 Four of them are 50-MWe gas turbine (GT) units, and the fifth is a 68-MWe steam cycle unit.The entire arrangement is known as combined cycle 4-on-1 where the exhaust from the 4 GT's creates steam via Heat Recovery Steam Generators (HRSGs) to power a single steam turbine.In 2014, the gas fired portion of the plant known as the "Big Hanaford Plant" was removed from the plant footprint and parted out to various buyers.
