         .........THIS TWENTIETH SUPPLEMENTAL INDENTURE is made as of the 23rd
day of January, 2004, by and between GEORGIA POWER COMPANY, a Georgia
corporation, 241 Ralph McGill Boulevard, N.E., Atlanta, Georgia 30308-3374 (the
"Company"), and JPMORGAN CHASE BANK, a New York banking corporation, 4 New York
Plaza, New York, New York 10004 (the "Trustee").

                              W I T N E S S E T H:

         .........WHEREAS, the Company has heretofore entered into a Senior Note
Indenture, dated as of January 1, 1998 (the "Original Indenture"), with JPMorgan
Chase Bank (formerly known as The Chase Manhattan Bank), as heretofore
supplemented;

         .........WHEREAS, the Original Indenture is incorporated herein by this
reference and the Original Indenture, as heretofore supplemented and as further
supplemented by this Twentieth Supplemental Indenture, is herein called the
"Indenture";

         .........WHEREAS, under the Original Indenture, a new series of Senior
Notes may at any time be established by the Board of Directors of the Company in
accordance with the provisions of the Original Indenture and the terms of such
series may be described by a supplemental indenture executed by the Company and
the Trustee;

         .........WHEREAS, the Company proposes to create under the Indenture a
new series of Senior Notes;

         .........WHEREAS, additional Senior Notes of other series hereafter
established, except as may be limited in the Original Indenture as at the time
supplemented and modified, may be issued from time to time pursuant to the
Indenture as at the time supplemented and modified; and

         .........WHEREAS, all conditions necessary to authorize the execution
and delivery of this Twentieth Supplemental Indenture and to make it a valid and
binding obligation of the Company have been done or performed.

         .........NOW, THEREFORE, in consideration of the agreements and
obligations set forth herein and for other good and valuable consideration, the
sufficiency of which is hereby acknowledged, the parties hereto hereby agree as
follows:


                               ARTICLE 1.........

                              Series T Senior Notes

         SECTION 101. Establishment. There is hereby established a new series of
Senior Notes to be issued under the Indenture, to be designated as the Company's
Series T 5.75% Senior Public Income Notes due January 15, 2044 (the "Series T
Notes").

         There are to be authenticated and delivered $100,000,000 principal
amount of Series T Notes, and such principal amount of the Series T Notes may be
increased from time to time pursuant to Section 301 of the Original Indenture.
All Series T Notes need not be issued at the same time and such series may be
reopened at any time, without the consent of any Holder, for issuances of
additional Series T Notes. Any such additional Series T Notes will have the same
interest rate, maturity and other terms as those initially issued. No Series T
Notes shall be authenticated and delivered in excess of the principal amount as
so increased except as provided by Sections 203, 303, 304, 907 or 1107 of the
Original Indenture. The Series T Notes shall be issued in definitive fully
registered form.

         The Series T Notes shall be issued in the form of one or more Global
Securities in substantially the form set out in Exhibit A hereto. The Depositary
with respect to the Series T Notes shall be The Depository Trust Company.

         The form of the Trustee's Certificate of Authentication for the Series
T Notes shall be in substantially the form set forth in Exhibit B hereto.

         Each Series T Note shall be dated the date of authentication thereof
and shall bear interest from the date of original issuance thereof or from the
most recent Interest Payment Date to which interest has been paid or duly
provided for.

         SECTION 102. Definitions. The following defined terms used herein
shall, unless the context otherwise requires, have the meanings specified below.
Capitalized terms used herein for which no definition is provided herein shall
have the meanings set forth in the Original Indenture.

         "Interest Payment Dates" means January 15, April 15, July 15 and
October 15 of each year, commencing on April 15, 2004.

         "Original Issue Date" means January 23, 2004.

         "Regular Record Date" means, with respect to each Interest Payment
Date, the close of business on the 15th calendar day preceding such Interest
Payment Date (whether or not a Business Day).

         "Stated Maturity" means January 15, 2044.

         SECTION 103. Payment of Principal and Interest. The principal of the
Series T Notes shall be due at Stated Maturity (unless earlier redeemed). The
unpaid principal amount of the Series T Notes shall bear interest at the rate of
5.75% per annum until paid or duly provided for. Interest shall be paid
quarterly in arrears on each Interest Payment Date to the Person in whose name
the Series T Notes are registered on the Regular Record Date for such Interest
Payment Date, provided that interest payable at the Stated Maturity of principal
or on a Redemption Date as provided herein will be paid to the Person to whom
principal is payable. Any such interest that is not so punctually paid or duly
provided for will forthwith cease to be payable to the Holders on such Regular
Record Date and may either be paid to the Person or Persons in whose name the
Series T Notes are registered at the close of business on a Special Record Date
for the payment of such defaulted interest to be fixed by the Trustee, notice
whereof shall be given to Holders of the Series T Notes not less than ten (10)
days prior to such Special Record Date, or be paid at any time in any other
lawful manner not inconsistent with the requirements of any securities exchange,
if any, on which the Series T Notes shall be listed, and upon such notice as may
be required by any such exchange, all as more fully provided in the Original
Indenture.

         Payments of interest on the Series T Notes will include interest
accrued to but excluding the respective Interest Payment Dates. Interest
payments for the Series T Notes shall be computed and paid on the basis of a
360-day year of twelve 30-day months. In the event that any date on which
interest is payable on the Series T Notes is not a Business Day, then a payment
of the interest payable on such date will be made on the next succeeding day
that is a Business Day (and without any interest or other payment in respect of
any such delay), with the same force and effect as if made on the date the
payment was originally payable.

         Payment of the principal and interest due at the Stated Maturity or
earlier redemption of the Series T Notes shall be made upon surrender of the
Series T Notes at the Corporate Trust Office of the Trustee. The principal of
and interest on the Series T Notes shall be paid in such coin or currency of the
United States of America as at the time of payment is legal tender for payment
of public and private debts. Payments of interest (including interest on any
Interest Payment Date) will be made, subject to such surrender where applicable,
at the option of the Company, (i) by check mailed to the address of the Person
entitled thereto as such address shall appear in the Security Register or (ii)
by wire transfer or other electronic transfer at such place and to such account
at a banking institution in the United States as may be designated in writing to
the Trustee at least sixteen (16) days prior to the date for payment by the
Person entitled thereto.

         SECTION 104. Denominations. The Series T Notes may be issued in the
denominations of $25, or any integral multiple thereof.

         SECTION 105. Global Securities. The Series T Notes will be issued in
the form of one or more Global Securities registered in the name of the
Depositary (which shall be The Depository Trust Company) or its nominee. Except
under the limited circumstances described below, Series T Notes represented by
one or more Global Securities will not be exchangeable for, and will not
otherwise be issuable as, Series T Notes in definitive form. The Global
Securities described above may not be transferred except by the Depositary to a
nominee of the Depositary or by a nominee of the Depositary to the Depositary or
another nominee of the Depositary or to a successor Depositary or its nominee.

         Owners of beneficial interests in such a Global Security will not be
considered the Holders thereof for any purpose under the Indenture, and no
Global Security representing a Series T Note shall be exchangeable, except for
another Global Security of like denomination and tenor to be registered in the
name of the Depositary or its nominee or to a successor Depositary or its
nominee. The rights of Holders of such Global Security shall be exercised only
through the Depositary.

         A Global Security shall be exchangeable for Series T Notes registered
in the names of persons other than the Depositary or its nominee only if (i) the
Depositary notifies the Company that it is unwilling or unable to continue as a
Depositary for such Global Security and no successor Depositary shall have been
appointed by the Company, or if at any time the Depositary ceases to be a
clearing agency registered under the Securities Exchange Act of 1934, as
amended, at a time when the Depositary is required to be so registered to act as
such Depositary and no successor Depositary shall have been appointed by the
Company, in each case within 90 days after the Company receives such notice or
becomes aware of such cessation, (ii) the Company in its sole discretion
determines that such Global Security shall be so exchangeable, or (iii) there
shall have occurred an Event of Default with respect to the Series T Notes. Any
Global Security that is exchangeable pursuant to the preceding sentence shall be
exchangeable for Series T Notes registered in such names as the Depositary shall
direct.

         SECTION 106. Transfer. No service charge will be made for any transfer
or exchange of Series T Notes, but payment will be required of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
therewith.

         The Company shall not be required (a) to issue, transfer or exchange
any Series T Notes during a period beginning at the opening of business fifteen
(15) days before the date of the mailing of a notice pursuant to Section 1104 of
the Original Indenture identifying the serial numbers of the Series T Notes to
be called for redemption, and ending at the close of business on the day of the
mailing, or (b) to transfer or exchange any Series T Notes theretofore selected
for redemption in whole or in part, except the unredeemed portion of any Series
T Notes redeemed in part.

         SECTION 107. Redemption at the Company's Option. The Series T Notes
shall be subject to redemption at the option of the Company at any time, in
whole or, from time to time, in part, without premium or penalty, on or after
January 23, 2009, at a Redemption Price equal to 100% of the principal amount of
the Series T Notes to be redeemed plus accrued but unpaid interest on the Series
T Notes to the Redemption Date.

         In the event of redemption of the Series T Notes in part only, a new
Series T Note or Notes for the unredeemed portion will be issued in the name or
names of the Holders thereof upon the surrender thereof.

         The Series T Notes will not have a sinking fund.

         Notice of redemption shall be given as provided in Section 1104 of the
Original Indenture.

         Any redemption of less than all of the Series T Notes shall, with
respect to the principal thereof, be divisible by $25.


                                    ARTICLE 2

                            Miscellaneous Provisions

         SECTION 201. Recitals by Company. The recitals in this Twentieth
Supplemental Indenture are made by the Company only and not by the Trustee, and
all of the provisions contained in the Original Indenture in respect of the
rights, privileges, immunities, powers and duties of the Trustee shall be
applicable in respect of Series T Notes and of this Twentieth Supplemental
Indenture as fully and with like effect as if set forth herein in full.

         SECTION 202. Ratification and Incorporation of Original Indenture. As
heretofore supplemented and as supplemented hereby, the Original Indenture is in
all respects ratified and confirmed, and the Original Indenture as heretofore
supplemented and as supplemented by this Twentieth Supplemental Indenture shall
be read, taken and construed as one and the same instrument.

         SECTION 203. Executed in Counterparts. This Twentieth Supplemental
Indenture may be simultaneously executed in several counterparts, each of which
shall be deemed to be an original, and such counterparts shall together
constitute but one and the same instrument.

provisions permitting the Holders of specified percentages in principal amount
of the Notes of each series at the time Outstanding, on behalf of the Holders of
all Notes of such series, to waive compliance by the Company with certain
provisions of the Indenture and certain past defaults under the Indenture and
their consequences. Any such consent or waiver by the Holder of this Note shall
