FERC Reforms Target Grid Interconnection Backlog as Storage Delays Persist
U.S. interconnection queues fell to about 2,061 GW by the end of 2025 but remain above 2,000 GW, leaving battery storage projects exposed to multi-year delays. FERC Order No. 2023 has yielded measurable progress, including 1.9 GW of battery agreements in PJM’s first transition cycle, while developers and suppliers must continue tracking tariff and grid-operator changes.
