US summer gas burn stays flat as mild weather caps ERCOT and MISO cooling demand

US summer gas burn stays flat as mild weather caps ERCOT and MISO cooling demand NYMEX Henry Hub front-month holds near $3.20 as early-summer power demand undershoots, even as EIA outlooks point to record gas-fired generation later this decade. NYMEX Henry Hub front-month is holding near $3.20 as of Friday's close (2026-06-20), little changed, after early-summer gas burn across the biggest US power markets undershot the bullish cases some traders had carried into June.² Natural gas futures had faltered for the first time that month on Wednesday (2026-05-20) as weather demand eased.³ Gas-fired power is the single largest source of US gas consumption, which makes it the swing variable for this year's storage path. With output climbing into soft demand, the surplus widens. EIA's Short-Term Energy Outlook put Lower 48 marketed production at 117.2 Bcf/d in the first quarter of 2026, up 4% from a year earlier, and forecast full-year output rising another 3%.¹ Enbridge launched an open season to revive a proposed expansion of its Algonquin transmission system into New England, Natural Gas Intelligence reported on 2026-05-20, a sign that pipeline limits still throttle the flow of gas to eastern demand.³ But the near-term price signal is coming off the weather tape. Warmer-than-normal forecasts for the east and west coasts lifted futures on Monday (2026-05-18), then that support faded by Wednesday (2026-05-20) as models cooled.^2,3 EIA's longer-range Annual Energy Outlook 2026, published on Tuesday (2026-05-19), projects electricity consumed by data center servers will keep rising across the commercial building stock through 2050, with standalone facilities driving most of that growth.⁵ That long-run demand is one reason the agency expects gas-fired generation to set fresh records before the decade is out, even though the 2026 path there runs through a summer that so far looks ordinary.⁵ China's thermal generation, mostly coal-fired, rose 1.5% in 2024 to 6.34 trillion kWh, official data showed on Friday (2026-05-15), defying calls that coal output had peaked.⁴ Growth was the slowest in nine years outside the pandemic, and December output alone fell 2.6% year on year.⁴ For 2025, Greenpeace analysts said renewable power could cover all of China's new demand growth.⁴ The read-through for global LNG is direct: if Asian power demand for gas flattens on that renewables build, more spot cargoes could rotate toward Europe and weigh on TTF.⁴ Signal readings across ERCOT and MISO real-time markets lean bearish, consistent with a mild shoulder season sliding into a slow summer.² A smaller camp stays bullish on Henry Hub front-month, betting demand firms. For a gas-weighted producer, the test is whether July or August cooling load arrives fast enough to bite into the supply overhang.³ Permian-associated output is the engine. EIA expects the Permian to produce 29.2 Bcf/d in 2026, 6% more than 2025, then to grow 10% in 2027 as pipeline constraints ease.¹ Haynesville, a gas-dominant play, is forecast to expand 6% this year and 8% next.¹ None of that incremental supply is being soaked up by power burn right now.¹ The next read comes from EIA's storage balances. If injections keep building faster than power burn can absorb the new supply, the record-demand case for 2027 looks more like a forward bet than a present trade, and Henry Hub stays capped until cooling load delivers the catalyst the spring strip had priced in.⁶
