Casper, Wyoming [RenewableEnergyAccess.com] The United States Department of Energy (DOE) has made a large renewable energy purchase from Rocky Mountain Power for its Rocky Mountain Oilfield Testing Center at the Teapot Dome Naval Petroleum Reserve #3.The testing center is buying 1,105 blocks of 100 kilowatt-hour (kWh) Blue Sky wind energy each month. According to Doug Tunison, technical services manager at the Rocky Mountain Oilfield Testing Center, the purchase is a good first step toward developing its own clean energy resources. “We’re developing and demonstrating best practices for the oil and gas industries, including integrating fossil-fuel and renewable technologies,” Tunison said. “Teapot Dome may have a lot of potential for wind and geothermal development, and we plan to install wind turbines ourselves. But that is going to take some time, so buying Blue Sky is a good interim step.” The Oilfield Testing Center is making its purchase through Rocky Mountain Power’s Blue Sky Quantity Savings program, which allows large wind energy purchases at a reduced cost (one 100-kWh increment of Blue Sky costs $1.95 per month in addition to a customer’s regular bill). Over the course of a year, the testing center’s Blue Sky purchase will reduce carbon dioxide emissions by 1,326 tons, which has the same environmental benefit of planting 521 acres of trees or not driving more than 2.8 million miles. Rocky Mountain Power’s Blue Sky comes from western wind farms, including two in Wyoming: the Foote Creek IV Wind Energy Project near Arlington and Pleasant Valley Wind Energy near Evanston, which is located on ranch land used for cattle grazing.
