Gas Storage Is Set to Enter Winter at Its Highest Level Since 2016
The EIA projects 3,985 billion cubic feet in inventory at the end of October. Its Henry Hub forecast for 2026 is $3.44 per million BTU, and for the third quarter alone it cut the number by 50 cents in a month.
The short answer
- The Energy Information Administration said on August 11, 2026 that it expects U.S. natural gas inventories to reach 3,985 billion cubic feet in October - the highest level entering a winter since 2016.
- The August Short-Term Energy Outlook forecasts Henry Hub spot prices averaging $3.44 per million BTU in 2026 and $3.31 in 2027. The third-quarter 2026 forecast was cut to $2.87, down 50 cents from the July outlook.
- The EIA attributes the build to higher domestic production and to reduced LNG feedgas demand during maintenance at Freeport LNG, leaving South Central storage above its five-year average at the end of July.
- LNG exports are forecast at 17.4 billion cubic feet a day in 2026 and 18.6 in 2027; U.S. crude production at 13.8 million barrels a day in 2026 and 14.2 in 2027; Brent at $87 a barrel in 2026 and $69 in 2027.
Natural gas inventories are a seasonal ledger. Gas goes into storage through the spring and summer and comes out through the winter, and the level reached at the end of October is the cushion the country carries into the heating season. The Energy Information Administration expects that number to be 3,985 billion cubic feet this year, the highest going into a winter since 2016.
More natural gas in inventories in the fall season provides a cushion for increased heating-related consumption during the winter.
Why the surplus built
Two things pushed gas into storage rather than out of it. Domestic production increased. And feedgas demand from liquefied natural gas terminals fell during maintenance at Freeport LNG - gas that would otherwise have been chilled and shipped stayed in the domestic system. The EIA notes the effect was concentrated enough that South Central storage sat above its five-year average at the end of July.
What that has done to the price forecast
- Henry Hub spot price: $3.44 per million BTU forecast for 2026, $3.31 for 2027
- Third quarter 2026 alone: $2.87 per million BTU, a cut of 50 cents from the July outlook
- U.S. LNG exports: 17.4 billion cubic feet a day in 2026, rising to 18.6 in 2027
- U.S. crude oil production: 13.8 million barrels a day in 2026, 14.2 million in 2027
- Brent crude: $87 a barrel in 2026, $69 in 2027
The demand side has moved too
The August outlook also revised down what the EIA expects electricity demand to do. A pause in data centre growth in Texas cut its 2027 electricity demand growth forecast from 14% to 6% - a large revision, and one that matters for gas because gas-fired generation is what typically meets incremental load. On the coal side the EIA forecasts 102 million short tons of exports in 2026. On the oil side it continues to note transit constraints at the Strait of Hormuz affecting Middle East production.
Why it matters
Storage entering winter is the main buffer between a cold month and a price spike. A larger cushion does not guarantee lower heating bills - a severe winter draws it down quickly, and residential bills depend on local delivery charges as much as on the Henry Hub benchmark - but it changes the starting position. The EIA updates the Short-Term Energy Outlook monthly, and the storage estimate will be revised as injection data arrives.
