Solar helps European grids withstand heatwave stress, Ember says

Ember's analysis of June-July 2026 heatwaves focuses on how extreme temperatures and drought affected European power systems in several hard-hit countries. Solar output helped cover daytime demand during periods when cooling load was elevated and some thermal generation faced weather-related constraints. The episode reinforces the need to pair high solar penetration with storage, demand flexibility, and grid planning that can handle more frequent climate-driven stress events.
