Arizona landfill gas project on line

The Glendale, Ariz., Energy Power Plant, a 2.8-megawatt biogas plant in the city of Glendale's municipal landfill, is now on line and serving customers of utility company APS. A dedication ceremony for the plant was held at the end of January, followed by "Lunch at the Landfill," which was open to the public. The project uses large combustion engines to turn a shaft connected to a generator, producing electricity from the landfill's methane emissions. APS has a power purchase agreement with Glendale Energy LLC. This is APS' first biogas project, but its renewable energy portfolio includes solar, wind, geothermal and biomass, together serving about 60,000 households.
