Germany's day-ahead power cleared EUR 195.00/MWh for 30 June delivery, a 2026 high for the date, as a summer heat surge ran straight into the year's weakest wind 1. The country logged its lowest wind generation of 2026 in week 26, the seven days to 28 June, a record rather than a passing lull 2.
Day-ahead power is the wholesale price set the afternoon before delivery, and on a high-renewable grid like Germany's it usually falls when the wind blows. Week 26 removed that cap. With wind near zero and cooling demand climbing, every incremental megawatt came from gas and coal units, whose marginal cost stacks fuel on carbon and sets the clearing price for the whole market.
With renewables gone from the stack, the clearing price tracked the thermal merit order straight up. The 17 June repricing had already driven German day-ahead 59% higher when wind briefly dropped out ; week 26 delivered the same condition in summer, with wind at a 2026 low compounding the heat load rather than relieving it. The print answers a season-long question: a EUR 195 day-ahead normally crowds injection out of the market, yet Germany kept filling storage through it, because at today's prompt gas the caverns and the turbines can both be served.
