Compressed Air Energy Storage (CAES)
Compressed airstorage (CAES) is a way to store energy generated at one time for use at another time. At utility scale, energy generated during periods of low energy (off-peak) can be released to meet higher demand (peak load) periods.
Since the 1870's, CAES systems have been deployed to provide effective, on-demand energy for cities and industries. While many smaller applications exist, the first utility-scale CAES system was put in place in the 1970's with over 290 MW nameplate. CAES offers the potential for small-scale, on-site energy storage solutions as well as larger installations that can provide immense energy reserves for the grid.
