Description: The use of digester gas driven fuel cells allows the Eastern Municipal Water District (EMWD) in Riverside County, CA to run some of its Moreno Valley and Perris Valley Regional Water Reclamation facilities during peak hours results in costs reduction of approximately $1 million per year. According to EMWD, the cells produce virtually no toxic emissions, cutting greenhouse gases by more than 10,600 tons annually—the equivalent of taking approximately 1,000 cars off the road for one year.
Goal: Power generation from renewable sources
Measurement: Reduced methane emissions and reduced grid or utility supplied energy use
