What The August 20 Report Shows
EIA reported a 16 Bcf net injection into Lower 48 storage for the week ending August 14, bringing total working gas to 3,169 Bcf. Stocks were 28 Bcf below the year-earlier level and 185 Bcf above the five-year average of 2,984 Bcf. EIA classifies total storage as within the five-year historical range.
Compared with the August 13 report, KilowattLogic calculates that the weekly build fell by 20 Bcf and the five-year surplus narrowed by 13 Bcf. The year-over-year deficit widened by 3 Bcf. The national balance remains above normal, but the slower weekly refill and regional withdrawals argue against turning the headline cushion into a one-direction price call.
| Region | Working Gas | Weekly Change | Vs 5-Yr Avg | Vs Year Ago |
|---|---|---|---|---|
| East | 708 Bcf | +15 Bcf | +5.0% | +2.9% |
| Midwest | 848 Bcf | +19 Bcf | +6.7% | +4.7% |
| Mountain | 237 Bcf | -2 Bcf | +11.8% | -7.1% |
| Pacific | 296 Bcf | -4 Bcf | +12.5% | -2.0% |
| South Central | 1,080 Bcf | -13 Bcf | +3.8% | -5.5% |
| South Central salt | 268 Bcf | -18 Bcf | +6.3% | -5.6% |
| South Central nonsalt | 812 Bcf | +5 Bcf | +2.9% | -5.5% |
Commercial Buyer Read
| Signal | Market Read | Buyer Move |
|---|---|---|
| 16 Bcf injection | The Lower 48 build was 20 Bcf smaller than the prior report, but still lifted working gas to 3,169 Bcf. | Treat the slower refill pace as one weekly signal; keep weather, production, LNG feedgas, and power burn in the procurement read. |
| 185 Bcf above five-year average | KilowattLogic calculates that the national surplus narrowed by 13 Bcf from the August 13 report. | Use the remaining 6.2% cushion as national context, then test local basis, delivery tariffs, and contract pass-through terms separately. |
| 28 Bcf below last year | KilowattLogic calculates that the year-over-year deficit widened by 3 Bcf; inventories trailed August 14, 2025 by 0.9%. | Describe the balance as above the five-year average but below last year; neither comparison replaces the other. |
| Regional withdrawals offset northern builds | East and Midwest injected 34 Bcf combined, while Mountain, Pacific, and South Central withdrew 19 Bcf; South Central salt alone withdrew 18 Bcf. | Keep Gulf Coast, western, LNG-linked, and basis-sensitive exposure separate from the national inventory headline. |
What Not To Infer
- A 16 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.
