Energy System Resilience
…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 apply to a range of high-impact events – such as cyberattacks, physical attacks on infrastructure, extreme and severe weather, and unexpected infrastructure failures – and can in turn be adopted by policymakers and regulators around the world, taking into account national circumstances and following assessments of costs and risk.The International Energy Agency (IEA) has…

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…

Harnessing Energy Demand Restraint in Ukraine: A Roadmap
…the next five years. Summary brochure Discover Ukraine’s potential to improve its energy system through a comprehensive and integrated policy approach. Executive Summary Energy demand restraint is broadly defined to include policies and practices that help increase energy efficiency, reduce energy imports and improve operational flexibility and resilience throughout a country’s energy sector, particularly in the short term.Instituting demand restraint measures could considerably improve Ukraine’s energy system flexibility and resilience while also reducing energy imports, exerting downward pressure on energy prices and delivering a range of socioeconomic and environmental benefits. Ukraine’s energy policy framework recogni...

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…

Empowering Ukraine Through a Decentralised Electricity System
…a more resilient and modern power system by establishing a vision for decentralisation and by strengthening regulatory frameworks, coordination mechanisms, electricity markets and relevant technical requirements.The Ukrainian translation of this report is available in the "Related files" tab. Українську версію дорожньої карти можна знайти тут: “Related files”. Translation Rooftop PV Assessment Results While there are a few top-down estimates of the potential for rooftop PV in Ukraine, the general approach lacks the level of detail and reliability required for transformation strategies of the energy system. Hence, in context of the report Empowering Ukraine Through a Decentralised Electricity System…

Gas Resiliency Assessment of Japan 2016
…report contains several recommendations to improve the resiliency of Japan. In the energy system of Japan gas plays an important role, particularly so after the 2011 Great East Japan Earthquake, to compensate for the loss of nuclear power generation, which collapsed in 2014. Given its high import dependency, Japan has developed a robust natural gas security of supply policy.The challenges around security of gas supply are rapidly evolving. The traditional view of gas as a stand-alone fuel is becoming less relevant. With increasing gas market globalisation and greater interdependencies between gas and the rest of the energy system…

Japan Climate Resilience Policy Indicator
…foundation for climate change adaptation. It then completed a comprehensive assessment of climate change impacts and established a Climate Change Adaptation Plan. The Strategic Energy Plan (2018) and the Act for Establishing Energy Supply Resilience (June 2020) cover energy sector resilience to natural disasters. However, strategic planning to enhance climate change adaptation and resilience in the energy sector is still at an initial stage, partly because there has not been extensive research on the impact of climate change on energy systems. Climate hazard assessment TemperatureJapan’s average annual temperature rose 1.24°C per century since 1898. According to the Japan…

Japan 2021
…This IEA in-depth review comes timely, as it makes numerous recommendations that can be helpful in developing policies and measures to support achieving the new goal.Over the last decade, Japan made substantial progress in implementing its vision of an efficient, resilient and sustainable energy system. The gradual restart of nuclear power generation, expansion of renewable energy and energy efficiency gains have reduced the need for imported fossil fuels, and contributed to a continuous decline in greenhouse gas (GHG) emissions. These reached an historic peak in 2013, as fossil fuels filled the gap caused by the temporary shutdown of…

Ukraine's Energy Security and the Coming Winter
…partners to help the country meet its energy needs through the challenging months ahead.Ukraine's energy system has been targeted since Russia launched its full-scale invasion of the country in February 2022. These attacks on key infrastructure have recently increased and intensified, posing a huge threat to reliable access to power, heating and communications services across Ukraine this winter.This special report lays out 10 key energy actions to reinforce the country’s energy security – essential to its security overall – at this critical juncture. It will take stock of the war’s impact on Ukraine’s energy sector…

Clean Energy Transitions Programme 2023
…systems this century. The CETP’s work is structured across three pillars of activity, with a particular focus on emerging markets and developing economies. The first of these focuses on supporting emerging and developing countries to establish clean energy transition goals, in line with the objectives of the 2015 Paris Agreement and the Sustainable Development Goals established by the United Nations. The second pillar centres on facilitating coordination among multilateral organisations such as the Group of 20 (G20) and UN-affiliated collaborations. The final pillar showcases the IEA’s work at a global level to enable and accelerate clean energy…
