The Reuter West combined heat and power plant is a coal-fired combined heat and power plant (HKW) in the Siemensstadt district of Berlin . It is located in the vicinity of HKW Reuter and was used as base load - power plant built. Both 300 MW - blocks were in 1987 and 1988/89 in operation. HKW Reuter West is the most powerful power plant of the Swedish energy group Vattenfall in Berlin. It can supply almost half a million households with district heating and one million households with electricity . The power plant is operated by the subsidiary Vattenfall Europe Wärme, which is part of the German subgroup .

Planning and construction
Initial plans for a new power plant in West Berlin included this in the area of the existing Oberhavel power plant . At the end of 1976 the Senate changed the plans and now planned the power plant on Oberjägerweg in Hakenfelde , right on the border with the GDR . In 1977 this planning was given up again and in 1978 the location next to the Reuter thermal power station was determined. The disadvantage of this location was the limited height due to the proximity to Tegel Airport . In the extreme case, a construction height of 122 m above the site would be possible. The original planning for the construction of the power plant envisaged a construction height for the boiler houses and cooling tower of more than 100 m. The cooling tower was now 100 m high and the chimney the maximum height of 122 m. An expert opinion from 1979 showed, however, that the reduced chimney height (compared to the original plan) can cause disruptions in the flue gas discharge. A satisfactory solution was only found with extensive model tests in the wind tunnel for various arrangements of the structures.
The construction plans for the boiler houses were adapted, whereby the floor space remained unchanged. The height of the boilers was reduced to 74 m, which was offset by a larger cross-section. As a result, the long-pipe blowers became longer at medium altitude. At these points they almost reached the inside walls of the boiler house and the wind instruments would no longer have been able to pass. Therefore, an extension of about 1.50 m wide was made in these areas.
The cooling tower is a natural draft cooling tower , which also had to be reduced in height compared to the original plan. As a result, the desired level of efficiency was not achieved.
A catalytic converter ( DeNOx ) to reduce nitrogen oxides is connected downstream of the boiler house . This is supported by two concrete columns, each with an elevator and a stairwell.
An electrostatic precipitator was installed downstream of the catalyst. This filters fly ash (also referred to as dust by law) from the flue gases .
Then there are the induced draft buildings , the flue gas desulphurisation system and the 122 m high chimney.
The grid connection takes place at the 380 kV maximum voltage level in the 50Hertz Transmission grid . The first mast of the 380 kV overhead line from the switchgear has been designed as a chimney-like 66 m high concrete mast (with steel trusses) for aesthetic reasons.

Planned district heating storage
From the beginning of 2014, a district heating storage facility will be built on the power plant site, which is to be put into operation at the beginning of 2016. At a height of 45 meters and a diameter of 44 meters, it should thermally hold 60,000 cubic meters of water with a storage capacity of 2500 MWh and thus enable the production and supply of heat to be decoupled. This should enable the combined heat and power plant (HKW) to operate independently of the heat demand at a high electricity price. On the other hand, it can also be switched off completely at certain times, for example if the HKW is not required due to low electricity requirements or high feed-in from regenerative producers . Thanks to the better utilization of the existing power plant fleet, annual carbon dioxide emissions should be reduced by around 100,000 tons.
Emissions
Coal-fired power plants are criticized for their pollutant emissions. Even after the installation of filter systems in the 1980s, which remove most of the sulfur from the exhaust gases, coal-fired power plants continue to emit relevant quantities of sulfur dioxide . In addition to sulfur dioxide, nitrogen oxides , which are harmful to the environment and health, as well as fine dusts that are harmful to health , the heavy metals and PAHs they contain, enter the environment. In Germany, the energy industry contributed 71% (6.571 tons) to total mercury emissions in 2010 .
The pollutant emissions of all large coal-fired power plants and industrial plants are published in the European Pollutant Emissions Register (via the German portal www.Thru.de).
Emissions below the reportable quantity threshold are listed in the table with "<" next to the limit value.
