Overview
- RWE launched construction of a 400 MW, 700 MWh lithium‑iron‑phosphate battery made up of more than 200 containers with about 850,000 cells.
- The company targets the start of commercial operation in early 2028, following installation work beginning in the coming months.
- RWE plans a 55‑hectare solar park at the site and says it has received approval to build a gas‑fired peaker plant for periods of low renewable output.
- The investment totals roughly €230 million, with the project leveraging the former nuclear plant’s existing grid connection.
- The milestone comes during a national storage surge, with transmission operators reporting roughly 650 large‑battery connection requests totaling about 226 GW and experts flagging integration challenges.
