United Kingdom : GE s Gas Engine CHP Systems Set to Power London 2012 Olympic Games
Power Industry News (press release)
Two new energy centers in London s Stratford City and Kings Yard areas are ready to supply 10 megawatts (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. Three of GE s (NYSE: GE) 3.3-MW ecomagination-qualified Jenbacher J620 cogeneration units are powering the energy centers and generating electricity equivalent to the amount used by 24,000 average U.K. homes.
The energy center initiative is a cornerstone of London 2012 s plan to increase the use of alternative energy, water conservation and recycling to minimize the environmental impact of the Games. 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 (CO2) 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 CO2 savings can be achieved. This amount of greenhouse gas emission savings is equivalent to the annual CO2 emissions emitted by about 6,500 European Union (EU) passenger cars.
Our energy centers powered by GE s gas engines are not only crucial to the success of the London 2012 Olympic Games but also for the goal of establishing a more sustainable business and residential environment throughout the city long after the Games have ended, said Simon Wright, director of infrastructure and utilities for the Olympic Delivery Authority. The Stratford City and Kings Yard energy centers are expected to support future commercial development in East London for at least 40 years.
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.
