Ukraine’s Energy Security
…importance. While Ukraine made strong strides in rebuilding and strengthening the resilience of its energy system this past spring and summer, the situation remains fragile, and the risk of huge disruptions and widespread destabilisation remains – particularly as Russia expands the scope and sophistication of its attacks.This analysis builds on the IEA’s September 2024 report, Ukraine’s Energy Security and the Coming Winter. It provides an update on the latest developments through October 2025 and proposes key actions that Ukraine and its partners can take to address urgent energy security vulnerabilities this winter and bolster longer-term energy resilience…

Energy System Resilience
Lessons learned from Ukraine Ensuring energy security encompasses both long-term and short-term dimensions. The long-term dimension involves securing sufficient infrastructure investment and diverse supply sources. The short-term dimension – resilience – focuses on systems’ ability to cope with events exceeding standard planning conditions. Since Russia’s full-scale invasion in 2022, Ukraine has worked to protect its energy sector and to increase its ability to withstand and rapidly recover from Russia’s attacks on its energy infrastructure. The report explores the lessons that Ukraine has been learning as it works to bolster system resilience and identifies measures that…

Powering Ireland’s Energy Future
…this transition, supported by a detailed security study on the electricity supply mix.The analysis sets out five pillars for policy action: Establishing a cross-sectoral energy security strategy for the 2030s; delivering the enabling infrastructure to accommodate the growth of electricity demand and supply; accelerating the delivery of generation capacity, storage and demand-side flexibility; enabling secure system operation under high renewable penetration; advancing workforce skills, strengthening partnerships and facilitating electrification. Ireland can build on its progress in power system transformation to set an example of secure integration of large shares of variable renewable generation while safeguarding energy security.

Unlocking Ukraine’s Hydrogen Opportunity: A Roadmap
Ukraine’s energy sector has been severely affected by the Russian Federation’s full-scale invasion. The power sector went from having a large capacity surplus before the war to a power deficit in 2024 due to Russia’s attacks. This has focused attention on energy security and restoring the reliability of supply. Hydrogen demand from conventional applications in refining and ammonia has also plunged, falling 80%, with most of these assets in southern Ukraine, where the frontline and occupied areas are located. Overall economic damage from the war has been extensive, with reconstruction costs previously estimated by the World…

Policy options to accelerate distributed solar PV in Ukraine
…storage deployment will support Ukraine in establishing energy security.In the year following the Russian Federation’s full-scale invasion of Ukraine in 2022, available dispatchable power generation capacity halved from roughly 38 GW to 19 GW. After severe attacks in spring 2024, capacity declined further, down to 12 GW. Towards the end of 2024 Ukraine was able to restore 3 GW and has worked to restore and add additional capacity throughout 2025, despite ongoing attacks.Distributed solar PV has played a key role, providing cost effective and rapid increases in electricity generation capacity, contributing to system resilience and overall energy security…

Scaling Up Demand Flexibility
From peak management to efficient system operation This report has been developed as part of the International Energy Agency (IEA) Digital Demand-Driven Electricity Networks (3DEN) initiative to examine the growing importance of demand flexibility in electricity systems amid rising demand, increased renewable energy integration and the electrification of power systems. Case studies in chronological order to examine the changing role of demand flexibility over time from South Africa (2025), Thailand (2030) and Ireland (2035) demonstrate how demand flexibility improves reliability, reduces costs, supports renewables integration and manages network constraints. To realise these benefits, the report emphasises the role for…

IEA Support to Accelerating Renewable Energy Permitting (ARPE)
…for renewable energy in the overall energy mix to 42.5% (with the ambition of 45%) – up from 40% in the 2021 proposal. Achieving this will require more than 1 200 gigawatts (GW) of installed cumulative renewable power capacity by 2030, almost double that of 2023.The key barrier to rapid renewables deployment in many EU Member states is lengthy and complex administrative procedures related to project permitting. In May 2022, the European Commission released recommendations on permitting, including on identification of renewable acceleration areas (RAAs) where shortened and simplified permitting can be applied.In November 2023, the revised Renewable Energy Directive…
