THE gas and electricity group Centrica is examining a £10 billion bid for British Energy (BE), the nuclear power company that last week confirmed it was in talks with potential suitors.

Centrica, led by chief executive Sam Laidlaw, hopes it can provide a “British solution” to the future of British Energy, which has been evaluating partners for some months.

However, senior sources at Centrica say the company may lack the firepower to see off rivals, thought to include France’s EDF, Germany’s RWE and Spain’s Iberdrola.

Centrica’s stock market value is just short of £11 billion, but its shares have dropped this year as concerns over high energy prices and fears – which have proved unfounded – that the government would introduce a windfall tax on energy firms.

Centrica shares closed last week at 297p, down 17% over the last three months. In that period period they have underperformed the FTSE All Share by 3.3%. Bankers also believe the credit crisis means the group might struggle to raise the cash necessary for a successful bid.

The debate over BE comes against a backdrop of rapid consolidation among European ulili-ties. EDF is reported this weekend to be in talks to team up with Spain’s ACS (Actividades de Construcción y Servicios) to bid for Iberdrola (Spain’s largest utility group), and Union Fenosa, No 3 in the market. Together the deals would be worth about $134 billion (£68 billion).

BE’s future could be resolved within the next few months. Having been forced to seek a government bail-out six years ago, when it was squeezed by a drastic drop in electricity prices, it has since enjoyed a revival.

The company’s shares were up last week, closing at 621p, valuing the group at £6.4 billion.

It is a key player in the government’s plans for a new fleet of nuclear power stations. It owns and operates nearly all of the UK’s operational reactors. New plants are expected to be built at or near existing nuclear sites.

BE began talks with prospective partners for a nuclear construction programme last year, but these have taken on “a more strategic” nature, one source close to the company said.

Last week BE said it was “in discussions with interested parties in the context of its future . . . these discussions could lead to a business combination or an offer for the company”.

BE is being advised by NM Rothschild, the investment bank. The government, which indirectly retains a 35% interest in BE, has recruited UBS.

Ministers are understood to be keen to ensure that BE’s new partner will maintain the current reactors, and work to extend their operating lives. UK gas prices are at record levels for the summer because continental utilities are sucking up supply to replenish their storage facilities. Wholesale prices have reached 51p a therm, compared with 31p last summer.

Laidlaw said: “As an increasing proportion of the gas the UK needs is imported, getting access to European networks is critical.

“Until we see more liberalisa-tion, Europe will continue to use the UK as a main source of gas at short notice - but may not be willing to provide gas to the UK when we most need it.

“The UK faces becoming the ‘gas lender of last resort’ and we are alert to the very real threats that this brings to the UK economy and prices.”
