Clipper receives wind energy order from Constellation Energy

The Criterion Project, slated for immediate construction, is expected to be online by year-end 2010. "As Maryland’s first wind energy facility, the Criterion Project will be a source of both new green jobs and clean energy" said John Lamb, CEO of Clipper Windpower Development Co., Inc. "Equipped with American-made 2.5 MW Liberty wind turbines, the wind farm project will be state-of-the-art and a source of pride for the State and Constellation Energy."

Clipper employees based in Garrett County will provide operation and maintenance services for the Project under a long-term agreement, and 24/7 operation oversight will be provided through Clipper’s Remote Maintenance and Diagnostic Center located at its Cedar Rapids, Iowa manufacturing facility.

The Criterion site is located in Garrett County, Maryland, to the east of the county seat of Oakland. Initiated in 2001, the proposed project has undergone studies and extensive review by the state, local agencies and the local public. Criterion supports Maryland’s Renewable Portfolio Standard (RPS) which encourages new wind energy projects within the State of Maryland.

The Project’s wind turbines will be built at Clipper’s 330,000 square foot manufacturing facility in Cedar Rapids, Iowa. Earlier this year, Clipper announced a 49.5% investment in Clipper Windpower Plc by United Technologies Corporation, a global provider of high technology products and services to the building systems and aerospace industries.
