Why Gas Prices Still Matter for Your Electricity Bill
Natural gas generates roughly 43% of US electricity. In every major grid market — ERCOT, PJM, ISO-NE, MISO, and CAISO — gas-fired units are the marginal price-setting resource during peak hours. When Henry Hub moves, your commercial electricity bill follows, typically with a 2–4 month lag as contracts reprice.
This is why the current $2.90 spot price matters. Despite the chaos of the most expensive ISO-NE winter on record and rising data center demand, the market is telling us that near-term natural gas supply is abundant. The question is how long it lasts.
The Winter That Didn’t Drain Storage
Winter 2025/2026 was a tale of two realities. In New England, it was a disaster — the coldest winter in 20 years drove ISO-NE wholesale energy costs to $6 billion, and pipeline-constrained regional prices spiked above $30/MMBtu on the Algonquin Citygate. But nationally, the picture is surprisingly benign:
- Storage above average: US working gas inventories are entering the April–October injection season above the 5-year average, thanks to a milder-than-expected winter in the South and West.
- Strong production: Domestic natural gas production remains at or near record levels, providing steady supply.
- Early injections: Some regions began net injections in late March, earlier than the traditional April start.
| Indicator | Current | EIA Forecast | Signal |
|---|---|---|---|
| Henry Hub Spot | $2.90/MMBtu | $3.80 avg | Below forecast |
| Working Gas Storage | Above 5-yr avg | Comfortable | Bullish supply |
| LNG Export Demand | Growing | +2.1 Bcf/d | Upside risk |
| Summer Power Burn | TBD | Weather-dependent | Key variable |
What Could Push Prices Higher
- LNG export expansion: New liquefaction capacity coming online in 2026 will add approximately 2.1 Bcf/d of additional export demand.
- Hot summer: Above-normal cooling degree days would spike power burn and draw down storage during injection season.
- Data center power burn: Every additional GW of data center load running 24/7 on gas-fired generation adds roughly 0.15 Bcf/d of incremental demand.
What Could Keep Prices Low
- Record production: Appalachian and Permian associated gas providing steady supply growth.
- Mild shoulder season: April–May temperature forecasts suggest moderate weather nationally.
- Storage buffer: Starting injection season above the 5-year average reduces volatility risk through mid-summer.
Commercial Procurement Action Items
- Gas-indexed buyers: The current $0.90/MMBtu discount to the EIA forecast represents a natural entry point. Consider locking 50–70% of expected volume at current index levels.
- Fixed-rate electricity buyers: If your contract includes a gas adjustment clause, request a blended rate capturing Q2 2026 pricing before summer demand materializes.
- Northeast buyers: Regional basis differentials remain elevated. Budget for $5–8/MMBtu premiums on Transco Z6 and Algonquin Citygate in winter planning.
- Hedge timing: The April–June window historically offers the lowest gas prices of the year. Review your hedge book now.
