GE’s Rooftop Cogeneration System to Supply Tower of Deutsche Börse With Onsite Power

Posted on December 22, 2009

GE's Jenbacher cogeneration technology has been installed on the rooftop of the new office tower for Deutsche Börse Group in Eschborn, near Frankfurt, Germany, providing a secure and efficient supply of energy. The plant will be fueled by natural gas, a cleaner-burning alternative to other fossil fuels, to support Germany’s environmental initiatives. Surplus electricity will be sent to the regional grid to increase energy reliability for the Frankfurt area.

As part of its climate-change initiatives, the European Union (EU) has adopted several targets known collectively as its “20-20-20” goals: a 20 percent reduction in greenhouse gas emissions from 1990 levels; bringing renewable energy use up to 20 percent of the total energy mix; and an overall 20 percent reduction in energy use. To help achieve these targets, the EU is urging member states to expand the installation of combined heat and power (CHP) plants.

The new Deutsche Börse onsite power plant will enhance the energy security of operations that play a vital role in supporting Germany’s economy every day. The project developer, Groß & Partner and Lang & Cie, in late November celebrated the “roofing ceremony” for the 21-story building complex with the CHP plant. The plant’s two Jenbacher cogeneration units will provide 1.6 MW of electrical and thermal (heating and cooling) power to support the building’s operations. For the new rooftop CHP project, GE supplied project developer Wilhelm Theis GmbH with two JMS 412 Jenbacher cogeneration modules. .

In warmer months, hot water from the cooling circuit of the two cogeneration plants will serve as drive energy for two absorption chiller devices. During cold seasons, this thermal power will be utilized to meet the building’s heating requirements. The cogeneration plant is scheduled to begin commercial operation in the summer of 2010
