Constellation is repowering its Criterion wind farm as part of a $350 million effort to increase the output and lifespan of the company’s renewable energy portfolio.

Over the course of this fleetwide project, Constellation said repowering efforts will enable 315 MW of its existing wind fleet to generate greater output at the same wind conditions. Constellation operates 27 wind projects that can produce about 1,400 MW of electricity.

Construction at Criterion Wind is underway with the installation of new, high-efficiency rotors, turbine blades and generators at the 28-unit site. The older turbine blades and equipment will be recycled. The power generated at the wind project will continue to be sold to Old Dominion Electric Cooperative (ODEC). The project is expected to be completed before year end.

Located in Oakland, Maryland, the 70 MW Criterion wind farm began operating in 2010.
