Underground Gas Storage Summary
Natural gas and liquefied petroleum gas (LPG) are stored underground to help meet demand for gas while providing a relatively stable market for produced gas. Gas is injected into wells during the summer when consumer demand is low, and withdrawn during the peak winter season. Natural gas and LPG can be stored in depleted gas or oil reservoirs, salt cavities, and mined underground caverns.
Presently, there are 26 natural gas storage facilities and 3 LPG storage facilities in New York, concentrated in the central and western regions near both gas production fields and gas transmission facilities.
