CAES for grid-scale storage

Compressed Air Energy Storage is a method of storing energy for later use—similar in purpose to batteries, but very different in scale and operation.

Stores excess renewable electricity

Energy CaptureExcess electricity—often from renewable sources like wind or solar—is used to power large compressors.

Supports grid stabilization

CAES helps solve this issue by capturing excess energy when supply is high and releasing it when demand spikes. The technology provides long-duration energy storage, supports grid stabilization, helps meet peak demand, and reduces reliance on fossil fuel peaker plants.
