Mitsubishi Hitachi Power Systems Americas Inc. (MHPSA) said May 15 that it has received an order from Virginia Electric and Power (VEPCO) for the supply of three M501J gas turbines to be installed at VEPCO’s Greensville County Power Station.
VEPCO is a regulated subsidiary of Dominion Resources (NYSE: D) and has yet to seek approval of this project at the Virginia State Corporation Commission.
The three gas turbines will be manufactured and assembled at MHPSA’s Savannah Machinery Works at Savannah, Georgia, to support a project completion date of year end 2018. The new gas turbine combined cycle (GTCC) power plant will combine the output of the three, highly efficient M501J gas turbines with a steam turbine resulting in the largest new construction GTCC block in North America. The gas-fired plant will produce approximately 1,600 MW.
This order is the third for MHPSA’s advanced design gas turbines placed by VEPCO over the last five years. The Warren County and Brunswick County power stations each utilize three M501GAC gas turbines combined with a steam turbine. Warren County has already achieved commercial operation and Brunswick County will follow in 2016. All three sites are covered by an MHPSA long-term maintenance agreement to provide parts, repairs and maintenance services plus remote monitoring of vital operating data.
The M501J is the most efficient large frame gas turbine in commercial operation with 17 turbines accumulating over 126,000 operating hours for six different owners, Mitsubishi said. Worldwide, there are contracts for 36 Mitsubishi Hitachi Power Systems J class gas turbines, including six in North America. The M501J resulted from the pioneering efforts of Mitsubishi Hitachi Power Systems in development of market leading, highly efficient gas turbine technology accumulated from 20 years of analysis, test and operation of 60 Hz gas turbines over 250 MW.
