U.S. natural gas inventories in underground storage ended winter at 3-yr low

After a relatively warm start to the 2024–2025 winter heating season (November–March), colder-than-normal temperatures across much of the United States in January and February resulted in increased consumption of natural gas and more withdrawals from U.S. natural gas storage than normal.

By the end of March, the least amount of natural gas was held in U.S. underground storage in the Lower 48 states since 2022, with inventories 4% lower than the previous 5-yr average for that time of year, according to the U.S. Energy Information Administration’s (EIA’s) Weekly Natural Gas Storage Report.

In January and February, the colder-than-normal temperatures across the country led to increased natural gas consumption in the residential, commercial and electric power sectors. Consumption in the combined residential and commercial sectors in January and February averaged 97 Bft3d, 16% more compared with the same period in 2024. A cold snap in the second half of January resulted in the fourth-largest reported weekly withdrawal from storage at 321 Bft3 for the week ending January 24. Natural gas withdrawals in January and February combined totaled nearly 1,650 Bft3, or 33% more than the 5-yr (2020–2024) average for those months.

Working natural gas inventories in the Mountain and Pacific regions at the end of March exceeded the 5-yr average by 53% and 18%, respectively, while inventories elsewhere were less than the 5-yr average. At the start of the heating season in November, natural gas inventories in all regions in the Lower 48 states were above the 5-yr average. As the winter progressed, inventories in the East and Midwest regions fell below the 5-yr average by the end of December, and inventories in the South Central region were less than the 5-yr average by the end of January.

Warmer-than-normal temperatures in March resulted in net natural gas injections into storage for the month, signaling an earlier start to the injection season than is typical. Working natural gas in underground storage facilities in the Lower 48 states totaled 1,786 Bft3 as of March 31, 2025.
