EIA: Gas storage capacity increased in 2024 in U.S., declined in South Central

Underground working natural gas storage capacity in the lower 48 states increased last year, according to the latest data from U.S. Energy Information Administration.  EIA calculates natural gas storage capacity in two ways: demonstrated peak capacity and working gas design capacity.  Both increased in 2024.

Demonstrated peak capacity, the sum of the largest volume of working gas stored in each storage field during the previous five years, rose 1.7 percent or 70 billion cubic feet to 4,277 Bcf.  Design capacity increased slightly by 0.1 percent or 3 Bcf.  Design capacity increased 7 Bcf in the Mountain region to offset declines elsewhere.  Design capacity decreased slightly in 2024 in South Central region.
