France EUR 9, Germany EUR 103: record spread
European Energy Markets- What is the France-Germany day-ahead power spread and why does it matter?
- The France-Germany day-ahead spread is the difference between French and German day-ahead electricity clearing prices, published by EPEX SPOT. It measures the energy cost divergence between France's nuclear-dominated grid and Germany's gas-and-carbon stack. On 3 June 2026 it hit a series record of EUR 93.68/MWh, meaning French power was EUR 8.96 while German power cleared at EUR 102.64.Source: EVREF:3878
- Why did the France-Germany power spread hit a record high in June 2026?
- A late-May heatwave pushed a midday solar surge into an already nuclear-long French grid, collapsing French day-ahead to EUR 8.96/MWh. Germany, dispatching on gas and carbon, cleared at EUR 102.64. The combination of maximum French nuclear surplus and Germany's EUR 75/t carbon-set clearing price produced the record EUR 93.68/MWh gap.Source: EVREF:3878
- How does the Flamanville-3 overhaul affect the France-Germany power spread?
- Flamanville-3 is a 1,650 MW EPR reactor entering a one-year overhaul from September 2026. Removing 1.6 GW from France's nuclear fleet at heating-season onset compresses the French nuclear surplus that has been driving French clearing prices down and the spread up. Analysts expect the spread to narrow as the surplus withdraws into winter when German gas demand rises.Source: EVREF:3390
- What does the France-Germany power spread mean for industrial electricity prices?
- Since January 2026, the VNU mechanism passes near-spot French power prices directly to French industrial consumers. When the spread is EUR 93/MWh, a French manufacturer buying power at EUR 9 faces a German competitor paying EUR 103 for the same delivery. That gap compounds into a structural cost advantage for French energy-intensive industry over its German counterparts.Source: EVREF:3878
- What is the role of carbon prices in the France-Germany power spread?
- Germany's day-ahead clearing price is set by combined-cycle gas turbines (CCGTs) running on gas plus carbon allowances. With EUA carbon at around EUR 75-78/tonne and TTF gas near EUR 47-49, the German CCGT marginal cost sits near EUR 100-130/MWh. That sets the upper end of the spread; the lower end is the French nuclear clearing price, which is suppressed by surplus nuclear output.Source: EVREF:3787
Background
The France-Germany day-ahead power spread is the differential between the day-ahead electricity clearing prices in France and Germany, published by EPEX SPOT each afternoon for next-day delivery. Because France's grid is structurally dominated by nuclear baseload and Germany's by gas-fired and renewable generation, the two clearing prices reflect fundamentally different merit orders. French prices track nuclear output and interconnector capacity; German prices track gas costs, carbon (EUA) prices, and the moment-to-moment balance between renewables and thermal dispatch. The spread is a live signal of how much cheaper or more expensive French power is relative to Germany, and how FAR cross-border interconnectors can arbitrage the gap.
The spread hit a series-record EUR 93.68/MWh on 3 June 2026 when a late-May heatwave pushed a midday solar surge into a nuclear-long French grid, collapsing French day-ahead to EUR 8.96/MWh while Germany cleared at EUR 102.64/MWh on its gas-and-carbon CCGT stack . Earlier highs in the same series include EUR 55.75/MWh on 28 April 2026 and EUR 46.58/MWh on 21 May ; a compression to EUR 23.68/MWh on 12 May showed the spread is driven by weather and thermal dispatch, not a fixed structural gap . Three forces primarily move the spread: (1) French nuclear output, particularly the output of Flamanville-3 and any unplanned outages; (2) the German carbon-stack clearing price, which tracks EUA at around EUR 75-78/t and TTF gas; and (3) interconnector capacity between France and Germany, which when saturated prevents arbitrage from compressing the spread regardless of the price difference.
The spread has industrial as well as trading significance. Since the VNU mechanism replaced ARENH on 1 January 2026, French industrial consumers receive power at near-spot prices linked to EDF's nuclear output. When the spread is EUR 93/MWh, a French smelter buying at EUR 9 faces a German competitor paying EUR 103 — a real-time competitiveness divergence that accumulates into structural cost differences for energy-intensive manufacturing. The spread is expected to narrow in autumn 2026 when Flamanville-3 enters a one-year overhaul removing 1.6 GW from the French nuclear fleet at heating-season onset, compressing the surplus that has suppressed French clearing through Q1-Q2.
