MHI to Supply Two M501GAC Gas Turbines to Old Dominion Electric Cooperative of the United States

The order for the two gas turbines will be placed with Mitsubishi Power Systems Americas, Inc. (MPSA), MHI's wholly owned subsidiary for power systems business in the U.S. ODEC's proposed GTCC plant will be built five miles west of the Town of Rising Sun, Maryland, on a site adjacent to two simple-cycle peaking generation units owned by ODEC.

The GTCC power generation system for ODEC will consist of two M501GAC gas turbines, a steam turbine, a heat recovery steam generator (HRSG) and a generator. The gas turbines will be manufactured at MPSA's Savannah Machinery Works in Savannah, Georgia. The generators will be supplied by Mitsubishi Electric Corporation. After the plant begins operating, under the LTSA arrangement MPSA will provide the Wildcat Point Generation Facility with comprehensive turbine maintenance and management services, replacement parts supply, and dedicated remote turbine monitoring.

The M501GAC gas turbine is one of the most efficient, large-capacity gas turbines in the world. To date MHI has received orders for more than 80 units of its G series worldwide, including more than 40 in North America, and 13 of those units are the M501GAC. The current order reflects this excellent track record, as well as the M501GAC gas turbine's reputation for superior performance.

ODEC is a not-for-profit, member-owned power generation and transmission cooperative federation headquartered in Glen Allen, Virginia. It supplies electricity to 11 member electric distribution cooperatives in Maryland, Virginia and Delaware.

Gas turbine combined cycle power plants generate electricity in two stages through the combined use of gas and steam turbines. By using high-temperature exhaust from the gas turbine to produce the steam that drives the steam turbine, combined cycle power plants achieve higher thermal efficiency, lower fuel consumption and lower emissions.

MHI has already delivered many GTCC power generation systems in Japan and around the world, and it enjoys a solid reputation for its technological expertise and delivery track record. With the additional momentum provided by this latest order, the company looks to further strengthen its marketing activities for GTCC power generation systems in the future.
