Under the contract, Siemens will deliver two SGT5-8000H gas turbines, each with a capacity of 400MW as well as associated auxiliary systems for the combined cycle power plant.
Fuji Electric is responsible for erecting the plant on a turnkey basis for KOBELCO.
Located inland approximately 50km west from the shore of the Pacific Ocean, the power plant will feature an air-cooled condenser and is expected to commence commercial operation at the end of 2019.
The power plant, which will have an installed capacity of more than 1.2GW, is scheduled to receive environmental impact assessment approval in mid-2016.
Siemens Division Power and Gas CEO Roland Fischer said: "We are pleased that we have now been able to enter onto the Japanese market with our innovative and yet extensively proven gas turbine after selling them in South Korea, Malaysia and the Philippines.
With an efficiency level of more than 61%, the facility is expected to be the most powerful and most efficient gas-fired power plant in the country.
"Our H-Class turbine series, with its record-setting levels of performance and efficiency, is excellently suited for countries which need to meet their power demands quickly and with the latest technology and using machines with proven reliability," added Fischer.
