GE Supplys Jenbacher Gas Engines for Landfill Plant in La Reunion

GE Energy is providing two of its Jenbacher gas engines for a new 2-megawatt (MW) landfill gas-to-energy plant on the small French island of La Reunion in the Indian Ocean, 680 kilometers east of Madagascar.

GE is supplying two of its JMS 320 GS/L.L gas engines for the plant being installed near the town of Saint-Pierre. The two Jenbacher units combined will generate more than 2 MW in electrical power, which will then be sold to the local grid. Meanwhile, the engines’ combined 1,172 kilowatts (kW) in thermal power (without the use of exhaust gas heat) will create hot water for the landfill’s leachate treatment system, which utilizes a thermal evaporation process in vacuum conditions. Under challenging tropical climatic conditions, the engines will provide an electrical efficiency of about 40.1%.

The landfill gas project is part of La Réunion’s efforts to become completely independent from energy imports by 2025. To reach this goal, the island needs to add an estimated 400 MW in generating capacity from various sources. France’s “obligation d’achat” feed-in tariff system, which provides incentives for installation of additional renewable energy capacity, helped make the La Réunion landfill gas project more economically feasible for the project’s developer.

“This project is GE’s first landfill gas plant to be installed in any of France’s overseas regions, and we are looking forward to supporting La Réunion’s efforts to create a more sustainable, secure and autonomous energy infrastructure,” said Prady Iyyanki, CEO of GE Energy’s Jenbacher gas engine business.

GE’s authorized Jenbacher gas engine distributor Clarke Energy France is installing the units on behalf of project developer and investor GRS Valtech, a subsidiary of VEOLIA Environmental Services. The units are scheduled to enter commercial operation in November 2008.
