Building and operating a grid stabilization plant

To ensure grid stability and security of supply, additional generation facilities ("special grid-related equipment in accordance with Section 11 (3) EnWG") are required as part of the Energiewende. EnBW is currently constructing such a grid stability facility at its power plant site in Marbach am Neckar. Following completion of the approval process in accordance with the Federal Immission Control Act (BImSchG) in July 2020, the plant is currently under construction. Due to delays, commissioning is targeted for 2024.
