Power Purchase Agreement for Renewable Energy from Biogas - Installation of Generating Capacity at Memphis Wastewater Treatment Plant

Shelby County, Tennessee

On March 7, 2012, TVA issued a final environmental assessment (EA) and finding of no significant impact (FONSI) for its actions to enter into a power purchase agreement with the City of Memphis. Under the terms of this agreement, TVA would purchase up to 2 megawatts (MW) of electricity generated from a biogas-fueled generation system at the M. C. Stiles Wastewater Treatment Plant in Shelby County, Tennessee. The electricity would be delivered through an on-site interconnection with the local power distributor, the Memphis Light, Gas and Water Division. The project involves installation of a reciprocating engine and generator within an existing building, as well as construction of a short underground biogas supply line from the existing central collection point and an on-site overhead transmission line.
