Compressed Air Energy Storage (CAES) is a technology that has been in use since the 1970''s. CAES compresses air using off-peak, lower cost and/or green electricity and stores the air in underground salt caverns until needed. When the pressurized air is released, it is heated and run through a gas turbine, combined with the fuel source, to
