Underground working natural gas storage capacity in the Lower 48 states increased in 2024 according to our latest data. We calculate natural gas storage capacity in two ways: demonstrated peak capacity and working gas design capacity. Both increased in 2024. Underground natural gas storage provides a source of energy when demand increases, balancing U.S. energy needs. In 2024, demonstrated peak capacity rose 1.7%, or 70 billion cubic feet (Bcf), to 4,277 Bcf, while working gas design capacity increased slightly by 0.1%, or 3 Bcf.
Demonstrated peak capacity is the sum of the largest volume of working gas stored in each storage field during the previous five-year period, regardless of when the peaks occurred. Demonstrated peak capacity is typically less than working gas design capacity because it relates to actual usage rather than
