KNOXVILLE, Tenn. (AP) — The Tennessee Valley Authority is one of the top 10 utilities for green power sales.

The U.S. Department of Energy’s National Renewable Energy Laboratory ranked TVA at number nine nationally for 2013.

In addition, the city of Oak Ridge was designated the U.S. Environmental Protection Agency’s first Green Power Community in the Southeast. That’s based in part on participation in TVA’s Green Power Switch program.

According to the utility, Green Power Switch gives consumers and businesses the opportunity to buy blocks of electricity generated by renewable resources like solar and wind.

Oak Ridge increased participation in Green Power Switch from 500 customers to more than 800 during a two-month campaign. The enrollment represents more than 5 percent of Oak Ridge’s customers, the highest rate of any community in the program.
