BG Group said it will sell three of its North American combined cycle gas turbine power plants to Energy Capital Partners for $450m.

The gas-fired plants include the 168MW Dighton power plant, the 264MW Masspower power plant at Massachusetts and the 812MW Lake Road power plant at Connecticut.

The 168MW Dighton power plant at Dighton, Massachusetts, was commissioned in 1999 and purchased by BG in 2006.

The three-unit Lake Road plant with the generation capacity 812MW became operational in 2002 and had been acquired by BG group in March 2007.

The 264MW Masspower power plant started operations in 1993 and was bought by the firm in May 2007.

Energy Capital has formed a new firm to own and operate the power plants after the transaction has been completed.
