📉 EIA Natural Gas Storage Report – Week Ending November 6, 2026: A Smaller-Than-Expected Build Keeps Winter Tightness in Focus

The U.S. Energy Information Administration reported a net injection of 61 billion cubic feet (Bcf) into underground storage for the week ending November 6, 2026, lifting total Lower 48 working gas to 3,862 Bcf, up from 3,801 Bcf the previous week. The build was smaller than

the prior week's 77 Bcf injection and came in below the consensus estimate of 67 Bcf — but it was still well above the five-year average injection of 40 Bcf for this week, with the heating season now underway as of November 1.

Stocks sit 92 Bcf, or 2.3%, below the same week last year, yet remain 75 Bcf, or 2.0%, above the five-year average of 3,787 Bcf — and within the five-year historical range. The direction of travel improved again this week: the surplus over the five-year average widened from 54 Bcf to 75 Bcf, and the year-over-year deficit narrowed from 109 Bcf to 92 Bcf. The picture, however, is essentially unchanged — the market enters winter with less gas than a year ago, but with a growing cushion relative to normal.

Key Storage Highlights

Working gas rose 61 Bcf for the week, down from 77 Bcf the previous week and below the 67 Bcf consensus estimate.
Total Lower 48 inventories stand at 3,862 Bcf.
Stocks are 92 Bcf (-2.3%) below the year-ago level of 3,954 Bcf.
Inventories are 75 Bcf (+2.0%) above the five-year average of 3,787 Bcf.
At 3,862 Bcf, total working gas remains within the five-year historical range.

Regional Storage Trends

South Central: +27 Bcf — the strongest regional injection again, lifting stocks to 1,235 Bcf. Salt caverns added 16 Bcf and nonsalt facilities added 12 Bcf.
Midwest: +18 Bcf — a solid build to 1,129 Bcf.
East: +12 Bcf — a steady addition to 938 Bcf.
Mountain: +2 Bcf — a minimal gain, to 262 Bcf.
Pacific: +2 Bcf — flipping back to an injection after last week's 1 Bcf withdrawal, the season's first regional draw, to 298 Bcf.

The South Central region deserves the closest look. Despite posting the largest regional build for a second straight week, it still carries the deepest year-over-year deficit of any region — 80 Bcf below last year's level and 4 Bcf under the five-year average. Salt

cavern stocks, the most flexible inventory in the system, sit 39 Bcf, or 11.1%, below year-ago levels and 19 Bcf below the five-year average. Gulf Coast storage sits at the crossroads of record LNG export demand and high-deliverability salt caverns that balance the market; when feedgas demand runs hot, this is where tightness shows first. The West, meanwhile, remains below last year despite this week's small builds — Mountain stocks are 9.7% below year-ago levels and Pacific stocks 7.2% below. The East and Midwest, by contrast, are

the comfortable regions: both sit above last year and above their five-year averages.

What This Means for Natural Gas Prices

On its face, today's print is mixed. A 61 Bcf build that beat the five-year norm by 21 Bcf and widened the surplus over average is bearish on the headline. But the miss against the 67 Bcf consensus — and a year-over-year deficit that still stands at 92 Bcf — keeps the market from getting comfortable. Gulf Coast salt storage remains deeply below year-ago levels, and the heating season has begun, leaving little room for a cold-weather surprise.

What the market is watching now:

Temperature forecasts — early-November weather has been mild, but one sustained cold run can move prices quickly.
LNG export volumes — feedgas demand keeps pulling gas away from Gulf storage.
Production trends — Lower 48 output has eased from record highs, and the recovery pace matters.
Pipeline maintenance — seasonal work can temporarily constrain flows into key consuming regions.
The first withdrawals of the season — the timing and size of the flip from injections to draws will set the winter tone.

Outlook for Energy Buyers

For commercial and industrial consumers, the message is straightforward: injection season is over, and the storage trajectory points to a tighter starting position for winter than last year.

Ending the first week of November at 3,862 Bcf leaves the market entering the heating season about 92 Bcf behind last year's level — a manageable gap, but one that narrows the margin for error if cold weather arrives early or lingers.

That makes the next few weeks the practical deadline for winter procurement decisions. Facilities with unhedged winter exposure should be reviewing hedges and contract terms now, while the market is still digesting a merely "adequate" storage picture — not after the first cold front arrives and volatility returns to the front of the curve.

PEM Perspective

This week's report is a reminder that headline storage numbers only tell half the story. Yes, 3,862 Bcf is above the five-year average — but a 92 Bcf year-over-year deficit, deepening Gulf Coast tightness, and a heating season now underway all point to a market with less room for error than a year ago. A solid build buys the market calm for now; it does not buy comfort for the winter. For energy buyers, the playbook is the same as ever at this point in the calendar: review your hedges, benchmark your contract terms, and prepare for volatility

before the market forces you to react to it.
