Power markets moved against the gas signal
Electricity prices rose across most major European markets last week even though TTF gas futures fell to their lowest settlement level since February, according to analysis from AleaSoft Energy Forecasting reported by

. The divergence is a useful reminder that wholesale electricity pricing is shaped by more than fuel benchmarks alone, particularly in a continent where weather-driven renewable output now has a growing influence on market outcomes.AleaSoft found that weekly average electricity prices increased in the Belgian, British, Dutch, French, German, Italian, Nordic, Portuguese and Spanish markets compared with the previous week. In most of the markets analyzed, average prices ended above €95 per megawatt-hour.
The main exceptions were France, Portugal and Spain, where averages were considerably lower at €70.93/MWh, €50.73/MWh and €50.38/MWh, respectively. Those three countries share a notable feature from the same week: each set a national record for solar power production on a day in April.
Solar strength helped cap prices in France, Portugal and Spain
On April 17, Spain generated 213 gigawatt-hours of solar electricity, while France reached 145 GWh and Portugal recorded 26 GWh, all cited as new April daily records. That surge in solar output appears to have softened wholesale prices even as average prices elsewhere in Europe moved higher.
The contrast is telling. Falling gas prices would ordinarily be expected to ease pressure across power markets, especially in systems where gas-fired plants often set the marginal price. But when renewable output differs sharply by region, local generation conditions can overwhelm the broader fuel trend. In this case, stronger solar generation in parts of southwestern Europe helped pull market averages well below those seen in many neighboring countries.
The implication is not that gas no longer matters. Rather, it is that the pricing relationship is becoming more conditional. As solar penetration rises, the market impact of sunny days can become large enough to materially separate national outcomes even within a tightly watched regional energy economy.
A changing market logic in Europe
Europe’s power market has spent years operating under the shadow of gas volatility. Since gas often remains the balancing fuel that clears supply and demand, wholesale electricity prices can remain highly sensitive to changes in gas futures. Yet last week’s movement highlights how that relationship is being reshaped by the growth of renewables.
When gas falls but electricity still rises in many markets, the result points to other forces in play, whether those are demand patterns, interconnection constraints, weather effects on renewable generation or shifts in broader supply conditions. The source material does not attempt to attribute every causal factor. What it does show clearly is that lower gas alone was not enough to stop week-on-week electricity price increases across much of the region.
At the same time, solar’s role is becoming easier to quantify. France, Portugal and Spain did not simply experience strong output. They set records for April daily solar generation, and they were also the markets where weekly average power prices stayed well below the levels seen across much of Europe.
Why the numbers matter
For policymakers and investors, these figures reinforce two realities at once. First, Europe’s electricity markets remain exposed to conventional energy benchmarks, and price relief in one input does not automatically translate into lower wholesale power costs. Second, high renewable output can create significant local price advantages, especially when solar generation reaches record levels.
That combination makes forecasting more complex but also more revealing. It suggests that system design, grid integration and renewable buildout are becoming increasingly important in determining whether falling fuel prices actually benefit power consumers. It is no longer enough to watch gas in isolation.
For developers, the record solar days in Spain, France and Portugal also illustrate how quickly renewable production can alter market conditions in spring periods with favorable irradiation. For grid operators and traders, such swings heighten the importance of managing variability and anticipating when abundant daytime generation will pull prices away from wider regional patterns.
The bigger energy transition signal
The week’s price action offers a compact picture of the transition now underway in European electricity. Fossil fuel prices still matter, but they no longer explain everything. Renewable generation is not just an environmental metric or a capacity statistic. It is increasingly a market-shaping force with direct effects on wholesale outcomes.
That does not mean the transition has resolved Europe’s affordability challenge. Average prices above €95/MWh in many major markets show the region is still operating under substantial cost pressure. But the lower averages in France, Portugal and Spain show where part of the answer may lie: stronger renewable output, especially when paired with the system conditions needed to turn that output into sustained market relief.
Last week’s data therefore tell two stories at once. Europe is still vulnerable to complex pricing pressures. And in a growing number of cases, solar is becoming powerful enough to bend those pressures in visible, measurable ways.
