(LAKE MARY, FL   01/18/11)   Mitsubishi Power Systems Americas, Inc. (MPSA) has received an order from Virginia Electric and Power Company (VEPCO) to supply three M501GAC gas turbines and one steam turbine to be installed at the company’s Warren County power plant near Front Royal, Virginia. The new gas turbine combined cycle (GTCC) power islands will have more than 1,300 megawatts (MW) of generation capacity.

The gas and steam turbines have been ordered through MPSA as the business base for Mitsubishi Heavy Industries’ (MHI) power system operations in the U.S. Current plans call for the plant to be operational in late 2014 or early 2015. Under a separate long-term service agreement, MPSA will provide comprehensive turbine maintenance, repair and outage services as well as replacement parts supply for the GTCC power blocks.

The M501GAC is one of the most efficient and large-capacity – 60 Hz (hertz) – gas turbines in the world. To date, MHI has received orders for over 65 units of M501G worldwide, including more than 30 units in the North America.

With GTCCs, gas and steam turbines are used in combination to generate electricity in two stages, utilizing high-temperature exhaust gas from the gas turbine to produce the steam to drive the steam turbine. This configuration enables GTCC power plants to achieve a higher thermal efficiency, which in turn reduces fuel consumption and lower emissions.

VEPCO, a subsidiary of Dominion, is a public utility that provides services in electricity generation, transmission and distribution. Dominion is one of the North Americas’ largest producers and transporters of energy with a portfolio of more than 27,600 megawatts of generation, 12,000 miles of natural gas transmission, gathering and storage pipeline and 6,000 miles of electric transmission lines in the area of Virginia and North Carolina.
