A waste management company and the state-owned utility, Electricité de France (EdF), signed an agreement to develop renewable energy from landfill methane. The "biogas project" operating during 1999 was centred near the town of Plessis Gassot, home to Frances largest municipal waste landfill. The waste management company, which operates the landfill, invested FRF 200 million in the infrastructure to capture the methane gas and burn it to produce 10 MW of electricity. EdF agreed to buy all the electricity production for a term of 12 years at a guaranteed price. A second facility at the same site is expected in 2004.
