Scholven power station is a 740-megawatt (MW) coal-fired power station in North Rhine-Westphalia, Germany. Additionally, the power station is the site of the 76 MW Buer power station.

Units D-F totaling 1,480 MW were retired in 2014. Units B-C are planned for closure in 2022 and will initially be replaced with a gas turbine.

Background

The mine-mouth plant began operating as a 50 MW plant in 1930, but was largely destroyed by a large number of bombing raids during World War II. Power generation resumed in 1955. From 1968 to 1975, the coal-fired Blocks B to E (370 MW each) and oil-fired blocks G and H were commissioned. In 1979 Block F, with 740 MW, was commissioned. In 1985 Buer district heating power plant of 76 MW net output was commissioned at the power station. In 2001-2003, the oil-fired units were decommissioned, and demolished in 2009.[1][2]

Coal-fired units D-F totaling 1,480 MW were retired in 2014.[3]

On July 14, 2021, Uniper announced that Unit C "will cease commercial electricity production as early as end of October 2022 and will be permanently decommissioned as of then."

Gas-fired capacity

In August 2018 Uniper said it plans to build new gas-fired units to replace the two remaining Scholven coal units, units B-C totaling 640 MW. The gas units are intended to initially supplement the coal units but fully replace them by 2022 with the power supplied to a nearby industrial customer.[4]

As part of the plan, Uniper has teamed up with German chemicals company Evonik to build a 15 km (10 mile) gas pipeline to connect Scholven to the network of Open Grid Europe.[5]

The new Scholven plant will consist of a 114 MWe/140 MWt natural-gas-fuelled twin-gas-turbine CHP facility, due for completion in 2022. Uniper says it intends to eventually replace the existing elderly coal-fired units at the site with gas-fuelled capacity.[6]

Construction on a 138 MWe unit was announced in 2020.[7]

As of July 2021, Uniper states that "the existing coal-fired power plant is to be transformed by autumn 2022 through the construction of a modern combined-cycle gas turbine (CCGT)."[8] After that, Uniper says it plans to convert the gas fired power plant to use 100 percent green hydrogen by 2030.[8]

Proposed coal expansion

In 2008, an 1100 MW expansion of the power station was proposed by E.ON Kraftwerke, with a notional commissioning date of 2014/15. In 2008 the project was designated by Power in Europe as being at the "pre-proposal" level. The newsletter noted that "reports surface of a further new coal plant project for E.ON, perhaps at this existing generation site."[9]

The new coal-fired unit at Scholven was never built.
