Penn Doubles Its Wind Power Purchase to 10 Percent

The University of Pennsylvania (Penn) announced on April 21st that it has doubled its purchase of wind-generated power. Penn will now buy 40 million kilowatt-hours of wind power annually from Community Energy Inc.—the largest retail purchase of green power in the nation. The university's new 10-year commitment will lead to the construction of a new wind power facility in Pennsylvania. See the Penn press release.

Green power sales are also supporting wind power in New York State, where Green Mountain Energy Company (GMEC) has bought all the environmental attributes associated with wind power production from the Madison Windpower facility near Hamilton. The wind power credits will be used to meet the demand for people buying green power through the Niagara Mohawk Renewable Energy Program. See the GMEC press release.

The credits purchased by GMEC are often referred to as "green tags"—also known as "tradable renewable credits"—and are a growing market for renewable energy. As one sign of that growth, the Center for Resource Solutions announced in early April that its Green-e Program has certified the first-ever wholesale broker for green tags. Evolution Markets LLC hopes to make green power transactions easier by helping to build a wholesale market for green tags. See the Green-e press release.
