GE supplies gas engines for Chile landfill gas project expansion
Chile’s largest landfill is expanding its bioenergy capacity, adding six 1.4 MW GE Jenbacher engines to the existing seven.
The 8.4 MW expansion at the Loma Los Colorados Landfill will bring the total power generation to 18 MW, enough for about 75,000 homes. The expansion should be ready for operation between 2012 and 2014, according to GE.
“We are very excited to build on the success we have had with our Loma Los Colorados landfill gas-to-energy project, which is serving as an important renewable energy model for the region as Chile looks to diversify its energy mix,” said Sergio Durandeau, general manager of KDM Energía, which owns the landfill and the power plant.
KDM Energía selected GE’s Jenbacher gas engine technology because of the J420 engine’s performance on other landfill gas-to-energy projects worldwide and the local support provided with Generadora Transandina SA, GTSA, GE’s authorized distributor and service provider for Jenbacher gas engines in Chile. GE also provided a master engine control system to help achieve maximum availability and efficiency from the generating equipment.
In addition to the Loma Los Colorados Landfill project, GE will supply three of its 2.7 MW ecomagination-approved J620 Jenbacher biogas engines as part of Chilean water utility Aguas Andinas’ wastewater treatment plant expansion and renewable energy project near the capital city of Santiago. GE expects to commission the engines during the second half of 2012. The project is part of Chile’s efforts to clean up the city’s municipal water supply and protect the region from the environmental impacts of continued population growth. The project will allow production of up to 60 percent of the water utility’s own power with renewable electricity. The engines will be fueled by methane-rich biogas created by the digestion of sewage sludge collected at the treatment plant.
