European Power Prices Jump as Heatwave Forces More Nuclear Curtailments

Moderate confidence (75%)
Risk direction: volatile · Impact: HIGH
Executive summary
In the next 24 hours, worsening European heatwave conditions and associated nuclear plant shutdowns or deratings will trigger higher intraday volatility and upward pressure in key power markets, especially France and Germany. Gas-fired generation will ramp up to compensate, boosting demand for pipeline gas and LNG at precisely the moment Gulf risks are stressing global energy supply chains. This will intensify margin pressure on energy‑intensive industries and could force spot market intervention by governments or utilities. Confirmation would be further nuclear output reductions, day-ahead power price spikes, and rising TTF gas contracts; denial would require rapid cooling or regulatory waivers allowing higher operating temperatures.
Key indicators we're watching
