GE’s HA turbine recognized for powering world’s most efficient power plants in both 50hz & 60hz segments
It’s official. There is another world record on the books for a combined-cycle power plant with an HA gas turbine at its heart!
Today we announced that the Chubu Electric Nishi-Nagoya power plant Block-1 – powered by GE’s 7HA gas turbine – has been recognized by GUINNESS WORLD RECORDS™ as the world’s Most efficient combined-cycle power plant, based on achieving 63.08 percent gross efficiency.
When Chubu Electric was looking to replace its 40-year-old Nishi-Nagoya facility, it selected a higher efficiency and more flexible large block gas turbine that could support multi-combined-cycle operation, provide low NOx emissions, and run on liquefied natural gas (LNG) fuel. What they ended up getting was a new definition of efficient power production.

Powering world records
When Chubu Electric was looking to replace its 40-year-old Nishi-Nagoya facility, they turned to GE’s 7HA gas turbine. What they got was world-record efficiency.
"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.
Racking-up Records
In June of 2016, GE Power and EDF were recognized by GUINNESS WORLD RECORDS for delivering the world’s most efficient combined-cycle plant in a 50hz market, powered by the 9HA turbine. The facility, in Bouchain, France, achieved an efficiency rate of 62.22 percent net efficiency and was also the world’s first combined-cycle plant equipped with GE’s HA turbine.
That means with this latest achievement, GE’s HA turbine now powers the world’s most efficient power plants in both the 50hz and 60hz energy markets. And there is much more to come.
GE supplied three more 7HA.01 gas turbines to Block-2 of the Nishi Nagoya facility, which is expected to achieve commercial operation soon. Japan along with the U.S. represent the largest 60Hz energy markets. GE already has two similar power plants fully commissioned in Texas that use 7HA technology, with many others coming online this year.
