What The August 27 Report Shows
EIA reported a 15 Bcf net injection into Lower 48 storage for the week ending August 21, bringing total working gas to 3,184 Bcf. Stocks were 30 Bcf below the year-earlier level and 167 Bcf above the five-year average of 3,017 Bcf. EIA classifies total storage as within the five-year historical range.
Compared with the August 20 report, KilowattLogic calculates that the weekly build fell by 1 Bcf and the five-year surplus narrowed by 18 Bcf. The year-over-year deficit widened by 2 Bcf. The national balance remains above normal, but the narrowing cushion and regional withdrawals argue against turning the headline into a one-direction price call.
| Region | Working Gas | Weekly Change | Vs 5-Yr Avg | Vs Year Ago |
|---|---|---|---|---|
| East | 727 Bcf | +19 Bcf | +5.1% | +3.1% |
| Midwest | 866 Bcf | +18 Bcf | +5.9% | +4.5% |
| Mountain | 238 Bcf | +1 Bcf | +11.2% | -6.3% |
| Pacific | 293 Bcf | -3 Bcf | +11.4% | -1.7% |
| South Central | 1,061 Bcf | -19 Bcf | +3.0% | -5.9% |
| South Central salt | 248 Bcf | -20 Bcf | +2.1% | -9.2% |
| South Central nonsalt | 813 Bcf | +1 Bcf | +3.2% | -4.8% |
Commercial Buyer Read
| Signal | Market Read | Buyer Move |
|---|---|---|
| 15 Bcf injection | The Lower 48 build was 1 Bcf smaller than the prior report and lifted working gas to 3,184 Bcf. | Treat the weekly refill pace as one signal; keep weather, production, LNG feedgas, and power burn in the procurement read. |
| 167 Bcf above five-year average | KilowattLogic calculates that the national surplus narrowed by 18 Bcf from the August 20 report. | Use the remaining 5.5% cushion as national context, then test local basis, delivery tariffs, and contract pass-through terms separately. |
| 30 Bcf below last year | KilowattLogic calculates that the year-over-year deficit widened by 2 Bcf; inventories trailed August 21, 2025 by 0.9%. | Describe the balance as above the five-year average but below last year; neither comparison replaces the other. |
| Northern builds offset Gulf withdrawals | East and Midwest injected 37 Bcf combined, while Pacific withdrew 3 Bcf and South Central withdrew 19 Bcf; South Central salt alone withdrew 20 Bcf. | Keep Gulf Coast, western, LNG-linked, and basis-sensitive exposure separate from the national inventory headline. |
What Not To Infer
- A 15 Bcf injection does not guarantee higher or lower delivered natural gas or electricity rates.
- A national surplus does not remove local basis, pipeline-constraint, LNG-feedgas, or high-demand risk.
- Weekly storage data is not a supplier quote; tariff class, load shape, delivery charges, and contract terms still determine the bill.
