Bringing more Combined Heat and Power (CHP) to the Marzahn district in eastern Berlin, Siemens has won an order to build a gas-fired combined-cycle power plant with district extraction on behalf of Vattenfall Europe Wärme AG. Scheduled to start operation in 2020, the CHP will have an electrical generating capacity of 260MW and a thermal capacity of 230MW.
Under the order, Siemens will act as general contractor for Vattenfall to build and start up the CHP; the order also comprises a long-term service agreement covering the gas turbine-generator set.
The 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. Siemens will also 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%
Gunther Müller, Speaker of the Managing Board of Vattenfall Wärme AG in Berlin said the utility’s district heating systems help achieve 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," he said.
Plans for the Marzahn CHP are part of the 2009 climate protection agreement between Vattenfall and the Berlin Senate by which Vattenfall committed to half its carbon emissions by 2020, based on the 1990 benchmark.
Willi Meixner, CEO of Siemens' Power & Gas Division added that “environmentally friendly gas-fired cogeneration plants like Berlin-Marzahn can play an important role in pursuing the energy turnaround in Germany and urban centers around the globe."
