GE's 7HA Gas Turbine Units Achieve Commercial Operation At Nishi-Nagoya Power Plant Block-1

  • Nishi-Nagoya power plant Block-1 will deliver 1,188 megawatts to the grid
  • Upon completion, the plant will be able to provide enough equivalent electricity to supply 400,000 average homes in Japan
  • GE’s HA fleet now operating in more than 5 countries with 30,000+ operating hours 

GE Power announced recently that commercial operation has been achieved for Chubu Electric Power Co., Inc.’s Nishi-Nagoya power plant Block-1 in Japan (Nishi-Nagoya) with GE’s gas turbines through Toshiba, the engineering, procurement and construction (EPC) company for the plant. Featuring GE’s highest efficiency 7HA gas turbine technology and Toshiba’s steam turbine technology, Nishi-Nagoya Block-1 will provide more than 1,188 megawatts (MW) of power to the grid with over 62 percent world-leading thermal efficiency, enough equivalent electricity to supply approximately 400,000 average homes in Japan. 

Today’s milestone follows several years of close collaboration between Chubu, Toshiba and GE to support highly-efficient thermal power generation in Japan. Chubu was initially looking to support the government’s initiative for cleaner, more efficient power generation by replacing its 40-year-old Nishi-Nagoya facility. Chubu selected a higher efficiency and more flexible large block gas turbine that could support multi-shaft (3on1) combined cycle operation, provide low NOx emissions, and run on LNG fuel. GE’s HA technology was chosen as the best proven technology for the project. 

GE is delivering a total of six 7HA.01 gas turbines for Nishi-Nagoya power plant. The HA is GE’s largest and most efficient gas turbine family; at the heart of Nishi-Nagoya, the 7HA will help increase thermal efficiency, reduce fuel consumption and CO2 emissions compared to other thermal power technologies. 

“GE’s HA technology underscores our company’s commitment to powering the world with more efficient energy solutions, and we are proud to achieve this milestone with Chubu and Toshiba,” said Bill Horie, country executive for GE Power in Japan. “The 7HA is a prime example of the important role GE can play in Asia’s energy future, and the HA’s proven operational experience in the field will provide more reliable, efficient and flexible power for years to come.” 

GE’s HA gas turbines are the fastest growing fleet of gas turbines in the world, achieving more than 30,000 combined operating hours of proven experience globally. The 7HA’s fuel flexibility accommodates a wide range of gas and liquid fuels, including high ethane (shale) gas and LNG. Additionally, the 7HA ramps up to full load in less than 30 minutes allowing for greater grid stability with renewable and alternative energy sources. 

GE has been committed to meeting the growing energy demand in Japan with industry-leading technologies for the past 40+ years. GE has delivered over 1,000 gas turbines in 15 countries in the Asia-Pacific region alone.
