Datteln 4 - Kraftwerk Datteln

Who needs the energy from Datteln?
Energy production is a traditional part of Datteln. Since 1964 the hard coal-fi red power
plant in Datteln has supplied electricity to the Bahn, as well as district heating to the
urban area, thus being an important economic factor for the city and region. As part of
the pan-European supply grid, Datteln 4 contributes to making sure that energy is always
there when you need it.
Traditional location with a future
The power plant units Datteln 1 – 3 as well as the
power plant Shamrock in Herne will be at the end
of their technical and economic lifetimes in the
next few years. They need to be replaced with new,
effi cient and more environmentally friendly facilities.
E.ON is investing more than one billion Euros
in the construction of the hard coal fi red power
plant Datteln 4. At the same time the operation of
the Datteln 4 power plant not only secures the jobs
of the Datteln 4 employees, but many other jobs
throughout the region as well.
Electricity for the train
A fi fth of the electricity used by Deutsche Bahn
to run its trains comes from Datteln. In the future,
this fi gure will rise to 25 %. Aside from district
heating, the power plant units Datteln 1 through 3
produce only 16.7 Hertz traction current.
Datteln 4 generates the 50 Hertz electricity
needed by the public supply grid. For this reason,
it needs to be transformed into the 16.7 Hertz
electricity needed by the train system. This will
be done using a traction current converter facility
to be built along with the power plant. With an
output of 413 megawatts, it is the largest facility
of its kind in the world, and is also the highestoutput
feed current unit in Deutsche Bahn’s grid.
Energy for the region
In addition to traction current, the Datteln 4 power
plant will be able to provide a total of 642 megawatts
to the region’s public electricity grid. This
means that the power plant will be utilized continuously
and effi ciently.
District heating for Datteln and the Ruhr area
For over 40 years, the Datteln power plant has
been rements with environmentally friendly district
heating. The power plant presents a special type
of environmental advantage: district heating is
provided with low fuel requirements. The plant’s
good overall energy profi le means that it saves a
great deal of primary energy. In the Ruhr area, this
leads to an additional improvement of the regional
CO 2 footprint.
Around 1,000 GWh environmentally friendly
district heating will be produced by the new
power plant Datteln 4. This provides around
100,000 housing units with heating, and is the
largest contribution of E.ON to grid supply in
the region. The basis for this is the principle of
com bined heat and power generation. Part of the
steam used to turn the turbines and generate
power is drawn off the turbine to be used for
district heating. This increases the fuel effi ciency
of the power plant to around 60 percent, and
decreases the emissions in the Ruhr area. Altogether
Datteln 4 will provide around 50 percent of the
district heating and take over the supply of
Recklinghausen, Herne and Bochum. Additionally
the power plant is able to deliver district heating
to Castrop-Rauxel and Dortmund-Bodelschwingh.
Hereby Datteln 4 will be one of the ten largest
heating power plants in Germany.
