Vattenfall plans 700 MWh battery system at former German nuclear site

Vattenfall is planning a 254 MW / 700 MWh battery energy storage system of capacity at the former Brunsbüttel nuclear power plant site, which is currently being dismantled. The energy company has received approval from the Brunsbüttel city council, which voted in favour of the zoning plan, Vattenfall said on Friday. The decision marks an important step for the project’s development.

The site is located in Germany’s north, close to both the Danish border, the North Sea, and close to the port of Hamburg.

Vattenfall has not yet taken the final investment decision. If the company proceeds, it intends to build the battery system and a new substation for grid connection. Under current plans, the system is scheduled to be commissioned no later than 2028.

“The Brunsbüttel site offers very good conditions for the battery project, with available land and an existing grid connection,” said Claus Wattendrup, who heads Vattenfall’s solar and battery division. Johanne Robke, project lead for the Brunsbüttel battery, highlighted the constructive cooperation with authorities and the city. All parties, she said, are focused on finding workable solutions. “The city’s resolution is an important milestone that allows the battery to become a reality.”
