Compressed Air Energy Storage

Responds quickly - Designed to be started and brought to full load in less than 10 minutes, eliminating the need for intermediate-load plants and providing a cost-effective way to meet spinning reserve requirements. 

CAES generation also has excellent load-following capability and exceptional part-load efficiency. 

Full compression can be available in less than five minutes to quickly absorb load rather than reducing your base load generation.

Flexible cycling options - The CAES plant allows for independent operation of the compression and expansion systems, allowing for simultaneous load absorption and balancing.

Generation efficiency - Relatively flat heat rate across all operating ranges, thus overall generation efficiency is near the same at 10 percent as it is at 100 percent.

Days of storage - The intermittency of renewables coupled with unpredictable weather patterns means the reality of long periods where balancing is paramount to absorbing renewables.
