PowerGen's 900 MW combined cycle gas turbine (CCGT) power station at Killingholme achieved full load output over two months before the scheduled date for full commercial load and less than 34 months after the turnkey contract was placed. This paper reviews the development of PowerGen's first CCGT power station, discusses the reasons for the choice of this type of plant and examines early operating experience. The contract strategy, a technical description of the plant, the project programme and the environmental impact of the plant relative to a conventional coal-fired power station are also included.
