Brussels, 13 November 2026 – ENTSO-E has published its Winter Outlook 2026–2027, assessing whether Europe has sufficient electricity resources to meet demand throughout the coming winter. The assessment finds an overall favourable adequacy situation across Europe, while identifying specific risks in some areas, particularly for systems with limited or no interconnection to the continental European network.
Compared to 2025 winter, Europe has significantly more renewable generation and battery storage capacity, alongside a further reduction in conventional thermal capacity. Installed renewable (RES) capacity has increased by roughly 134 GW (+16%), mainly from rooftop, industrial, and utility-scale solar PV. Battery storage capacity has more than doubled to 38 GW, while hard coal and lignite capacity has decreased by nearly 6 GW. Planned outages and demand are comparable to last winter, while hydro reservoir levels are lower than average overall.
Some electricity supply risks have been identified in Cyprus, which has no interconnection to the European continental network. While some of these risks are identified under normal market conditions in Malta and Ireland, dedicated non-market resources significantly alleviate these risks. Traces of adequacy risk are also visible in the East of Denmark (bidding zone DK2), Finland, and Northern Ireland.
Cross-border cooperation and close coordination at European, regional, and national levels will be essential to maintain the balance between supply and demand this winter. Actual conditions may be tighter in some areas if demand, weather, generation availability or cross-border exchanges differ from the assumptions used. TSOs will continue to monitor adequacy conditions closely throughout the winter.
ENTSO-E’s Winter Outlook report demonstrates the added value of a pan-European scope for adequacy analysis, while complementing adequacy assessments carried out on a national and regional level. A wide range of processes are in place to address these risks. These range from weekly operational coordination between TSOs and regional coordination centres all the way to the Risk Preparedness Plans developed by each member state.
