EDF Renewable Energy closed on the membership interest purchase agreement to acquire the Heartland Biogas Project with Heartland Renewable Energy. The 20MW equivalent anaerobic digester and renewable natural gas (RNG) facility has commenced construction activities with biogas deliveries to begin by the end of first quarter 2014. The project, located near LaSalle, Colorado, uses a complete mix anaerobic digester system to produce up to 4,700 MMBtu of biogas daily. The anaerobic digestion system converts organic feedstock and dairy cow manure into raw biogas. The raw biogas is then processed into pipeline quality RNG. After being conditioned to pipeline grade, the RNG will be supplied to Sacramento Municipal Utility District (SMUD) through a 20-year gas purchase agreement (GPA).
