German and French day-ahead rose together over 6-10 July, keeping the FR-DE spread compressed while a firmer TTF and flat EUA at EUR 78.95 squeezed the clean spark spread instead.

Key takeaway

Two shocks at once compressed the FR-DE spread and squeezed the clean spark spread instead.

German day-ahead baseload cleared 93.78, 71.66, 100.73, 124.58 and 123.04 EUR/MWh across 6 to 10 July, while France cleared 86.97, 89.30, 94.32, 110.02 and 118.68 ¹². Both legs rose together, so the DE-minus-FR spread swung only from -17.64 to +14.56, France the dearer leg on 7 July, a world away from the EUR 71.50 gap the 30 June heat opened when German wind collapsed alone . That spread had already compressed towards EUR 18-26 by 5 July .

The clean spark spread carries this squeeze, not the cross-border one. TTF firmed on the prompt with no matching lift in CCGT running margin, while EUA carbon settled 78.95 EUR/tCO2 on 9 July, roughly flat on the day 3 . The same margin pressure reached EUR 74 as recently as 30 June . Flat carbon isolates the move as fuel-and-power rather than a carbon-cost shift. Settled baseload stayed moderate at 100 to 125 EUR/MWh, well below the 200-plus evening peaks forecasters flagged, so the pressure reads as a margin squeeze on spark economics, not a power-price explosion.

Deep Analysis

In plain English

A spark spread is the profit margin a gas power plant makes: the electricity price it sells at, minus the cost of the gas it burns to make that electricity. When gas prices rise faster than electricity prices, that margin gets squeezed. This week, German and French electricity prices rose together rather than one country becoming much more expensive than the other, which is what usually happens when only one side has a problem like low wind. Instead, both countries are paying more for the gas that increasingly sets their electricity price, a Europe-wide cost pressure rather than a one-country weather problem.

Deep Analysis

Root Causes

Germany's marginal price is set by its gas-fired plants whenever wind is short, so a firming TTF prompt raises the clearing price directly. Because carbon has not moved in the same window, the squeeze lands entirely on the CCGT operating margin rather than being partly offset by cheaper emissions costs.

France normally provides a cheaper nuclear-led floor that decouples its price from Germany's gas-driven one, which is why the two countries usually diverge under stress; this window's parallel rise instead suggests France's own thermal and import-exposed margin is being squeezed by the same TTF move, not by a separate French-specific constraint.

What could happen next?

Consequence
CCGT operators in both Germany and France see thinner margins on new generation even as headline power prices rise, since fuel costs are keeping pace with the power-price increase.
Meaning
A squeeze that hits both countries together, rather than one, marks a fuel-cost-driven episode distinct from the wind-dependent divergence of 30 June.

United States×2

Primary parallel: The 30 June heat episode blew out the FR-DE spread to EUR 71.50 rather than compressing Germany's spark spread, because the driver then was a German-side wind collapse that isolated Germany's price rise while France's nuclear-heavy baseload stayed cheap .

Counter-parallel: This window's mechanism is structurally different: both countries' baseload rose together, Germany from 93.78 to 123.04 and France from 86.97 to 118.68 over 6-10 July, because a firming fuel cost lifts the gas-fired margin in both markets equally, rather than one country losing a generation source the other still has.

Consensus view: EUA settled at EUR 78.95 on 9 July, down slightly day-on-day even as TTF firmed 13% over the same window, an institutional read that the German and French baseload rise is being driven by fuel cost and demand together rather than by carbon.

Counter-view: The same demand pressure that lifted both countries' baseload together, a second heat dome forecast to peak 9-14 July, could equally be read as the primary driver, with TTF's firming a secondary amplifier: German and French prices began moving together before TTF's climb reached its full 13%.

Key tension: Whether the German clean spark spread compression reflects a genuine fuel-cost squeeze that persists once the heat dome passes, or a temporary demand spike that unwinds as quickly as the 30 June episode did by 4-5 July .

Different Perspectives

Slovakia

Slovakia says it dropped its hold-out on the 21st sanctions package only after Ursula von der Leyen personally signed written gas-price and supply guarantees. The Council of the European Union's own 17,238-character release on the package names neither Slovakia nor any guarantee, leaving Bratislava's account unconfirmed by the institutional record.

EU regulator on capacity mechanisms

Brussels is watching Germany's StromVKG first 4.5 GW capacity auction move toward its 8 September bid deadline without a resolved state-aid clearance for the 9 GW 2026 programme's gas-plant subsidies. A negative spark spread this deep on cheap gas strengthens the case for subsidised dispatchable capacity, the same case still awaiting a state-aid ruling.

French power exporters

French day-ahead cleared EUR 41.13/MWh on Sunday 26 July, EUR 43.09 below Germany, on wind more than doubling and a demand trough, not on any nuclear recovery. The desk expects the discount to hold only as long as French wind and weekend demand repeat, not as a durable nuclear-cost advantage.

European gas storage operator

A storage operator stopped bidding for prompt TTF cargoes on 21 July, reading the strike-halt unwind as the start of a fuel-side correction rather than a floor. It expects the gap between prompt and forward gas to keep narrowing as the war premium continues leaving the curve.

German gas-fired power fleet

German gas-fired plants cut output from 4.37 GW to 2.85 GW between 24 and 27 July, even as TTF fell 8 per cent, because below roughly minus EUR 40/MWh the fuel price stopped deciding dispatch. The fleet expects no relief until wind eases or StromVKG's first 4.5 GW auction adds capacity.

French industrial power consumers

France's day-ahead discount to Germany has nearly closed as TTF and EUA rise together on both sides of the border, eroding the arbitrage French industry relied on through the summer. A standing negative spark removes the German demand buffer that kept that spread wide.
