Germany’s Federal Network Agency has launched the first auction under the new Electricity Supply Security and Capacity Act, with bids for new dispatchable generation and long-duration energy storage due by Sept. 8. The first round covers 4.5GW of capacity, with successful bidders receiving capacity payments in exchange for keeping facilities available for 15 years. Battery storage is eligible only if it can discharge continuously for at least 10 hours, with a reduction factor of 0.58 for 10-hour systems and 0.85 for 20-hour systems. Batteries must also achieve 100% technical availability, at least 92% round-trip efficiency, and meet local-content requirements for key components such as cells and inverters. Results are expected on Nov. 3.
