Vattenfall contracts Fluence for German storage facility

Vattenfall has commissioned Fluence Energy to build a large-scale battery storage installation at a former nuclear site in Germany.

By the CEII Desk, from reporting by Power Technology

Key points

  • The facility will feature a capacity exceeding 1GWh and an output of 254MW.
  • Construction is scheduled to begin in 2027 with operations starting by late 2028.
  • The project utilizes Fluence's Gridstack Pro platform to manage grid fluctuations.

What happened

According to Power Technology, Vattenfall awarded a contract to Fluence Energy to construct and service a major battery energy storage plant in Brunsbüttel, Germany, on the grounds of a retired nuclear station. The installation will deliver an output of 254MW alongside a storage capacity above 1GWh. Vattenfall approved the final investment decision for the initiative in September, with construction activities slated to commence in 2027 and grid integration anticipated by the close of 2028.

Why it matters

Power Technology reported that the four-hour storage system is engineered to manage electricity supply variations driven by rising solar and wind generation. Claus Wattendrup, head of solar and batteries at Vattenfall, stated that the development helps reinforce energy network stability and assists the shift away from fossil fuels, as quoted by Power Technology. Once finished, the installation will rank among the largest battery storage sites in the country and nearly double Vattenfall's current storage capacity.
