A persistent European heatwave has lifted summer electricity demand, reversing the downtrend since the 2022 energy crisis. ENTSO-E data show average French demand in April–mid July reached the highest level for that period since 2022, marking the first YoY increase in that window after three consecutive years of decline. EEX data show French next‑month delivery power prices have risen roughly fourfold since late April, topping €80/MWh by end‑June and remaining elevated month‑to‑date. Power futures plunged in spring on strong solar generation and weak seasonal demand, but expectations of sustained high temperatures have quickly reversed the market.(金十数据)
