European power prices pop as wind stalls, pushing evening peaks above €600

What happened

Power markets tightened fast on Monday after wind generation slumped, lifting some evening quarter-hour slots beyond €600 per megawatt-hour. For Monday delivery, France's day-ahead price settled at €334.12 per megawatt-hour on the Epex Spot SE platform, reaching a level not seen since December 2022, while Germany's day-ahead cleared at €345.64.

The UK grid operator warned of tight conditions Monday morning and sought extra supply from the market, then withdrew the alert. ENTSO-E data show gas-fired generation in Germany at its highest level since January.

Why prices jumped

Forecasters expect a slow-moving system of still, overcast weather to suppress renewable output through Wednesday across some of Europe's biggest power markets. The lull looks most acute in Germany, the UK and the Benelux countries.

Natural gas prices are elevated this year, and gas-fired units frequently determine the market-clearing price for electricity. That bites during cold, windless stretches known in German as Dunkelflaute, when renewables fade and pricier fossil-fuel units fill the gap. "These kind of high prices can not only be explained by elevated gas prices but show there is a certain scarcity in the system," said Kpler energy analyst Alessandro Armenia, who said such bouts will probably return at least until mid-January.

The broader squeeze

Cooling weather could add more strain. MetDesk meteorologist Ben Davis expects temperatures to run 1C-3C below normal this week, a setup that lifts heating demand. Energy Aspects also flags below-average hydro after a dry year and maintenance that is limiting French nuclear capacity.

The pressure is visible in futures. On EEX, buyers and sellers are transacting December German and French power around €200 per megawatt-hour, more than double the level a year ago. In plain English: if periods of low wind and solar become more frequent this winter, price spikes are more likely to show up again.

What it means for investors

Day-ahead prices whip with weather and fuel, but the signal for portfolios is forward pricing near €200 as supply remains constrained and repeats of these conditions are probable at least until mid-January. Expect choppier earnings lines for energy intensive industries and more optionality value for utilities with flexible gas or hydro, while traders lean into volatility.
