Behind-the-Meter Batteries Strengthen Grid Reliability And Capacity

Utilities and customers are adopting behind-the-meter (BTM) batteries and aggregation programs like Customer Battery Energy Sharing (CBES) to bolster grid reliability and flexibility. Analysts say modest load flexibility and expanded BTM participation could unlock over 100 GW of capacity, and 75% of new U.S. grid capacity in Q2 2025 came from battery storage. These dispatchable assets reduce peak demand and defer costly firm capacity additions.
