The Chilean water utility, Aguas Andinas is to install GE’s Jenbacher biogas engines as part of a wastewater treatment plant expansion and renewable energy project along the Mapocho River, near the capital city of Santiago.
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 Mapocho expansion project is being built adjacent to the utility’s existing El Trebal treatment facility and will enable Aguas Andinas to treat 100% of the Santiago region’s wastewater, up from the current 86%.
The expansion, including a modernization of the El Trebal facility, is expected to be completed between late 2011 and the first quarter of 2012.
Three of GE’s 2.7 MW J620 biogas engines will be installed to enable the plant to also begin producing up to 60% of its own power with renewable electricity.
The engines will be fuelled by methane-rich biogas created from the digestion of sewage sludge collected at the treatment plant.
By using the biogas as fuel in GE’s Jenbacher gas engines, less of the greenhouse gas is able to escape into the atmosphere.
Clarke Energy France, GE’s authorized distributor for gas engines in France, is supplying the biogas engines.
