British Energy says it has benefited from higher energy prices

The company, which sells electricity to wholesale customers, said it had benefited from higher energy prices.

British Energy completed a financial rescue deal in 2005, which saw it issue new bonds to creditors in a bid to avoid bankruptcy.

The firm operates eight nuclear power plants and one coal-fired station.

"We have seen rapidly changing energy markets leading to a significant increase in UK power prices over the year," said chairman Sir Adrian Montague. "British Energy has benefited from these price increases".

However, a report in March this year warned that the cost of covering British Energy's nuclear liabilities had gone up by 50%, following a costly government bail-out of the nuclear power generator in 2002.

The National Audit Office said that UK taxpayers faced a "significant risk" of a bill of �5bn.

The government has indicated that it is prepared to sell part of its majority stake in the firm.
