Environmental Power and Xcel Energy Announce New Renewable Natural Gas (RNG(R)) Supply Agreement

“This effort further gives us the opportunity meet both our renewable energy and emissions reductions targets in Colorado,” said Tim Taylor, President and CEO of Public Service Co. of Colorado, an Xcel Energy company. “Microgy’s solution also gives us the added benefit of conserving traditional fossil fuels at one of our largest power plants.”

Microgy will use an anaerobic digestion process to break down animal waste from a local dairy farm and other organic waste products, such as food processing residuals, from along the Front Range of Colorado. The waste stream will be converted to methane gas using the anaerobic digesters. In turn, the methane will be used to help produce electricity at Fort St. Vrain, Xcel Energy’s largest natural gas generation facility in Colorado.

The renewable natural gas from this process is considered “carbon neutral,” and will count toward Xcel Energy’s RES mandate to produce 20 percent of its annual electricity from renewable resources, by 2020. In addition, the company also is working toward reducing carbon dioxide and other power plant emissions.
