U.S. natural gas storage capacity increased in 2024 ›

annual change in demonstrated peak capacity and working design capacity

Data source: U.S. Energy Information Administration, Form EIA-191, Monthly Underground Natural Gas Storage Report
Note: Measures of capacity reflect final revised values as published in the Underground Natural Gas Working Storage Capacity report.

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.
