Vattenfall said on Thursday it has received approval from Brunsbuttel City Council to advance planning for a 254-megawatt battery with 700 megawatt-hours of storage at the site of the former nuclear power plant.
The company said the battery is expected to go into operation by 2028 at the latest, pending a final investment decision. A new substation will also be built to connect the facility to the grid.
“This is very good news for Vattenfall and for the region. Batteries are rapidly becoming an essential part of the energy system in Germany,” Claus Wattendrup, head of solar and batteries at Vattenfall, said. “With the existing space and the existing grid connection, the site in Brunsbuttel offers very good conditions for the construction of the battery storage system.”
Johanne Robke, head of the Brunsbuttel battery project, added: “The city’s resolution on the statutes is an important milestone for us so that the battery can become a reality.”
The approval follows extensive planning and consultations with local authorities and stakeholders, Vattenfall said.
