EdF Eyes UK's Seeboard

LCG, Nov. 20, 2001--Electricit de France, fresh from its successful acquisition of a British electric distribution company and a large English power plant from TXU Europe, is said to be interested in purchasing Seeboard, the south-east of England regional electricity company.

EdF already owns London Electricity and the retail business of Sweb, England's southwestern regional electric company. Yesterday the French state-run monopoly announced the purchase of Eastern Energy, Britain's largest electric distribution company, from TXU.

American Electric Power Co. of the U.S. is expected to put Seeboard on the market next year, and Bruno Lescoeur, chief executive of London Electricity, says EdF is interested. "We would definitely be interested in Seeboard if it becomes available," he said.

EdF is Europe's largest electric company and is getting bigger. The acquisition of Seeboard, with London Electricity, Sweb and Eastern Energy already in hand, it would control most of the English power market south of the industrial midlands.
