Nashville, Tennessee [RenewableEnergyAccess.com] With monthly sales surpassing 30,000 blocks of green power at 150 kilowatt-hours (kWh) each, Green Power Switch (GPS) consumers bought as many blocks of renewable energy as they wished. Each block added $4 to their monthly power bills.The Tennessee Valley Authority (TVA) and local public power companies, in cooperation with the environmental community, developed GPS as a way to bring green power — electricity generated by cleaner, renewable resources such as solar, wind, and methane gas — to Tennessee Valley consumers. Established on Earth Day 2000, the GPS program has grown steadily throughout its six-year history. Today, 8,457 residential customers and 453 businesses across the Tennessee Valley buy almost 55 million kWh of renewable energy each year (a 150-kWh block is equal to about 12 percent of a typical household’s monthly energy use). “The green power purchased each year by GPS subscribers has the environmental impact equivalent to removing about 15,200 cars from the highways for four months or recycling more than 26 million pounds of newspaper,” said Jerry Cargile, GPS senior product manager. The renewable energy sold through the GPS program is generated at Buffalo Mountain Wind Park in Tennessee, through cofiring of methane gas at TVA’s Allen Fossil Plant in Memphis, and at 16 solar sites throughout the Valley. TVA, one of the nation’s largest public power providers, is self-financed with revenues of $7.8 billion in 2005.
