Germany advances nuclear decommissioning and battery storage plans

The German government has provided updates on the decommissioning process of the country's nuclear power plants. For the three plants shut down in April 2023—Emsland, Isar 2, and Neckarwestheim 2—decommissioning and dismantling permits were granted between April 2023 and September 2024. While reactor cores have been unloaded and dismantling of components like piping and turbine parts has begun, these facilities are not yet completely free of nuclear fuel.

Other plants, including Grafenrheinfeld, Philippsburg 2, Grohnde, and Brokdorf, are further along in the process and are already free of fuel rods. In Grafenrheinfeld and Philippsburg 2, dismantling of large components such as reactor pressure vessels and steam generators is underway, and cooling towers have already been demolished.

In a related development at the decommissioned Neckarwestheim site, energy company EnBW plans to construct a large-scale battery storage facility with a capacity of up to 1,000 megawatt-hours. The project aims to utilize the existing high-voltage grid connection left behind by the nuclear plant, bypassing the lengthy wait for new grid access. This follows a similar model in Philippsburg, where EnBW is building a 400 megawatt/800 megawatt-hour storage system.
