The plant was developed under a unique industrial partnership between EDF and GE . The unit was constructed with the first commercial GE 9HA gas turbine , a machine that has some remarkable capabilities beyond just high efficiency. The plant can go from startup to combined cycle operation in less than 25 minutes. It can also be turned down to as low as 30% of its top generating capability while still meeting emission requirements. The flexibility is important for the industry’s ongoing efforts to increase the use of renewable energy and protect the environment.
