GE H-Class Gas Turbine Make New Guinnes World Record
The recognition is monumental for GE Power, whose Bouchain plant in France established the Guinness world record for the “most efficient combined cycle power plant” in April 2016 based on its verified efficiency of 62.22%. According to Guinness, “The efficiency figure signifies the amount of energy extracted from the total combustive energy contained in the fuel.”
Bouchain, a 605-MW unit that was also a POWER magazine Top Plant in 2017, comprises the first-of-its-kind GE 9HA.01 gas turbine (and it was the first combined cycle plant equipped with an HA turbine), a D650 steam turbine, and a W86 generator working in tandem. As POWERnoted, the plant can go from startup to combined cycle operation in less than 25 minutes and turned down to as low as 30% of its top generating capability while still meeting emission requirements.
“To support manufacturing by providing a stable and inexpensive power supply in Chubu, Japan’s central region, we have been making unremitting efforts to construct power generation facilities that achieve the world’s highest levels of output and efficiency,” said Satoru Katsuno, President & Director of Chubu Electric Power. “We believe that our constant quest for innovation led to this GUINESS WORLD RECORDS achievement.”
The Nishi-Nagoya Block-1 power plant is made up of GE’s three 7HA.01 gas turbines with Toshiba Energy Systems & Solutions (Toshiba ESS) Corporation’s steam turbine and generator technology, and overall plant system design and construction were achieved by Toshiba ESS. Providing more than 1,188 megawatts (MW) of power to the grid, that’s enough equivalent electricity to supply approximately 2.7 million average homes in Japan.
“We’re very proud to make history once again and to partner with Chubu and Toshiba to bring GE’s industry-leading HA turbine to Japan,” said Russell Stokes, President and Chief Executive Officer of GE Power.
