Ukraine is showing how energy systems must evolve to survive. And Europe is listening. At the Architecture of Security conference in Kyiv earlier today, I warned that no country is fully prepared for a world in which critical infrastructure is seen as a target of war. Days earlier, at the invitation of our partners E.ON, I spelt out to their networks leadership group what that threat means in practice for European security. Since 2022, DTEK has lost the vast majority of its capacity on multiple occasions - and each time we have rebuilt it. What works: 🤝 Strong coordination 🇪🇺 European integration 🔋 Decentralised energy 👤 And above all -people who refuse to give up.  My thanks to Thomas Konig for E.ON's support and my fellow panelists earlier today: Minister Denys Shmyhal, former US Ambassador to Ukraine and DTEK Advisory Council Chairman Geoffrey Pyatt; Olena Pavlenko of DiXi Group and Volodymyr Kudrytskyi.

Each time I’ve met Oleksandr, I've left with the same impression: of a man with focus, determination and humanity. A Ukrainian to the core. DTEK is proud to support @usykaa this weekend. 🇺🇦🥊

We have paid a huge price to keep the lights on in Ukraine since 2022. This morning at the @GermanyDiplo , I set out key lessons in energy security that DTEK has learnt in more than four years of war. Three takeaways that the rest of Europe should take on board: 1. People - You need a highly trained team who know exactly what to do in an attack and who stay motivated whatever the challenge. 2. Planning - From high-level system design to making sure you have the right spare parts, understand your vulnerabilities and act now. 3. Protection - From concrete blocks to multi-layered air defences, Ukraine's experience is today relevant to every country in Europe. Grateful to the German Government and my fellow speakers: Minister of Energy Denis Shmyhal, Mihai Popsoi , Minister of Foreign Affairs of Moldova, Jean-Charles Ellermann-Kingombe, NATO Assistant Secretary General for Cyber Defence and Digital Transformation, Stefan Kapferer, CEO 50Hertz Transmission GmbH, Olena Pavlenko, President DiXi Group think tank. Moderator: Olga Khakova, Fellow Atlantic Council Global Energy Center (GEC).

Grateful for the engagement of international and Ukrainian media who joined us in Kyiv last week to hear the latest on Ukraine’s energy system and our plans to strengthen it. After four years of full-scale war and the toughest winter in our history, the lesson is clear – resilience depends on preparation, discipline and delivery as much as heroism. That is why DTEK is working around the clock and investing heavily to prepare for another winter. There is a huge amount to do in the next six months, but my message to assembled journalists was one of confidence. Not only is Ukraine becoming sovereign in its energy needs, but with Europe looking for new and closer sources of energy supply, Ukraine has a pivotal role to play. By DTEK's actions, we are demonstrating that investing in this future today is possible.

I’ve spent the past few days at CERAWeek, where one theme stood out: energy security is no longer a regional issue for Ukraine and Europe — it’s now a global concern. In such uncertain times, Ukraine may not seem an obvious destination for investment. However, that view is changing fast. I’m hearing global energy leaders talk more about ways to mitigate risk to access Ukraine. They want energy sources that are closer to European markets; and see the scale, speed and hard‑won operational expertise we bring. Just a snapshot of those opportunities: ➡️Little-explored gas reserves (second biggest in Europe) ➡️The largest gas storage on the continent ➡️Large-scale wind and battery storage potential ➡️A ready market for LNG imports from the US ➡️A growing need for gas-fired generation to provide fast and flexible power ➡️And an energy system poised for a decade long-transformation guided by the need for energy security as we rebuild from war. This transformation is happening in real time and under extreme pressure. Today, Ukraine the world’s largest proving ground for new energy technologies. Encouraging discussions at @CERAWeek showed that the decisions we make now will shape not just Europe’s energy future, but global security too. My thanks to those I have met this week, including U.S. Secretary of @ENERGY @SecretaryWright, Ministers Katherina Reiche, Stavros Papastavrou and Žygimantas Vaičiūnas, Ukraine’s Minister of Energy @Denys_Shmyhal, @JJovanovicUSA from U.S. EXIM, Erica Ehst from DFC, Josh Volz, Special Envoy for Energy Integration, former U.S. ambassadors to Ukraine @geoffpyatt and Carlos Pascual, Roman Kramarchuk of S&P Global and energy leaders from @Halliburton, @DevonEnergy, @EQTCorp, @bakerhughesco, @Venture_Global, @Cheniere, @OneCarlyle Energy, @uniper_energy and RWE.

In four years of full-scale war, we never backed down in the face of russia’s energy terror. And we never will. Despite unprecedented attacks, the commitment, bravery and ingenuity of people across the energy sector continues to get us through this, the hardest winter in our history. This morning, I told the @BBCNews' @HockingsLucy how we have survived, and why we will emerge stronger.

Useful discussions at Munich Security Conference #MSC2026 over the weekend – much of it focused on how international partners can help protect Ukraine’s energy infrastructure from relentless russian attacks. It was clear to me that Ukraine’s allies continue to stand shoulder to shoulder with us and we are grateful for the tireless efforts of President Zelenskyy in drawing global attention to our fight for survival. The next step is turning every expression of solidarity into action. Specifically, I spoke with leaders about Ukraine’s immediate energy needs: ➡️ Protecting energy infrastructure with greater air defence weaponry, and ➡️ Supporting the immediate energisation of Ukrainian homes with mobile generators and equipment to repair damaged power stations and the grid. Just as importantly for Europe, my message to industrial, political and military leaders in Munich is that they learn from Ukraine’s energy war and never underestimate the depths that russia will sink. Daily attacks on our power plants and substations prove that no nation or people are safe if they lack energy security. The defence of this infrastructure is vital to national security meaning investment in battle-tested, decentralised energy systems has never been more urgent. Grateful for the engagement in Munich, including with industry partners Christian Bruch, Markus Rauramo, Stefan B. Wintels and Mohamed Jameel Al Ramahi, US colleagues such as @ChrisRuddyNMX and Jarrod Agen and European interlocutors including Minister Katherina Reiche, EU Commissioner @MartaKosEU, Lithuania’s Zygimantas Vaiciunas, German Eastern Business Association and @Eurelectric’s @kristianruby.

Getting Ukraine through the deepest energy crisis in our history this winter will require global support. We need missiles for our air defence systems; equipment like mobile generators for frozen apartment blocks and transformers for bombed out power stations; and we urge further diplomatic efforts that would lead to a renewed energy ceasefire to save what russia has not already destroyed. Yesterday I was at #IEW26 in London making the case for more materiale and support, and I will be doing the same at the Munich Security Conference this weekend. While in London, I was honoured to be made an Honorary Fellow of the Energy Institute. I accepted it on behalf of every energy worker in Ukraine for the brave and life-saving work they are carrying out, day in and day out, in the service of our country. Thank you to @CordiOHara_NG, Dr Nick Wayth and Andy Brown at the @EnergyInstitute for all the support and solidarity you are providing.

While the world watches on, russian drones and missiles are dismantling the remaining pieces of Ukraine's energy system. Last night, it fired 40 missiles and 400 drones against us, destroying substations, transmission lines and power plants. Two DTEK power stations were badly hit and we are assessing the damage now. With temperatures dropping to -20C (-4F) by Monday, their objective is obvious: to maximise human suffering. If we don't get more air defence ammunition and stronger diplomatic support soon, Ukraine's energy crisis will quickly turn into a humanitarian crisis.

During a visit to oversee recovery work at damaged DTEK power station earlier today, I received terrible news that a bus carrying DTEK coal miners nearby had been hit by russian drones, killing at least 12 people and injuring 16 others. Details are still emerging, but we can already say with certainty that this was an unprovoked terrorist attack on a purely civilian target, for which there can be no justification. This attack marks the single largest loss life of DTEK employees since russia's full-scale invasion and is one of the darkest days in our history. DTEK teams are working with emergency services on the ground in Dnipropetrovsk region to ensure the injured, and families who have lost loved ones, get all the care and support they need. Their sacrifice will never be forgotten.
