European Power and Carbon: EUA, Day-Ahead Prices — 2026-10-02
European electricity markets surged in the final week of September as wind generation fell sharply across the continent, driving Nordic prices up 35% and pushing wholesale costs to multi-year highs. Energy inflation is re-emerging as a policy concern for the ECB, while carbon prices remain volatile amid competing pressures from gas market swings and coal-switching dynamics.
European Power and Carbon: EUA, Day-Ahead Prices — 2026-10-02
Top developments
Nordic electricity prices spike 35% as wind generation collapses
In the fourth week of September, Nordic day-ahead prices jumped 35% week-on-week, the strongest gain across major European markets. Wind output fell sharply across the region, tightening supply. Great Britain followed with a 31% price increase, while most continental European markets posted double-digit rises. Italy was the only major market to post declines. This marks the opening act of seasonal volatility typical of autumn transitions when renewable curtailment wanes and thermal generation demand recovers.
Energy inflation re-enters ECB's policy calculus
Europe is experiencing a fresh energy-driven inflation shock, forcing the ECB into a difficult policy balancing act. Aggressive rate hikes risk slowing growth while insufficient tightening could allow energy prices to spread into broader consumer and wage inflation. This mirrors the 2022 energy crisis but operates through different transmission channels—this time emphasizing diesel fuel constraints and chokepoints rather than pure gas supply shocks. Policymakers face the prospect of energy costs compounding economic headwinds into late 2026.
European wholesale power climbs amid seasonal demand pivot
Prestige Business Solutions' 28 September market report confirmed that wholesale power prices across major EU hubs climbed during the final stretch of the month as seasonal cooling demand faded and heating demand began its autumn ramp. Day-ahead contract prices tightened in response to falling renewable output and early heating preparations. Market participants are pricing in a colder-than-normal winter scenario and increased reliance on gas-fired generation to meet peak loads.
Fraunhofer ISE releases battery storage simulator impacting EPEX pricing dynamics
Germany's Fraunhofer Institute for Solar Energy Systems (ISE) published a new, freely accessible power-price simulator on its Energy-Charts platform that quantifies how battery storage stabilizes day-ahead market prices and reduces volatility at peak and trough hours. The simulator suggests that large-scale battery deployment could generate billion-euro savings to Germany's renewable-support (EEG) budget by smoothing intraday price spikes that currently reach hundreds of euros per MWh. Early results indicate that targeted storage deployment during evening peak periods (19:00–23:00 local time) could reduce price extremes by 15–25%. This development signals that market design improvements and storage flexibility are now entering mainstream European electricity policy discourse.
Local view
Poland (WNP.pl, Biznesinfo.pl, Enerad.pl): Polish energy market watchdogs report that coal prices have surged past 2,000 PLN/tonne by late September, pressuring thermal plant operators and driving TGE (Polish Power Exchange) forward prices toward 700 zł/MWh for Q4 2026 delivery. This reflects both the broader European gas-price squeeze and Poland's coal dependence. Medium-term competitive-market average prices in Q2 2026 stood at 427 zł/MWh, but autumn winter-contract fixings signal 60% seasonal premium entering heating season.
France (Optima Énergie, Kelwatt.fr): French power-market analysts reported (4 days ago) that electricity price volatility continues, driven by nuclear availability at EDF plants and external gas pricing. Day-ahead EPEX Spot quotes for France currently fluctuate in the €140–160/MWh range depending on wind and nuclear operational status. Summer price relief has fully reversed into autumn, with analysts now pricing in a "tight winter" scenario.
Germany (pv-magazine.de, photovoltaik.sh): German market commentary (2 weeks old but still relevant) noted that daytime price crashes caused by high solar influx contrast sharply with evening scarcity spikes when renewable output collapses. Heatmaps from Energy-Charts show evening peak hours (19:00–23:00) regularly hitting €300–700/MWh, while midday troughs drop to €50–100/MWh or occasionally negative. This intraday volatility is now the dominant trading dynamic at EPEX Spot.
Context & numbers
Price levels (week of 25 Sept – 1 Oct 2026):
- Nordic day-ahead (Nord Pool SE/NO): +35% week-on-week surge
- Great Britain (North Western Electricity Market): +31% week-on-week
- Germany/Austria (EPEX SPOT): +8–12% estimated (no headline index; driven by reduced solar + lower wind)
- France (EPEX SPOT): +6–9% estimated (improved nuclear availability partially offsetting gas-link)
- Poland (TGE RDN, spot auctions): €110–140/MWh range; Q4 2026 forward at ~€150–170/MWh
EUA Carbon Permits: No specific price fix data for the past 7 days was available in research results, but older reports (April–January 2026) indicate analysts expect significant volatility tied to gas prices, coal switching dynamics, and EU policy uncertainty around supply management. Historical context: coal-switching episodes and gas spikes drive EUA prices upward; policy intervention signals trigger sharp sell-offs.

On the radar
- Winter season opening (November–March 2026–27): Stakeholders are positioning for a "colder-than-average" scenario, with January 2027 hedging activity accelerating. Watch for late-October weather forecasts to anchor forward curves.
- EEX/EPEX auction calendar: End-of-month October auctions will reflect autumn demand ramp; monitor clearing prices for signals of sustained thermal dispatch.
- UK ETS (UKA) linkage: No specific recent price or linkage data available; EU market participants continue tracking whether UK carbon alignment will narrow or widen the EUA–UKA spread.
- Battery storage policy: Fraunhofer ISE's new simulator may influence upcoming German and EU grid-code revisions; watch for regulatory interest in mandatory storage requirements or subsidy reshaping.
