German day-ahead power cleared EUR 156/MWh on 16 July, up from EUR 126 two days earlier, as cooling demand under the heat dome dragged the clean spark spread from negative into positive.

Key takeaway

A demand-driven spark spread turned Germany's CCGTs profitable, a margin a cooler week would knock out.

Germany day-ahead power cleared an average EUR 126/MWh on 14 July, EUR 132 on 15 July and EUR 156 on 16 July, climbing on cooling demand as the heat dome held ¹. Day-ahead is the price for next-day delivery; the clean spark spread is what a gas-fired CCGT earns after paying for its gas and its carbon. Run these clears through the standard 49.13% efficiency and 0.365 tCO2/MWh convention, against TTF near EUR 55 and EUA carbon near EUR 80, and the spread swings from roughly negative on 14 July to positive by 16 July.

German combined-cycle plants clear because the heat needs the megawatts, and the margin turning positive is a by-product of power outrunning its inputs rather than any softening in gas. That distinction is the whole trade: a spark spread that widens on power strength behaves differently from one that widens on cheap fuel, because it collapses the moment the heat breaks.

This eases rather than reverses the squeeze the desk logged on 9 July, when gas and power rose together and compressed the same spread . Then the pressure came from the fuel side; now it comes from demand. The CCGT stack is back in the money, but on a footing that a cooler week would knock straight out again.

Deep Analysis

In plain English

Gas-fired power stations in Germany make money on the gap between what they pay for gas and carbon permits and what they earn selling electricity. That gap, called the clean spark spread, had been slim or negative for weeks. This week electricity prices jumped because of the heat wave (people running air conditioning), while gas and carbon costs did not rise as much, so gas power plants suddenly became profitable to run again. It is less about gas getting cheaper and more about electricity getting more expensive faster than its ingredients did.

Deep Analysis

Root Causes

Germany's clean spark spread flips sign whenever day-ahead power climbs faster than its two input costs, gas (TTF) and carbon (EUA), move together. This window that happened because cooling demand pulled German day-ahead from EUR 126 to EUR 156/MWh across three sessions while TTF firmed only modestly and EUA actually eased back under EUR 81 (see the carbon event in this briefing), leaving the power side of the equation to do almost all the work.

The structural precondition is thin renewable output: when wind generation is low during a heat dome, as it has been through this window, German CCGT plant sets the marginal clearing price directly, so any demand spike shows up in the power price with little dilution from cheaper generation displacing it.

What could happen next?

Consequence
A positive clean spark spread gives German CCGT operators an incentive to run harder into the remaining heat window, which in turn supports gas demand even as storage injection slows elsewhere.

Causes and effects

Caused by

Two shocks squeeze the spark, not FR-DE

Continues the 9 July gas-and-power squeeze on Germany's clean spark spread, which now turns positive rather than negative.

This Event

German power climbs to EUR 156, spark flips

The spark margin turned positive because power outran its own fuel and carbon costs, not because gas got cheaper.

Led to

German gas plants priced out of merit

The positive clean spark spread recorded on 16 July inverted to negative by 20 July as gas and carbon costs outpaced power revenue.

Spark stays negative, French edge erodes

German gas plants back in profit

16 July was the prior occasion the spark turned positive, on heat demand under a heat dome rather than on this wind collapse; this is the third such inversion-to-recovery cycle.

Different Perspectives

China's Ministry of Commerce

Spokesperson He Yadong said on 16 July that Beijing and the Netherlands should let firms settle the Nexperia dispute through consultation, after a Dutch ministerial visit to Beijing. The conciliatory tone contrasts with the confrontational US trade response to the same fortnight's DMA enforcement.

Samsung Electronics

Samsung entered talks reported 22 July to invest up to €1 billion in Mistral AI, part of a round valuing the French lab at roughly €20 billion alongside EQT, Novo Holdings and Santander. The Korean conglomerate, not an EU financing instrument, is positioned to anchor Europe's flagship AI lab.

Poland (Tusk government)

Donald Tusk's government proposed a mandatory sovereignty test on 21 July for state technology contracts above 5 million zloty, scoring bids on AI model-weight rights and vendor lock-in rather than waiting for an EU-wide procurement rule. The threshold targets a 20-30 per cent domestic-alternative share.

United States administration

Donald Trump ordered a Section 301 investigation into EU digital-enforcement practices on 24 July, a day after USTR's Jamieson Greer said the Google fine created massive uncertainty for US exports, noting Google's cumulative EU fines already exceed 2 per cent of the bloc's budget.

Ecosia

Ecosia said the 16 July FRAND ranking-data order would take it from answering two-thirds of queries to all of them once the obligation activates in January 2027. The Berlin-based challenger has not called the enforcement package adequate, only workable if Google complies rather than appeals.

European Commission

Teresa Ribera and Henna Virkkunen announced the €890m fine on 23 July, saying products should succeed on merit, not platform ownership; four days earlier a separate Article 6(7) order compelled Android interoperability. The Commission expects both to hold on appeal after the Court of Justice upheld its earlier €4.1bn Android fine on 2 July.
