LONDON – General Electric is considering building wind-energy turbines in Britain as the country prepares to spend $120 billion boosting its offshore wind capacity.

”When you deliver machines of the size and scale of these units you need to be close to where these wind farms are located, so the U.K. is one of the areas that is of interest to us to have a substantial base,” Magued Eldaief, GE Energy’s British manager, said in an interview.

Atlanta-based GE Energy bolstered its access to offshore turbine technology with an agreement to buy ScanWind from Sweden’s Morphic Technologies for $18 million last year.

Britain, already the nation with the most offshore wind capacity, boosted planned developments by 32,200 megawatts in January, adding to the 8,000 megawatts previously awarded. The new farms may contribute more than half the power needed to meet a British goal of getting 15 percent of energy from alternative sources by 2020.

Other turbine makers, including Clipper Windpower and Mitsubishi Corp.’s European power systems unit, have announced plans to boost their presence in Britain. Iberdrola, Spain’s biggest power company, said Thursday that it’s pushing Gamesa Corp. Tecnologica to make wind- energy turbines in Britain.
