Exhibit       Description

No. 1         RNS Announcement, re:  UPDATE BRUCE A'S REACTORS
              dated  25 June 2003



UPDATE REGARDING DELAYED RESTART OF BRUCE 'A'S TWO REACTORS

Further to its announcement of 13 June 2003 regarding the anticipated dates for
the re-start of Units 3 and 4 at Bruce A, British Energy has been notified by
Bruce Power that there will be further delays in the timing of the restart of
Units 3 and 4.

Bruce Power has informed British Energy that all required submissions in respect
of Unit 4 have been made to the Canadian Nuclear Safety Commission, and that
regulatory approval to the restart of Unit 4 is expected shortly. However Bruce
Power no longer expects to achieve the restart of Unit 4 by 30 June 2003.

Furthermore, as a result of this delay, Bruce Power has notified British Energy
that it now expects Unit 3 will not restart by 30 July 2003.

Under the terms of the sale and purchase agreement announced in December 2002,
if the restart of the two Units is delayed beyond 15 June 2003 and 1 August 2003
respectively, subject to certain exceptions, the consideration of C$50M per Unit
payable to British Energy decreases on a sliding scale falling to zero after 9
months delay.

A further announcement will be made in due course.
