U.S. battery storage reaches 52 GW as developers line up another 54 GW by 2028

The reported U.S. storage pipeline points to another 54 GW through 2028, including large additions expected over the next two and a half years. That matters for solar because batteries increasingly determine whether midday PV output can be shifted into evening demand and grid-service markets. Faster storage deployment can reduce curtailment risk, but it also raises pressure on interconnection queues, supply chains and market rules for flexible capacity.
