GE Power Systems has signed an agreement with the Tokyo Electric Power Company (TEPCO) to design and build the first power plant in Asia and the third in the world based on GE’s most advanced combined-cycle technology, the H System.
GE will supply three 109H combined-cycle systems for TEPCO’s Futtsu No 4 project, with each system including an MS9001H gas turbine, a steam turbine and a generator. The combined output of the three systems will be 1520 MWe.
Shipment of the equipment is scheduled to begin in April of 2006 with the first unit expected to begin commercial operation in mid-2008. All three units will be in service by mid-2010.
GE will be the prime contractor for the Futtsu No 4 project. The three 9H gas turbines will be built at GE’s Greenville, SC, manufacturing plant. The gas turbine compressors, steam turbines and generators will be built by Toshiba Corporation at its Keihin facility, under a previously announced agreement with GE. The heat recovery steam generators (HRSGs), de-nitrification systems and accessory equipment will be supplied by Toshiba Corporation and Hitachi Ltd.
The H System is designed to be the first gas turbine combined-cycle system in the world to achieve 60 per cent thermal efficiency.
The world’s first H System combined-cycle plant will be the 480 MWe Baglan Bay power station in South Wales, scheduled to start up in the summer of 2002. Construction began at the site in October of 2000. Following extensive testing in GE’s Greenville plant, the first 9H gas turbine was shipped to Wales in December 2000, and installation of the gas turbine at the Baglan Bay site is currently under way.
The world’s second H System project will be Sithe Energies’ Heritage Station in upstate New York. This 800 MWe plant will use two 7H (60 Hz) gas turbines and is scheduled to enter service in 2004.
