Compression of air creates heat; the air is warmer after compression. Expansion removes heat. If no extra heat is added, the air will be much colder after expansion. If the heat generated during compression can be stored and used during expansion, then the efficiency of the storage improves considerably. There are several ways in which a CAES system can deal with heat. Air storage can be , diabatic, , or near-isothermal.

Spain was an early leader in development of wind power, ranking second after Germany by installed capacity until 2006, when it was surpassed by the United States. In November 2009, a wind storm caused wind farms to produce a peak of 53% of total electricity demand (11.546 GW). This was surpassed in November 2011 with a capacity peak of 59% of power demand being generated by wind power.
