.
, an American power firm, and built by Raytheon Engineers and Constructor
and Mitsubishi Heavy Industries
, who provided the gas turbine equipment. The plant entered service in February 2001. It trades as Damhead Creek Ltd.
On June 2 2004, the plant was bought by Scottish Power
for £317 million.
On 9 March 2009 Scottish Power announced plans to develop a second 1,000MW gas-fired power station adjacent to the current power station. It has been named Damhead Creek 2.
type power station that uses natural gas. There are two Mitsubishi 701F gas turbine
s with the exhaust gas from each entering two (Dutch) NEM heat recovery steam generators. The steam from these enters one 216MWe Mitsubishi steam turbine
. There are three hydrogen-cooled electrical generator
s - two on the gas turbines and one on the steam turbine.
