Mitsubishi to supply two gas turbines for Tenaska’s Westmoreland project

Mitsubishi Hitachi Power Systems Americas Inc. (MHPSA) said April 19 that it has been awarded a contract by Tenaska to provide two M501J gas turbines, each rated at 327 MW, and generators for the Tenaska Westmoreland Generating Station, located in Westmoreland County, Pennsylvania.

The contract award for this 2-on-1, 925-MW project also includes a Long-Term Service Agreement for MHPSA. A Tenaska affiliate, Tenaska Pennsylvania Partners LLC, will build, own, and operate the facility.

“We are pleased to be working with Mitsubishi Hitachi Power Systems Americas for the power generation technology and long-term service of the Tenaska Westmoreland facility,” said Nick Borman, Tenaska senior vice president of engineering and construction. “The industry-leading efficiency and reliability and five year commercial operating track record of the J-series, combined with Tenaska’s expertise in power generation facilities, will help ensure Tenaska Westmoreland is a safe, efficient and reliable power plant.”

“The J-series turbine provides a unique combination of proven operating experience and world class output, efficiency, and reliability. In commercial operation since 2011, our best-in-class turbine provides a combined cycle efficiency approaching 62% and proven reliability in excess of 99%,” said Paul Browning, president and CEO of MHPSA. “Being chosen by Tenaska, an organization with a 30 year history of successfully developing power projects, clearly demonstrates that experienced project developers have embraced our technology. No other gas turbine in this 300 MW+ size range has even a single hour of commercial operating experience.”

A total of 43 J-Series gas turbines have been ordered. Nineteen of these units are in commercial operation and collectively have achieved over 220,000 actual operating hours. Ten of the 43 J-Series units on order will be installed in North America. MHPSA’s first U.S. manufactured M501J was delivered in March from the company’s manufacturing facility in Savannah, Georgia, to the Grand River Dam Authority for installation at the Energy Center in Chouteau, Okla.

Tenaska said April 19 that it has closed on roughly $780m of commercial financing for the 925-MW Tenaska Westmoreland Generating Station. Construction began earlier this year, with commercial operation targeted for 2018. Black & Veatch is the engineering, procurement and construction (EPC) contractor for the project.

MHPSA is a wholly-owned subsidiary of Mitsubishi Hitachi Power Systems Ltd. Headquartered in Lake Mary, Florida, MHPSA employs over 2,000 in the Americas and has the world’s most modern heavy duty gas turbine and steam turbine factory, located in Savannah, Ga.
