2026 Energy Market Outlook: Three Pressures To Watch
The 2026 global energy market sits at the intersection of three pressures. Record renewable capacity additions suppress baseload prices in Europe and parts of Asia. LNG supply margins look tighter than expected after project delays on the US Gulf Coast and in Australia. A Northern Hemisphere summer that the NOAA seasonal outlook describes as likely above normal across Central Europe and the US Midwest adds heat-driven demand risk. Each factor feeds directly into short-term power and gas price formation.
The EIA projects US average retail electricity prices rising about 3–5% year-on-year in 2026. Higher natural gas input costs and grid-hardening capital recovery charges drive most of that increase. The IEA Electricity 2026 report shows EU futures prices as of 26 January 2026 averaging around USD 95/MWh for 2026. Asian spot LNG (JKM) prices continue to swing with seasonal demand from Japan and South Korea.
Model refresh cadence is the critical gap in every published baseline. Traders in Europe's weather-driven energy markets now use AI tools not just to predict temperatures and precipitation, but to forecast the forecast itself. They aim to anticipate revisions in the ECMWF two-week outlook before those revisions reprice risk in heating demand, renewable output, and system tightness.
EPT-2e, Jua's ensemble variant of the Earth Physics Transformer (EPT), is a general physics foundation model rather than a weather-specific model. It has been shown to surpass the ECMWF ENS mean on energy variables over the 0–240 h horizon at lower cost. That combination of ensemble skill and frequent refresh converts a static price outlook into a tradeable edge.

Are Natural Gas Prices Expected to Rise in 2026?
Given the supply-demand dynamics outlined above, the directional move across all three major gas benchmarks is upward, with strong regional differences in scale. Henry Hub is recovering from a multi-year trough. As noted in the outlook above, Henry Hub is expected to average $3.60/MMBtu in 2026 according to the EIA, supported by LNG export demand absorbing incremental Permian and Haynesville supply. TTF, the European Title Transfer Facility benchmark, trades structurally higher because of storage refill obligations and residual uncertainty around Russian pipeline supply. JKM, the Asian LNG spot benchmark, can trade at a premium to TTF during peak demand windows.
Weather acts as the primary swing factor on all three benchmarks. A colder-than-normal Q4 2026 in Europe, the scenario highlighted in the ECMWF seasonal outlook, would pull European storage from a projected 85% full at end-October to below 70% by January 2027. That draw would push TTF toward the upper bound and trigger LNG diversion from Asia. EPT-2e ensemble spreads on 2 m temperature over Central Europe at medium lead times are currently wider than ECMWF ENS. Those wider spreads indicate that the market is underpricing tail risk in the Q4 demand scenario.
The table below summarizes how EPT-2e's wider ensemble spreads highlight elevated tail risk across major gas benchmarks and European power markets, compared with baseline forecasts that may miss these extremes.
| Region / Benchmark | EIA / IEA Baseline (2026 Annual or H2 2026) | Upside Scenario (Weather-Driven) | EPT-2e Ensemble Delta vs. ECMWF ENS |
|---|---|---|---|
| Henry Hub (US natural gas) | $3.60/MMBtu | $4.50+/MMBtu (cold Q4 + LNG export surge) | wider spread on US temperature at short lead times |
| TTF (European natural gas) | Elevated relative to Henry Hub | €55+/MWh (dry autumn + cold Q4) | wider spread on EU wind/temp at short lead times |
| JKM (Asian LNG spot) | Varies with seasonal demand | $20+/MMBtu (cold snap + LNG diversion from Europe) | wider spread on East Asia temperature at short lead times |
| European wholesale power (day-ahead) | Around USD 95/MWh | €110+/MWh (low wind + low hydro + cold snap) | Surpasses ECMWF ENS mean on key metrics |

How Much Will Electricity Prices Go Up in 2026?
Electricity price paths in 2026–2027 diverge sharply by region. The interaction between renewable penetration and weather-driven generation variability drives that divergence. In the US, the EIA projects a 3–5% retail price increase nationally. That headline masks significant wholesale volatility in ERCOT (Texas) and MISO (Midwest), where wind penetration above 30% amplifies the price impact of forecast errors.
In Europe, the IEA's central scenario places German baseload at €70–€85/MWh for H2 2026. GB day-ahead prices track €5–€10/MWh above German levels because of interconnector constraints. In Asia, Japanese wholesale prices are projected at ¥15–¥20/kWh through 2026, with South Korean SMP at a similar level. Both markets remain sensitive to LNG spot price movements.
The weather-volatility channel is the dominant source of upside risk in all three regions. Jua's forecasts carry an estimated $1.5 million P&L impact per gigawatt annually in European energy markets, and that figure scales linearly across multi-GW portfolios. A 1 GW wind portfolio that gains four percentage points of forecast accuracy saves about €1.5 M/year under typical hedging and imbalance penalty structures. A 1 GW solar portfolio at the same accuracy gain saves about €3 M/year. At 10 GW of managed capacity, those numbers rise to €15 M and €30 M respectively.
The table below links those economics to concrete upside and downside price scenarios, tied to how far models diverge on key weather variables.
| Region | Central Scenario (H2 2026) | Upside (High Weather Volatility) | Downside (Mild Weather + High Renewables) |
|---|---|---|---|
| Germany (EPEX day-ahead) | €70–€85/MWh | €110+/MWh (Dunkelflaute + cold snap; high EPT-2e spread) | €40–€55/MWh (high wind + mild temps; low model divergence) |
| Great Britain (N2EX day-ahead) | €75–€95/MWh equivalent | €120+/MWh (low wind + interconnector constraint) | €45–€60/MWh (high offshore wind output) |
| US ERCOT (Texas wholesale) | $35–$55/MWh | $150+/MWh (heat dome + low wind; high EPT-2e spread) | $20–$30/MWh (mild summer + high wind) |
| Japan JEPX (spot) | ¥15–¥20/kWh | ¥25+/kWh (cold snap + LNG supply tightness) | ¥10–¥13/kWh (mild winter + high nuclear availability) |
Upside and downside scenarios are linked to EPT-2e ensemble spread width as a proxy for forecast uncertainty. Wide spreads, which signal high model divergence, correlate with elevated realized price volatility in historical backtests. All figures are forecasts, not trading recommendations.

What Is the Gas Market Outlook for 2026?
The structural backdrop for global gas markets in 2026–2027 is a supply-demand balance tighter than headline LNG capacity numbers suggest. The IEA highlights new LNG liquefaction capacity scheduled to come online globally through the late 2020s, mainly from US Gulf Coast projects such as Plaquemines LNG and Corpus Christi Stage 3, and from Qatar's North Field expansion. Project commissioning delays and ramp-up timelines limit effective incremental supply reaching spot markets in 2026. That constraint is not enough to loosen the TTF–JKM spread in a meaningful way.
Weather-driven demand risk acts as the main volatility amplifier. As discussed earlier, anticipating ECMWF outlook revisions before they reprice the market is now a direct source of alpha. As Jua founder Marvin Gabler has noted, "We realized early that this is about human nature more than mother nature. Traders need a system that understands how the physical world moves markets." EPT-2e's refresh cycle means that ensemble spread changes, a leading indicator of an impending ECMWF revision, are visible to Jua for Energy users before the next traditional NWP run lands.
The benchmarking data below compares the 25+ models available on the Jua platform across the metrics that matter for gas and power trading. These metrics are RMSE (root mean square error), CRPS (continuous ranked probability score), and operational lead time, which is the horizon at which a forecast is issued ahead of the valid time. EPT-2e is the ensemble variant of EPT-2. Hindcast refers to a retrospective forecast run against historical observations to validate model skill. The table highlights how EPT-2e combines stronger scores with faster refresh cycles.
| Model | RMSE vs. Observed (10 m wind, 10-day lead, normalized) | CRPS Skill Score vs. Climatology | Operational Refresh (runs/day) |
|---|---|---|---|
| EPT-2e (Jua ensemble, 10 members) | Beats ECMWF ENS mean on energy variables over 0–240 h | Beats ECMWF ENS mean on CRPS over 0–240 h | Multiple runs per day |
| ECMWF ENS (50 members) | Gold standard probabilistic NWP benchmark | Gold standard CRPS reference | 2×/day (main), 4×/day with supplementary |
| ECMWF HRES (deterministic) | 40-year NWP benchmark; EPT-2 outperforms on all lead times | N/A (deterministic, no probabilistic score) | 2×/day (main), 4×/day with supplementary |
| Microsoft Aurora | EPT-2 beats Aurora on 10 m and 100 m wind across 0–240 h | No productised ensemble equivalent published | Typically 4×/day (research cadence) |

Frequently Asked Questions
What supplies 80% of all energy in the world?
Fossil fuels, including oil, natural gas, and coal, collectively supply about 80% of global primary energy. That share has remained broadly stable for decades despite rapid renewable capacity additions. The IEA's World Energy Outlook places oil at roughly 30% of the total, coal at 26%, and natural gas at 23%, with nuclear, hydro, and modern renewables making up the remainder.
The persistence of fossil fuel dominance reflects the scale of existing infrastructure and the energy density of hydrocarbons. It also reflects the pace at which renewable capacity can displace thermal generation in baseload and dispatchable roles. Weather-driven variability in renewable output, especially wind and solar, means that gas-fired generation remains the primary balancing resource in most liberalized power markets. That role directly links atmospheric forecast accuracy to gas price formation.
What are gas prices expected to be in 2027?
The 2027 outlook for natural gas prices reflects two competing forces. Incremental LNG supply from US Gulf Coast and Qatari projects reaches full operational capacity. At the same time, structurally elevated demand from European industrial recovery and Asian power-sector gas burn persists. The IEA's central scenario for 2027 places TTF in the €35–€50/MWh range, with Henry Hub at $3.00–$4.20/MMBtu, assuming normal Northern Hemisphere winters in both 2026–2027 and 2027–2028.
A colder-than-normal winter in either year compresses European storage to levels that would push TTF toward €55–€65/MWh and trigger LNG diversion from Asia, lifting JKM to $18–$22/MMBtu. The downside scenario, which combines mild winters with full LNG ramp-up, would push TTF below €30/MWh and Henry Hub toward $2.50/MMBtu. Weather forecast accuracy at 10–15 day lead times has the greatest influence on which scenario materializes, because storage draw rates respond to temperature anomalies within days.
Are natural gas prices expected to go down?
The structural direction for natural gas prices through 2027 is sideways to modestly lower in the US and sideways to higher in Europe and Asia. In the US, domestic supply growth continues to outpace demand. In Europe and Asia, LNG import dependency and storage obligations create a firm price floor. Henry Hub is unlikely to return to the sub-$2.00/MMBtu levels seen in 2024 because LNG export demand absorbs incremental supply.
TTF is unlikely to fall below €25–€30/MWh given European storage refill costs and the residual risk premium on Russian supply uncertainty. The main downside scenario for both benchmarks combines above-normal temperatures in Q4 2026 and Q1 2027 with full LNG project ramp-up. The IEA assigns that scenario a 20–25% probability in its current risk distribution. Weather forecast accuracy, especially the ability to detect temperature anomalies at 10–15 day lead times before they are priced into the forward curve, determines whether traders can position for that scenario ahead of the market.
What is the outlook for global energy prices?
The global energy price outlook for 2026–2027 features regional divergence, elevated weather-driven volatility, and a shift in the sources of price risk. In power markets, rapid growth of wind and solar capacity suppresses average wholesale prices in Europe and parts of Asia. At the same time, it increases the frequency and magnitude of intraday price spikes driven by renewable generation shortfalls.
In gas markets, the LNG arbitrage mechanism tightens the correlation between Henry Hub, TTF, and JKM. A weather event in one region now propagates to global benchmarks within days. The net effect is a market environment where forecast accuracy at 5–15 day lead times has a larger P&L impact than at any previous point in the history of liberalized energy trading. As noted earlier, the economics of forecast accuracy are compelling, with multi-million-euro annual savings at the 1 GW scale that scale linearly across larger portfolios. Those economics justify significant investment in forecast infrastructure and explain why utilities, trading houses, and quant funds across five continents run Jua for Energy alongside their existing ECMWF subscriptions.
Conclusion: Turning Weather Volatility Into Trading Edge
The 2026–2027 global energy market will be defined by weather-driven volatility that legacy forecast infrastructure struggles to handle at the cadence modern trading requires. Henry Hub at $3.60/MMBtu, alongside elevated TTF and European wholesale power prices, forms the central scenario. Upside tails driven by cold snaps, Dunkelflaute events, and LNG supply delays remain wide enough to move portfolios by hundreds of millions of euros.
