GE commissions 7HA.01 gas turbines at Nishi-Nagoya power plant in Japan

EBR Staff Writer Published 03 October 2017

GE Power has commissioned its 7HA.01 gas turbines at Chubu Electric Power’s Nishi-Nagoya power plant in Japan.

The company has installed six 7HA.01 gas turbines at the Nishi-Nagoya Block-1 as part of a contract with engineering procurement and construction (EPC) company Toshiba.

Featuring GE’s 7HA gas turbine technology and Toshiba’s steam turbine technology, the facility holds a capacity to generate around 1,188MW of electricity, which can be supplied to about 400,000 homes on an average in the region.

The 7HA turbine offers flexibility to accommodate a range of gas and liquid fuels, including high ethane (shale) gas and LNG. In addition, it can achieve full load within 30 minutes, providing grid stability with renewable and alternative energy sources.

GE’s 7HA is available in two models, 7HA.01 at 289MW and 7HA.02 at 372MW. It features 14-stage advanced compressor with 3D aerodynamic foils as well as three stages of variable stator vanes and field-replaceable blades.

The turbine comprises simplified dual-fuel system that uses less water to avoid recirculation.

GE Power Japan country executive Bill Horie said: “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.

“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.”
