Gelsenkirchen-Scholven has been an important industrial location for the state of North Rhine-Westphalia for over 100 years. The Scholven colliery was sunk in 1908. This also marked the birth of the Scholven power plant. Initially, the power plant only produced electricity to supply the colliery. But as time went on, more and more industrial customers were added, making Scholven Germany's largest coal-fired power plant and one of the largest in Europe during the mid-1960s. This has always been the heart of the Ruhr area.
Even today, the Scholven power plant and the Buer district heating power plant make a major contribution to security of supply in the European electricity network. Scholven power plant and its associated production locations in Gladbeck-Zweckel, Marl, Recklinghausen and Westerholt are reliable suppliers of electricity, district heating and process steam for the region. The three units B, C and CHP generate 762 MW (net) of electricity. Units D, E and F were taken out of service at the end of 2014. Additionally, up to 250 MW are generated in the form of steam for the surrounding industry and district heat for more than 100,000 homes in the region. For the industry in the northern Ruhr area Scholven power plant is a reliable partner for the supply of process steam, electricity and compressed air. Together with its customers, it contributes significantly to the economic success of the region.

Co-firing of oil pellets
The Scholven power plant uses oil pellets in the single-digit percentage range for co-firing in addition to hard coal as a fuel. In November 2018, Uniper decided to increase the measurement frequency by means of additional individual emission measurements in order to meet the demand for even greater transparency in the co-firing of oil pellets in the Scholven power plant. The pollutant content in the oil pellets, which are purchased from the neighbouring Ruhr Oel GmbH refinery, is already being monitored in the course of incoming inspections. The previous annual publications on the continuous emission measurements at the chimney and the additional individual measurements for certain parameters, including vanadium and nickel, will now be carried out every two months.
Uniper Kraftwerke GmbH (UKW) intends to replace the existing coal-fired plants at the Scholven site, whose service life is gradually coming to an end, with natural gas-fired plants in the future.
In order to maintain the location and secure jobs - also in the surrounding industry - the location is to be developed with natural gas in a future-proof manner in order to be able to continue to guarantee the supply of the surrounding industry with electricity and steam as well as the supply areas of Uniper Wärme GmbH with district heating. In order to connect the Scholven power plant site to the natural gas pipeline network of Open Grid Europe GmbH (OGE) in the Dorsten area, UKW plans to build a new natural gas pipeline that will be largely bundled with existing pipelines and traffic routes.
Construction work on the combined heat and power (CHP) plant with two gas turbines and a steam boiler at the Scholven site is scheduled to begin in 2019 and to be completed by 2022. The conversion of the site to gas will not only reduce emissions of substances such as CO2 massively. Noise pollution from the plant itself and from supply trucks will also be significantly reduced, as the gas can in future be delivered by pipeline. Construction is to begin immediately after approval has been granted.
