Plan for Development of Nishi-Nagoya Thermal Power Station Group No. 7
September 14, 2010
Chubu Electric Power Co.,Inc.
Chubu Electric Power Co., Inc. has today decided on a plan for the refurbishment of the Nishi-Nagoya Thermal Power Station, which will see the decommissioning of Units No. 1-4 and the construction at the station of an LNG-fired combined cycle facility with the world's highest level of efficiency. The Tobishima-mura and Aichi Prefecture authorities have been notified of the plan.
Under the new plan, the existing Units No. 1-4 (total output: 1,190 MW) will be decommissioned and dismantled, the previously decommissioned Units No. 5 and 6 will be dismantled, and a new 2,200 MW-class facility (Group No. 7) will be constructed, looking towards the commencement of operation in FY2019.
This replacement of a station that has been in operation for approximately 40 years with a high-efficiency facility can be expected to reduce CO2 emissions and the amount of fuel used by increasing the overall thermal efficiency of Chubu Electric's thermal power stations.
Chubu Electric looks forward to working with the local population and institutions in this area as we develop these plans.
In order to enable us to provide our customers with a safe and stable supply of high-quality, low-cost energy into the future, in addition to helping to protect the global environment, Chubu Electric is proceeding with the planned development of facilities, promoting the use of nuclear power and introducing high-efficiency thermal power stations.

- How Combined Cycle Generation Works
Fuel (natural gas) is combusted, and the energy from the combusted gas rotates a gas turbine. Heat from the high-temperature exhaust gas discharged from the gas turbine is effectively recovered by a waste heat recovery boiler. This heat is used to generate high-temperature, high-pressure steam, which rotates a steam turbine.
The combined force generated by the gas and steam turbine is used to rotate a generator. This efficient mechanism of power generation is termed combined cycle generation.
