13 October 2006 -- The first of three GE Frame 9H gas turbines is being installed at Tokyo Electric Power Company's (TEPCO) Futtsu Thermal Power Station Group 4, the first Asian application of this type of gas turbine combined-cycle technology for GE.
Three GE 109H systems, each featuring a 9H gas turbine, steam turbine and generator, will be installed at the Futtsu site and will produce a total of 1,520 MW. The three units will enter commercial operation between 2008 and 2010.
GE Energy said the H System will be the world's first combined-cycle system with the capability to reach 60 percent thermal efficiency (LHV basis).
The high efficiency of the H System means less fuel is used resulting in fewer emissions for each megawatt of electricity produced, a GE Energy press release stated. A 9H System has the capability of producing 87,000 metric tons per year fewer greenhouse gasses when compared to a typical gas turbine combined-cycle plant producing the equivalent electricity.
Manufactured at GE Energy's Greenville, South Carolina facility, the first 9H was shipped to Japan in June of this year. It was erected on its base in the Futtsu facility on August 11, followed by the installation of the steam turbine lower pressure casing on August 17. The steam turbine high pressure/intermediate pressure lower shell also has been installed, and preliminary alignments have begun. In addition, the heat recovery steam generator for the first combined-cycle unit has arrived on site.
GE gas turbine combined-cycle technology has been supplied to TEPCO for the following projects: - 14 Frame 109E gas turbine combined-cycle systems for Futtsu 1 and 2
- Eight 109FA combined-cycle systems for Yokohama 7 and 8
- Four 109FA systems for Chiba 2
- Four 109FA+e systems for Futtsu 3
- Three 109FA+e for Shinagawa 1
- Three 109H systems for Futtsu 4 (under construction)
