New Biogas Energy Plant Online
Project marks first installation of GE Jenbacher J620 landfill gas engines in France
GE has installed 10 landfill Jenbacher gas engines at the newly inaugurated Electr’od landfill gas-powered cogeneration plant in Plessis-Gassot, France
GE said it has increased the plant power output by 5 MW while also improving its electrical efficiency from 22 to 40%. The new plant consists of 10 Jenbacher units: four 2.7 MW J620 gas engines, five containerized 1.1 MW J416s and one containerized 1 MW J320.
The plant replaces a smaller, less efficient steam turbine-boiler system and uses the landfill’s methane-rich biogas to generate enough renewable electricity to power more than 41 000 French homes (excluding heating). The electricity is sold to Électricité Réseau Distribution France (ERDF) for use throughout France.
GE said the 17.3 MW facility has made Plessis-Gassot the first town in France to have a district heating scheme fueled by biogas energy. The cogeneration facility also produces 30 000 MWh/yr of thermal energy, feeding a new heating and hot water network that serves homes and shared facilities in Plessis-Gassot. As a result, the electric heating bills for residents supplied by Electr’od are expected to fall by 92%, GE said.
The facility was developed by French waste management and services company Véolia Propreté; GRS Valtech; energy services company Dalkia France, a subsidiary of Veolia and French utility EDF; and Clarke Energy, the authorized distributor and service provider for GE’s Jenbacher gas engines in 16 countries.
