EIA Natural Gas Storage Report: This Week's Data

What This Means: Commercial Buyer Analysis

EIA reported a 15 Bcf injection for the week ending August 21, lifting Lower 48 working gas to 3,184 Bcf. KilowattLogic calculates that the build was 1 Bcf smaller than the prior report and the five-year surplus narrowed by 18 Bcf to 167 Bcf, while the year-over-year deficit widened by 2 Bcf to 30 Bcf. Inventories remain 5.5% above the five-year average, which is useful national context without guaranteeing lower delivered gas or electricity rates. East injected 19 Bcf and Midwest injected 18 Bcf, while Pacific withdrew 3 Bcf and South Central withdrew 19 Bcf; South Central salt alone withdrew 20 Bcf. Gulf Coast, western, LNG-linked, and basis-sensitive buyers should keep heat, production, feedgas, power-sector demand, 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.
