Exhibit No. 1

                              BRITISH ENERGY plc



               CLOSING OF DISPOSAL OF 50% INTEREST IN AMERGEN



The Board of British Energy announced that British Energy and certain of its
subsidiaries yesterday completed the disposal to Exelon Generation Company, LLC
(Exelon) of British Energy's entire 50% interest in AmerGen Energy Company LLC,
(AmerGen).  At closing, British Energy received initial consideration of
approximately US$277m prior to adjustments relating to working capital levels,
unspent nuclear fuel, capital expenditures and low-level waste disposal costs to
be determined at the time of closing.

British Energy will be paying a break fee of US$8.295m to FPL Group, Inc (FPL)
as a result of yesterday's completion.  This follows the termination of the
original sale agreement between British Energy and FPL as a result of Exelon
exercising its right of first refusal.



Approximately GBP94m of the consideration will be used to pay down all current
outstandings under the Government Credit Facility. The Government Credit
Facility will, in accordance with the terms of the temporary increase of GBP75m
granted on 27 November 2003 be reduced to GBP200m. The remaining consideration
will be used for general working capital and collateral purposes.
