EIA Natural Gas Storage Report: This Week's Data
Commercial analysis of the latest EIA Weekly Natural Gas Storage Report. EIA publishes the report each Thursday at 10:30 AM ET; KilowattLogic updates this page after the current release is verified. The next scheduled report is September 17, 2026.
For the week ending September 4, 2026, EIA reported a net injection of 40 Bcf into natural gas storage. Total working gas in storage stands at 3,254 Bcf, which is 4.8% above the five-year average. Year-over-year, inventories are 79 Bcf (2.4%) below the same week in 2025.
What This Means: Commercial Buyer Analysis
EIA reported a 40 Bcf injection for the week ending September 4, lifting Lower 48 working gas to 3,254 Bcf. KilowattLogic calculates that the build increased by 10 Bcf, or about 33%, from the prior report, while the five-year surplus narrowed by 12 Bcf to 148 Bcf and the year-over-year deficit widened by 29 Bcf to 79 Bcf. Inventories remain 4.8% above the five-year average, which is useful national context without guaranteeing lower delivered gas or electricity rates. East and Midwest injected 38 Bcf combined, Mountain and Pacific injected 8 Bcf, and South Central withdrew 7 Bcf, including an 11 Bcf salt-storage draw. Gulf Coast, LNG-linked, and basis-sensitive buyers should keep production, feedgas, power-sector demand, weather, and delivery constraints in the decision.

About This Report
The EIA Weekly Natural Gas Storage Report is published every Thursday at 10:30 AM ET by the U.S. Energy Information Administration. It measures the net change in underground natural gas inventories during the prior week.
This is one of the most closely watched weekly fundamental data points in energy markets. Large injections can support a looser supply read, while withdrawals or narrowing surpluses can tighten the market read. Because natural gas often sets the marginal cost of electricity in wholesale power markets including PJM, ERCOT, NYISO, ISO-NE, MISO, CAISO, and SPP, the storage report has direct implications for gas-indexed electricity risk. It is still not a delivered-rate forecast by itself.
