Large Purchasers of Green Power

Washington Suburban Sanitary Commission

December 2006 - The Washington Suburban Sanitary Commission (WSSC), one of the 10 largest water and wastewater utilities in the nation, has committed to a 10-year wind power purchase to meet one-third of the agency's overall electricity use. The 70 million kWh annual purchase, equivalent to 30 MW of wind energy capacity, makes WSSC the number one local government user of renewable energy in the United States, according to the U.S. Environmental Protection Agency's Green Power Partnership.

WSSC is contracting with Constellation NewEnergy to purchase power from a new wind farm to be constructed in Somerset County, Pa. The arrangement involves paying a fixed price over 10 years, which WSSC estimates will save the agency $20 million dollars over the life of the contract while also providing long-term electricity price stability.
