SMITHTON, Pennsylvania – Tenaska Pennsylvania Partners, LLC today celebrated the start of construction for the Tenaska Westmoreland Generating Station, a 925-megawatt (MW) natural gas-fueled power plant near Smithton in Westmoreland County.

More than 75 elected officials, community leaders and company executives gathered at the site for the ceremonial groundbreaking.

“Natural gas production is an important industry in Pennsylvania and is one that not only creates direct employment but also stimulates the economy and fosters additional jobs through its support of related, downstream businesses,” said Dennis Davin, Pennsylvania Secretary of Community and Economic Development, who gave the keynote address. “On behalf of the Commonwealth of Pennsylvania and the Department of Community and Economic Development, it’s an honor to welcome Tenaska to Westmoreland County and to break ground on a project that is sure to be a significant contributor to the vitality of the region and beyond.”

Construction of Tenaska Westmoreland is expected to be completed in late 2018. The plant will be able to provide enough power for approximately 925,000 homes in the PJM Interconnection market, which coordinates the delivery of reliable power in all or parts of 13 eastern states, including Pennsylvania, and the District of Columbia.

“Tenaska has a nearly 30-year reputation for strong power projects that fit the needs of market,” said Vice Chairman and CEO Jerry Crouse. “We are pleased to continue that tradition with Tenaska Westmoreland.”

Tenaska Westmoreland is the 18th project that Tenaska has developed, financed and advanced to construction. Since its founding in 1987, the company has successfully developed approximately 10,000 MW of natural gas-fueled and renewable power projects and currently has approximately 2,500 MW in additional projects in pre-financing development.

Tenaska Pennsylvania Partners, LLC, comprised of affiliates of Tenaska and Diamond Generating Corporation, a subsidiary of Tokyo-based Mitsubishi Corporation, owns the Tenaska Westmoreland project.

“Diamond Generating Corporation is pleased to be a part of this highly efficient, combined-cycle project in Pennsylvania, continuing our long-term relationship with Tenaska” said CEO Satoshi Hamada. “The Tenaska Westmoreland Generating Station demonstrates our commitment to provide clean, flexible and reliable energy for local communities in competitive markets.”
