Battery storage

Clearway is a growing battery storage developer, owner, and operator, working across both regulated and deregulated markets.

Battery storage in renewable energy

Battery energy storage is critical to the clean energy transition. As costs continue to decline, battery storage will continue to play a growing role in renewable energy portfolios, storing excess solar and wind generation to deploy onto the grid when it’s needed most.

With over 12 GW operating and in development across 16 states, Clearway’s growing portfolio of paired and standalone storage contributes to grid reliability nationwide.

How battery energy storage benefits everyone.


Storing energy for delivery when and where it’s needed creates grid resiliency, stabilizes power supply costs, and enhances renewable availability.
