The Marzahn thermal power station (formerly Berlin-Lichtenberg thermal power station ) in the eastern part of Berlin is a thermal power station based on the principle of combined heat and power . It is located near the intersection of Rhinstrasse / Allee der Kosmonauten in the Marzahn-Hellersdorf district on the border with the Lichtenberg district .
The owner and operator is Vattenfall Europe Wärme AG , which is part of the Vattenfall Group .
The power plant between 1970 and 1990
The combined heat and power plant (HKW) was built in several stages from 1970 by the Berlin Energy Combine . This started the development of a 405 hectare area with industrial sites, which the power plant served to supply. In addition, the construction of the new residential areas around the village of Marzahn , which were heated with district heating from the power plant , began at this time . Since the area still belonged to the Lichtenberg district until the district reform in 2001, the power plant was named after him. This naming occasionally led to confusion with the in Lichtenberger district Rummelsburg located Klingenberg power plant . Even when the independent city district of Marzahn was founded in 1979 , to which this section of Rhinstrasse belonged, the name was retained. It was not until November 21, 2013 that the power plant was officially renamed from HKW Lichtenberg to HKW Marzahn , after the owner had applied for it in 2011.
In the first construction phase, an oil-fired boiler and a turbine set with an extraction condensing turbine and an electrical output of 32 MW were built. In 1975 the construction of a waste incineration plant (MVA) with a capacity of 80,000 tons of household waste per year began. It was the first in the GDR and remained the only one until its end. A steam line led from the MVA to the existing power plant. A second turbo set, also with 32 MW, was installed in the HKW during the same period. There are also other hot water generators , so that the total thermal output of the power plant after the completion of the expansion amounted to 1,255 MW and was the most powerful power plant in Berlin.
Since the GDR did not have efficient filter technology when the power station or the waste incineration plant was built, the practically unfiltered combustion gases were diverted through a 169 meter high chimney in order to distribute them over a wide area. A second chimney of the same height diverted the flue gases from six hot water generators.
Development after the fall of the Wall
Environmental groups and the population living in the area have criticized this situation, especially since the fall of the Wall . In particular, the suspicion, which has not been refuted, was expressed that larger quantities of dioxins are being released here. In 1990 this led to the decision to shut down the waste incineration plant.
With the merger of EBAG, which emerged from Energiekombinat Berlin, and Bewag (since 1998 Vattenfall Europe Berlin ) in 1993, the power plant was integrated into what is now the entire Berlin electricity and heating network. It forms part of the Power Plants East division .
In 2004, the turbine set 1 connected to the HKW was dismantled and sold to India , where it was used again in the local state of Chhattisgarh . After the second turbine set was also sold to India in 2011, only the gas-fired hot water generators of the 3rd and 4th construction stages are still in operation.
New building plans
In March 2012, work began on removing the northern chimney piece by piece. After the demolition of most of the more than 40-year-old power plant buildings, the Swedish company plans to build a highly efficient natural gas and steam turbine combined heat and power plant (CCGT) that will have an efficiency of around 90 percent. Only six of the nine large hot water generators remain standing and are integrated into the new power plant. The architects Gessert and Randecker and Glück Landschaftsplaner emerged as the winners of a Europe-wide competition for the new power plant . The drafts for the 500 million euro investment on the site will be revised again in 2013. To make room for the new building, the oil tanks and some outbuildings have also been removed. On the occasion of the project presentation, Vattenfall opened a visitor center in house Rhinstrasse 70 in November 2013. Residents and interested parties are invited to take a look at the power plant plans and can also find out about the construction progress there later. The construction project was to be put out to tender in 2014 with the aim of starting construction in 2015 and commissioning in 2018, but this schedule was not adhered to. In December 2015, Siemens was awarded the contract, according to Vattenfall, it should be built by 2020 [obsolete] . The costs for the new building and the new technology amount to 325 million euros . The company's head of Germany explained to representatives of the press: “With the construction of the thermal power station, we are fulfilling another point of our climate protection agreement with the Senate . We are right on schedule with halving our emissions compared to 1990. ”April 2017 was named as the start of construction.
