As Europe approaches the winter season, ENTSO-E releases today its Winter Outlook 2025–2026. The report forecasts an overall favourable adequacy situation across the continent, with European Transmission System Operators (TSOs) continuing to monitor the situation throughout the winter period.  

The report finds that some risks to electricity supply may occur in Cyprus, Ireland, and Malta.  In Finland, Estonia and Lithuania, minor risks are forecasted in the event of exceptionally adverse operational conditions combined with cold weather and a high number of unplanned outages. Targeted non-market resources are planned to mitigate the risks in Ireland and Malta. 

European power system trends since winter 2024–2025 show a decrease in conventional general and an increase in renewable energy sources (RES). Planned outages and demand patterns are comparable to last winter while hydro reservoir levels are higher than in previous years. These combined factors anticipate favourable adequacy conditions.  

Since March 2022, Ukraine and Moldova have been synchronised with the Continental European power system. The situation in Ukraine remains uncertain due to attacks on energy infrastructure. European TSOs continue to support the coordinated effort to maintain grid stability in Ukraine. 

The Winter Outlook report is accompanied by a retrospect of last summer.
