Member is unconditionally
obligated on an express "take-or-pay" basis for a fixed allocation of
Oglethorpe's costs for its existing generation and purchased power resources, as
well as the costs with respect to any future resources in which such Member
elects to participate. Each Wholesale Power Contract specifically provides that
the Member must make payments whether or not power is delivered and whether or
not a plant has been sold or is otherwise unavailable. Oglethorpe is obligated
to use its reasonable best efforts to operate, maintain and manage its resources
in accordance with prudent utility practices. The Wholesale Power Contracts
provide that Oglethorpe will be responsible for power supply planning, resource
procurement and sales of capacity and energy for Members unless a Member
notifies Oglethorpe that it does not want Oglethorpe to provide those services
to it.
 
    Each Member's cost responsibility under its Wholesale Power Contract is
based on agreed-upon fixed percentage capacity responsibilities ("PCRs"). PCRs
have been assigned for all of Oglethorpe's existing generation and purchased
power resources. PCRs for any future resource will be assigned only to Members
choosing to participate in that resource. The Wholesale Power Contracts provide
that each Member will be jointly and severally responsible for all costs and
expenses of all existing generation and purchased power resources, as well as
for any future resources (whether or not such Member has elected to participate
in such future resource) that are approved by 75% of Oglethorpe's Board of
Directors and 75% of the Members. For resources so approved in which less than
all Members participate, costs are shared first among the participating Members,
and if all participating Members default, each non-participating Member is
expressly obligated to pay a proportionate share of such default.
 
    The Wholesale Power Contracts contain covenants by each Member (i) to
establish, maintain and collect rates and charges for the service of its
electric system, and (ii) to conduct its business in a manner which will produce
revenues and receipts at least sufficient to enable the Member to pay to
Oglethorpe, when due, all amounts payable by the Member under its Wholesale
Power Contract and to pay any and all other amounts payable from, or which might
constitute a charge or a lien upon, the revenues and receipts derived from its
electric system, including all operation and maintenance expenses and the
principal of, premium, if any, and interest on all indebtedness related to the
Member's electric system.
 
    See "MEMBER REQUIREMENTS AND POWER SUPPLY RESOURCES" for a description of
the Members' demand and energy requirements and the related power supply
resources. See also

"MEMBER REQUIREMENTS AND POWER SUPPLY RESOURCES--Power Marketing
Arrangements--RELATED AGREEMENTS" regarding supplemental agreements to the
Wholesale Power Contracts relating to the power marketer agreements.
 
ELECTRIC RATES
 
    Each Member is required to pay Oglethorpe for capacity and energy furnished
under its Wholesale Power Contract in accordance with rates established by
Oglethorpe. Oglethorpe reviews its rates at such intervals as it deems
appropriate but is required to do so at least once every year. Oglethorpe is
required to revise its rates as necessary so that the revenues derived from such
rates, together with its revenues from all other sources, will be sufficient,
but only sufficient to pay all costs of its system, including operating and
maintenance costs, the cost of purchased power, the cost of transmission
services, and principal and interest on all indebtedness (including capital
lease obligations) of Oglethorpe, all costs associated with decommissioning or
otherwise retiring any generating facility, to provide for the establishment and
maintenance of reasonable reserves, and to enable Oglethorpe to comply with all
financial requirements under the Mortgage Indenture. (See "MANAGEMENT'S
DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS--General--RATES AND FINANCIAL COVERAGE REQUIREMENTS" in Item 7.)
 
    Under the Mortgage Indenture, Oglethorpe is required, subject to any
necessary regulatory approval, to establish and collect rates which are
reasonably expected, together with other revenues of Oglethorpe, to yield an MFI
Ratio described herein for each fiscal year equal to at least 1.10. Margins for
Interest ("MFI") is defined in the Mortgage Indenture to be the sum of net
margins of Oglethorpe (which includes revenues of Oglethorpe subject to refund
at a later date but excludes provisions for (i) non-recurring charges to income,
including the non-recoverability of assets or expenses, except to the extent
Oglethorpe determines to recover such charges in rates, and (ii) refunds of
revenues collected or accrued subject to refund) plus interest charges, whether
capitalized or expensed, on all indebtedness secured under the Mortgage
Indenture or by a lien equal or prior to the lien of the Mortgage Indenture,
including amortization of debt discount and expense or premium but excluding
interest charges on indebtedness assumed by GTC ("Interest Charges"), plus any
amount included in net margins for accruals for federal or state income taxes
imposed on income after deduction of interest expense. MFI takes into account
any item of net margin, loss, gain or expenditure of any affiliate or subsidiary
of Oglethorpe only if Oglethorpe has received such net margins or gains as a
dividend or other distribution from such affiliate or subsidiary or if
Oglethorpe has made a payment with respect to such losses or expenditures. "MFI
Ratio" is the ratio of MFI to total Interest Charges for a given period. (See
"MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS--General--RATES AND FINANCIAL COVERAGE REQUIREMENTS" in Item 7.)
 
    The formulary rate established by Oglethorpe in the rate schedule to the
Wholesale Power Contracts employs a rate methodology under which all categories
of costs are specifically separated as components of the formula to determine
Oglethorpe's revenue requirements. The rate schedule also implements the
responsibility for fixed costs assigned to each Member (i.e., the PCR). The
monthly charges for capacity and other non-energy charges are based on
Oglethorpe's annual budget. Such capacity and other non-energy charges may be
adjusted by the Board of Directors, if necessary, during the year through an
adjustment to the annual budget. Energy charges reflect the pass-through of
actual energy costs whether incurred from generation or purchased power
resources or under the power marketing arrangements.
 
    The rate schedule formula also includes a prior period adjustment ("PPA")
mechanism designed to ensure that Oglethorpe achieves the minimum 1.10 MFI
Ratio. Amounts, if any, by which Oglethorpe fails to achieve a minimum 1.10 MFI
Ratio would be accrued as of December 31 of the applicable year and collected
from the Members during the period April through December of the following year.
Amounts within a range from a 1.10 MFI Ratio to a 1.20 MFI Ratio are retained as
margins. Amounts, if any, by which Oglethorpe exceeds the maximum 1.20 MFI Ratio
would be charged against revenues as of
 
                                       5

December 31 of the applicable year and refunded to the Members during the period
April through December of the following year. The rate schedule formula is
intended to provide for the collection of revenues which, together with revenues
from all other sources, are equal to all costs and expenses recorded by
Oglethorpe, plus amounts necessary to achieve at least the minimum 1.10 MFI
Ratio.
 
    Under the terms of Oglethorpe's prior RUS Mortgage, all rate revisions by
Oglethorpe were subject to the approval of RUS. Under the Mortgage Indenture and
related loan contract with RUS, however, adjustments to Oglethorpe's rates to
reflect changes in Oglethorpe's budgets are not subject to RUS approval, except
for any reduction in rates in a fiscal year following a fiscal year in which
Oglethorpe has failed to meet the minimum 1.10 MFI Ratio set forth in the
Mortgage Indenture. Changes to the rate schedule under the Wholesale Power
Contracts are subject to RUS approval. Oglethorpe's rates are not subject to the
approval of any other federal or state agency or authority, including the
Georgia Public Service Commission (the "GPSC").
 
    For information regarding future rates, see "MANAGEMENT'S DISCUSSION AND
ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS--General--RATES AND
FINANCIAL COVERAGE REQUIREMENTS" in Item 7.
 
RELATIONSHIP WITH GTC
 
    Oglethorpe and the 39 Members are members of GTC. GTC provides transmission
services to the Members for delivery of the Members' power purchases from
Oglethorpe, Southeastern Power Administration ("SEPA") and any other power
suppliers. GTC also provides transmission services to Oglethorpe and third
parties. Oglethorpe has entered into a transmission agreement with GTC to
provide transmission services for third party transactions and for service to
Oglethorpe's headquarters and the administration building at Rocky Mountain.
 
    GTC and the Members have entered into Member Transmission Service Agreements
(the "Member Transmission Agreements") under which GTC provides transmission
service to the Members pursuant to a transmission tariff. The Member
Transmission Agreements have a minimum term for network service for current load
until December 31, 2025. After an initial ten-year term, load growth above 1995
requirements may, with notice to GTC, be served by others. The Member
Transmission Agreements provide that if a Member elects to purchase a part of
its network service elsewhere, it must pay appropriate stranded costs to protect
the other Members from any rate increase that could otherwise occur. Under the
Member Transmission Agreements, Members have the right to design, construct and
own new distribution substations.
 
    The Member Transmission Agreements provide that the Members are responsible,
on a joint and several basis, for all of GTC's costs relating to its
transmission business. The Member Transmission Agreements contain express
covenants of the Members to set and collect retail rates sufficient to allow the
Members to meet their respective obligations under the Member Transmission
Agreements. The rate formula set forth in the transmission tariff is intended to
recover all costs and expenses paid or incurred by GTC. The rate expressly
includes in the description of costs to be recovered all principal and interest
on indebtedness of GTC (including any indebtedness of Oglethorpe assumed by
GTC). The rate further expressly provides for GTC to earn sufficient margins to
satisfy the requirements of its new mortgage indenture, which is substantially
similar to Oglethorpe's Mortgage Indenture.
 
    The GTC transmission tariff and associated Member Transmission Agreements
were developed to be consistent with federal transmission policy as expressed in
Order No. 888 of the Federal Energy Regulatory Commission ("FERC"). FERC's Order
No. 888 mandates open access to essentially all transmission systems in order to
promote competition in the bulk power markets and provides that non-regulated
utilities (such as Oglethorpe and GTC) must provide access to their transmission
systems on reciprocal terms and conditions in order to obtain transmission from
FERC-regulated utilities. The transmission tariff and Member Transmission
Agreements have been designed to facilitate the operation of GTC in the new
 
                                       6

regulatory environment and, accordingly, provide for GTC to serve on a
nondiscriminatory basis both member and non-member customers on terms intended
to meet FERC's reciprocity requirement. For information regarding a FERC filing
relating to GTC and Oglethorpe, see "LEGAL PROCEEDINGS" in Item 3.
 
    GTC owns approximately 2,400 miles of transmission line and approximately
460 substations of various voltages. In connection with the Corporate
Restructuring, GTC succeeded to Oglethorpe's rights in the ITS, which consists
of transmission facilities owned by GTC, GPC, MEAG and Dalton. Through
agreements, common access to the combined facilities that compose the ITS
enables the owners to use their combined resources to make deliveries to or for
their respective consumers, to provide transmission service to third parties and
to make off-system purchases and sales.
 
    GTC's rights and obligations with respect to the ITS are governed by the
Revised and Restated Integrated Transmission System Agreement with GPC (the
"ITSA"), which was assigned to GTC in connection with the Corporate
Restructuring. The ITSA provides for the transmission and distribution of
electric energy in the State of Georgia, other than in certain counties, and for
bulk power transactions, through use of the ITS. The ITS was established in
order to obtain the benefits of a coordinated development of the parties'
transmission facilities and to make it unnecessary for any party to construct
duplicative facilities. The ITS consists of all transmission facilities,
including land, owned by the parties on the date the ITSA became effective and
those thereafter acquired, which are located in the State of Georgia (other than
in the excluded counties) and which are used or usable to transmit power of a
certain minimum voltage and to transform power of a certain minimum voltage and
a certain minimum capacity (the "Transmission Facilities"). GPC has entered into
agreements with MEAG and Dalton that are substantially similar to the ITSA, and
GPC may enter into such agreements with other entities. The ITSA will remain in
effect through December 31, 2012 and, if not then terminated by five years'
prior written notice by either party, will continue until so terminated.
 
    The ITSA is administered by a committee (the "Joint Committee") composed of
two representatives from each of GTC, GPC, MEAG and Dalton. Each year, the Joint
Committee determines a four-year plan of additions to the Transmission
Facilities that will reflect the current and anticipated future transmission
requirements of the parties. Each ITS participant is generally required to
maintain an original cost investment in the Transmission Facilities in
proportion to their respective Peak Loads (as defined in the ITSA).
 
    GTC and GPC are parties to a Transmission Facilities Operation and
Maintenance Contract (the "Transmission Operation Contract"), under which GPC
provides System Operator Services (as defined in the Transmission Operation
Contract) for GTC. In addition, GPC is required to provide such supervision,
operation and maintenance supplies, spare parts, equipment and labor for the
operation, maintenance and construction of Transmission Facilities as may be
specified by GTC. GPC is also required to perform certain emergency work under
the Transmission Operation Contract. GTC is permitted, upon notice to GPC, to
perform, or contract with others for the performance of, certain services
performed by GPC. Absent termination or amendment of the Transmission Operation
Contract, however, GPC will continue to perform System Operator Services for
GTC. The term of the Transmission Operation Contract will continue from year to
year unless terminated by either party upon four years' notice. GTC is required
to pay its proportionate share of the cost for the services provided by GPC.
 
RELATIONSHIP WITH GSOC
 
    Oglethorpe, the 39 Members and GTC are members of GSOC. GSOC now owns and
operates the system control center and provides system operations services to
the Members, Oglethorpe and GTC. GTC has contracted with GSOC to provide certain
transmission system operation services including reliability monitoring,
switching operations, and the real-time management of the transmission system.
 
                                       7

RELATIONSHIP WITH GPC
 
    Oglethorpe's relationship with GPC is a significant factor in several
aspects of Oglethorpe's business. GPC is one of Oglethorpe's principal suppliers
of purchased power, and Oglethorpe is one of GPC's largest customers. All of
Oglethorpe's co-owned generating facilities, except Rocky Mountain, are operated
by GPC on behalf of itself as a co-owner and as agent for the other co-owners.
GPC and Oglethorpe, through the Members, are competitors in the State of Georgia
for electric service to new customers that have a choice of supplier under the
Georgia Territorial Electric Service Act, which was enacted in 1973 (the
"Territorial Act"). For further information regarding the relationships and
agreements with GPC, see "THE MEMBERS--Service Area and Competition," "MEMBER
REQUIREMENTS AND POWER SUPPLY RESOURCES--Power Purchase and Sale
Arrangements--POWER PURCHASES FROM GPC," "--Power Purchase and Sale
Arrangements--OTHER POWER PURCHASES," "GENERATING FACILITIES-- Fuel Supply" in
Item 2, "CO-OWNERS OF THE PLANTS AND THE PLANT AGREEMENTS--Co-Owners of the
Plants--GEORGIA POWER COMPANY" and "--The Plant Agreements" in Item 2.
 
RELATIONSHIP WITH RUS
 
    Historically, federal loan programs administered by RUS have provided the
principal source of financing for electric cooperatives. Loans guaranteed by RUS
and made by FFB have been a major source of funding for Oglethorpe. However, in
recent years, there have been legislative, administrative and budgetary
initiatives intended to reduce or, in some cases, eliminate federal funding for
electric cooperatives. In any event, Oglethorpe's management does not anticipate
the need for loans guaranteed by RUS well into the future. (See "MEMBER
REQUIREMENTS AND POWER SUPPLY RESOURCES-- Power Marketer Arrangements" for a
discussion of the long-term power marketer arrangements.)
 
    In connection with the Corporate Restructuring, Oglethorpe replaced its RUS
Mortgage with the Mortgage Indenture, which, like the RUS Mortgage, constitutes
a lien on substantially all of the owned tangible and certain intangible
property of Oglethorpe. Oglethorpe also entered into a new loan contract with
RUS in connection with the Mortgage Indenture. Under the new loan contract, RUS
has retained approval rights over certain significant actions and arrangements,
including, without limitation, (i) significant additions to or dispositions of
system assets, (ii) significant power purchase and sale contracts, (iii) changes
to the Wholesale Power Contracts, including the rate schedule contained therein,
(iv) changes to plant ownership and operating agreements and (v) in limited
circumstances, issuance of additional secured debt. The extent of RUS's approval
rights under the new loan contract with Oglethorpe is substantially less than
the supervision and control RUS has traditionally exercised over borrowers under
its standard loan and security documentation. In addition, the Mortgage
Indenture improves Oglethorpe's ability to borrow funds in the public capital
markets. (See "THE MEMBERS--Members' Relationship with RUS" for a discussion of
the impact of changes in the RUS lending program on the Members.)
 
RELATIONSHIP WITH INTELLISOURCE
 
    In conjunction with the Corporate Restructuring and as a part of its
continuing efforts to reduce costs, effective February 1, 1997, Oglethorpe
implemented a business alliance with Intellisource, Inc., a national provider of
outsourcing services. Pursuant to an agreement with Intellisource, approximately
150 support services division employees of Oglethorpe in the areas of
accounting, auditing, communications, human resources, facility management,
purchasing, telecommunications and information technology became employees of
Intellisource. Oglethorpe, GTC and GSOC are key customers of Intellisource and
are being served on-site by the managers and employees of Oglethorpe's former
support services division.

                                  THE MEMBERS
 
SERVICE AREA AND COMPETITION
 
    The Members are listed below and include 39 of the 42 electric distribution
cooperatives in the State of Georgia.

    The Members serve approximately 1.2 million electric consumers (meters)
representing approximately 2.8 million people. The Members serve a region
covering approximately 40,000 square miles, which is approximately 70% of the
land area in the State of Georgia, encompassing 150 of the State's 159 counties.
Sales by the Members in 1997 amounted to approximately 20 million megawatt-hours
("MWh"), with approximately 72% to residential consumers, 26% to commercial and
industrial consumers and 2% to other consumers. The Members are the principal
suppliers for the power needs of rural Georgia. While the Members do not serve
any major cities, portions of their service territories are in close proximity
to urban areas and are experiencing substantial growth due to the expansion of
urban areas, including metropolitan Atlanta, into suburban areas and the growth
of suburban areas into neighboring rural areas. The Members have experienced
average annual compound growth rates from 1995 through 1997 of 6% in number of
consumers and 5% in MWh sales.
 
    The Territorial Act regulates the service rights of all retail electric
suppliers in the State of Georgia. Pursuant to the Territorial Act, the GPSC
assigned substantially all areas in the State to specified retail suppliers.
With limited exceptions, the Members have the exclusive right to provide retail
electric service in their respective territories, which are predominately
outside of the municipal limits existing at the time the Territorial Act was
enacted in 1973. The chief exception to this rule of exclusivity is that
electric suppliers may compete for most new retail loads of 900 kilowatts or
greater. The GPSC may reassign territory only if it determines that an electric
supplier has breached the tenets of public convenience and necessity. The GPSC
may transfer service for specific premises only if: (i) the GPSC determines,
after joint application of electric suppliers and proper notice and hearing,
that the public convenience and necessity require a transfer of service from one
electric supplier to another; or (ii) the GPSC finds, after proper notice and
hearing, that an electric supplier's service to a premise is not adequate or
dependable or that its rates, charges, service rules and regulations
unreasonably discriminate in favor of or against the consumer utilizing such
premises and the electric utility is unwilling or unable to comply with an order
from GPSC regarding such service.
 
    Since 1973, unlike in the electric utility industry in general, the
Territorial Act has allowed limited competition among electric utilities in
Georgia by allowing the owner of any new facility located outside of municipal
limits and having a connected demand upon initial full operation of 900
kilowatts or greater to receive electric service from the retail supplier of its
choice. The Members, with Oglethorpe's support, are
 
                                       9

actively engaged in competition with other retail electric suppliers for these
new commercial and industrial loads. The number of commercial and industrial
loads served by the Members continues to increase annually. 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.
 
    The electric utility industry in the United States is undergoing fundamental
change and is becoming increasingly competitive. (See "CERTAIN FACTORS AFFECTING
THE ELECTRIC UTILITY INDUSTRY--General" and "MANAGEMENT'S DISCUSSION AND
ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS--Competition" in Item
7.)
 
    From time to time, utilities are approached by other parties interested in
purchasing their systems. Some of the Members have been approached in the past
by third parties indicating an interest in purchasing their systems. The
Wholesale Power Contracts provide that a Member may not dissolve, liquidate or
otherwise wind up its affairs without Oglethorpe's approval. A Member may not
consolidate or merge with any person or reorganize or change the form of its
business organization from an electric membership corporation or sell, transfer,
lease or otherwise dispose of all or substantially all of its assets to any
person, whether in a single transaction or series of transactions, unless
either: (i) the transaction is approved by Oglethorpe or (ii) other specified
conditions are satisfied including, but not limited to, an assumption agreement
by the transferee, satisfactory to Oglethorpe, containing an assumption by the
transferee of the performance and observance of every covenant and condition of
the Member under the Wholesale Power Contract, and certifications of accountants
as to certain specified financial requirements of the transferee (taking into
account the transfer).
 
COOPERATIVE STRUCTURE
 
    The Members are cooperatives that operate their systems on a not-for-profit
basis. Accumulated margins derived after payment of operating expenses and
provision for depreciation constitute patronage capital of the consumers of the
Members. Refunds of accumulated patronage capital to the individual consumers
may be made from time to time subject to limitations contained in mortgages
between the Members and RUS or loan documents with other lenders. The RUS
mortgages generally prohibit such distributions unless, after any such
distribution, the Member's total equity will equal at least 40% (30% in the case
of Members, if any, that have the new form of RUS loan documents, discussed
below) of its total assets, except that distributions may be made of up to 25%
of the margins and patronage capital received by the Member in the preceding
year (provided that equity is at least 20% in the case of Members, if any, that
have the new form of RUS loan documents). (See "Members' Relationship with RUS"
herein.)
 
    Oglethorpe is a membership corporation, and the Members are not subsidiaries
of Oglethorpe. Except with respect to the obligations of the Members under each
Member's Wholesale Power Contract with Oglethorpe and Oglethorpe's rights under
such contracts to receive payment for power and energy supplied, Oglethorpe has
no legal interest in, or obligations in respect of, any of the assets,
liabilities, equity, revenues or margins of the Members. (See "OGLETHORPE POWER
CORPORATION-- Wholesale Power Contracts.") The revenues of the Members are not
pledged as security to Oglethorpe but are the source from which moneys are
derived by the Members to pay for power supplied by Oglethorpe under the
Wholesale Power Contracts. Revenues of the Members are, however, pledged under
their respective RUS mortgages or loan documents with other lenders.
 
RATE REGULATION OF MEMBERS
 
    Through provisions in the loan documents securing loans to the Members, RUS
exercises control and supervision over the rates for the sale of power of the
Members that borrow from it. The RUS mortgages of such Members require them to
design rates with a view to maintaining an average Times Interest
 
                                       10

Earned Ratio ("TIER") of not less than 1.50 and an average Debt Service Coverage
Ratio ("DSC") of not less than 1.25 for the two highest out of every three
successive years.
 
    Although the setting of the rates of the Members is not subject to approval
by any federal or state agency or authority other than RUS, the Territorial Act
prohibits the Members from unreasonable discrimination in the setting of rates,
charges, service rules or regulations and requires the Members to obtain GPSC
approval of long-term borrowings.
 
    Snapping Shoals EMC, Mitchell EMC, Troup EMC, Walton EMC and Cobb EMC have
prepaid their RUS indebtedness and are no longer RUS borrowers. Each of these
Members now has a rate covenant with its current lender. Other Members may also
pursue this option. To the extent that a Member who is not an RUS borrower
engages in wholesale sales or transmission in interstate commerce, it would be
subject to regulation by FERC under the Federal Power Act.
 
MEMBERS' RELATIONSHIP WITH RUS
 
    Through provisions in the loan documents securing loans to the Members, RUS
also exercises control and supervision over the Members that borrow from it in
such areas as accounting, borrowings, construction and acquisition of
facilities, and the purchase and sale of power.
 
    Historically, federal loan programs providing direct loans from RUS to
electric cooperatives have been a major source of funding for the Members.
However, in recent years, there have been legislative, administrative and
budgetary initiatives intended to reduce or, in some cases, eliminate federal
funding for electric cooperatives. In addition, the RUS loan and guarantee
programs have been characterized by the imposition of increasingly problematic
terms and conditions and extended delays in access to necessary funding. RUS has
adopted new standard forms of mortgages and loan contracts for distribution
borrowers the stated purpose of which is to update and modernize the loan and
security documentation employed by RUS. Distribution borrowers are required to
adopt these new forms as a condition to receiving new loans from RUS.
 
    Recent changes and proposals for further changes have made the direct loan
program administered by RUS more costly. The Rural Electrification Loan
Restructuring Act of 1993 eliminated the long-standing 5% loan program and
substituted a new program, the interest rates for which are based on rates being
paid on municipal bonds with comparable maturities. Certain borrowers with
either low consumer density or higher-than-average rates and lower-than-average
consumer income are still eligible for special loans at 5%. The President's
budget proposal for fiscal year 1999 includes a reduction under these loan
programs, and replacement with a new program with interest rates based on
Treasury rates. However, no legislation has yet been introduced to implement
this proposed program. The future cost, availability and amount of RUS direct
and guaranteed loans which may be available to the Members cannot be predicted.
 
MEMBERS' RELATIONSHIP WITH GTC AND GSOC
 
    For information about the Members' relationship with GTC and GSOC, see
"OGLETHORPE POWER CORPORATION--Relationship with GTC" and "--Relationship with
GSOC."
 
CONTRACTS WITH SEPA
 
    In addition to energy received from Oglethorpe under the Wholesale Power
Contracts, the Members purchase hydroelectric power under contracts with SEPA.
In 1997, the aggregate SEPA allocation to the Members was 523 MW plus associated
energy, representing approximately 10% of total Member peak demand and
approximately 5% of total Member energy requirements. New 20-year contracts
between each of the Members and SEPA have been executed, effective as of October
1, 1996. The provisions of the new contracts are essentially the same as the
existing contracts with a few exceptions. Each Member must schedule its energy
allocation, and each Member has designated Oglethorpe to perform this function.
 
                                       11

Pursuant to a separate agreement, Oglethorpe will schedule, through GSOC, the
Members' SEPA power deliveries. Further, each Member may be required, if certain
conditions are met, to contribute funds for capital improvements for Corps of
Engineers projects from which its allocation is derived in order to retain the
allocation. GTC delivers the Members' SEPA purchases under its network tariff
and contract with each Member. The new contracts are subject to RUS approval.
The amount of capacity and energy available from SEPA is not expected to
increase in an amount sufficient to serve a material portion of the projected
growth in the Members' requirements. (See "OGLETHORPE POWER
CORPORATION--Wholesale Power Contracts" and "MEMBER REQUIREMENTS AND POWER
SUPPLY RESOURCES--Member Demand and Energy Requirements" and the table
thereunder.)
 
    During 1996, legislative proposals were made that would have resulted in the
privatization of several of the federal power marketing administrations, in
particular SEPA. Ultimately, no proposal for the privatization of the power
marketing administrations was passed by Congress. The President's Budget for
fiscal year 1999 does not include any proposals to privatize the federal power
marketing administrations. The ultimate outcome of this issue in Congress cannot
be predicted with certainty.
 
                                       12

                 MEMBER REQUIREMENTS AND POWER SUPPLY RESOURCES
 
GENERAL
 
    Oglethorpe supplies capacity and energy to the Members from a combination of
owned and leased generating plants and from power purchased under long-term
contracts with other power suppliers and power marketers. Oglethorpe owns or
leases 3,335 MW of nameplate capacity, consisting of 1,500.6 MW of coal-fired
capacity, 1,185 MW of nuclear-fueled capacity, 632.5 MW of pumped storage
hydroelectric capacity, 14.8 MW of oil-fired combustion turbine capacity and 2.1
MW of conventional hydroelectric capacity. (See "GENERATING FACILITIES--General"
and "--Plant Performance" in Item 2 for a description of Oglethorpe's generating
facilities.) These resources are generally scheduled and dispatched so as to
minimize the operating cost of Oglethorpe's system. However, Oglethorpe has
entered into long-term arrangements with power marketers to better utilize its
resources to reduce the cost of capacity and energy delivered to the Members, in
part by giving certain dispatch rights to the power marketers. (See "Power
Marketer Arrangements" herein.)
 
MEMBER DEMAND AND ENERGY REQUIREMENTS
 
    The following table shows the aggregate peak demand and energy requirements
of the Members for the years 1995 through 1997, and also shows the amounts of
such requirements supplied by Oglethorpe and SEPA. From 1995 through 1997,
demand and energy requirements increased at an average annual compound growth
rate of 4.1% and 5.6%, respectively.

(1) System peak demand of the Members measured at the Members' delivery points
    (net of system losses).
 
(2) Includes purchased power. (See "Power Marketer Arrangements," "Power
    Purchase and Sale Arrangements--POWER PURCHASES FROM GPC" and "Power
    Purchase and Sale Arrangements--OTHER POWER PURCHASES" herein.)
 
(3) Supplied by SEPA through contracts with the Members. (See "THE
    MEMBERS--Contracts with SEPA.") Under the new SEPA contracts effective
    October 1, 1996, the SEPA capacity allocation has been reduced by
    approximately 3.7% for losses.
 
    In 1997, Cobb EMC and Jackson EMC accounted for approximately 12.9% and
11.8% of Oglethorpe's total revenues, respectively. None of the other Members
accounted for as much as 10% of Oglethorpe's total revenues in 1997. Due to
greater than average growth rates, certain of Oglethorpe's customers, including
its larger customers such as Cobb EMC and Jackson EMC, have historically
accounted for an increasing percentage of Oglethorpe's total revenues. However,
under the new Wholesale Power Contracts described above, a Member may choose to
supply all or a portion of its increased requirements with purchases from other
suppliers. Although the Members have contracted for significant portions of
their anticipated future needs by participating in Oglethorpe's power marketer
agreements, certain of the Members' future needs during the terms of the power
marketer agreements could still be purchased from other suppliers. (See "Power
Marketer Arrangements" herein.)
 
    SEASONAL VARIATIONS
 
    The demand for energy by the Members is influenced by seasonal weather
conditions. Historically, Oglethorpe's peak demand has occurred during the
months of June through August. (See "OGLETHORPE POWER CORPORATION--Electric
Rates.") Energy revenues track energy costs as they are incurred and also
fluctuate month to month. Capacity revenues reflect the recovery of Oglethorpe's
fixed
 
                                       13

costs, which do not vary significantly from month to month; therefore, capacity
charges are billed and capacity revenues are recognized in equal monthly
amounts.
 
POWER MARKETER ARRANGEMENTS
 
    In 1996, Oglethorpe began utilizing power marketer arrangements to reduce
the cost of power to the Members. During 1997, Oglethorpe entered into long-term
power marketer agreements with LEM for approximately 50% of the load
requirements of the Members and with Morgan Stanley with respect to 50% of the
Members' then forecasted load requirements. The LEM agreements are based on the
actual requirements of the Members during the contract term, whereas the Morgan
Stanley agreement represents a fixed supply obligation. Generally, these
arrangements reduce the cost of supplying power to the Members by limiting the
risk of unit availability, by providing a guaranteed benefit for the use of
excess resources and by providing future power needs at a fixed price. All of
Oglethorpe's existing generating facilities and power purchase arrangements are
available for use by LEM and Morgan Stanley for the term of the respective
agreements. Oglethorpe continues to be responsible for all of the costs of its
system resources but receives revenue, as described below, from LEM and Morgan
Stanley for the use of the resources.
 
    LEM AGREEMENTS
 
    Effective January 1, 1997, Oglethorpe entered into power marketer agreements
with LEM for 50% of the load requirements of the Members. Under the agreements,
LEM is obligated to deliver, and Oglethorpe is obligated to take, approximately
50% of the load requirements of the participating Members less the load
requirements for certain customers who have the right to choose electric
suppliers, plus 50% of the delivery obligations under Oglethorpe's existing firm
power off-system sale contracts. For certain smaller customer choice loads, LEM
is obligated to deliver, if Oglethorpe requests, 50% of the associated load
requirements. Oglethorpe has the option of purchasing the energy requirements
for any customer choice load from another supplier. Oglethorpe is obligated to
sell and LEM is obligated to buy 50% of the output of each participating
Member's PCR share of the "must run" units (primarily nuclear units). Oglethorpe
is also obligated to make available the same share of all other resources, which
LEM may schedule. LEM does not have the right to the output of upgrades to these
resources. LEM pays Oglethorpe the costs associated with the energy taken,
subject to certain adjustments. Oglethorpe must pay LEM a contractually
specified price for each MWh purchased.
 
    The LEM agreement relating to 37 of the 39 Members has a term extending
through 2011. With one year's notice, Oglethorpe has the right to terminate the
LEM agreement beginning in 2002. With 18 months' notice, LEM has the right to
terminate the LEM agreement beginning in 2005. The LEM agreement relating to the
other two Members has a term extending through 1999.
 
    LEM is a subsidiary of LG&E Energy Corp., a Kentucky corporation, which is a
diversified energy services holding company. LG&E Energy Corp. 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
Commission.
 
    MORGAN STANLEY AGREEMENT
 
    Effective May 1, 1997, Oglethorpe entered into a power marketer agreement
with Morgan Stanley with respect to 50% of the Members' then forecasted load
requirements. The agreement obligates Oglethorpe to purchase fixed quantities of
energy at fixed prices. Each Member selected a term for its obligation, as well
as the portion of its then forecasted requirements to be purchased as a fixed
quantity. Oglethorpe is obligated to sell and Morgan Stanley is obligated to buy
50% of the output, in contractually fixed amounts, of each Member's PCR share
(for the term and portion selected) of the "must run" units (primarily nuclear
units). Oglethorpe is also obligated to make available the same share of all
other
 
                                       14

resources, in contractually fixed amounts, which Morgan Stanley may schedule for
each 24-hour day. This schedule is set the day prior based on availability
limitations in the contract. Morgan Stanley pays a contractually fixed amount
each month and an amount for the scheduled energy based on contractually fixed
prices. The agreement has a term extending to March 31, 2005, but the purchases
for certain Members decline to zero prior to that date. Oglethorpe plans to
manage the portion of the system resources covered by the Morgan Stanley
agreement through scheduling and dispatching such resources. Oglethorpe will
also make purchases and sales to balance the fixed purchase obligation against
the actual requirements and to optimize the use of the resources after receiving
the daily schedule from Morgan Stanley.
 
    Morgan Stanley is a subsidiary of Morgan Stanley, Dean Witter, Discover &
Co., a diversified investment banking and financial services company. Morgan
Stanley, Dean Witter, Discover & Co. 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 Commission.
 
    RELATED AGREEMENTS
 
    Oglethorpe has contracted with GTC to provide available transmission
services to deliver to the border of the ITS any energy sold to LEM or Morgan
Stanley, as well as any other wholesale power purchase. Each Member will use its
Member Transmission Agreement for delivery of energy purchased by Oglethorpe
from LEM, Morgan Stanley and others.
 
    In connection with the LEM and Morgan Stanley arrangements, each Member has
entered into supplemental agreements to its Wholesale Power Contract. The
supplemental agreements are the vehicle through which Oglethorpe and the Members
assure that the Members receive the benefits of and support the obligations for
the power marketer arrangements under the Wholesale Power Contracts.
 
    Each Member has approved the agreements with LEM and Morgan Stanley as
"future resources" under the Wholesale Power Contracts. Accordingly, each Member
has a PCR for each of the LEM and Morgan Stanley agreements and all costs
incurred by Oglethorpe under such agreements are recovered from the Members
under the Wholesale Power Contracts on a joint and several basis. To this
extent, the Members have elected, under the Wholesale Power Contracts, to
purchase a substantial portion of their future requirements from Oglethorpe.
(See "--Future Power Resources" herein and "OGLETHORPE POWER
CORPORATION--Wholesale Power Contracts.")
 
POWER PURCHASE AND SALE ARRANGEMENTS
 
    POWER PURCHASES FROM GPC
 
    Oglethorpe purchases 750 MW of capacity and associated energy from GPC on a
take-or-pay basis under the Block Power Sale Agreement ("BPSA"), which extends
through December 31, 2003. The capacity purchases under the BPSA are from four
Component Blocks (as defined in the BPSA), composed of two Component Blocks of
250 MW each (coal-fired units) and two Component Blocks of 125 MW each
(combustion turbine units). The capacity in one or more Component Blocks may,
however, be less than the MW stated above, as the result of scheduled retirement
of units or retirements due to force majeure events. Although Oglethorpe may not
increase its capacity purchases under the BPSA, it may reduce or extend its
purchases of one or more Component Blocks upon proper notice to GPC. Oglethorpe
has given notice of its intent to reduce its purchases by two 250 MW Component
Blocks (coal-fired units) effective September 1, 1998 and September 1, 1999.
Also, pursuant to its long-term power marketer agreements with LEM, Oglethorpe
has committed to continue reducing its purchases from GPC as permitted under the
BPSA and thus will no longer purchase any energy under the BPSA effective
September 1, 2001. (See "Power Marketer Arrangements--LEM AGREEMENTS" herein for
a discussion of the LEM agreement.)
 
                                       15

    OTHER POWER PURCHASES
 
    Oglethorpe purchases 100 MW of capacity from each of EPI and Big Rivers,
under agreements extending through June and July 2002, respectively. The
availability of capacity under the EPI contract is dependent on the availability
of two specific generating units available to EPI. The Tennessee Valley
Authority ("TVA") provides the transmission service to deliver the power from
the Big Rivers electric system to the ITS. TVA and Southern Company Services, as
agent for Alabama Power Company and Mississippi Power Company, provide the
transmission service necessary to deliver the power from EPI to the ITS. (See
Note 9 of Notes to Financial Statements in Item 8.)
 
    Oglethorpe also has a contract through 2019 to purchase approximately 300 MW
of capacity from Hartwell, a partnership owned 50% by NGC Corporation and 50% by
American National Power, Inc., a subsidiary of National Power, PLC. This
capacity is provided by two 150 MW gas-fired turbine generating units on a site
near Hartwell, Georgia. Oglethorpe intends to use the units for peaking capacity
but has the right to dispatch the units fully. Prior to the merger of Destec
Energy, Inc. and NGC Corporation, Oglethorpe notified Hartwell that Oglethorpe's
rights under the power purchase agreement to consent to the merger or to
exercise its rights of first refusal to purchase equity interests in the
partnership would be triggered by the merger. Hartwell, however, refused to
recognize Oglethorpe's rights and the parties are seeking a court order to
clarify Oglethorpe's contractual rights with respect to the merger.
 
    In addition to the purchases from GPC, Big Rivers, EPI and Hartwell,
Oglethorpe also purchases small amounts of capacity and energy from "qualifying
facilities" under the Public Utility Regulatory Policies Act of 1978 ("PURPA").
Under a waiver order from FERC, Oglethorpe historically made all purchases the
Members would have otherwise been required to make under PURPA and Oglethorpe
was relieved of its obligation to sell certain services to "qualifying
facilities" so long as the Members make those sales. Oglethorpe historically
provided the Members with the necessary services to fulfill these sale
obligations. Purchases by Oglethorpe from such qualifying facilities provided
0.2% of Oglethorpe's energy requirements for the Members in 1997. As a result of
the Corporate Restructuring, the Members may make such purchases in the future
instead of Oglethorpe.
 
    Finally, Oglethorpe has contracted with Florida Power Corporation to
purchase 275 MW of peaking capacity during the summer of 1998.
 
    LONG-TERM POWER SALES
 
    Oglethorpe has an agreement to sell 100 MW of base capacity to Alabama
Electric Cooperative beginning June 1, 1998, and extending through December 31,
2005. During the term of the power marketer agreements, LEM and Morgan Stanley
will be responsible for supplying Oglethorpe with sufficient power to fulfill
these power sales.
 
    OTHER POWER SYSTEM ARRANGEMENTS
 
    Oglethorpe has interchange, transmission and/or short-term capacity and
energy purchase or sale agreements with over 60 utilities, power marketers and
other power suppliers. The agreements provide variously for the purchase and/or
sale of capacity and energy and/or for the purchase of transmission service. The
development of and access to the ITS and the interconnections with other
utilities are key elements in Oglethorpe's ability to make off-system sales and
purchases through its transmission contract with GTC and to compete in an
increasingly competitive market.
 
FUTURE POWER RESOURCES
 
    Under the Wholesale Power Contracts, Oglethorpe provides joint planning
services for all participating Members. A Member may elect not to have
Oglethorpe provide joint planning, procurement or bulk power marketing services.
Although the existing long-term power marketer arrangements with LEM and
 
                                       16

Morgan Stanley were designed to provide substantially all of the Members'
requirements during their contract terms, Oglethorpe will continue to offer
these planning services for requirements beyond the contract terms as well as
for evaluation of contract options and balancing of actual requirements against
fixed purchase obligations. Consequently, Oglethorpe has forecasted that peak
requirements for the Members will exceed contracted purchases over the next
several years and has issued a request for proposals for an aggregate of 100 MW
to 1,100 MW to supply these additional requirements. Oglethorpe has signed
contracts for an aggregate of 160 MW for delivery during the summer months of
1998, and may sign additional contracts up to 350 MW in the aggregate for supply
during that period. Oglethorpe is continuing to analyze proposals for deliveries
after 1998. All Members currently participate in joint planning.

            CERTAIN FACTORS AFFECTING THE ELECTRIC UTILITY INDUSTRY
 
GENERAL
 
    The electric utility industry has been and in the future will continue to be
affected by a number of factors which could have an impact on the financial
condition of an electric utility such as Oglethorpe. These factors likely would
affect individual utilities in different ways. Such factors include, among
others: (i) the transition to increasing competition in the generation of
electricity and the corresponding increase in competition from other suppliers
of electricity, (ii) fluctuations in the market price for electricity, (iii)
effects of compliance with changing environmental, licensing and regulatory
requirements, (iv) regulatory and other changes in national and state energy
policy, including open access transmission, (v) uncertain access to low cost
capital for replacement of aging fixed assets, (vi) increases in operating
costs, including the cost of fuel for the generation of electric energy, (vii)
uncertain recovery of the cost of existing facilities, (viii) fluctuations in
demand, including rates of load growth and changes in competitive market share,
(ix) unbundling of services and corresponding corporate and functional
restructurings by electric utility companies, and (x) the effects of
conservation and energy management on the use of electric energy. These factors
present an increasing challenge to companies in the electric utility industry,
including Oglethorpe and the Members, to reduce costs, improve the management of
resources and respond to the changing environment. (See "Environmental and Other
Regulation" herein, "OGLETHORPE POWER CORPORATION--Corporate Restructuring,"
"MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS--Competition" in Item 7, "MEMBER REQUIREMENTS AND POWER SUPPLY
RESOURCES--General" and "--Power Purchase and Sale Arrangements--OTHER POWER
PURCHASES.")
 
COMPETITION
 
    The electric utility industry in the United States is undergoing fundamental
change and is becoming increasingly competitive. (See "MANAGEMENT'S DISCUSSION
AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS--Competition" in
Item 7.)
 
ENVIRONMENTAL AND OTHER REGULATION
 
    GENERAL
 
    As is typical for electric utilities, Oglethorpe is subject to various
federal, state and local air and water quality requirements which, among other
things, regulate emissions of pollutants, such as particulate matter, sulfur
oxides and nitrogen oxides into the air and discharges of other pollutants,
including heat, into waters of the United States. Oglethorpe is also subject to
federal, state and local waste disposal requirements that regulate the manner of
transportation, storage and disposal of various types of waste.
 
    In general, environmental requirements are becoming increasingly stringent.
New requirements may substantially increase the cost of electric service, by
requiring changes in the design or operation of existing facilities or changes
or delays in the location, design, construction or operation of new facilities.
Failure to comply with these requirements could result in the imposition of
civil and criminal penalties as well as the complete shutdown of individual
generating units not in compliance. There is no assurance that Oglethorpe's
units will always remain subject to the regulations currently in effect or will
always be in compliance with future regulations.
 
    Compliance with environmental standards will continue to be reflected in
Oglethorpe's capital expenditures and operating costs. Based on the current
status of regulatory requirements, Oglethorpe does not anticipate that any
capital expenditures or operating expenses associated with its compliance with
current laws and regulations will have a material effect on its results of
operations or its financial
 
                                       18

condition. Oglethorpe's direct capital costs to achieve compliance with current
environmental requirements are expected to be minimal for 1998, 1999 and 2000.
As further discussed below, however, capital costs to achieve compliance with
potential future environmental requirements could be significant.
 
    CLEAN AIR ACT
 
    Environmental concerns of the public, the scientific community and Congress
have resulted in the enactment of legislation that has had and will continue to
have a significant impact on the electric utility industry. In particular, on
November 15, 1990, legislation was enacted (the "1990 Amendments") that
substantially revised the Clean Air Act. One of the principal purposes of the
1990 Amendments is to improve air quality by reducing the emissions of sulfur
dioxide and nitrogen oxides from affected utility units, which include the
coal-fired units that generate electric power at Plants Wansley and Scherer.
 
    These sulfur dioxide reductions are being imposed through a sulfur dioxide
emission allowance trading program. An emission allowance, which gives the
holder the authority to emit one ton of sulfur dioxide during a calendar year,
is transferable and can be bought, sold or banked for use in the years following
its issuance. Allowances are issued by the U.S. Environmental Protection Agency
("EPA") to impose limited reductions on certain affected units in Phase I
(1995-1999) and more stringent reductions on all affected units in Phase II
(after the year 1999). After 1999, aggregate emissions of sulfur dioxide from
all units subject to this program will be capped at 8.9 million tons per year.
Oglethorpe is now complying with this program by using lower-sulfur fuel at
Plant Wansley. After 1999, Oglethorpe could use a variety of options for
compliance at Plants Wansley and Scherer, including the use of emission
allowances (issued, banked or purchased, if needed), fuel-switching or
installation of flue gas desulfurization equipment.
 
    A number of recently finalized regulations, proposed regulations, petitions
and on-going studies could result in more stringent controls on all emissions,
including utility emissions. The most significant of these appear to be the
following. First, because nitrogen oxides are considered to be a precursor to
ozone, coupled with the fact that metropolitan Atlanta is classified as a
"serious nonattainment area" under the one hour ozone National Ambient Air
Quality Standards ("NAAQS"), EPA and the State of Georgia may impose further
limits on emissions of nitrogen oxides at Plants Wansley and/or Scherer. Second,
EPA has tightened the NAAQS for both ozone and particulate matter, an action
that could affect any source that emits nitrogen oxides and sulfur dioxide,
including utility units. Court challenges to both standards are now being made.
Third, EPA has issued a proposed regulation for the regional control of ozone
which, if implemented as proposed, could require substantial reductions in
nitrogen oxides emissions from Plants Wansley and Scherer. Fourth, EPA has
proposed a new regional haze program, an action that could affect any source
that emits nitrogen oxides or sulfur dioxide and that may contribute to the
degradation of visibility in mandatory federal Class I areas, including utility
units. Fifth, various Northeastern states have filed petitions under the Clean
Air Act asking EPA to set more stringent nitrogen oxides limits on sources that
are significantly contributing to ozone nonattainment in their own states.
Georgia was named in only one of these petitions. Sixth, although EPA has
decided not to impose a new NAAQS for sulfur dioxide, that decision has been
remanded (after appeal) to EPA for further rulemaking, so it is still possible
that a new short-term standard for sulfur dioxide could be established. Finally,
the 1990 Amendments require that several studies be conducted regarding the
health effects from power plant emissions of certain hazardous air pollutants.
These studies, which have now been completed, indicate that further research is
needed before decisions can be made on whether additional controls of utility
emissions of such pollutants are necessary.
 
    Depending on the final outcome of these developments, and the implementation
approach selected by EPA and the State of Georgia, significant capital
expenditures and increased operation expenses could be incurred by Oglethorpe
for the continued operation of Plants Wansley and/or Scherer. The power marketer
arrangements generally do not provide for the recovery from the power marketers
of increased environmental costs. (See "MEMBER REQUIREMENTS AND POWER SUPPLY
RESOURCES--
 
                                       19

Power Marketer Arrangements.") Because of the uncertainty associated with these
various developments, Oglethorpe cannot now predict the effect that any of these
potential requirements may have on the operations of Plants Wansley and/or
Scherer.
 
    Compliance with the requirements of the Clean Air Act may also require
increased capital or operating expenses on the part of GPC. Any increases in
GPC's capital or operating expenses may cause an increase in the cost of power
purchased from GPC. (See "MEMBER REQUIREMENTS AND POWER SUPPLY RESOURCES--Power
Purchase and Sale Arrangements--POWER PURCHASES FROM GPC.")
 
    NUCLEAR REGULATION
 
    Oglethorpe is subject to the provisions of the Atomic Energy Act of 1954, as
amended (the "Atomic Energy Act"), which vests jurisdiction in the Nuclear
Regulatory Commission ("NRC") over the construction and operation of nuclear
reactors, particularly with regard to certain public health, safety and
antitrust matters. The National Environmental Policy Act has been construed to
expand the jurisdiction of the NRC to consider the environmental impact of a
facility licensed under the Atomic Energy Act. Plants Hatch and Vogtle are being
operated under licenses issued by the NRC. All aspects of the operation and
maintenance of nuclear power plants are regulated by the NRC. From time to time,
new NRC regulations require changes in the design, operation and maintenance of
existing nuclear reactors. Operating licenses issued by the NRC are subject to
revocation, suspension or modification, and the operation of a nuclear unit may
be suspended if the NRC determines that the public interest, health or safety so
requires. The operating licenses issued for each unit of Plants Hatch and Vogtle
expire in 2014 and 2018 and 2027 and 2029, respectively.
 
    Pursuant to the Nuclear Waste Policy Act of 1982, as amended, the Federal
government has the regulatory responsibility for the final disposition of
commercially produced high-level radioactive waste materials, including spent
nuclear fuel. Such Act requires the owner of nuclear facilities to enter into
disposal contracts with the Department of Energy ("DOE") for such material.
These contracts require each such owner to pay a fee, which is currently one
dollar per MWh for the net electricity generated and sold by each of its
reactors. Oglethorpe is a party to agreements with DOE regarding Plants Hatch
and Vogtle. Plants Hatch and Vogtle currently have on-site spent fuel storage
capacity. Based on normal operations and retention of all spent fuel in the
reactor, it is anticipated that existing on-site pool capacity would be
sufficient until 2003 and 2008, respectively, to accept the number of spent fuel
assemblies that would normally be removed from the reactor during a refueling.
Contracts with the DOE have been executed to provide for the permanent disposal
of spent nuclear fuel produced at Plants Hatch and Vogtle. The services to be
provided by DOE were scheduled to begin in 1998; however, the DOE has stated
that permanent nuclear waste storage facilities are not available, and it is
uncertain when they will be available. If DOE does not begin receiving the spent
fuel from Plant Hatch in 2003 or from Plant Vogtle in 2008, alternative methods
of spent fuel storage will be needed. Activities for adding dry cask storage
capacity at Plant Hatch by 2000 are in progress. (See Note 1 of Notes to
Financial Statements regarding nuclear fuel cost in Item 8.)
 
    For information concerning nuclear insurance, see Note 8 of Notes to
Financial Statements in Item 8. For information regarding NRC's regulation
relating to decommissioning of nuclear facilities and regarding DOE's
assessments pursuant to the Energy Policy Act for decontamination and
decommissioning of nuclear fuel enrichment facilities, see Note 1 of Notes to
Financial Statements in Item 8.
 
    OTHER ENVIRONMENTAL REGULATION
 
    In 1993, EPA issued a ruling confirming the non-hazardous status of coal
ash. That ruling may apply, however, only to situations where those wastes are
not co-managed, I.E., not mixed with other wastes. Pursuant to court order, EPA
has until the Spring of 1999 to classify co-managed utility wastes as either
 
                                       20

hazardous or non-hazardous. If the wastes are classified as hazardous,
substantial additional costs for the management of such wastes might be required
of Oglethorpe, although the full impact would depend on the subsequent
development of requirements pertaining to these wastes.
 
    Oglethorpe is subject to other environmental statutes including, but not
limited to, the Clean Water Act, the Georgia Water Quality Control Act, the
Georgia Hazardous Site Response Act, the Toxic Substances Control Act, the
Resource Conservation & Recovery Act, the Endangered Species Act, the
Comprehensive Environmental Response, Compensation and Liability Act, the
Emergency Planning and Community Right to Know Act, and to the regulations
implementing these statutes. Oglethorpe does not believe that compliance with
these statutes and regulations will have a material impact on its financial
condition or results of operations. Changes to any of these laws, some of which
are being reviewed by Congress, could affect many areas of Oglethorpe's
operations. Although compliance with new environmental legislation could have a
significant impact on Oglethorpe, those impacts cannot be fully determined at
this time and would depend in part on the final legislation and the development
of implementing regulations.
 
    The scientific community, regulatory agencies and the electric utility
industry are continuing to examine the issues of global warming and the possible
health effects of electromagnetic fields. While no definitive scientific
conclusions have been reached, it is possible that new laws or regulations
pertaining to these matters could increase the capital and operating costs of
electric utilities, including Oglethorpe or entities from which Oglethorpe
purchases power. In addition, the potential for liability exists from lawsuits
that might be brought alleging damages from electromagnetic fields.
 
                               OTHER INFORMATION
 
    Information with respect to fuel supply for Oglethorpe's plants is set forth

ITEM 2. PROPERTIES
 
                             GENERATING FACILITIES
 
GENERAL
 
    The following table sets forth certain information with respect to the
generating facilities in which Oglethorpe currently has ownership or leasehold
interests, all of which are in commercial operation. Plant Hatch, Plant Wansley,
Plant Vogtle and Scherer Unit No. 1 and Scherer Unit No. 2 are co-owned by
Oglethorpe, GPC, MEAG and Dalton. GPC is the operating agent for each of these
co-owned plants. Rocky Mountain is co-owned by Oglethorpe and GPC, and
Oglethorpe is the operating agent. Oglethorpe is the sole owner of Tallassee.

(1) Equivalent Availability is a measure of the percentage of time that a unit
    was available to generate if called upon, adjusted for periods when the unit
    is partially derated from the "maximum dependable capacity" rating.
 
(2) Capacity Factor is a measure of the output of a unit as a percentage of the
    maximum output, based on the "maximum dependable capacity" rating, over the
    period of measure.
 
(3) Rocky Mountain Commercial Operation Dates: Unit 1--July 24, 1995; Unit
    2--June 19, 1995; Unit 3--June 1, 1995. This information was calculated
    beginning from the commercial operation date for each unit. As a pumped
    storage plant, Rocky Mountain primarily operates in peaking service.
 
    The nuclear refueling cycle for Plants Hatch and Vogtle exceeds twelve
months. Therefore, in some calendar years the units at these plants are not
taken out of service for refueling, resulting in higher levels of equivalent
availability and capacity factor.
 
FUEL SUPPLY
 
    COAL.  Coal for Plant Wansley is currently purchased under long-term
contracts and in spot market transactions. As of February 28, 1998, there was a
33-day coal supply at Plant Wansley based on nameplate rating.
 
    Low-sulfur "compliance" coal for Scherer Units No. 1 and No. 2 is purchased
under long-term contracts and in spot market transactions. As of February 28,
1998, the coal stockpile at Plant Scherer contained a 33-day supply based on
nameplate rating. During 1994, Plant Scherer was converted to burn both
sub-bituminous and bituminous coals, and a separate stockpile of sub-bituminous
coal was built in addition to the stockpile of bituminous coal.
 
    The Plant Scherer and Wansley ownership and operating agreements were
amended in 1993 and 1996, respectively, to allow each co-owner (i) to dispatch
separately its respective ownership interest in conjunction with contracting
separately for long-term coal purchases procured by GPC and (ii) to procure
separately long-term coal purchases. Pursuant to the amendments, Oglethorpe
implemented separate
 
                                       23

dispatch of Plant Scherer in 1994 and at Plant Wansley in May 1997. Oglethorpe
continues to use GPC as its agent for fuel procurement.
 
    To take advantage of these changes at Plants Scherer and Wansley, Oglethorpe
formed a wholly owned subsidiary, Black Diamond Energy, Inc., to acquire rail
cars. This subsidiary has purchased or leased approximately 300 rail cars.
Oglethorpe entered into an initial 15-year lease with this subsidiary which
obligates Oglethorpe to pay all of the ownership and operating expenses of the
subsidiary relating to the rail cars during the lease term.
 
    For information relating to the impact that the Clean Air Act will have on
Oglethorpe, see "CERTAIN FACTORS AFFECTING THE ELECTRIC UTILITY
INDUSTRY--Environmental and Other Regulations--CLEAN AIR ACT" in Item 1.
 
    NUCLEAR FUEL.  GPC, as operating agent, has the responsibility to procure
nuclear fuel for Plants Hatch and Vogtle. GPC has contracted with Southern
Nuclear Operating Company ("SONOPCO"), a subsidiary of The Southern Company
specializing in nuclear services, to operate these plants, including nuclear
fuel procurement. (See "CO-OWNERS OF THE PLANTS AND PLANT AGREEMENTS--The Plant
Agreements.") SONOPCO employs both spot purchases and long-term contracts to
satisfy nuclear fuel requirements. The nuclear fuel supply and related services
are expected to be adequate to satisfy current and future nuclear generation
requirements.

    GEORGIA POWER COMPANY
 
    GPC is a wholly owned subsidiary of The Southern Company, a registered
holding company under the Public Utility Holding Company Act, and is engaged
primarily in the generation and purchase of electric energy and the
transmission, distribution and sale of such energy within the State of Georgia
at retail in over 600 communities (including Athens, Atlanta, Augusta, Columbus,
Macon, Rome and Valdosta), as well as in rural areas, and at wholesale to
Oglethorpe, MEAG and three municipalities. GPC is the largest supplier of
electric energy in the State of Georgia. (See "OGLETHORPE POWER CORPORATION--
Relationship with GPC" in Item 1.) GPC 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 Commission.
 
    MUNICIPAL ELECTRIC AUTHORITY OF GEORGIA

THE PLANT AGREEMENTS
 
    HATCH, WANSLEY, VOGTLE AND SCHERER
 
    Oglethorpe's rights and obligations with respect to Plants Hatch, Wansley,
Vogtle and Scherer are contained in a number of contracts between Oglethorpe and
GPC and, in some instances, MEAG and Dalton. Oglethorpe is a party to four
Purchase and Ownership Participation Agreements ("Ownership Agreements") under
which it acquired from GPC a 30% undivided interest in each of Plants Hatch,
Wansley and Vogtle, a 60% undivided interest in Scherer Units No. 1 and No. 2
and a 30% undivided interest in those facilities at Plant Scherer intended to be
used in common by Scherer Units No. 1, No. 2, No. 3 and No. 4 (the "Scherer
Common Facilities"). Oglethorpe has also entered into four Operating Agreements
("Operating Agreements") relating to the operation and maintenance of Plants
Hatch, Wansley, Vogtle and Scherer, respectively. The Ownership Agreements and
Operating Agreements relating to Plants Hatch and Wansley are two-party
agreements between Oglethorpe and GPC. The Ownership Agreements and Operating
Agreements relating to Plants Vogtle and Scherer are agreements among
Oglethorpe, GPC, MEAG and Dalton. The parties to each Ownership Agreement and
Operating Agreement are referred to as "Participants" with respect to each such
agreement.
 
    SALE AND LEASEBACK TRANSACTIONS.  In 1985, in four transactions, Oglethorpe
sold its entire 60% undivided ownership interest in Scherer Unit No. 2 to four
separate owner trusts (the "Lessors") established by four different
institutional investors (the "Sale and Leaseback Transaction"). (See Note 4 of
Notes to Financial Statements in Item 8.) Oglethorpe retained all of its rights
and obligations as a Participant under the Ownership and Operating Agreements
relating to Scherer Unit No. 2 for the term of the leases. (In the following
discussion, references to Participants "owning" a specified percentage of
interests include Oglethorpe's rights as a deemed owner with respect to its
leased interests in Scherer Unit No. 2.)
 
    The Ownership Agreements appoint GPC as agent with sole authority and
responsibility for, among other things, the planning, licensing, design,
construction, renewal, addition, modification and disposal of Plants Hatch,
Vogtle, Wansley and Scherer Units No. 1 and No. 2 and the Scherer Common
Facilities. The Operating Agreements gives GPC, as agent, sole authority and
responsibility for the management, control, maintenance and operation of the
plant to which it relates and provides for the use of power and energy from such
plant and the sharing of the costs thereof by the parties thereto in accordance
with their respective interests therein. In performing its responsibilities
under the Ownership and Operating Agreements, GPC is required to comply with
prudent utility practices. GPC's liabilities with respect to its duties under
the Ownership and Operating Agreements are limited by the terms thereof.
 
    Under the Ownership Agreements, Oglethorpe is obligated to pay a percentage
of capital costs of the respective plants, as incurred, equal to the percentage
interest which it owns or leases at each plant. GPC has responsibility for
budgeting capital expenditures subject to, in the case of Scherer Units No. 1
and No. 2, certain limited rights of the Participants to disapprove capital
budgets proposed by GPC and to substitute alternative capital budgets and, in
the case of Plants Hatch and Vogtle, the right of any co-owner to disapprove
large discretionary capital improvements.
 
    In 1990, the co-owners of Plants Hatch and Vogtle entered into the Nuclear
Managing Board Agreement which amended the Plant Hatch and Plant Vogtle
Ownership and Operating Agreements, primarily with respect to GPC's reporting
requirements, but did not alter GPC's role as agent with respect to the nuclear
plants. In 1993, the co-owners entered into the Amended and Restated Nuclear
Managing Board Agreement (the "Amended and Restated NMBA") which provides for a
managing board (the "Nuclear Managing Board") to coordinate the implementation
and administration of the Plant Hatch and Plant Vogtle Ownership and Operating
Agreements, provides for increased rights for the co-owners regarding certain
decisions and allows GPC to contract with a third party for the operation of the
nuclear units. Upon approval in March 1997 by the NRC of GPC's application to
add SONOPCO to the operating
 
                                       26

license of each unit of Plants Hatch and Vogtle and designate SONOPCO as the
operator, the Nuclear Operating Agreement between GPC and SONOPCO, which the
co-owners had previously approved, became effective. In connection with the
amendments to the Plant Scherer Ownership and Operating Agreements, the
co-owners of Plant Scherer entered into the Plant Scherer Managing Board
Agreement which provides for a managing board (the "Plant Scherer Managing
Board") to coordinate the implementation and administration of the Plant Scherer
Ownership and Operating Agreements and provides for increased rights for the
co-owners regarding certain decisions, but does not alter GPC's role as agent
with respect to Plant Scherer.
 
    The Operating Agreements provide that Oglethorpe is entitled to a percentage
of the net capacity and net energy output of each plant or unit equal to its
percentage undivided interest owned or leased in such plant or unit. GPC, as
agent, schedules and dispatches Plants Hatch and Vogtle. Pursuant to amendments
to the plant agreements, Oglethorpe began separately dispatching its ownership
share of Scherer Units No. 1 and No. 2 in 1993 and of Plant Wansley in 1997.
(See "GENERATING FACILITIES--Fuel Supply.") Except as otherwise provided, each
party is responsible for a percentage of Operating Costs (as defined in the
Operating Agreements) and fuel costs of each plant or unit equal to the
percentage of its undivided interest which is owned or leased in such plant or
unit. For Scherer Units No. 1 and No. 2 and for Plant Wansley, each party will
be responsible for its fuel costs and for variable Operating Costs in proportion
to the net energy output for its ownership interest, while responsibility for
fixed Operating Costs will continue to be equal to the percentage undivided
ownership interest which is owned or leased in such unit. GPC is required to
furnish budgets for Operating Costs, fuel plans and scheduled maintenance plans
subject to, in the case of Scherer Units No. 1 and No. 2, certain limited rights
of the Participants to disapprove such budgets proposed by GPC and to substitute
alternative budgets. The Ownership Agreements and Operating Agreements provide
that, should a Participant fail to make any payment when due, among other
things, such nonpaying Participant's rights to output of capacity and energy
would be suspended.
 
    The Operating Agreement for Plant Hatch will remain in effect with respect
to Hatch Units No. 1 and No. 2 until 2009 and 2012, respectively. The Operating
Agreement for Plant Vogtle will remain in effect with respect to each unit at
Plant Vogtle until 2018. The Operating Agreement for Plant Wansley will remain
in effect with respect to Wansley Units No. 1 and No. 2 until 2016 and 2018,
respectively. The Operating Agreement for Scherer Units No. 1 and No. 2 will
remain in effect with respect to Scherer Units No. 1 and No. 2 until 2022 and
2024, respectively. Upon termination of each Operating Agreement, following any
extension agreed to by the parties, GPC will retain such powers as are necessary
in connection with the disposition of the property of the applicable plant, and
the rights and obligations of the parties shall continue with respect to actions
and expenses taken or incurred in connection with such disposition.
 
    ROCKY MOUNTAIN
 
    Oglethorpe's rights and obligations with respect to Rocky Mountain are
contained in several contracts between Oglethorpe and GPC, the co-owners of
Rocky Mountain (the "Co-Owners"). Pursuant to Rocky Mountain Pumped Storage
Hydroelectric Ownership Participation Agreement, by and between Oglethorpe and
GPC (the "Rocky Mountain Ownership Agreement"), Oglethorpe initially acquired a
3% undivided interest in Rocky Mountain which interest increased as Oglethorpe
expended funds to complete construction of Rocky Mountain. The final ownership
percentages for Rocky Mountain are Oglethorpe 74.61% and GPC 25.39%. In
connection with this acquisition, Oglethorpe and GPC also entered into the Rocky
Mountain Pumped Storage Hydroelectric Project Operating Agreement (the "Rocky
Mountain Operating Agreement").
 
    The Rocky Mountain Ownership Agreement appoints Oglethorpe as agent with
sole authority and responsibility for, among other things, the planning,
licensing, design, construction, operation, maintenance and disposal of Rocky
Mountain. The Rocky Mountain Operating Agreement gives Oglethorpe, as
 
                                       27

agent, sole authority and responsibility for the management, control,
maintenance and operation of Rocky Mountain.
 
    In general, each Co-Owner is responsible for payment of its respective
ownership share of all Operating Costs and Pumping Energy Costs (as defined in
the Rocky Mountain Operating Agreement) as well as costs incurred as the result
of any separate schedule or independent dispatch. A Co-Owner's share of net
available capacity and net energy is the same as its respective ownership
interest under the Rocky Mountain Ownership Agreement. Oglethorpe and GPC have
each elected to schedule separately their respective ownership interests. The
Rocky Mountain Operating Agreement will terminate in 2035. The Rocky Mountain
Ownership and Operating Agreements provide that, should a Co-Owner fail to make
any payment when due, among other things, such non-paying Co-Owner's rights to
output of capacity and energy or to exercise any other right of a Co-Owner would
be suspended until all amounts due, together with interests, had been paid. The
capacity and energy of a non-paying Co-Owner may be purchased by a paying
Co-Owner or sold to a third party.
 
    In late 1996 and early 1997, Oglethorpe completed lease transactions for its
74.61% undivided ownership interest in Rocky Mountain. Under the terms of these
transactions, Oglethorpe leased the facility to three institutional investors
for the useful life of the facility, who in turn leased it back to Oglethorpe
for a term of 30 years. Oglethorpe will continue to control and operate Rocky
Mountain during the leaseback term, and it will exercise its fixed price
purchase option at the end of the leaseback period so as to retain all other
rights of ownership with respect to the plant if it is advantageous for
Oglethorpe to exercise such option.
 
ITEM 3. LEGAL PROCEEDINGS
 
    On June 17, 1997, PECO Energy Company--Power Team ("PECO") filed an
application with FERC pursuant to Section 211 of the Federal Power Act
requesting FERC to compel Oglethorpe and/or GTC to provide PECO with 250 MW of
firm point-to-point transmission service from the TVA-ITS interface to the
Florida-ITS interface for an initial three-year period, with an automatic
roll-over provision. PECO also seeks $10,000 per day in penalties from
Oglethorpe and/or GTC, alleging bad faith and delays in negotiations. In their
response to FERC, GTC and Oglethorpe contend that they negotiated with PECO in
good faith, and thus there is no reasonable basis for imposing the penalties
sought by PECO. GTC also responded that it does not have firm "available
transfer capability" at the TVA-ITS interface to fulfill PECO's request, after
taking into account the need to protect system reliability, existing firm
commitments, and use of the TVA-ITS interface to serve "native load," in
accordance with North American Electric Reliability Council guidelines. In the
event GTC is ordered by FERC to provide the requested service, PECO would be
required to compensate GTC at rates set by FERC in the order. As a consequence
of any such order, power purchased by Oglethorpe for delivery through the
TVA-ITS interface would probably be curtailed (based on past operational
experience at that interface), and could result in higher purchased power cost
than would otherwise be the case. Although FERC transmission pricing policy is
designed to ensure that a transmission provider is fully compensated for the
cost of providing transmission service, potentially including opportunity cost,
there can be no assurance that rates ordered by FERC for service to PECO would
fully compensate GTC, Oglethorpe and the Members for the use of the transmission
system and for any resulting effect on reliability or increase in the cost of
power.
 
    Oglethorpe is a party to various other actions and proceedings incident to
its normal business. Liability in the event of final adverse determinations in
any of these matters is either covered by insurance or, in the opinion
Oglethorpe's management, after consultation with counsel, should not in the
aggregate have a material adverse effect on the financial position or results of
operations of Oglethorpe.

ITEM 6. SELECTED FINANCIAL DATA
 
    The following table presents selected historical financial data of
Oglethorpe. The financial data presented as of the end of and for each year in
the five-year period ended December 31, 1997, have been derived from the audited
financial statements of Oglethorpe. Due to the Corporate Restructuring, the
results of operations and financial condition reflect operations as a combined
power supply, transmission and system operations company through March 31, 1997,
and operations solely as a power supply company thereafter. These data should be
read in conjunction with the financial statements of Oglethorpe and the notes
thereto included in Item 8, "OGLETHORPE POWER CORPORATION-Corporate 
Restructuring" in Item 1 and "MANAGEMENT'S DISCUSSION AND ANALYSIS OF 
FINANCIAL CONDITION AND RESULTS OF OPERATIONS" in Item 7.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND 
        RESULTS OF OPERATIONS
 
GENERAL

  CORPORATE RESTRUCTURING
 
    Oglethorpe and the Members completed a corporate restructuring (the
"Corporate Restructuring") on March 11, 1997, in which Oglethorpe was divided
into three specialized operating companies to respond to increasing competition
and regulatory changes in the electric industry. As part of the Corporate
Restructuring, Oglethorpe's transmission business was sold to, and is now owned
and operated by, Georgia Transmission Corporation ("GTC"). Oglethorpe's system
operations business was sold to, and is now owned and operated by, Georgia
System Operations Corporation ("GSOC"). (See Note 11 of Notes to Financial
Statements.) Oglethorpe continues to own and operate its power supply business.
Oglethorpe retained all of its owned and leased generation assets. Oglethorpe
also continues to administer its power purchase contracts and, through a wholly
owned subsidiary, EnerVision, Inc., Tailored Energy Solutions ("EnerVision"),
provide marketing support functions to the Members.
 
  MARGINS AND PATRONAGE CAPITAL
 
    Oglethorpe operates on a not-for-profit basis and, accordingly, seeks only
to generate revenues sufficient to recover its cost of service and to generate
margins sufficient to establish reasonable reserves and meet certain financial
coverage requirements. Revenues in excess of current period costs in any year
are designated as net margin in Oglethorpe's statements of revenues and expenses
and patronage capital. Retained net margins are designated on Oglethorpe's
balance sheets as patronage capital, which is allocated to each of the Members
on the basis of its electricity purchases from Oglethorpe. Since its formation
in 1974, Oglethorpe has generated a positive net margin in each year.
Oglethorpe's equity ratio (patronage capital and membership fees divided by
total capitalization) increased from 7.5% at December 31, 1996 to 8.4% at
December 31, 1997.
 
    In connection with the Corporate Restructuring, Oglethorpe made a $49 
million special patronage capital distribution to the Members which was used 
by the Members to establish equity in and to provide initial working capital 
to GTC. This distribution was offset primarily by current year margins and 
resulted in a net decrease in patronage capital from $356 million at 
December 31, 1996, to $331 million at December 31, 1997.
 
    Patronage capital constitutes the principal equity of Oglethorpe.  Any 
distributions of patronage capital are subject to the discretion of the Board 
of Directors, subject to Indenture rerquirements. Under the Indenture, dated 
as of March 1, 1997, from Oglethorpe to SunTrust Bank, Atlanta, as trustee 
("Mortgage Indenture"), Oglethorpe is prohibited from making any distribution 
of patronage capital to the Members if, at the time thereof or after giving 
effect thereto, (i) an event of default exists under the Mortgage Indenture, 
(ii) Oglethorpe's equity as of the end of the immediately preceding fiscal 
quarter is less than 20% of Oglethorpe's total capitalization, or (iii) the 
aggregate amount expended for distributions on or after the date on which 
Oglethorpe's equity first reaches 20% of Oglethorpe's total capitalization 
exceeds 35% of Oglethorpe's aggregate net margins earned after such date. 
This last restriction, however, will not apply if, after giving effect to 
such distribution, Oglethorpe's equity as of the end of the immediately 
preceding fiscal quarter is not less than 30% of Oglethorpe's total 
capitalization.
 
  RATES AND REGULATION
 
    Pursuant to the Amended and Restated Wholesale Power Contracts between 
Oglethorpe and each of the Members dated as of August 1, 1996 ("Wholesale 
Power Contracts"), Oglethorpe is required to design capacity and energy rates 
that generate sufficient revenues to recover all costs as described in such 
contracts, to establish and maintain reasonable margins and to meet its 
financial coverage requirements. Oglethorpe reviews its capacity rates at 
least annually to ensure that its fixed costs are being adequately recovered 
and, if necessary, adjusts its rates to meet its net margin goals. 
Oglethorpe's energy rate is established to recover actual fuel and variable 
operations and maintenance costs.
 
    In 1995, Oglethorpe implemented two new capacity rate options in an effort
to provide greater flexibility to the Members. These options allocated fixed
costs using billing determinants of the current year. These rates produced
differing monthly amounts of capacity revenues throughout 1995 and introduced
some variability and uncertainty as to the level of revenues and margins to be
received. Due to extreme weather conditions and other factors, the 1995 rates
options produced $2.5 million of revenues in excess 

                                              30



of budgeted amounts. Such excess amounts were returned to the Members in 1996.
 
    Under a capacity rate mechanism effective throughout 1996, each Member was
responsible for an assigned share of fixed costs based on an agreed-upon
allocation. Under this approach, capacity costs were collected in equal monthly
amounts. This interim rate mechanism was extended through March 31, 1997 until a
new rate schedule became effective under the Wholesale Power Contracts on April
1, 1997, in connection with the Corporate Restructuring. This new rate schedule
implements on a long-term basis the assignment of responsibility for fixed
costs. The monthly charges for capacity and other non-energy charges are based
on a rate formula using the Oglethorpe budget. The Board of Directors may adjust
such capacity and other non-energy charges during the year through an adjustment
to the annual budget. Energy charges are based on actual energy costs, whether
incurred from generation or purchased power resources or under the power
marketing arrangements.
 
    Under the Mortgage Indenture, Oglethorpe is required, subject to any 
necessary regulatory approval, to establish and collect rates that are 
reasonably expected, together with other revenues of Oglethorpe, to yield a 
Margins for Interest ("MFI") Ratio for each fiscal year equal to at least 
1.10. The MFI Ratio is determined by dividing the sum of (i) Oglethorpe's net 
margins (after certain defined adjustments), (ii) Interest Charges and (iii) 
any amount included in net margins for accruals for federal or state income 
taxes by Interest Charges. The definition of MFI takes into account any item 
of net margin, loss, gain or expenditure of any affiliate or subsidiary of 
Oglethorpe only if Oglethorpe has received such net margins or gains as a 
dividend or other distribution from such affiliate or subsidiary or if 
Oglethorpe has made a payment with respect to such losses or expenditures.
 
    The rate schedule also includes a Prior Period Adjustment ("PPA") mechanism
designed to ensure that Oglethorpe achieves the minimum 1.10 MFI Ratio. Amounts,
if any, by which Oglethorpe fails to achieve a minimum 1.10 MFI Ratio would be
accrued as of December 31 of the applicable year and collected from the Members
during the period April through December of the following year. Amounts within a
range from a 1.10 MFI Ratio to a 1.20 MFI Ratio are retained as patronage
capital. Amounts, if any, by which Oglethorpe exceeds the maximum 1.20 MFI Ratio
would be charged against revenues as of December 31 of the applicable year and
refunded to the Members during the period April through December of the
following year. The rate schedule formula is intended to provide for the
collection of revenues which, together with revenues from all other sources, are
equal to all costs and expenses recorded by Oglethorpe, plus amounts necessary
to achieve at least the minimum 1.10 MFI Ratio.
 
    For 1997, Oglethorpe achieved an MFI Ratio of 1.10. For comparative purposes
only, the pro forma MFI Ratio for 1996 would have been 1.09.
 
    Under the terms of Oglethorpe's prior mortgage, all rate revisions by
Oglethorpe were subject to the approval of the Rural Utilities Service ("RUS").
Under the Mortgage Indenture and related loan contract with RUS, adjustments to
Oglethorpe's rates to reflect changes in Oglethorpe's budgets are not subject to
RUS approval, except for any reduction in rates in a fiscal year following a
fiscal year in which Oglethorpe has failed to meet the minimum 1.10 MFI Ratio
set forth in the Mortgage Indenture. Changes to the rate schedule under the
Wholesale Power Contracts are subject to RUS approval. Oglethorpe's rates are
not subject to the approval of any other federal or state agency or authority,
including the Georgia Public Service Commission.
 
    Prior to 1997, Oglethorpe utilized a Times Interest Earned Ratio ("TIER") as
the basis for establishing its annual net margin goal. Under Oglethorpe's prior
mortgage, Oglethorpe was required to implement rates that were designed to
maintain an annual TIER of not less than 1.05. Oglethorpe's Board of Directors
set an annual net margin goal to be the amount required to produce a TIER of
1.07 in 1995 and 1996, and such TIER was achieved in each year. In addition to
the TIER requirement under the prior mortgage, Oglethorpe was also required
under the prior mortgage to implement rates designed to maintain a Debt Service
Coverage Ratio ("DSC") of not less than 1.0 and an Annual Debt Service Coverage
Ratio ("ADSCR") of not less than 1.25. Oglethorpe always met or exceeded the
TIER, DSC and ADSCR requirements of the prior mortgage.
 
    TIER is determined by dividing the sum of Oglethorpe's net margin plus
interest on long-term debt (including interest charged to construction) by
Oglethorpe's interest on long-term debt (including interest charged to
construction). DSC is determined by dividing the sum of Oglethorpe's net margin
plus interest on long-term debt (including interest charged to construction)
plus depreciation and amortization (excluding amortization of nuclear fuel and
debt discount and expense) by Oglethorpe's interest and principal payable on
long-term debt (including interest charged to construction). ADSCR is determined
by dividing the sum of Oglethorpe's net margin plus interest on long-term debt
(excluding interest charged to construction) plus depreciation and 

                                              31



amortization (excluding amortization of nuclear fuel and debt discount and 
expense) by Oglethorpe's interest and principal payable on long-term debt 
secured under the prior mortgage (excluding interest charged to construction).
 
RESULTS OF OPERATIONS
 
  HISTORICAL FACTORS AFFECTING FINANCIAL PERFORMANCE
 
    Oglethorpe has utilized both long-term contractual arrangements with 
Georgia Power Company ("GPC") and a rate mechanism utilizing deferred margins 
to allow for a gradual absorption of costs of generating plants into rates 
over several years. As of May 31, 1995, Oglethorpe's Members have fully 
absorbed into rates responsibility for the cost of its ownership interests in 
Plant Vogtle Units No. 1 and No. 2, and as of December 31, 1996, Oglethorpe's 
Members have fully absorbed into rates the costs of Rocky Mountain, the last 
of Oglethorpe's generating plants to be placed into service.
 
    Contractual arrangements with GPC provided that Oglethorpe sell to GPC a
declining percentage of Oglethorpe's entitlement to the capacity and energy of
certain co-owned generating plants during the initial seven to ten years of
operation of such units (the "GPC Sell-back"). As of May 31, 1995, the GPC
Sell-back expired for all units.
 
    Prior to the completion of the first unit of Plant Vogtle in 1987,
Oglethorpe's Board of Directors implemented policies that resulted in the
gradual absorption of the costs of Plant Vogtle by the Members. In each of the
years 1985 through 1995, Oglethorpe exceeded its net margin goal. The Board
adopted resolutions in each of these years requiring that these excess margins
be retained and used to mitigate rate increases associated with Plant Vogtle
and, subsequently, with Rocky Mountain. In each year beginning with 1989, a
portion of these margins was returned to the Members through billing credits.
(See Note 1 of Notes to Financial Statements.) As of December 31, 1996, all
amounts previously retained have been returned to the Members and this rate
mechanism ended.
 
  POWER MARKETER ARRANGEMENTS
 
    Oglethorpe is utilizing long-term power marketer arrangements to reduce the
cost of power to the Members. Oglethorpe has entered into power marketer
agreements with LG&E Energy Marketing Inc. ("LEM") effective January 1, 1997,
for approximately 50% of the load requirements of the Members and with Morgan
Stanley Capital Group Inc. ("Morgan Stanley"), effective May 1, 1997, with
respect to 50% of the Members' then forecasted load requirements. The LEM
agreements are based on the actual requirements of the Members during the
contract term, whereas the Morgan Stanley agreement represents a fixed supply
obligation. Under these power marketer agreements, Oglethorpe purchases energy
at fixed prices covering a portion of the costs of energy to its Members. LEM
and Morgan Stanley, in turn, have certain rights to market excess energy from
the Oglethorpe system. All of Oglethorpe's existing generating facilities and
power purchase arrangements are available for use by LEM and Morgan Stanley for
the term of the respective agreements. Oglethorpe continues to be responsible
for all of the costs of its system resources but receives revenue from LEM and
Morgan Stanley for the use of the resources.
 
    Oglethorpe utilized short-term power marketer arrangements during 1996. The
initial agreement was with Enron Power Marketing, Inc. ("EPMI") and was in place
January through August. From September through December 1996, another power
marketer arrangement was utilized with Duke/Louis Dreyfus L.L.C. ("DLD"). Under
each of the agreements, the power marketer was required to provide to Oglethorpe
at a favorable fixed rate all the energy needed to meet the Members'
requirements and Oglethorpe was required to provide to the power marketer at
cost, subject to certain limitations, upon request, all energy available from
Oglethorpe's total power resources. Under both agreements, Oglethorpe continued
to operate the power supply system and continued to dispatch the generating
resources to ensure system reliability.
 
  CORPORATE RESTRUCTURING
 
    As a result of the Corporate Restructuring, the Statements of Revenues 
and Expenses for 1997 reflect operations as a combined power supply, 
transmission and system operations company through March 31, 1997, and 
operations solely as a power supply company thereafter. (See Note 11 of Notes 
to Financial Statements for a pro forma Statement of Revenues and Expenses 
for the year ended December 31, 1997). Although the Corporate Restructuring 
was completed on March 11, 1997, pursuant to the restructuring agreement 
among Oglethorpe, GTC and GSOC, all transmission-related and systems 
operations-related revenues were assigned to Oglethorpe, and all 
transmission-related and systems operations-related costs were paid or 
reimbursed by Oglethorpe during the period March 11, 1997 through March 31, 
1997.
 
    Decreases in operating revenues, power delivery expenses, depreciation and
amortization, taxes other than income taxes, operating margin and net interest
charges from 1996 to 1997 are primarily attributable to the Corporate
Restructuring.

                                              32



    OPERATING REVENUES

    SALES TO MEMBERS.  Revenues from Members are collected pursuant to the 
Wholesale Power Contracts and are a function of the demand for power by the 
Members' consumers and Oglethorpe's cost of service. Revenues from sales to 
Members decreased by 2.2% for 1997 compared to 1996 and decreased by 0.7% in 
1996 compared to 1995. For 1997 compared to 1996, four factors primarily 
contributed to the change in revenues. Two factors were the result of the 
Corporate Restructuring and affected comparability, as follows: (1) Member 
capacity revenues declined by approximately $75 million due to the transfer 
of the transmission and system operations businesses to GTC and GSOC in 
connection with the Corporate Restructuring; and (2) as discussed under 
"OTHER INCOME (EXPENSE)" herein, Member revenues for 1997 of approximately 
$19.5 million related to EnerVision were reflected in "Other Income" since 
these marketing support activities are no longer part of operations of the 
power supply business. In addition, revenues were significantly affected by 
two operational factors: (1) Member energy revenues increased by $80 million 
primarily because the short-term power marketer arrangements with DLD and 
EPMI allowed Oglethorpe to pass through significant savings during 1996 (see 
the discussion of purchased power under "OPERATING EXPENSES" herein); and (2) 
in August 1997, capacity revenues were reduced by a $4 million refund to the 
Members as a result of an interim budget adjustment to reflect higher than 
anticipated investment income.

    Revenues from Members for 1996 decreased compared to 1995 due to the 
pass-through of savings in energy costs, which more than offset higher 
capacity revenue requirements and the effect of increased amounts of energy 
sold (see the discussion of savings in purchased power costs under "OPERATING 
EXPENSES" herein). Member capacity revenues in 1996 and 1995 were also 
affected by additional fixed costs related to the commercial operation of 
Rocky Mountain beginning in June 1995.

    The energy portion of Member revenues per kilowatt-hour ("kWh") increased 
24.4% in 1997 compared to 1996 and declined 13.2% in 1996 compared to 1995. 
Actual energy costs are passed through to the Members such that energy 
revenues equal energy costs. The increase in 1997 resulted from the $80 
million increase in net energy costs discussed above. The decrease in 1996 
resulted from savings of approximately $32 million in energy costs (compared 
to budget) achieved under the power marketer arrangements in effect during 
1996.

    The following table summarizes the amounts of kWh sold to Members and 
revenues per kWh during each of the past three years:

- ------------------------
(1) Excludes revenues related to the transmission business effective 
    April 1, 1997.

    In spite of mild weather in 1997, kWh sales to Members increased by 4.3% 
compared to 1996 due to continued growth in the Member systems' service 
territories. Member sales increased 7.4% in 1996 also due to Member growth, 
despite a summer in which temperatures were lower than the prolonged hot 
weather in 1995.

    SALES TO NON-MEMBERS. Sales of electric services to non-Members were 
primarily from energy sales to other utilities and power marketers, and 
pursuant to contractual arrangements with GPC. The following table summarizes 
the amounts of non-Member revenues from these sources for the past three 
years:

    Revenues from sales to non-Members declined in 1997 compared to 1996 and 
in 1996 compared to 1995. Sales to other utilities in 1997 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 that 
is not scheduled by Morgan Stanley pursuant to its power marketer 
arrangements. EPMI and DLD initiated sales to other utilities in 1996. In 
1996, where the power marketer did not have a contractual relationship with 
the purchaser and Oglethorpe did, Oglethorpe recorded the sale and credited 
the revenues to the power marketer in its monthly billing. In 1995, 
Oglethorpe made these sales directly to other utilities.

    Under the LEM and Morgan Stanley power marketer arrangements, and 
previously, under the EPMI and DLD power marketer arrangements, sales to the 
power marketers represented the net energy trans-

                                             33




mitted on behalf of LEM, Morgan Stanley, EPMI and DLD off-system on a daily 
basis from Oglethorpe's total resources. Such energy was sold to LEM, EPMI 
and DLD 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.

    The third source of non-Member revenues was power supply arrangements 
with GPC. These revenues were derived, for the most part, from energy sales 
arising from dispatch situations whereby GPC caused co-owned coal-fired 
generating resources to be operated when Oglethorpe's system did not require 
all of its contractual entitlement to the generation. These revenues 
compensated Oglethorpe for its costs because, under the operating agreements 
(before the agreements were recently amended as discussed below), Oglethorpe 
was responsible for its share of fuel costs any time a unit operated. 
Revenues from sales of this type to GPC varied slightly in 1997 compared to 
1996 and were lower in 1996 compared to 1995. In 1996, the power marketers 
elected to retain more of the output from Plant Wansley than in 1995. 
Pursuant to the amendments to the Plant Wansley ownership and operating 
agreements, Oglethorpe elected to separately dispatch its ownership interest 
in Plant Wansley beginning May 1, 1997. Thereafter, Plant Wansley ceased to 
be a source of this type of sales transaction; therefore, this type of sale 
to GPC has ended.

    The fourth source of non-Member revenues was primarily payments from GPC 
for use of the Integrated Transmission System ("ITS") and related 
transmission interfaces. GPC compensated Oglethorpe to the extent that 
Oglethorpe's percentage of investment in the ITS exceeded its percentage use 
of the system. In such case, Oglethorpe was entitled to compensation for the 
use of its investment by the other ITS participants. As a result of the 
Corporate Restructuring, all of the revenues in this category have accrued to 
GTC since April 1, 1997. The change in revenues for 1996 compared to 1995 
resulted from normal variations of Oglethorpe's investment percentages and 
its use of the system.

    The fifth source of non-Member revenue was plant operating agreements 
with GPC. The elimination of the revenues from the plant operating agreements 
was due to the scheduled conclusion, effective June 1, 1995, of the GPC 
Sell-back with respect to Plant Vogtle.

    OPERATING EXPENSES

    Oglethorpe's operating expenses decreased 3.7% in 1997 compared to 1996 
and decreased 2.6% in 1996 compared to 1995. The overall decrease in 
operating expenses for 1997 compared to 1996 was primarily attributable to 
the expenses relating to the transmission business assumed by GTC in 
connection with the Corporate Restructuring. The decrease in operating 
expenses in 1996 compared to 1995 was primarily attributable to energy cost 
savings achieved under the short-term power marketer arrangements offset 
somewhat by an increase in depreciation and amortization.

    The increase in 1997 production operations and maintenance costs was 
partly attributable to a maintenance outage at Scherer Unit No. 1. In 
addition, effective January 1, 1996, the costs of nuclear refueling outages 
are deferred and amortized over the 18-month period following the outage. 
Such change in accounting resulted in a $12.4 million deferral of maintenance 
costs in 1996.

    The decrease in total fuel costs in 1996 as compared to 1995 resulted 
partly from unplanned outages at Plant Scherer and Plant Wansley Unit No. 1 
and partly from the power marketer electing to dispatch the fossil units 
less. These factors resulted in 3.1% lower fossil generation in 1996 compared 
to 1995.

    Purchased power cost increased 16.5% in 1997 compared to 1996, despite 
the fact that effective September 1, 1997 another 250 megawatt ("MW") 
component block (coal-fired units) of the Block Power Sale Agreement (the 
"BPSA") between Oglethorpe and GPC was eliminated. Although 3.5% fewer 
megawatt-hours ("MWhs") were purchased in 1997 compared to 1996, average 
purchased power cost increased by 20.7%. As noted below, significant energy 
cost savings were realized in 1996 from the EPMI and DLD power marketer 
arrangements. Purchased power cost decreased by 14% in 1996 compared to 1995. 
Lower purchased power costs were achieved in 1996 despite a 15% increase in 
energy purchases in 1996 from 1995 levels. The 1996 cost reduction was due to 
(1) energy cost savings of $32 million realized from the short-term power 
marketer arrangements and (2) reductions in purchased power capacity costs 
due to (a) proceeds of $10.8 million from the settlement of a lawsuit with 
GPC and (b) savings resulting from the elimination effective September 1, 
1996, of a 250 MW component block (coal-fired units) of the BPSA between 
Oglethorpe and GPC.

    Purchased power expenses for the years 1995 through 1997 reflect the cost 
of capacity and energy purchases under various long-term power purchase 
agreements. These long-term agreements have, in some cases, take-or-pay 
minimum energy require-

                                             34



ments. For 1995 through 1997, Oglethorpe utilized its energy from these 
purchase power agreements in excess of the take-or-pay requirements. 
Oglethorpe's power purchases from these agreements amounted to approximately 
$176 million in 1997, $191 million in 1996 and $207 million in 1995. (For a 
discussion of the power purchase agreements, see Note 9 of Notes to Financial 
Statements.)

    The increase in depreciation and amortization in 1996 was partly due to a 
full year of depreciation on Rocky Mountain which began commercial operation 
in June 1995 and to $14 million of Board-approved accelerated amortization of 
deferred charges of the discontinued Pickens County pumped storage 
hydroelectric project. All remaining unamortized charges related to this 
project were expensed in 1996.

    Other operating expenses for 1996 and 1995 represent marketing services 
expenses. As discussed under "Other Income (Expense)" herein, such expenses 
for 1997 of approximately $18.3 million related to EnerVision were shown in 
"OTHER INCOME (EXPENSE)" since these marketing support activities are no 
longer part of operations of the power supply business.

    OTHER INCOME (EXPENSE)

    Interest income increased for 1997 compared to 1996 and 1996 compared to 
1995. Interest income was higher in 1997 as a result of higher earnings from 
the decommissioning fund and partly due to income from the deposits from the 
Rocky Mountain transactions. The deposits were made in December 1996 and 
January 1997. In 1996, interest income was higher due to higher average 
investment balances.

    In contemplation of separating its marketing support services from the 
power supply business, in 1997 Oglethorpe began accounting for the revenues 
and expenses relating to EnerVision as a non-operating "Other income 
(expense)" item. Such activities produced a margin of approximately $1.2 
million and are reflected in the "Other" caption of "Other income (expense)" 
on the Statement of Revenues and Expenses.

    In 1996, Oglethorpe utilized all remaining amounts available ($32 
million) under its deferred margin rate mechanism, and, as scheduled, this 
mechanism ended. Likewise, deferred margins of $16 million were amortized as 
credits against Member revenue requirements in 1995 to mitigate the rate 
impact of increased capacity costs related to Plant Vogtle and Rocky 
Mountain. Also, in 1995, Oglethorpe's Board of Directors authorized the 
retention of approximately $14 million in excess of the 1.07 TIER margin 
requirement as deferred margins under the mechanism. (See Note 1 of Notes to 
Financial Statements for a discussion of deferred margins and amortization of 
deferred margins.)

    INTEREST CHARGES

    Net interest charges for 1997 decreased compared to 1996 primarily due to 
the debt assumed by GTC in connection with the Corporate Restructuring. Net 
interest charges increased in 1996 compared to 1995 due to the decrease in 
allowance for debt funds used during construction ("AFUDC") as a result of 
the three units of Rocky Mountain becoming commercially operable in June and 
July 1995. The decrease in gross interest on long-term debt and capital 
leases in 1996 compared to 1995 was due to the refinancing efforts discussed 
under "Financial Condition--Refinancing Transactions" below.

FINANCIAL CONDITION

    GENERAL

    The principal changes in Oglethorpe's financial condition in 1997 were 
due to property additions, reductions in the cost of capital and a special 
patronage capital distribution. Property additions totaled $64 million and 
were funded entirely with funds from operations.

    A decrease in the cost of capital was achieved through the refinancing of 
$237 million of long-term debt and the prepayment of an additional $116 
million of long-term debt. The average interest rate on long-term debt 
decreased from 6.56% at December 31, 1996 to 6.46% at December 31, 1997. (For 
a further discussion of the refinancing transactions, see "REFINANCING 
TRANSACTIONS" and "ROCKY MOUNTAIN LEASE TRANSACTIONS" herein.)

    Finally, Oglethorpe's equity was reduced by $49 million due to a special 
patronage capital distribution made to the Members in conjunction with the 
Corporate Restructuring.

    CAPITAL REQUIREMENTS

    As part of its ongoing capital planning, Oglethorpe forecasts 
expenditures required for generation facilities and other capital projects. 
The table below details these expenditure forecasts for 1998 through 2000. 
Actual capital expenditures may vary from the 

                                             35



estimates listed below because of factors such as changes in business 
conditions, fluctuating rates of load growth, environmental requirements, 
design changes and rework required by regulatory bodies, delays in obtaining 
necessary federal and other regulatory approvals, construction delays, cost 
of capital, equipment, material and labor, and decisions to construct, rather 
than purchase, additional capacity.

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

(1) Consists of capital expenditures required for replacements and additions 
    to facilities in service and compliance with environmental regulations. 
    Oglethorpe currently does not have any new generation facilities under 
    construction.

(2) Allowance for funds used during construction of generation and general 
    plant facilities.

    Oglethorpe's investment in electric plant, net of depreciation, was 
approximately $3.6 billion as of December 31, 1997. The reduction in net 
plant compared to December 31, 1996 was primarily due to the transfer of 
assets to GTC and GSOC in connection with the Corporate Restructuring. 
Expenditures for property additions during 1997 amounted to $64 million and 
were funded entirely from operations. These expenditures were primarily for 
additions and replacements to generation facilities, and prior to the 
Corporate Restructuring, also for transmission facilities.

    In addition to the funds needed for capital expenditures, approximately 
$268 million will be required over the next three years (1998-2000) for 
current sinking fund requirements and maturities of long-term debt. Of this 
amount, $201 million, or 75%, relates to the repayment of RUS and Federal 
Financing Bank ("FFB") debt. Excluded from these amounts is the amount of 
debt assumed by GTC and GSOC as part of the Corporate Restructuring.

    LIQUIDITY AND SOURCES OF CAPITAL

    In the past, Oglethorpe has obtained the majority of its long-term 
financing from RUS-guaranteed loans funded by FFB. Oglethorpe has also 
obtained a substantial portion of its long-term financing requirements from 
tax-exempt pollution control revenue bonds ("PCBs").

    In addition, Oglethorpe's operations have consistently provided a sizable 
contribution to its funding of capital requirements, such that internally 
generated funds have provided interim funding or long-term capital for 
nuclear fuel reloads, new generation, transmission and general plant 
facilities, replacements and additions to existing facilities, and retirement 
of long-term debt. Oglethorpe anticipates that it will meet its future 
capital requirements through 2000 primarily with funds generated from 
operations and, if necessary, with short-term borrowings.

    To meet short term cash needs and liquidity requirements, Oglethorpe had, 
as of December 31, 1997, (i) approximately $63 million in cash and temporary 
cash investments, (ii) $97 million in other short term investments and (iii) 
up to $330 million total available under the following credit facilities ($92 
million of which was in use):



SHORT-TERM CREDIT FACILITIES                                    AMOUNT
- ----------------------------------------------------------  --------------
                                                         
Commercial Paper..........................................  $  280,000,000
Committed lines of credit: SunTrust Bank..................      30,000,000
Uncommitted lines of credit: CFC..........................      50,000,000


    Under its commercial paper program, Oglethorpe may issue commercial paper 
not to exceed $280 million outstanding at any one time. The commercial paper 
is backed 100% by committed lines of credit provided by a group of banks for 
which SunTrust Bank acts as agent. The maximum amount that can be outstanding 
at any one time under the commercial paper program and the other lines of 
credit totals $330 million due to certain restrictions contained in the 
SunTrust Bank committed line of credit agreement. As of December 31, 1997, 
$92 million of commercial paper was outstanding which was issued to fund the 
defeasance of certain PCBs in conjunction with the Corporate Restructuring. 
(See "REFINANCING TRANSACTIONS" below for a further discussion of this 
defeasance.)

    REFINANCING TRANSACTIONS

    Over the past few years, Oglethorpe has implemented a program to reduce 
its interest costs by refinancing a sizable portion of its high-interest rate 
debt. Since the first transaction was completed in June 1992, Oglethorpe has 
refinanced $1.2 billion in FFB debt, $1.1 billion in PCB debt and $225 
million in serial facility bond debt. Refinancings completed in 1997 include 
the $225 million of serial facility bonds and the refinancing of $14.6 
million of maturing PCB principal.

                                             36



    Oglethorpe has also prepaid $222 million of FFB debt, including 1997 
prepayments of $92 million of FFB debt in connection with the Rocky Mountain 
transactions described herein and a prepayment of $25 million of FFB debt in 
connection with the Corporate Restructuring. (See Note 5 of Notes to 
Financial Statements.)

    The net result of these transactions has been to reduce the average 
interest rate on Oglethorpe's total long-term debt from 8.83% at December 31, 
1991 to 6.46% at December 31, 1997.

    Oglethorpe has implemented a program under which it is refinancing, on a 
continued tax-exempt basis, the annual principal maturities of certain 
tax-exempt serial bonds and tax-exempt term bonds under their mandatory 
sinking fund schedules. The refinancing of these principal maturities allows 
Oglethorpe to preserve a low-cost source of financing while conserving cash. 
To date, Oglethorpe has refinanced approximately $53 million under this 
program, including $14.6 million in 1997, and has a plan in place to 
refinance principal maturities relating to certain PCB issues through the 
year 2002.

    In connection with the Corporate Restructuring, Oglethorpe defeased 
approximately $92 million in principal amount of Series 1992 PCBs. Initially 
these bonds have been defeased with proceeds from the issuance of 
approximately $92 million in commercial paper. Oglethorpe has a plan in place 
to refinance the commercial paper issuance with a medium-term loan in 1998 
and ultimately expects to refinance the loan with an issuance of PCBs at some 
point in the future.

    Also, in connection with the Corporate Restructuring, Oglethorpe 
refinanced approximately $217 million in principal amount of Series 1992A 
PCBs through the issuance of PCBs maturing on December 1, 1997 (the "Series 
1997A Bonds"), which were in turn refinanced through the issuance of PCBs 
maturing on May 28, 1998 (the "Series 1997B Bonds"). Oglethorpe has a plan in 
place and is in the final stages of a debt offering to refund the Series 
1997B Bonds in March 1998 through the issuance of the Series 1998A and Series 
1998B PCBs (the "Series 1998 Bonds"), having a January 1, 2019 maturity. The 
Series 1998 Bonds will be issued as variable rate bonds and will be supported 
by both a municipal bond insurance policy and bank liquidity agreements.

    INTEREST RATE SWAP TRANSACTIONS

    To refinance high-interest rate PCBs, Oglethorpe entered into two 
interest rate swap transactions with a swap counterparty, AIG Financial 
Products Corp. ("AIG-FP"), which were designed to create a contractual fixed 
rate of interest on $322 million of variable rate PCBs. These transactions 
were entered into in early 1993 on a forward basis, pursuant to which 
approximately $200 million of variable rate PCBs were issued on November 30, 
1993 and approximately $122 million of variable rate PCBs were issued on 
December 1, 1994. Oglethorpe is obligated to pay the variable interest rate 
that accrues on these PCBs; however, the swap arrangements provide a 
mechanism for Oglethorpe to achieve a contractual fixed rate which is lower 
than Oglethorpe would have obtained had it issued fixed rate bonds. 
Oglethorpe's use of financial derivatives is for the purpose of mitigating 
business risks and is not for speculative purposes. Oglethorpe's use of 
derivatives is currently limited to these two swap transactions.

    In connection with GTC's assumption of liability on a portion of the PCBs 
pursuant to the Corporate Restructuring, commencing April 1, 1997, GTC 
assumed and agreed to pay 16.86% of any amounts due from Oglethorpe under 
these swap arrangements, including the net swap payments and termination 
payments described below. Should GTC fail to make such payments under the 
assumption, Oglethorpe remains obligated for the full amount of such payments.

    Under the swap arrangements, Oglethorpe is obligated to make periodic 
payments to AIG-FP based on a notional principal amount equal to the 
aggregate principal amount of the bonds outstanding during the period and a 
contractual fixed rate ("Fixed Rate"), and AIG-FP is obligated to make 
periodic payments to Oglethorpe based on a notional principal amount equal to 
the aggregate principal amount of the bonds outstanding during the period and 
a variable rate equal to the variable rate of interest accruing on the bonds 
during the period ("Variable Rate"). These payment obligations are netted, 
such that if the Variable Rate is less than the Fixed Rate, Oglethorpe makes 
a net payment to AIG-FP. Likewise, if the Variable Rate is higher than the 
Fixed Rate, Oglethorpe receives a net payment from AIG-FP. Thus, although 
changes in the Variable Rate affect whether Oglethorpe is obligated to make 
payments to AIG-FP or is entitled to receive payments from AIG-FP, the 
effective interest rate Oglethorpe pays with respect to the PCBs is not 
affected by changes in interest rates. The Fixed Rate for the $200 million of 
variable rate bonds issued in 1993 is 5.67% and the Fixed Rate for the $122 
million of variable rate bonds issued in 1994 is 6.01%. For the three years 
ended December 31, 1995, 1996 and 1997, Oglethorpe has made in connection 
with both interest rate swap arrangements combined net swap payments to 
AIG-FP of $6.4 million, $8.2 million and $6.4 million, respectively.

                                             37



    The swap arrangements extend for the life of these pcbs.  If the swap 
arrangements were to be terminated while the PCBs are still outstanding, 
Oglethorpe or AIG-FP may owe the other party a termination payment depending 
on a number of factors, including whether the fixed rate then being offered 
under comparable swap arrangements is higher or lower than the Fixed Rate. 
Under the terms of the swap agreements, AIG-FP has limited rights to 
terminate the swaps only upon the occurrence of specified events of default 
or a reduction in ratings on Oglethorpe's PCBs, without credit enhancement, 
to a level that is below investment grade. Oglethorpe estimates that its 
maximum aggregate liability (net of GTC's assumed percentage) for termination 
payments under both swap arrangements had such payments been due on December 
31, 1997 would have been approximately $38 million.

    In connection with these interest rate swap arrangements, Oglethorpe (but 
not GTC) is obligated to maintain minimum liquidity in an amount equal to 25% 
of the principal amount of the variable rate PCBs outstanding. As of December 
31, 1997, the minimum liquidity requirement equaled $81 million and will 
decrease proportionately as such bonds are retired as a result of scheduled 
sinking fund payments.

    ROCKY MOUNTAIN LEASE TRANSACTIONS

    Oglethorpe completed, in two separate closings on December 31, 1996 and 
January 3, 1997, lease transactions for its 74.61% undivided ownership 
interest in Rocky Mountain. Under the terms of these transactions, Oglethorpe 
leased the facility to three institutional investors for the useful life of 
the facility, who in turn leased it back to Oglethorpe for a term of 30 
years. Rocky Mountain is subject to the lien of the Mortgage Indenture. The 
leasehold interest transferred is subject and subordinate to such lien. 
Oglethorpe will continue to control and operate the plant during the 
leaseback term, and will exercise its fixed price purchase option at the end 
of the leaseback period so as to retain all other rights of ownership with 
respect to the plant if it is advantageous for Oglethorpe to exercise such 
option. As a result of these transactions, Oglethorpe received net present 
value cash benefits of approximately $96 million that is being recorded as a 
deferred credit and will be recognized in income over the term of the 
leaseback. Approximately $92 million was used for the early retirement of FFB 
debt and approximately $4 million was used to pay alternative minimum taxes 
on the transactions. The combination of the debt prepayment and the amortized 
gain will result in an estimated $11 million in annual savings through 2001, 
and additional savings in declining amounts for the remaining 25 years of the 
lease. In connection with these transactions, Oglethorpe is obligated to 
maintain minimum liquidity of $50 million.

    SCHERER UNIT NO. 1 LEASE TRANSACTION

    Oglethorpe is considering a lease transaction for its 60% interest in 
Scherer Unit No. 1. Should Oglethorpe decide to proceed with this 
transaction, it could close in mid-to-late 1998. This transaction, if 
completed, would provide a substantial up-front cash payment to Oglethorpe 
which would be amortized over the term of the lease to reduce revenue 
requirements from the Members. Oglethorpe expects that substantially all of 
any such net cash benefit would be used to prepay a portion of FFB debt.

    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 
transmission access and pricing, state deregulation initiatives, increased 
consolidation and mergers of electric utilities, the proliferation of power 
marketers and independent power producers, surplus generation 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. No legislation related to retail wheeling has yet 
been enacted in Georgia, and, currently, no bill is 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 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. The GPSC has issued a report 
identifying electric industry restructuring issues, potential resolutions and 
the views of the parties who participated in the workshops. 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 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 future legislative activities in Georgia.

    Under current Georgia law, the Members general-

                                             38


ly have the exclusive right to provide retail electric service in their 
respective territories. Since 1973, however, Georgia has permitted limited 
competition among electric utilities located in Georgia for sales of 
electricity to certain large commercial or industrial customers. Pursuant to 
the Territorial Act, 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.

    Over the past years, 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 and to reduce the possibility of 
incurring stranded costs. Most importantly, Oglethorpe completed the 
Corporate Restructuring and divided itself into generation, transmission and 
system operations companies in order to better serve its Members in a 
deregulated and competitive environment. (See "General"Corporate 
Restructuring" herein.) Since 1992, Oglethorpe also has pursued an interest 
cost reduction program. As a result of this program, Oglethorpe has prepaid 
$222 million of FFB debt and refinanced $1.2 billion of FFB debt, $1.1 
billion of PCB debt and $225 million of serial facility bond debt. These 
steps have reduced Oglethorpe's interest costs significantly. (See "Financial 
Condition"Refinancing Transactions" herein.)

    Oglethorpe and the Members also amended the Wholesale Power Contracts in 
connection with the Corporate Restructuring. The Wholesale Power Contracts 
provide that the Members are jointly and severally responsible for all costs 
and expenses of all existing generation and purchased power resources of 
Oglethorpe, as well as certain future power resources. Each Wholesale Power 
Contract specifically provides that the Member must make payments whether or 
not power has been delivered and whether or not a plant has been sold or is 
otherwise unavailable. The formulary rate established by Oglethorpe in the 
rate schedule to the Wholesale Power Contracts employs a rate methodology 
under which all categories of costs are specifically separated as components 
of a formula to determine Oglethorpe's revenue requirements. The rate 
schedule also allocates to the Members the responsibility for all of 
Oglethorpe's fixed costs. The Board of Directors may adjust Oglethorpe's 
charges under the Wholesale Power Contracts. With respect to Oglethorpe, the 
RUS has retained certain approval rights over the changes to the Wholesale 
Power Contracts, including the rate schedule. (See "General-RATES AND 
FINANCIAL COVERAGE REQUIREMENTS" herein.) As a result of these contractual 
agreements, the Members ultimately are liable for the existing power 
resources of Oglethorpe.

    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 suppliers. (See "Results of Operations-POWER MARKETER 
ARRANGEMENTS" herein.)

    Oglethorpe and the Members continue to consider and evaluate a wide array 
of other potential actions to reduce costs and to maintain their 
competitiveness in anticipation of future competition. These activities on 
the part of Oglethorpe and the Members are in various stages of study or 
preliminary consideration. 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. Oglethorpe continues to seek to identify and evaluate 
opportunities to reduce the cost of wholesale power to the Members.

    Oglethorpe currently defers certain costs of providing services to the 
Members pursuant to Statement of Financial Accounting Standards ("SFAS") No. 
71, "Accounting for the Effects of Certain Types of Regulation." Note 1 of 
Notes to Financial Statements sets forth the regulatory assets and 
liabilities reflected on Oglethorpe's balance sheet as of December 31, 1997. 
Regulatory assets represent probable future revenues to Oglethorpe associated 
with certain costs that will be recovered from Members through the ratemaking 
process. Regulatory liabilities represent probable future reduction in 
revenues associated with amounts that are to be credited to Members through 
the ratemaking process. (See "General-RATES AND FINANCIAL COVERAGE 
REQUIREMENTS" herein.) In the event that Oglethorpe is no longer subject to 
the provisions of SFAS No. 71, Oglethorpe would be required to write off 
regulatory assets and liabilities. In addition, Oglethorpe would be required 
to determine any 

                                             39



impairment to other assets, including plant, and write down the assets, if 
impaired, to their fair value.

    At this time, Oglethorpe cannot predict 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.

MISCELLANEOUS

    DECOMMISSIONING COSTS

    The staff of the Securities and Exchange Commission (the "Commission") 
has questioned certain of the current accounting practices of the electric 
utility industry regarding the recognition, measurement and classification of 
decommissioning costs for nuclear generating facilities in financial 
statements of electric utilities. In response to these questions, the 
Financial Accounting Standards Board has issued an Exposure Draft of a 
proposed Statement on "Accounting for Certain Liabilities Related to Closure 
or Removal of Long-Lived Assets". The proposed Statement would require the 
recognition of the entire obligation for decommissioning at its present value 
as a liability in the financial statements. Rate-regulated utilities would 
also recognize an offsetting asset for differences in the timing of 
recognition of the costs of decommissioning for financial reporting and 
ratemaking purposes. Oglethorpe's management does not believe that this 
proposed Statement would have an adverse effect on results of operations due 
to its current and future ability to recover decommissioning costs through 
rates.

    Beginning in years 2014 through 2029, it is expected that Plant Hatch and 
Plant Vogtle units will begin the decommissioning process. The expected 
timing of payments for decommissioning costs will extend for a period of 9 to 
14 years. Oglethorpe's management does not expect such payments to have an 
adverse impact on liquidity or capital resources due to available amounts 
that have been placed in reserves for this purpose.

    INFLATION

    As with utilities generally, inflation has the effect of increasing the 
cost of Oglethorpe's operations and construction program. Operating and 
construction costs have been less affected by inflation over the last few 
years because rates of inflation have been relatively low.

    YEAR 2000 ISSUE

    Many information systems have been designed to function based on years 
that begin with "19". Oglethorpe expects that by the year 2000 it will have 
adapted its systems, to the extent it considers necessary, to process years 
that begin with "20", and does not expect that the year 2000 issue will have 
a material adverse effect on its financial condition or results of operations.

    FORWARD-LOOKING STATEMENTS AND ASSOCIATED RISKS

    This Annual Report on Form 10-K contains forward-looking statements, 
including statements regarding, among other items, (i) anticipated trends in 
Oglethorpe's business and (ii) Oglethorpe's future liquidity requirements and 
capital resources. These forward-looking statements are based largely on 
Oglethorpe's expectations and are subject to a number of risks and 
uncertainties, certain of which are beyond Oglethorpe's control. For factors 
that could cause actual results to differ materially from those anticipated 
by these forward-looking statements, see "Competition" herein and "CERTAIN 
FACTORS AFFECTING THE ELECTRIC UTILITY INDUSTRY" in Item 1. In light of these 
risks and uncertainties, there can be no assurance that events anticipated by 
the forward-looking statements contained in this Annual Report will in fact 
transpire.

                         NOTES TO FINANCIAL STATEMENTS
              FOR THE YEARS ENDED DECEMBER 31, 1997, 1996 AND 1995
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
A. BUSINESS DESCRIPTION
 
    Oglethorpe Power Corporation (Oglethorpe) is an electric membership
corporation incorporated in 1974 and headquartered in suburban Atlanta.
Oglethorpe provides wholesale electric service, on a not-for-profit basis, to 39
of Georgia's 42 Electric Membership Corporations (EMCs). These 39 electric
distribution cooperatives (Members) in turn distribute energy on a retail basis
to approximately 2.8 million people across two-thirds of the State. Oglethorpe
is the nation's largest electric cooperative in terms of operating revenues,
assets, kilowatt-hour sales and, through its Members, consumers served.
 
    Oglethorpe owns or leases undivided interests in thirteen generating units
totaling 3,335 megawatts (MW) of capacity. Oglethorpe also purchases a total of
1,250 MW of power pursuant to power purchase agreements. In addition Oglethorpe
has contracted to purchase 435 MW of peaking capacity during the summer of 1998.
 
    Oglethorpe and the Members completed on March 11, 1997, a corporate
restructuring (the Corporate Restructuring) in which Oglethorpe, effective April
1, 1997, was divided into three specialized operating companies to respond to
increasing competition and regulatory changes in the electric industry.
Oglethorpe's transmission business was sold to, and is now owned and operated by
Georgia Transmission Corporation (GTC), a Georgia electric membership
corporation formed for that purpose. Oglethorpe's system operations business was
sold to and is now owned and operated by, Georgia System Operations Corporation
(GSOC), a Georgia nonprofit corporation formed for that purpose. Oglethorpe
continues to own and operate its power supply business. For more information
regarding the Corporate Restructuring, see Note 11.
 
B. BASIS OF ACCOUNTING
 
    Oglethorpe follows generally accepted accounting principles and the
practices prescribed in the Uniform System of Accounts of the Federal Energy
Regulatory Commission (FERC) as modified and adopted by the Rural Utilities
Service (RUS).
 
    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities as of December 31, 1997 and 1996
and the reported amounts of revenues and expenses for each of the three years
ending December 31, 1997. Actual results could differ from those estimates.
 
C. PATRONAGE CAPITAL AND MEMBERSHIP FEES
 
    Oglethorpe is organized and operates as a cooperative. The Members paid a
total of $195 in membership fees. Patronage capital is the retained net margin
of Oglethorpe. As provided in the bylaws, any excess of revenue over
expenditures from operations is treated as advances of capital by the Members
and is allocated to each of them on the basis of their electricity purchases
from Oglethorpe.
 
    Any distributions of patronage capital are subject to the discretion of 
the Board of Directors, subject to Indenture requirements. Under the Mortgage 
Indenture, Oglethorpe is prohibited from making any distribution of patronage 
capital to the Members if, at the time thereof or giving effect thereto, (i) 
an event of default exists under the Mortgage Indenture, (ii) Oglethorpe's 
equity as of the end of the immediately preceding fiscal quarter is less than 
20% of Oglethorpe's total capitalization, or (iii) the aggregate amount 
expended for distributions on or after the date on which Oglethorpe's equity 
first reaches 20% of Oglethorpe's total capitalization exceeds 35% of 
Oglethorpe's aggregate net margins earned after such date. This last 
restriction, however will not apply if, after giving effect to such 
distribution, Oglethorpe's equity as of the end of the immediately preceding 
fiscal quarter is not less than 30% of Oglethorpe's total capitalization.
 
D. MARGIN POLICY
 
    Under Oglethorpe's prior RUS mortgage, Oglethorpe's margin policy was based
on the provision of a Times Interest Earned Ratio (TIER) established annually by
the Oglethorpe Board of Directors. Pursuant to this policy, the annual net
margin goal for 1996 and 1995 was the amount required to produce a TIER of 1.07.
The RUS Mortgage was replaced with the Mortgage Indenture in connection with
Oglethorpe's corporate restructuring. For 1997 under the Mortgage Indenture,
Oglethorpe is required to produce a Margins for Interest (MFI) Ratio of at least
1.10.
 
    The Oglethorpe Board of Directors adopted resolutions annually requiring
that Oglethorpe's net margins for the years 1985 through 1995 in excess of its

                                             47


annual margin goals be deferred and used to mitigate rate increases associated
with Plant Vogtle and Rocky Mountain. In addition, during 1986 and 1987,
Oglethorpe's wholesale electric rate to its Members provided for a one mill per
kilowatt-hour charge (Vogtle Surcharge), also to be used to mitigate the effect
of Plant Vogtle on rates.
 
    Pursuant to rate actions by Oglethorpe's Board of Directors, specified
amounts of deferred margins and Vogtle Surcharge were returned in 1989 through
1995 and all remaining amounts were returned in 1996.
 
E. OPERATING REVENUES
 
    Operating revenues consist primarily of electricity sales pursuant to
long-term wholesale power contracts which Oglethorpe maintains with each of its
Members. These wholesale power contracts obligate each Member to pay Oglethorpe
for capacity and energy furnished in accordance with rates established by
Oglethorpe. Energy furnished is determined based on meter readings which are
conducted at the end of each month. Actual energy costs are compared, on a
monthly basis, to the billed energy costs, and an adjustment to revenues is made
such that energy revenues are equal to actual energy costs.
 
    Revenues from Cobb EMC and Jackson EMC, two of Oglethorpe's Members,
accounted for 12.9% and 11.8% in 1997, 12.5% and 11.2% in 1996, and 11.3% and
10.4% in 1995, respectively, of Oglethorpe's total operating revenues.
 
F. NUCLEAR FUEL COST
 
    The cost of nuclear fuel, including a provision for the disposal of spent
fuel, is being amortized to fuel expense based on usage. The total nuclear fuel
expense for 1997, 1996 and 1995 amounted to $47,123,000, $49,298,000 and
$54,588,000, respectively.
 
    Contracts with the U.S. Department of Energy (DOE) have been executed to
provide for the permanent disposal of spent nuclear fuel for the life of Plant
Hatch and Plant Vogtle. The services to be provided by DOE were scheduled to
begin in 1998; however, the DOE has stated that permanent nuclear waste storage
facilities are not available, and it is uncertain when they will be available.
The Plant Hatch spent fuel storage is expected to be sufficient into 2003. The
Plant Vogtle spent fuel storage is expected to be sufficient into 2008.
Activities for adding dry cask storage capacity at Plant Hatch by 2000 are in
progress.

    The Energy Policy Act of 1992 required that utilities with nuclear plants be
assessed over a 15-year period an amount which will be used by DOE for the
decontamination and decommissioning of its nuclear fuel enrichment facilities.
The amount of each utility's assessment was based on its past purchases of
nuclear fuel enrichment services from DOE. Based on its ownership in Plants
Hatch and Vogtle, Oglethorpe has a remaining nuclear fuel asset of approximately
$13,500,000, which is being amortized to nuclear fuel expense over the next 10
years. Oglethorpe has also recorded an obligation to DOE which approximated
$10,600,000 at December 31, 1997.
 
G. NUCLEAR DECOMMISSIONING
 
    Oglethorpe's portion of the costs of decommissioning co-owned nuclear
facilities is estimated as follows:
 


                                                                      HATCH       HATCH       VOGTLE       VOGTLE

- -----------------------------------------------------------------  -----------  ----------  -----------  ----------
                                                                                             
Year of site study...............................................        1994         1994        1994         1994

Expected start date of decommissioning...........................        2014         2018        2027         2029

Decommissioning cost:

Discounted.......................................................   $  92,000   $  109,000   $  82,000   $  106,000

Undiscounted.....................................................     157,000      207,000     198,000      271,000

 
    The decommissioning cost estimates are based on prompt dismantlement and
removal of the plant from service. The actual decommissioning costs may vary
from the above estimates because of changes in the assumed date of
decommissioning, changes in regulatory requirements, changes in technology, and
changes in costs of labor, materials and equipment.
 
    The annual provision for decommissioning for 1997, 1996 and 1995 was
$2,597,000, $2,597,000 and $4,156,000, respectively. In developing the amount of
the annual provision for 1997 and 1998, the escalation rate was assumed to be
2.72% and return on trust assets was assumed to be 8%. Oglethorpe accounts for
this provision for decommissioning as depreciation expense with an offsetting
credit to a decommissioning reserve. Oglethorpe's management is of the opinion
that any changes in cost estimates of decommissioning can be recovered in future
rates.
 
    In compliance with a Nuclear Regulatory Commission (NRC) regulation,
Oglethorpe maintains an external trust fund to provide for a portion of the cost
of decommissioning its nuclear facilities. The NRC regulation requires funding
levels based on average expected cost to decommission only the radioactive
portions of a typical nuclear facility. Oglethorpe's decommissioning reserve
reflects its obligation to decommission both the radioactive and most of the
non-radioactive portions of its nuclear facilities.
 
    Realized investment earnings from the external trust fund, while increasing
the fund and interest income, also are applied to the decommissioning 

                                             48


reserve and charged to interest expense. Interest income earned from the 
external trust fund is offset by the recognition of interest expense such 
that there is no effect on Oglethorpe's net margin.

H. DEPRECIATION
 
    Depreciation is computed on additions when they are placed in service using
the composite straight-line method. Annual depreciation rates in effect in 1997,
1996 and 1995 were as follows:
 


                                                                              1997         1996         1995
                                                                           -----------  -----------  -----------

I. ELECTRIC PLANT
 
    Electric plant is stated at original cost, which is the cost of the plant
when first dedicated to public service, plus the cost of any subsequent
additions. Cost includes an allowance for the cost of equity and debt funds used
during construction. The cost of equity and debt funds is calculated at the
embedded cost of all such funds. The plant acquisition adjustments represent the
excess of the cost of the plant to Oglethorpe over the original cost, less
accumulated depreciation at the time of acquisition, and are being amortized
over a ten-year period.
 
    Maintenance and repairs of property and replacements and renewals of items
determined to be less than units of property are charged to expense.
Replacements and renewals of items considered to be units of property are
charged to the plant accounts. At the time properties are disposed of, the
original cost, plus cost of removal, less salvage of such property, is charged
to the accumulated provision for depreciation.
 
J. BOND, RESERVE AND CONSTRUCTION FUNDS:
 
    Bond, reserve and construction funds for pollution control revenue bonds
(PCBs) are maintained as required by Oglethorpe's bond agreements. Bond funds
serve as payment clearing accounts, reserve funds maintain amounts equal to the
maximum annual debt service of each bond issue and construction funds hold bond
proceeds for which construction expenditures have not yet been made. As of
December 31, 1997 and 1996, substantially all of the funds were invested in U.S.
Government securities.
 
K. CASH AND TEMPORARY CASH INVESTMENTS
 
    Oglethorpe considers all temporary cash investments purchased with a
maturity of three months or less to be cash equivalents. Temporary cash
investments with maturities of more than three months are classified as other
short-term investments.
 
    At December 31, 1997, $12,167,000 was restricted by PCBs trust indentures
and was utilized in January 1998 for payment of principal on certain PCBs. Of
the amount reported as cash and temporary cash investments at December 31, 1996,
approximately $65,600,000 was restricted by RUS and was utilized by Oglethorpe
for the purpose of prepaying certain Federal Financing Bank (FFB) long-term debt
in March 1997.
 
L. INVENTORIES
 
    Oglethorpe maintains inventories of fossil fuels for its generation plant
and spare parts for certain of its generation and transmission plant. These
inventories are stated at weighted average cost on the accompanying balance
sheets.

    At December 31, 1997 and 1996, fossil fuels inventories were $7,288,000 and
$23,062,000, respectively. Inventories for spare parts at December 31, 1997 and
1996 were $58,240,000 and $66,763,000, respectively.
 
M. DEFERRED CHARGES
 
    Prior to 1996, Oglethorpe expensed nuclear refueling outage costs as 
incurred. In 1996, Oglethorpe began accounting for these costs on a 
normalized basis. Under this method of accounting, refueling outage costs are 
deferred and subsequently amortized to expense over the 18-month operating 
cycle of each unit. Deferred nuclear outage costs at December 31, 1997 and 
1996 were $19,802,000 and $12,961,000, respectively.
 
    As a result of the availability of long-term capacity purchases at similar
costs but with reduced risks to Oglethorpe and its Members, Oglethorpe
determined that the Smarr Combustion Turbine Project was not needed within the
present planning horizon. Therefore, Oglethorpe is amortizing the accumulated
project costs in excess of the current value of the land purchased. The
remaining project costs of $5,947,000 are reflected as deferred charges on the
accompanying balance sheets. In 1995, Oglethorpe's Board of Directors authorized
that these project costs be amortized and fully recovered through future rates
over a period of 15 years beginning in that year.
 
                                             49


N. DEFERRED CREDITS
 
    In April 1982, Oglethorpe sold to three purchasers certain of the income tax
benefits associated with Scherer Unit No.1 and related common facilities
pursuant to the safe harbor lease provisions of the Economic Recovery Tax Act of
1981. Oglethorpe received a total of approximately $110,000,000 from the safe
harbor lease transactions. Oglethorpe accounts for the net benefits as a
deferred credit and is amortizing the amount over the 20-year term of the
leases.
 
    In December 1996 and January 1997, Oglethorpe entered into long-term lease
transactions for its 74.6% undivided ownership interest in the Rocky Mountain
Pumped Storage Hydroelectric Project (Rocky Mountain). The lease transactions
are characterized as a sale and lease-back for income tax purposes, but not for
financial reporting purposes. As a result of these leases, Oglethorpe recorded a
net benefit of $95,560,000 which was deferred and is being amortized to income
over the 30-year lease-back period. The lease transactions initially increased
Oglethorpe's Capitalization and Investments and funds by $57,495,000,
respectively (see Note 2 where discussed further).
 
O. REGULATORY ASSETS AND LIABILITIES
 
    Oglethorpe is subject to the provisions of Statement of Financial Accounting
Standards No. 71, "Accounting for the Effects of Certain Types of Regulation."
Regulatory assets represent probable future revenues to Oglethorpe associated
with certain costs which will be recovered from Members through the rate-making
process. Regulatory liabilities represent probable future reduction in revenues
associated with amounts that are to be credited to Members through the
rate-making process. The following regulatory assets and liabilities were
reflected on the accompanying balance sheets as of December 31, 1997 and 1996:

    In the event that Oglethorpe is no longer subject to the provisions of
Statement No. 71, Oglethorpe would be required to write off related regulatory
assets and liabilities. In addition, Oglethorpe would be required to determine
any impairment to other assets, including plant, and write down the assets, if
impaired, to their fair value.

    Oglethorpe uses the methods and assumptions described below to estimate the
fair value of each class of financial instruments. For cash and temporary cash
investments, the carrying amount approximates fair value because of the
short-term maturity of those instruments. The fair value of Oglethorpe's
long-term debt and the swap arrangements is estimated based on the quoted market
prices for the same or similar issues or on the current rates offered to
Oglethorpe for debt of similar maturities.
 
    A portion (16.86%) of the interest rate swap arrangements was assumed by 
GTC as part of the Corporate Restructuring. Under the interest rate swap
arrangements, Oglethorpe makes payments to the counterparty based on the
notional principal at a contractually fixed rate and the counterparty makes
payments to Oglethorpe based on the notional principal at the existing variable
rate of the refunding bonds. The differential to be paid or received is accrued
as interest rates change and is recognized as an adjustment to interest expense.
Oglethorpe entered into the swap arrangements for the purpose of securing a
fixed rate lower than otherwise would have been available to Oglethorpe had it
issued fixed rate bonds. For the Series 1993A notes, the notional principal was
$199,690,000 (includes the portion assumed by GTC) and the fixed swap rate is
5.67% (the variable rate at December 31, 1997 and 1996 was 3.65% and 4. %
respectively). With respect to the Series 1994A notes, the notional principal
was $122,740,000 (includes the portion assumed by GTC) and the fixed swap rate
is 6.01% (the variable rate at December 31, 1997 and 1996 was 3.65% and 4.00%,
respectively). The notional principal amount is used to measure the amount of
the swap payments and does not represent additional principal due to the
counterparty. The swap arrangements extend for the life of the refunding bonds,
with reductions in the outstanding principal amounts of the refunding bonds
causing corresponding reductions in the notional amounts of the swap payments.
Oglethorpe's portion of the estimated fair value of the swap arrangements at
December 31, 1997 and 1996 was an unrealized loss of $38,349,000 and
$33,938,000, respectively, representing the payment Oglethorpe would pay if the
swap arrangements were terminated. Oglethorpe may be exposed to losses in the
event of nonperformance of the counterparty, but does not anticipate such
nonperformance.

    Under Statement of Financial Accounting Standards No. 115, "Accounting for
Certain Investments in Debt and Equity Securities," investment securities held
by Oglethorpe are classified as either available-for-sale or held-to-maturity.
Available-for-sale securities are carried at market value with unrealized gains
and losses, net of any tax effect, added to or deducted from patronage capital.
Unrealized gains and losses from investment securities held in the
decommissioning fund, which are also classified as available-for-sale, are
directly added to or deducted from the decommissioning reserve. Held-to-maturity
securities are carried at cost. All realized and unrealized gains and losses are
determined using the specific identification method. Gross unrealized gains and
losses at December 31, 1997 were $12,800,000 and $5,583,000, respectively. Gross
unrealized gains and losses at December 31, 1996 were $7,785,000 and $4,985,000
respectively. For 1997 and 1996, proceeds from sales of available-for-sale
securities totaled $476,965,000 and $425,772,000, respectively. Gross realized
gains and losses from the 1997 sales were $11,415,000 and $3,010,000,
respectively. Gross realized gains and losses from the 1996 sales were
$6,410,000 and $3,671,000, respectively.

    Investments in associated organizations were as follows at December 31, 1997

    The investments in these associated organizations are similar to
compensating bank balances in that they are required in order to maintain
current financing arrangements. Accordingly, there is no market for these
investments.
 
    The deposit on the Rocky Mountain transactions (see Note 1 where discussed)
is invested in a guaranteed investment contract which will be held to maturity
(the end of the 30-year lease-back period). At maturity, Oglethorpe fully
intends to use the deposit to repurchase tax ownership and to retain all other
rights of ownership with respect to the plant. The deposit is carried at cost.
 
    In addition, from the proceeds of the Rocky Mountain transactions,
Oglethorpe paid $640,611,000 to a financial institution. In return, this
financial institution undertook to pay a portion of Oglethorpe's lease
obligations. Both Oglethorpe's interest in this payment undertaking agreement
and the corresponding lease obligations have been extinguished for financial
reporting purposes.
 
3. INCOME TAXES
 
    Oglethorpe is a not-for-profit membership corporation subject to Federal and
state income taxes. As a taxable electric cooperative, Oglethorpe has annually
allocated its income and deductions between Member and non-Member activities.
Any Member taxable income has been offset with a patronage exclusion and member
loss carryforwards.
 
    Oglethorpe accounts for its income taxes pursuant to Statement of Financial
Accounting Standards (SFAS) No. 109. SFAS No. 109 requires the recognition of
deferred tax assets and liabilities for the expected future tax consequences of
events that have been included in the financial statements or tax returns.
 
    A detail of the provision for income taxes in 1997, 1996 and 1995 is shown
as follows:

    Based on Oglethorpe's historical taxable transactions, the timing of the
reversal of existing temporary differences, future income, and tax planning
strategies, it is more likely than not that Oglethorpe's future taxable income
will be sufficient to realize the benefit of NOLs before their respective
expiration dates. The NOLs expiration dates start in the year 2 3 and end in the
year 2010. However, as reflected in the above valuation allowance, it is more
likely than not that the tax credits will not be utilized before expiration. It
is more likely than not that the AMT credit will be utilized.
 
    4. CAPITAL LEASES:
 
    In December 1985, Oglethorpe sold and subsequently leased back from four
purchasers its 60% undivided ownership interest in Scherer Unit No. 2. The gain
from the sale is being amortized over the 36-year term of the leases. The 
minimum lease payments under the capital leases together with the present 
value of net minimum lease payments as of December 31, 1997 are as follows:

    The capital leases provide that Oglethorpe's rental payments vary to the
extent of interest rate changes associated with the debt used by the lessors to
finance their purchase of undivided ownership shares in Scherer Unit No. 2. In
December 1997, Oglethorpe refinanced the debt supporting the Scherer Unit No. 2
lease. The refunded debt consisted of $143,200,000 in serial facility bonds with
a 9.70% fixed interest rate (pertaining to three of the lessors) and $81,500,000
in bank debt with variable interest rates ranging from 6.4% to 6.9% (pertaining
to the remaining lessor). The debt was refinanced through a $224,700,000 issue
of serial facility bonds due June 30, 2011 with a 6.97% fixed interest rate. The
transaction costs related to this transaction are reported as deferred charges
on the balance sheet and are being amortized over the remaining life of the
leases. Oglethorpe's future rental payments 

                                             53


under its leases will vary from amounts shown in the table above to the extent 
that the actual interest rates associated with the debt of the lessors varies 
from the 11.05% debt rate assumed in the table.
 
    The Scherer Unit No. 2 lease meets the definitional criteria to be reported
on Oglethorpe's balance sheets as a capital lease. For rate-making purposes,
however, Oglethorpe treats this lease as an operating lease; that is, Oglethorpe
considers the actual rental payment on the leased asset in its cost of service.
Oglethorpe's accounting treatment for this capital lease has been modified,
therefore, to reflect its rate-making treatment. Interest expense is applied to
the obligation under the capital lease; then, amortization of the leasehold is
recognized, such that interest and amortization equal the actual rental payment.
Through 1994, the level of actual rental payments was such that amortization of
the Scherer Unit No. 2 leasehold calculated in this manner was less than zero.
Thereafter, the scheduled cash rental payments increase such that positive
amortization of the leasehold occurs and the entire cost of the leased asset is
recovered through the rate-making process. The difference in the amortization
recognized in this manner on the statements of revenues and expenses and the
straight-line amortization of the leasehold is reflected on Oglethorpe's balance
sheets as a deferred charge.
 
    In 1991 and 1992, all four of the lessors received Notices of Proposed 
Adjustments from the IRS proposing adjustments to the tax benefits claimed by 
these lessors in connection with their purchase and ownership of an undivided 
interest in Scherer Unit No 2. In 1994, the IRS issued a revised Notice of 
Proposed Adjustments to one of the lessors which reduced the proposed 
adjustments. During 1995, this lessor advised Oglethorpe that it had settled 
this issue on the basis of the revised Notice of Proposed Adjustments. 
Oglethorpe subsequently made a lump sum indemnity payment of $362,000 to the 
lessor in order to compensate for the reduction in the lessor's tax benefits 
resulting from the sale and leaseback transaction. The IRS has indicated that 
it will take consistent positions with the other three lessors. If the IRS's 
current positions regarding the sale and leaseback transactions were 
ultimately upheld, Oglethorpe would be required to indemnify the other three 
lessors. Oglethorpe's indemnification liability to the three lessors is 
estimated to be approximately $1,391,000 as of December 31, 1997. This 
liability has been reflected on the accompanying balance sheet.
 
5. LONG-TERM DEBT:
 
    Long-term debt consists of mortgage notes payable to the United States of
America acting through the FFB and the RUS, mortgage notes issued in conjunction
with the sale by public authorities of PCBs, and mortgage notes payable to
CoBank. Oglethorpe's headquarters facility is pledged as collateral for the
CoBank headquarters note; substantially all of the owned tangible and certain of
the intangible assets of Oglethorpe are pledged as collateral for the FFB and
RUS notes, the remaining CoBank notes and the notes issued in conjunction with
the sale of PCBs. The detail of the notes is included in the statements of
capitalization.
 
    As part of the Corporate Restructuring effective April 1, 1997, 16.86% of
the then outstanding PCBs was assumed by GTC. Because Oglethorpe was not legally
released from its obligation to pay this debt, the entire debt is shown in the
Statement of Capitalization as a liability of Oglethorpe with an offsetting
amount reflecting the portion assumed by GTC.
 
    In connection with the Corporate Restructuring in March 1997, Oglethorpe
defeased approximately $92,000,000 in principal amount of Series 1992 PCBs.
Initially these bonds have been defeased with the proceeds from the issuance of
approximately $92,000,000 in commercial paper. Oglethorpe has a plan in place to
refinance the commercial paper issuance with a medium-term loan in 1998 and
ultimately expects to refinance the loan with an issuance of PCBs at some point
in the future.
 
    In connection with the Corporate Restructuring in March 1997, Oglethorpe
refinanced $216,925,000 (includes portion assumed by GTC) in principal amount of
Series 1992A PCBs through the issuance of Series 1997A PCBs which matured on
December 1, 1997, which in turn were refunded through the issuance of Series
1997B PCBs which will mature on May 28, 1998 (the Series 1997B Bonds).
Oglethorpe has a plan in place and is in the final stages of a debt offering to
refund the Series 1997B Bonds in March 1998 through the issuance of Series 1998A
and Series 1998B PCBs (the Series 1998 Bonds) having a January 1, 2019 maturity.
The Series 1998 Bonds will initially be issued as variable rate bonds and will
be supported by both a municipal bond insurance policy and bank liquidity
agreements. The unamortized transaction costs related to the 1997A PCBs are
reported as deferred charges on the balance sheet and are being amortized over
the twenty-year life of the Series 1998 Bonds.
 
    In December 1997, Oglethorpe completed a current refunding transaction
whereby $14,635,000 (includes portion assumed by GTC) of PCBs were 

                                             54


issued. The proceeds of this transaction were used to retire $14,635,000 of 
existing bonds in January 1998. At December 31, 1997 both the current and 
existing bonds were reported as outstanding debt on the balance sheet. The 
unamortized transaction costs related to this transaction have been reported 
as a deferred charge on the balance sheet and are being amortized over the 
life of the related bonds.
 
    The annual interest requirement for 1998 is estimated to be $242,000,000.

    Maturities for the long-term debt through 2002 are as follows:

    Oglethorpe has a commercial paper program under which it may issue
commercial paper not to exceed a $280,000,000 balance outstanding at any time.
The commercial paper may be used for working capital requirements and for
general corporate purposes. Oglethorpe's commercial paper is backed 100% by
committed lines of credit provided by a group of banks.
 
    As of December 31, 1997, approximately $92,000,000 of commercial paper was
outstanding in connection with the defeasance of the Series 1992 PCBs discussed
above. There was no commercial paper outstanding at December 31, 1996.
 
    Oglethorpe has a $50,000,000 uncommitted short-term line of credit with CFC
and a $30,000,000 committed line of credit with SunTrust Bank, Atlanta
(SunTrust). The maximum combined amount that can be outstanding under these
lines of credit and the commercial paper program at any one time totals
$330,000,000 due to certain restrictions contained in the SunTrust line of
credit agreement. No balance was outstanding on either of these two lines of
credit at either December 31, 1997 or 1996.
 
6. ELECTRIC PLANT AND RELATED AGREEMENTS:
 
    Oglethorpe and Georgia Power Company (GPC) have entered into agreements
providing for the purchase and subsequent joint operation of certain of GPC's
electric generating plants. A summary of Oglethorpe's plant investments and 
related accumulated depreciation as of December 31, 1997 is as follows:

    Oglethorpe, as of December 31, 1997, estimates property additions (including
capitalized interest but excluding nuclear fuel) to be approximately $19,000,000
in 1998, $17,000,000 in 1999 and $15,000,000 in 2000, primarily for replacements
and additions to generation facilities.
 
    Oglethorpe's proportionate share of direct expenses of joint operation of
the above plants is included in the corresponding operating expense captions
(e.g., fuel, production or depreciation) on the accompanying statements of
revenues and expenses.

    7. EMPLOYEE BENEFIT PLANS:

    Oglethorpe has a noncontributory defined benefit pension plan covering 
substantially all employees. Oglethorpe's pension cost was approximately 
$654,000 in 1997, $1,388,000 in 1996 and $1,954,000 in 1995. For 1995, 
pension cost increased by $912,000 related to termination benefits. The 
termination benefits resulted from an early retirement program undertaken in 
the fourth quarter of 1995. Plan benefits are based on years of service and 
the employee's compensation during the last ten years of employment. 
Oglethorpe's funding policy is to contribute annually an amount not less than 
the minimum required by the Internal Revenue Code and not more than the 
maximum tax deductible amount.

    The plan's funded status also reflects Oglethorpe's retention of the 
unfunded pension liability for employees as of the date they were transferred 
to Intellisource Services Solutions in February 1997.

    The plan's pension cost recognized in 1997, 1996 and 1995 was shown as 
follows:

    The discount rate and rate of increase in future compensation levels used 
in determining the actuarial present value of the projected benefit 
obligations shown above were 7.25% and 5.0% in 1997, and 7.5% and 5.0% in 
1996, respectively. The expected long-term rate of return on plan assets was 
8.5% in 1997, 1996 and 1995 and the discount rate used in determining the 
pension expense was 7.5% in 1997, 7.25% in 1996 and 8.5% in 1995.

    Oglethorpe has a contributory employee retirement savings plan covering 
substantially all employees. Employee contributions to the plan may be 
invested in one or more of nine funds. The employee may contribute, subject 
to IRSlimitations, up to 16% of his annual compensation. Oglethorpe will 
match the employee's contribution up to one-half of the first 6% of the 
employee's annual compensation, as long as there is sufficient net margin to 
do so. Oglethorpe's contributions to the plan were approximately $248,000 in 
1997, $561,000 in 1996 and $589,000 in 1995.

    8. NUCLEAR INSURANCE:

    GPC, on behalf of all the co-owners of Plants Hatch and Vogtle, is a 
member of Nuclear Electric Insurance, Ltd. (NEIL), a mutual insurer 
established to provide property damage insurance coverage in an amount up to 
$500,000,000 for members' nuclear generating facilities. In the event that 
losses exceed accumulated reserve funds, the members are subject to 
retroactive assessments (in proportion to their participation in the mutual 
insurer). The portion of the current maximum annual assessment for GPC that 
would be payable by Oglethorpe, based on ownership share, is limited to 
approximately $5,959,000 for each nuclear incident.

    GPC, on behalf of all the co-owners of Plants Hatch and Vogtle, has 
coverage under NEIL II, which provides insurance to cover decontamination, 
debris removal and premature decommissioning as well as excess property 
damage to nuclear generating facilities for an additional $2,250,000,000 for 
losses in excess of the $500,000,000 primary coverage described above. Under 
the NEIL policies, members are subject to retroactive assessments in 
proportion to their participation if losses exceed the accumulated funds 
available to the insurer under the policy. The portion of the current maximum 
annual assessment for GPC that would be payable by Oglethorpe, based on 
ownership share, is limited to approximately $9,563,000.

    For all on-site property damage insurance policies for commercial nuclear 
power plants, the NRC requires that the proceeds of such policies issued or 
annually renewed on or after April 2, 1991 shall be 

                                             56


dedicated first for the sole purpose of placing the reactor in a safe and 
stable condition after an accident. Any remaining proceeds are next to be 
applied toward the costs of decontamination and debris removal operations 
ordered by the NRC, and any further remaining proceeds are to be paid either 
to the company or to its bond trustees as may be appropriate under the 
policies and applicable trust indentures.

    The Price-Anderson Act, as amended in 1988, limits public liability 
claims that could arise from a single nuclear incident to $8,900,000,000, 
which amount is to be covered by private insurance and agreements of 
indemnity with the NRC. Such private insurance (in the amount of $200,000,000 
for each plant, the maximum amount currently available) is carried by GPC for 
the benefit of all the co-owners of Plants Hatch and Vogtle. Agreements of 
indemnity have been entered into by and between each of the co-owners and the 
NRC. In the event of a nuclear incident involving any commercial nuclear 
facility in the country involving total public liability in excess of 
$200,000,000, a licensee of a nuclear power plant could be assessed a 
deferred premium of up to $79,275,000 per incident for each licensed reactor 
operated by it, but not more than $10,000,000 per reactor per incident to be 
paid in a calendar year. On the basis of its sell-back adjusted ownership 
interest in four nuclear reactors, Oglethorpe could be assessed a maximum of 
$95,130,000 per incident, but not more than $12,000,000 in any one year.

    All retrospective assessments, whether generated for liability or 
property, may be subject to applicable state premium taxes.

    9. POWER PURCHASE AND SALE AGREEMENTS:

    Oglethorpe is utilizing long-term power marketer arrangements to reduce 
the cost of power to the Members. Oglethorpe has entered into power marketer 
agreements with LG&E Energy Marketing, Inc. (LEM) effective January 1, 1997, 
for approximately 50% of the load requirements of the Members and with Morgan 
Stanley, effective May 1, 1997, with respect to 50% of the Members' then 
forecasted load requirements. These agreements extend through 2011 and into 
2005, respectively. The LEM agreements are based on the actual requirements 
of the Members during the contract term, whereas the Morgan Stanley agreement 
represents a fixed supply obligation. Under these power marketer agreements, 
Oglethorpe purchases energy at fixed prices covering a portion of the costs 
of energy to its Members. LEM and Morgan Stanley, in turn, have certain 
rights to market excess energy from the Oglethorpe system. All of 
Oglethorpe's existing generating facilities and power purchase arrangements 
are available for use by LEM and Morgan Stanley for the term of the 
respective agreements. Oglethorpe continues to be responsible for all of the 
costs of its system resources but receives payment from LEM and Morgan 
Stanley for the use of the resources. The Morgan Stanley agreement requires 
both Oglethorpe and Morgan Stanley to make minimum purchases from each other, 
however, the net requirement between the parties is immaterial. Under the LEM 
agreement there is no minimum purchase required.

    Oglethorpe has entered into long-term power purchase agreements with GPC, 
Big Rivers Electric Corporation (Big Rivers), and Entergy Power, Inc. (EPI). 
Under the agreement with GPC, Oglethorpe purchased on a take-or-pay basis 
1,000 megawatts (MW) of capacity through the period ending August 31, 1997. 
Effective September 1, 1997, Oglethorpe will purchase 750 MW of capacity 
through the period ending August 31, 1998. Effective September 1, 1998, 
Oglethorpe will purchase 500 MW of capacity through the period ending August 
31, 1998. Effective September 1, 1999, Oglethorpe will purchase 250 MW of 
capacity through the period ending December 31, 2003, subject to reductions 
or extension with proper notice. The Big Rivers agreement commenced in August 
1992 and is effective through July 2002. Oglethorpe is obligated under this 
agreement to purchase on a take-or-pay basis 100 MW of firm capacity and 
certain minimum energy amounts associated with that capacity. The EPI 
agreement commenced in July 1992, has a term of ten years and represents a 
take-or-pay commitment by Oglethorpe to purchase 100 MW of capacity.

    Oglethorpe has a contract with Hartwell Energy Limited Partnership for 
the purchase of approximately 300 MW of capacity for a 25-year period 
commencing in April 1994.

    Oglethorpe has entered into a short-term seasonal power purchase 
agreement with Florida Power Corporation. Under the agreement, Oglethorpe 
purchased 50 MW of capacity on a take-or-pay basis for the period June 1, 
1997 through September 30, 1997 and will purchase 275 MW for the period June 
1, 1998 through September 30, 1998.

    As of December 31, 1997, Oglethorpe's minimum purchase commitments under 
the above agreements, without regard to capacity reductions or adjustments 
for changes in costs, for the next five years are as follows:

1999................................................          84,578

                                             57


    Oglethorpe's power purchases from these agreements amounted to 
approximately $175,818,000 in 1997, $190,760,000 in 1996 and $206,641,000 in 
1995.

    Oglethorpe has entered into an agreement with Alabama Electric 
Cooperative to sell 100 MW of capacity for the period June 1998 through 
December 2005.

    10. QUARTERLY FINANCIAL DATA (UNAUDITED):

    Summarized quarterly financial information for 1997 and 1996 is as follows:



                                              FIRST        SECOND       THIRD       FOURTH

1997
  Operating revenues....................... $ 271,485    $ 242,876   $ 286,579     $ 246,912

  Net margin...............................     9,436        5,510        (872)        8,331

1996
  Operating revenues....................... $ 270,689    $ 275,228   $ 286,648     $ 268,872
  Operating margin.........................    73,568       72,514      75,009        61,658
  Net margin...............................     8,988        4,732      12,508        (4,476)


    Oglethorpe's business is influenced by seasonal weather conditions. The 
negative net margin for the third quarter of 1997 reflects a $4,000,000 
reduction in revenue requirement approved by Oglethorpe's Board of Directors. 
Such reduction in revenues was implemented by reducing the capacity charges 
billed to Members in August 1997. The negative net margin for the fourth 
quarter of 1996 is consistent with expectations and reflects recognition of 
certain nonrecurring expenses.

    11. CORPORATE RESTRUCTURING

    Oglethorpe and the Members completed on March 11, 1997, a Corporate 
Restructuring in which Oglethorpe, effective April 1, 1997, was divided into 
three specialized operating companies. Oglethorpe's transmission business was 
sold to, and is now owned and operated by GTC. Oglethorpe's system operations 
business was sold to, and is now owned and operated by GSOC. Oglethorpe 
continues to own and operate its power supply business.

    The total purchase price GTC and GSOC paid Oglethorpe for the 
transmission and system operations business was approximately $717 million. 
The following summarizes the assets and liabilities sold by Oglethorpe to GTC 
and GSOC as a result of the restructuring:

    In addition, Oglethorpe also made a special patronage capital 
distribution to the Members which was used by the Members to establish equity 
in and to provide working capital to GTC.

    The following unaudited pro forma statement of revenues and expenses for 
the year ended December 31, 1997 reflects the operations of Oglethorpe as 
reported and restated, reflecting the exclusion of the transmission and 
system operations businesses as though the Corporate Restructuring had 
occurred at the beginning of 1997.

REPORT OF MANAGEMENT

    The management of Oglethorpe Power Corporation has prepared this report 
and is responsible for the financial statements and related information. 
These statements were prepared in accordance with generally accepted 
accounting principles appropriate in the circumstances and necessarily 
include amounts that are based on best estimates and judgments of management. 
Financial information throughout this annual report is consistent with the 
financial statements.

    Oglethorpe maintains a system of internal accounting controls to provide 
reasonable assurance that assets are safeguarded and that the books and 
records reflect only authorized transactions. Limitations exist in any system 
of internal control based upon the recognition that the cost of the system 
should not exceed its benefits. Oglethorpe believes that its system of 
internal accounting control, together with the internal auditing function, 
maintains appropriate cost/benefit relations.

    Oglethorpe's system of internal controls is evaluated on an ongoing basis 
by its qualified internal audit staff. The Corporation's independent public 
accountants (Coopers & Lybrand L.L.P.) also consider certain elements of the 
internal control system in order to determine their auditing procedures for 
the purpose of expressing an opinion on the financial statements.

    Coopers & Lybrand L.L.P. also provides an objective assessment of how 
well management meets its responsibility for fair financial reporting. 
Management believes that its policies and procedures provide reasonable 
assurance that Oglethorpe's operations are conducted with a high standard of 
business ethics. In management's opinion, the financial statements present 
fairly, in all material respects, the financial position, results of 
operations, and cash flows of Oglethorpe.

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

    To the Board of Directors of Oglethorpe Power Corporation: 

    We have audited the accompanying balance sheets and statements of 
capitalization of Oglethorpe Power Corporation (a Georgia corporation) as of 
December 31, 1997 and 1996 and the related statements of revenues and 
expenses, patronage capital, and cash flows for each of the three years in 
the period ended December 31, 1997. These financial statements are the 
responsibility of Oglethorpe's management. Our responsibility is to express 
an opinion on these financial statements based on our audits.

    We conducted our audits in accordance with generally accepted auditing 
standards. Those standards require that we plan and perform the audit to 
obtain reasonable assurance about whether the financial statements are free 
of material misstatement. An audit includes examining, on a test basis, 
evidence supporting the amounts and disclosures in the financial statements. 
An audit also includes assessing the accounting principles used and 
significant estimates made by management, as well as evaluating the overall 
financial statement presentation. We believe that our audits provide a 
reasonable basis for our opinion.

    In our opinion, the financial statements referred to above present 
fairly, in all material respects, the financial position of Oglethorpe Power 
Corporation as of December 31, 1997 and 1996 and the results of its 
operations and its cash flows for each of the three years in the period ended 
December 31, 1997, in conformity with generally accepted accounting 
principles.

                                    PART III
 
ITEM 10. DIRECTORS AND EXECUTIVE OFFICERS OF THE REGISTRANT
 
    As part of the Corporate Restructuring, Oglethorpe amended its Bylaws to
provide for an eleven member board of directors consisting of six directors
elected from the Members (the "Member Directors"), four independent outside
directors (the "Outside Directors") and Oglethorpe's President and Chief
Executive Officer. Each Member Director must be a director or general manager of
an Oglethorpe Member. Five of the six Member Directors must be located in each
of five geographical regions of the State of Georgia. The sixth Member Director
is elected statewide. None of the four Outside Directors may be a director,
officer or employee of GTC, GSOC or any Member. All eleven directors are
nominated by representatives from each Member whose weighted nomination is based
on the number of retail customers served by each Member. After nomination, the
directors are elected by a majority vote of each Member, voting on a one-Member,
one-vote basis.
 
    The Bylaws provide for staggering the terms of the Member Directors and
Outside Directors by dividing the number of directors into three groups. As
noted below, some of the directors were elected to an initial term of one year,
some two years and some three years. As these initial terms expire, directors
will thereafter be elected for a term of three years.
 
    Oglethorpe is managed and operated under the direction of a President and
Chief Executive Officer, who is appointed by the Board of Directors. The Senior
Officers and Directors of Oglethorpe and significant employees of subsidiaries
of Oglethorpe are as follows:
