Irish utility ESB has acquired the proposed Mynydd y Betws Wind Farm project in South Wales from energy company, Eco2.
Work on the 15 turbine, 34.5MW wind farm is expected to begin in 2011.
Eco2 has developed the Myndd y Betws site along with local private shareholders and is fully licensed.
"ESB is delivering on its strategic objectives to become a significant investor in the UK renewables market," ESB head of wind development in Britain, Andy Paine, said.
Eco2 said the sale allows Eco2 to invest funds into its other businesses including its development of a Welsh tidal business.
