A record of 45 TWH van Zonne energy was generated in the European Union in June, which helped to stabilize the electricity supply during the recent heat wave, according to Think Tank Ember.
Record volumes of solar energy helped to keep Europe’s electricity councils stable via a heat wave at the end of June and early July, according to a new report from London-based Energy Think Tank In the room.
The latest report from Ember, “Heat and power: Effects of the 2025 heat wave in Europe“Said the heat wave that Culminated between 28 June and 2 July raised the daily electricity demand by a maximum of 14% as the use of air conditioners rose.
This increase in demand, in combination with failure of thermal power plants and capacity reduction of nuclear power stations in different European countries, led to an increase in average daily energy prices from two to three. On the hottest days, electricity prices are more than € 400 ($ 468.53)/MWh.
Ember said that the challenges of the heat wave were partially compensated by the large quantities of solar energy produced. The European Union generated a record of 45 TWH of solar electricity in June, the highest monthly total to date, with different countries that also established new daily records for solar production.
In the peak days of the heat wave, Solar supplied electricity to 50 GW power alone, which generated more than a third of the land of the country. The report from Ember adds that Germany’s 14 GW battery storage and 10 GW pumped storage was then used to store some solar energy to use after sunset.
With heat waves that occur more often in Europe, Pwel Czyzak, the European program director of Ember, said that battery storage, interconnection, demand flexibility and dynamic rates should become an important part of grid planning and energy market design.
“The greatest chance is to save solar electricity to help the air conditioning well into the evening,” Czyzak added.
ENG also called for the use of smart electrification and usage rates for solar energy, because it could unlock consumer savings and relieve grid saling in times of stress, such as during heat waves.
