Energy System Resilience
…Association country, on energy system resilience, publishing a 10-point plan ahead of the 2024-2025 winter, along with a 2025-2026 update and a roadmap for decentralising Ukraine's power system. This has provided Ukraine with critical assistance, while also offering invaluable real-world lessons that can inform resilience planning for IEA Member countries and beyond. Industry from Europe and other regions is already collaborating with the Ukrainian private sector and learning from practices forged under extreme conditions as they provide support. This report distils key lessons from Ukraine's experience that can inform energy system resilience efforts worldwide.

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…

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.

IEA Support to Accelerating Renewable Energy Permitting (ARPE)
…providing multiple applicable insights for policy makers in focus countries and beyond.This webpage contains a summary of the main findings resulting from the ARPE action, as well as the summary reports containing the main findings of each workshop. It provides examples of solutions and can inform policy-making, as well as all other stakeholders engaged in renewable energy project development.The project was funded by the European Union (EU) via the Technical Support Instrument, which is managed by the Reform and Investment Task Force (SG REFORM) of the European Commission. The project is implemented by the International Energy Agency (IEA…

Policy options to accelerate distributed solar PV in Ukraine
…energy 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…

Unlocking Ukraine’s Hydrogen Opportunity: A Roadmap
…from the war has been extensive, with reconstruction costs previously estimated by the World Bank at more than USD 0.5 trillion – three times Ukraine’s GDP.Reconstruction offers an opportunity to build back better. In the energy system, this means strengthening energy security and reducing GHG emissions. The use of low-emissions hydrogen in industrial applications can provide the dual benefit of lowering GHG emissions and supporting the development of an export-oriented industrial base that can help to restore the fiscal balance. This is a long-term opportunity that will not happen overnight, but efforts need to start…

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…
