In order to secure a reliable energy supply for Southern Germany, the transmission system operators in Southern Hesse, Bavaria and Baden-Württemberg have put “grid stability systems”, each with a capacity of 300 MW, out for tender. They are due to be commissioned in 2022. RWE has looked into this option and submitted an offer for the Biblis power plant site.
On November 13th 2020 RWE Generation was awarded the contract for building and operating a gas-fired grid reserve plant in Biblis by transmission system operators Amprion. The new grid stability plant will be built just south of the current power plant site. It will provide a secure capacity of 300 megawatts and will come on stream by October 2022.
