What The September 3 Report Shows
EIA reported a 30 Bcf net injection into Lower 48 storage for the week ending August 28, bringing total working gas to 3,214 Bcf. Stocks were 50 Bcf below the year-earlier level and 160 Bcf above the five-year average of 3,054 Bcf. EIA classifies total storage as within the five-year historical range.
Compared with the August 27 report, KilowattLogic calculates that the weekly build doubled from 15 Bcf, while the five-year surplus narrowed by 7 Bcf and the year-over-year deficit widened by 20 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 | 753 Bcf | +26 Bcf | +6.1% | +3.0% |
| Midwest | 890 Bcf | +24 Bcf | +5.7% | +4.0% |
| Mountain | 236 Bcf | -2 Bcf | +8.8% | -7.1% |
| Pacific | 285 Bcf | -8 Bcf | +8.4% | -3.4% |
| South Central | 1,051 Bcf | -10 Bcf | +2.8% | -6.8% |
| South Central salt | 238 Bcf | -10 Bcf | +0.4% | -12.8% |
| South Central nonsalt | 813 Bcf | 0 Bcf | +3.6% | -5.0% |
Commercial Buyer Read
| Signal | Market Read | Buyer Move |
|---|---|---|
| 30 Bcf injection | The Lower 48 build doubled from the prior 15 Bcf report and lifted working gas to 3,214 Bcf. | Treat the faster refill pace as one signal; keep weather, production, LNG feedgas, and power burn in the procurement read. |
| 160 Bcf above five-year average | KilowattLogic calculates that the national surplus narrowed by 7 Bcf from the August 27 report. | Use the 5.2% cushion as national context, then test local basis, delivery tariffs, and pass-through terms separately. |
| 50 Bcf below last year | KilowattLogic calculates that the year-over-year deficit widened by 20 Bcf from the prior report. | Describe the balance as above the five-year average but below last year; neither comparison replaces the other. |
| Northern builds, southern and western draws | East and Midwest injected 50 Bcf combined, while Mountain, Pacific, and South Central withdrew 20 Bcf. | Keep Gulf Coast, western, LNG-linked, and basis-sensitive exposure separate from the national inventory headline. |
What Not To Infer
- A 30 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.
