GE gas-fired engines to power London 2012 Olympic Games
Three of GE's 3.3-MW Jenbacher J620 cogeneration units are powering the energy centers and generating electricity equivalent to the amount used by 24,000 average U.K. homes
London, July 25, 2012 — Two new energy centers in London's Stratford City and Kings Yard areas are ready to supply 10 MW of efficient power, heating and cooling for the London 2012 Olympic Games and Paralympic Games as well as East London's businesses and residential areas after the Games conclude.
The London Olympic Delivery Authority built the facilities to help reach its target of a 20 percent reduction in carbon emissions while meeting the city's power needs that are expected to surge as more than 15,000 athletes and millions of spectators arrive for the Games.
The energy centers are designed to operate in combined cooling, heat and power — or trigeneration — mode to reduce carbon dioxide emissions. Chilled water is generated by absorption chillers using the high-temperature heat available from the exhaust of the unit.
Combined heat and power (CHP) technologies are more efficient than using separate electrical and thermal power systems and thus helps to reduce emissions from power generation. By using this technology, about 13,000 tons of carbon savings can be achieved.
The first energy center, featuring two of GE's J620 natural gas cogeneration modules, is located in the Stratford City development area and will support various Olympic Park activities as well as commercial redevelopment in East London.
The second energy center, located at Kings Yard on the western end of Olympic Park, features one J620 cogeneration system that will generate thermal power for the aquatics center's swimming pools and other venues via the Olympic Park's district heating network.
The Kings Yard facility also will generate electrical and thermal power for other venues, homes and buildings in the area. Both energy centers will include boilers that use natural gas as feedstock to generate additional heat to meet peak demands. The Kings Yard facility also includes a 3-MW boiler that will be fueled with wood chip biomass to generate additional heat during the winter.
In all, GE has supplied more than 800 Jenbacher engines for on-site power projects in the United Kingdom, representing about 8 percent of GE's globally installed Jenbacher fleet. Combined, these units generate electricity equivalent to the amount used by about 1.8 million E.U. homes.
