Unlocking The Power Of Geothermal Energy (Diesel & Gas Turbine Worldwide)
Renewable, geothermal energy production equipment tested to the limit
An English manufacturer of a range of power generation equipment including turbogenerators and switchgear is helping unlock reserves of energy at a remote South American geothermal facility.
Brush, based in Loughborough, England is supplying two specially-modified, 27.6 MW, four-pole, 1500 r/min generators to the site with a rated voltage of 9500 V and a power output of 32,471 kVA. The generators are powered by 15 MW turbines and have been designed to withstand the challenges presented by extracting geothermal energy in high altitude conditions.
Located on an Andean plateau 4500 m above sea level in the north of Chile at Cerro Pabellón, the first geothermal plant in South America is under construction following a US$320 million investment, financed through resources provided by Enel Green Power. Cerro Pabellón is thought to be the first binary geothermal plant in the world to be built at such a high altitude. It is due to be completed in 2017.
Regions of geothermal activity are rich in toxic natural gases. Brush said its generators are suitable for these corrosive environments and adapted to be extra protected against hydrogen sulphide (H2S) and sulphur dioxides (SO2), which pose a substantial operational hazard.
