Mitsubishi Heavy Industries, Ltd. (MHI) has shipped the first commercial-use unit of the “M501J” – a gas turbine that has achieved the world’s highest efficiency and power generation capacity in a system of this type – from its Takasago Machinery Works in Takasago, Hyogo, to the Himeji No.2 Power Station of Kansai Electric Power Co., Inc. (Kansai EP) in Himeji, in the same prefecture.
The first unit and five additional M501J gas turbines to be delivered later will become the core components of the high-efficiency, natural gas-fired gas turbine combined cycle (GTCC) power generation plants at the Himeji No.2 Power Station, each unit producing 486.5 MW for a collective total of 2919 MW.
The Himeji No.2 Power Station is one of Kansai EP’s largest thermal power stations. Since operation of the first power generation unit began in 1963, it has consistently played a key role as Kansai EP’s major power supply source. Currently the power station is undergoing replacement of its aged power generation facilities, and installation of the M501J gas turbines is part of this initiative.
The six units are slated to go on-stream progressively between October 2013 and October 2015. MHI will undertake installation work together with Kansai EP, aiming toward achievement of the world’s most efficient GTCC power generation facility when completed.
