Exhibit 4.13.1

                               INDEMNITY AGREEMENT

      THIS INDEMNITY AGREEMENT (this "Indemnity Agreement"), dated as of March
1, 1997, is made by and between GEORGIA TRANSMISSION CORPORATION (AN ELECTRIC
MEMBERSHIP CORPORATION) ("GTC") and OGLETHORPE POWER CORPORATION (AN ELECTRIC
MEMBERSHIP GENERATION & TRANSMISSION CORPORATION) ("OPC").

                                    RECITALS

      The Authorities have issued the Bonds on behalf of OPC and have loaned the
proceeds of the sale of the Bonds to OPC pursuant to the Loan Agreements and the
Notes (as all such terms are defined below). OPC's payment obligations under the
Loan Agreements and the Notes are secured under OPC's Consolidated Mortgage and
Security Agreement, dated as of September 1, 1994, made by and among OPC, as
mortgagor, and the United States of America (the "Government"), acting through
the Administrator of the Rural Utilities Service (as successor to the powers of
the Rural Electrification Administration), CoBank, ACB (formerly known as the
National Bank for Cooperatives) ("CoBank"), Credit Suisse, acting by and through
its New York Branch (the "Credit Bank"), and SunTrust Bank, Atlanta (formerly
known as Trust Company Bank), as trustee (the "Trustees") under the Bond
Indentures (as defined below), as mortgagees (as such instrument may be amended,
modified, supplemented, restated, consolidated or replaced, the "OPC Mortgage").
Pursuant to the OPC Mortgage, OPC has granted the mortgagees a lien on
substantially all of its assets, including the assets which comprise its
transmission business.

      OPC, GTC and Georgia System Operations Corporation ("GSOC") have entered
into an Second Amended and Restated Restructuring Agreement, dated as of
February 24, 1997 (as it may have been or may be amended from time to time, the
"Restructuring Agreement"), under which OPC has agreed to transfer its
transmission business, including its transmission assets, to GTC (OPC has also
agreed pursuant to the Restructuring Agreement to transfer its system operations
business, including its system operations assets, to GSOC). The purchase price
to be paid by GTC to OPC pursuant to the Restructuring Agreement for the
transmission business will be paid by: (i) GTC's assumption of a pro rata
portion of OPC's existing obligations secured under the OPC Mortgage, including
a portion of OPC's payment obligations under the Loan Agreements, the Notes and
the Related Financial Arrangements (as such term is defined below); (ii) GTC's
assumption of certain transmission liabilities; and (iii) the remainder in cash.
To evidence GTC's assumption of a portion of OPC's payment obligations on the
Loan Agreements and the Notes, GTC has entered into Assumption Agreements, dated
of even date herewith, for the benefit of each of the Trustees (collectively,
the "Assumption Agreements"). GTC and OPC are entering into this Indemnity
Agreement to set forth their respective rights and obligations with respect to
the Bonds, the Loan Agreements, the Notes, the Assumption Agreements and the
Related Financial Arrangements.


      GTC has entered into an Indenture with SunTrust Bank, Atlanta, dated as of
March 1, 1997 (as such instrument may be amended, modified, supplemented,
restated, consolidated or replaced, the "GTC Indenture"), and has secured under
the GTC Indenture its obligations pursuant to the Assumption Agreements. GTC has
granted a lien on substantially all of its assets which comprise its
transmission business pursuant to the GTC Indenture, including the transmission
assets transferred to it by OPC.

consideration, the receipt and sufficiency of which are hereby acknowledged, OPC
and GTC agree as follows:

      SECTION 4. Prepayment and Acceleration of Assumption Obligations.

            (a) Pursuant to the Assumption Agreements, GTC has the right at any
      time to prepay its assumption obligations under the Loan Agreements and
      the Notes with respect to any maturity of any issue of the Bonds. OPC
      agrees to take all action reasonably requested by GTC to permit GTC to
      exercise such right of prepayment; provided, that (i) GTC shall reimburse
      OPC for any expenses incurred by OPC in connection therewith and (ii) OPC
      shall not be required, and GTC shall not be permitted, to take any action
      that would (A) cause the interest earned by holders of any of the Bonds to
      become taxable under federal income tax law or (B) have an adverse
      economic impact on OPC (unless GTC fully reimburses OPC in connection with
      any such adverse economic impact).

            (b) Pursuant to the Loan Agreements and the Notes, OPC has the right
      at certain times to prepay its obligations with respect to any maturity of

      that (i) OPC shall reimburse GTC for any expenses incurred by GTC in
      connection therewith, (ii) OPC shall be responsible for the premiums, if
      any, due with respect to such prepayment (unless GTC shall have previously
      prepaid its assumption obligation with respect to such maturity of such
      issue of the Bonds), and (iii) GTC shall have the right to elect to fund
      its prepayment through an assumption of a corresponding amount of any
      refunding indebtedness issued by OPC in connection with such prepayment of
      the Bonds if such assumption would not result in the interest earned by
      any of the holders of the refunding indebtedness being taxable under
      federal income tax law, such assumption to be evidenced in agreements in
      the form of this Indemnity Agreement and the Assumption Agreements.

      SECTION 5. Related Financial Arrangements. GTC agrees to assume, and to
the extent reasonably possible obtain OPC's release as to, the GTC Assumption
Percentage of all obligations under and with respect to any Related Financial
Arrangement with respect to each maturity of each issue of the Bonds, including
obligations for the payment of swap amounts and applicable termination payments
due under interest rate swap agreements, and all fees, expenses and


                                       4


other charges due with respect to any credit and liquidity facilities. To the
extent that OPC is not released from any such obligations to be assumed by GTC,
GTC agrees to be liable for and to indemnify OPC with respect to the GTC
Assumption Percentage of such obligations and, in the event OPC makes a payment
on such obligations which pursuant to this Section 5 is to be made by GTC, GTC
immediately shall reimburse OPC in same day funds with interest equal to the
lesser of (i) the maximum rate lawfully payable, or (ii) the variable prime rate
as announced by SunTrust Bank, Atlanta or any other bank mutually agreed to by
the parties.

      SECTION 6. Security; Term. GTC's obligations under the Assumption
Agreements are secured under the GTC Indenture. In the event GTC fulfills all of
its obligations under this Indemnity Agreement by making all of the payments
provided for herein and in the Assumption Agreements, this Indemnity Agreement
shall be canceled and OPC shall execute such documents and instruments as may be
requested by GTC to evidence or effect the foregoing.

      SECTION 7. Further Assurances. If at any time any further actions are
necessary or desirable to evidence or effect the indemnity and agreements
contemplated by this Indemnity Agreement, or otherwise to carry out the purposes
and provisions of this Indemnity Agreement, each of OPC and GTC shall take such
action and execute and deliver such instruments as are necessary or desirable to
evidence and effect the indemnity and agreements contemplated hereby and

      SECTION 8. Binding Effect. This Indemnity Agreement shall inure to the
benefit of, and shall be binding upon, each of OPC and GTC and their respective
successors and assigns. This Indemnity Agreement may not be assigned without the
consent of all parties.

      SECTION 9. Severability. If any provision of this Indemnity Agreement
shall be held invalid or unenforceable by any court of competent jurisdiction,
such holding shall not invalidate or render unenforceable any other provision
hereof.

      SECTION 10. Effectiveness. The effectiveness of this Indemnity Agreement
and the parties obligations hereunder shall commence on the "Effective Date" as
defined in the Restructuring Agreement.

      SECTION 11. Execution Counterparts. This Indemnity Agreement may be
simultaneously executed in several counterparts, each of which shall be an
original and all of which shall constitute one and the same instrument.
