URL More about Herdecke Pumped Storage Power Plant
The Herdecke (or Koepchenwerk) Pumped Storage Power Plant was originally commissioned in 1930, but an accident caused by a broken pump in December 1980 led to the plant's closure. Between 1985 and 1989, RWE built and commissioned a new pumped storage plant adjacent to the old one. The power plant was later modernized at the cost of €25 million between May and September 2007. The plant uses roughly the same amount of energy in pumping mode (153,590 kW) as it creates in generating mode (153,000 kW).
This data has been validated by project staff through a review of publicly available information about the project, and verified by the project owner.
