Zelestra and Centrica Energy agree toll for 99MW/297MWh Germany BESS
AI-summarised brief · reviewed before publication
Zelestra has secured a long‑term tolling agreement with Centrica Energy for its 99 MW/297 MWh Hilgermissen battery energy‑storage system (BESS) in Lower Saxony, Germany. The deal allows Zelestra to build, own and operate the standalone BESS while Centrica trades and optimises the capacity for a fixed fee, effectively renting the asset. Construction is slated to begin in 2027, with full operations expected in the second half of 2028. The agreement follows a series of similar BESS offtake deals across Europe.
💡 Why It Matters
- · The partnership demonstrates how European developers are monetising storage assets through long‑term tolling, a model that can accelerate grid‑scale deployment and support Germany’s renewable targets.
- · It also signals Centrica’s strategic shift toward owning optimisation rights rather than owning physical infrastructure.
