Bavarian Utility Installs GE's J920 FleXtra Gas Engine Cogeneration System to Support Germany's Energy Transition Plan
ROSENHEIM, Germany--(BUSINESS WIRE)-- With Germany's "Energiewende" energy transition plan emphasizing greater industrial energy efficiency, Bavarian Minister of State for Environment & Health Dr. Marcel Huber and other government and business leaders today celebrated the official startup of the Stadtwerke Rosenheim municipal cogeneration plant expansion in the city of Rosenheim.

"The energy transition plan 'Energiewende' can be achieved only if there is a cooperative effort, including contributions by municipal providers. Investments in innovative, modern power plants create an important foundation for the successful execution of our energy transition plan," Huber said.
The project's centerpiece is GE's (NYS: GE) largest Jenbacher gas engine, the 9.5-megawatt (MW) ecomagination qualified J920 FleXtra. GE's new, flexible power solution combines extra innovation, power and efficiency to help customers address their local energy security priorities while achieving improved environmental performance. GE expects the J920 FleXtra will be available in 60-Hz regions in 2014.
Stadtwerke Rosenheim's integrated combined heat and power (CHP) facility also features an existing waste incineration plant and four previously installed Jenbacher engines—three 3.35-MW J620 engines and a 4.4-MW two-stage turbocharged J624 unit. The upgraded cogeneration facility (36.1 MWel and 43.8 MWth) now meets about 40 percent of the electricity needs and 20 percent of the heating requirements of Rosenheim, which has more than 61,000 inhabitants.

Germany plans to shut down its remaining nuclear power plants by 2022. To replace the low-carbon baseload electricity from the nuclear plants, the government's energy transition plan calls for increasing the use of natural gas and renewable energy as well as more energy efficiency technologies.
Installing the J920 FleXtra helps Stadtwerke Rosenheim more closely align its cogeneration plant with Germany's goal to increase CHP power generation to 25 percent of the country's total power supply by 2020. The natural gas-fired J920 CHP system provides electricity and thermal power (hot water) for local residents and industrial customers with a lower carbon footprint compared to conventional power plants, supporting Germany's effort to reduce greenhouse gas emissions by 40 percent by 2020.
Also, the J920 FleXtra engine's extremely short start-up time increases Stadtwerke Rosenheim's operational flexibility to overcome the challenges of intermittency associated with adding more renewable energy supplies.
"Our new cogeneration plant featuring GE technology will enable us to deliver a reliable, efficient and more flexible supply of power and heat to our business and residential customers," said Dr. Götz Brühl, CEO of Stadtwerke Rosenheim.
GE's J920 FleXtra commands the highest electrical efficiency in the 10-MW class and is designed to achieve an industry-leading electrical efficiency of 48.7 percent and about 90 percent efficiency in cogeneration mode.
"Our flexible J920 technology offers both high efficiency and reliability levels, which makes it the ideal large gas engine distributed power solution for industrial and grid stabilization applications while also minimizing the customer's carbon footprint," said Karl Wetzlmayer, general manager of gas engines for power generation—GE Power & Water.
