Officials from French waste management and services company Véolia Propreté, energy services company Dalkia and distributed power services provider Clarke Energy have inaugurated the Electr’od landfill gas-powered cogeneration plant in Plessis-Gassot.
The 17.3 MW facility is the country’s most powerful landfill gas-fueled power plant and features 10 of General Electric Distributed Power’s ecomagination qualified Jenbacher gas engines to generate renewable electricity and heat for businesses and residents.
Clarke Energy is GE’s authorized distributor of Jenbacher gas engines in France.
The new cogeneration plant — which replaces a smaller, less efficient steam turbine-boiler system — uses the landfill’s methane-rich biogas to generate enough renewable electricity to power more than 41,000 French homes. The electricity is sold to Électricité Réseau Distribution France (ERDF) for use throughout France.
With the opening of the cogeneration project, Plessis-Gassot becomes the first town in France to have a district heating scheme fuelled by biogas. In addition to electricity, the cogeneration facility also produces 30,000 MWh/year of thermal energy. This energy is feeding a new heating and hot water network that serves homes and shared facilities in Plessis-Gassot, including the town hall, community center, church and municipal building. As a result, the electric heating bills for Plessis-Gassot residents who are connected to the grid supplied by Electr’od are expected to fall by 92 percent.
Installing GE’s gas engines increased the power output of the landfill gas plant by 5 MW while also improving its electrical efficiency from 22 percent up to 40 percent. 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 project also represents the first installation of GE’s Jenbacher Type 6 landfill gas engines in France.
Last month UK waste management company Biffa selected Clarke Energy to supply it with eight of GE’s Jenbacher landfill gas engines as part of a modernization of several landfill gas-to-energy plants across the UK.
