US Natural Gas Storage: The Market's Fuel Gauge
Lower-48 working gas in storage stands at 3,567 Bcf (EIA week ending 2026-10-09), up 67 Bcf on the week and above the ~3,509 Bcf 5-year norm for this week. Storage versus the 5-year average is the most-watched fundamental in the US gas market — here's how to read it.
The Storage Year
Injection season (Apr–Oct)
- Production exceeds demand; surplus gas is injected underground (depleted fields, aquifers, salt caverns).
- Weekly injections of 40–100+ Bcf are typical; hot summers cut injections via air-conditioning power burn.
- The market handicaps whether storage will reach a comfortable ~3,700+ Bcf by November.
Withdrawal season (Nov–Mar)
- Heating demand outstrips production; storage drains, sometimes 200+ Bcf in a single cold week.
- Deep cold with low storage is the price-spike recipe (Feb 2021: spot gas hit hundreds of dollars in Texas).
- End-of-winter level (late March) sets the tone for the following year's prices.

EIA weekly Lower-48 working gas in underground storage. The 5-year average is the mean of the nearest weekly report to the same date in each of the previous five years. Above-average storage weighs on prices; below-average supports them. The seasonal band as a chart: EIA fundamentals.

Gas Storage FAQ
How much natural gas is in storage right now?
Lower-48 working gas in underground storage is 3,567 Bcf as of the EIA week ending 2026-10-09 (up 67 Bcf on the week). That is roughly above the 5-year average of about 3,509 Bcf for this point in the year.
When does the natural gas storage report come out?
Thursdays at 10:30 a.m. Eastern. It reports net injections (spring–fall) or withdrawals (winter) for the prior week. Like the oil report, the market trades the surprise versus analyst expectations — a smaller-than-expected injection is bullish.
Why does storage matter so much for gas prices?
Gas demand is brutally seasonal but production is steady, so storage is the shock absorber: filled April–October, drained November–March. If storage looks inadequate heading into winter, prices rise until demand is rationed or more supply arrives — storage-vs-5-year-average is the single best fundamental gauge of tightness.
What is "working gas"?
The gas that can actually be withdrawn — total storage minus "base gas" that must stay in the field to maintain pressure. US working-gas capacity is roughly 4,700 Bcf; peak pre-winter fills usually reach 3,500–4,000 Bcf.
