Siemens has received an order to build a new cogeneration plant in the Marzahn district of Berlin, a development that is expected to greatly assist the city’s climate neutrality objective.

The company will act as general contractor for the energy utility company Vattenfall Europe Wärme AG to erect this natural-gas fired combined-cycle power plant with district heat extraction. The centrepiece of the plant will be its gas turbine, which will be manufactured at Siemens’ gas turbine plant in Berlin’s Moabit district.

Scheduled to begin operation in 2020, this cogeneration facility will produce electric power while simultaneously supplying the east side of the German capital with district heating. The plant has an electrical generating capacity of 260 MW and a thermal capacity of 230 MW. The plant will contribute significantly to sustainably reducing Berlin’s CO2 emissions.

The order awarded to Siemens also comprises a long-term service agreement covering the gas turbine-generator set.

Willi Meixner, CEO of Siemens‘ Power & Gas Division said, “Environmentally friendly gas-fired cogeneration plants like Berlin-Marzahn can play an important role in pursuing the energy turnaround in Germany and urban centres around the globe.”

Siemens’ scope of supply includes the major components, i.e. the gas turbine, steam turbine and two electrical generators, all to be fabricated at Siemens manufacturing plants in Berlin, Görlitz and Erfurt, Germany. Siemens will likewise supply the heat recovery steam generator. The unit is to be erected in a multi-shaft configuration, and will achieve a fuel efficiency rating of approximately 90 per cent.

“Our district heating systems contribute significantly to achieving climate neutrality in Berlin. The new combined heat and power plant in Berlin’s Marzahn district will play a major role in these efforts, ensuring reliable, climate-friendly district heat for the coming decades and assuming the duty of base-load power plant for the district heat supply networks in the eastern part of the city,” notes Gunther Müller, Speaker of the Managing Board of Vattenfall Wärme AG in Berlin.

Vattenfall’s plans are part of the climate protection agreement concluded in the fall of 2009 between Vattenfall and the Berlin Senate by which Vattenfall undertakes to halve its CO2 emissions by the year 2020 based on the 1990 benchmark.
