Vattenfall has taken a final investment decision to build a large 254 MW battery storage facility with 1000 MWh capacity at the former Brunsbüttel nuclear plant site in Germany, expected operational by 2028. This project will nearly double Vattenfall’s existing battery capacity and supports Germany’s energy transition by enhancing grid flexibility and storage.

This Wire brief sits within Fusion42's coverage of Clean Energy.

◆ ◆ The Wire takeaway

Large standalone batteries are becoming a cornerstone in Germany’s grid; you supplying flexibility or grid services can find new demand and reduce market risk by linking your product to grid operators’ decarbonisation goals.
