What The July 30 Report Shows
EIA reported a 28 Bcf net injection into Lower 48 storage for the week ending July 24, bringing total working gas to 3,084 Bcf. Stocks were 32 Bcf below the year-earlier level and 185 Bcf above the five-year average of 2,899 Bcf.
The injection was 4 Bcf smaller than the prior week's 32 Bcf build. The five-year surplus widened by 2 Bcf, while the year-over-year deficit widened by 16 Bcf. Buyers should read those comparisons together: the refill path remains above normal, but it is not uniformly loose across timeframes or regions.
| Region | Working Gas | Weekly Change | Vs 5-Yr Avg | Vs Year Ago |
|---|---|---|---|---|
| East | 654 Bcf | +23 Bcf | +3.6% | +0.8% |
| Midwest | 789 Bcf | +23 Bcf | +6.6% | +3.5% |
| Mountain | 238 Bcf | -2 Bcf | +17.2% | -1.7% |
| Pacific | 307 Bcf | -7 Bcf | +16.3% | +2.0% |
| South Central | 1,096 Bcf | -9 Bcf | +3.1% | -5.7% |
| South Central salt | 303 Bcf | -14 Bcf | +9.0% | -4.4% |
| South Central nonsalt | 793 Bcf | +5 Bcf | +1.1% | -6.0% |
Commercial Buyer Read
| Signal | Market Read | Buyer Move |
|---|---|---|
| 28 Bcf injection | The Lower 48 build slowed by 4 Bcf from the July 23 report while total working gas advanced to 3,084 Bcf. | Keep heat, LNG feedgas, production, and power-sector burn in the next procurement check instead of treating the weekly build as a standalone price call. |
| 185 Bcf above five-year average | The national surplus widened by 2 Bcf and remained 6.4% above the 2021-25 average. | Use the surplus as constructive national supply context, then test regional basis, delivery tariffs, and contract pass-through terms separately. |
| 32 Bcf below last year | The year-over-year deficit doubled from 16 Bcf in the prior report even as the five-year surplus widened. | Avoid describing the balance as uniformly loose when the year-over-year and five-year comparisons still point in different directions. |
| Three regional withdrawals | Mountain withdrew 2 Bcf, Pacific 7 Bcf, and South Central 9 Bcf while East and Midwest each injected 23 Bcf. | Keep Gulf Coast, LNG-linked, western, and basis-sensitive exposures separate from the Lower 48 headline. |
How To Use The Number
- Keep the dates attached: this is the July 30, 2026 report for the week ending July 24.
- Separate national inventory from regional basis: South Central withdrew 9 Bcf, including a 14 Bcf salt withdrawal, while its nonsalt stocks remained 6.0% below last year.
- Connect gas and power carefully: storage can influence gas-indexed wholesale power risk, but delivery tariffs, capacity, transmission, load shape, and contract language decide the invoice.
What Not To Infer
- A 28 Bcf injection does not guarantee lower delivered natural gas or electricity rates.
- A national five-year surplus does not remove local basis, pipeline-constraint, LNG-feedgas, or high-demand risk.
- Weekly storage data is not a supplier quote and should not be converted into one without the customer's tariff class, load shape, and contract terms.
