US energy storage additions hit record 20.2 GWh in second quarter

The reported Q2 figure points to a new high for US storage deployment, with batteries increasingly paired with solar and used for capacity, peak shifting and grid reliability. SolarQuarter says the 2030 forecast has been lifted to 683 GWh, signalling stronger expectations for utility-scale procurement and interconnection-driven storage demand. The update matters for solar developers because storage growth is becoming a prerequisite for absorbing midday PV output and serving evening peaks. It also indicates that policy, grid queues and battery supply will shape the next stage of US solar expansion.
