DTEK is pleased to announce the appointment of Geoffrey Pyatt, former US Ambassador to Ukraine, as the new Chairman of its Advisory Council. This appointment will enhance the Council's mission as a forum for independent, high-level guidance to the Group on issues including energy security and resilience, long-term recovery and sustainability.

In his new role, Ambassador Pyatt will lead the Advisory Council’s work, ensuring its collective expertise delivers practical, actionable guidance. Externally, he will advocate further for the major contribution Ukraine can make to Europe’s energy security and advise DTEK on ways it can accelerate the integration of Ukraine’s and the EU's energy systems.

Ambassador Pyatt brings over 35 years of expertise in diplomacy and energy policy. As the Assistant Secretary of State for Energy Resources from 2022 to 2025, he led US diplomacy to bolster Ukraine's energy resilience and counter russia's weaponisation of energy resources. Ambassador Pyatt was instrumental in securing energy security partnerships and critical mineral agreements with allies.

From 2013 to 2016, he served as the US Ambassador to Ukraine, working as America’s top diplomat in the country during the Revolution of Dignity (Maidan Revolution) and the subsequent russian invasion in 2014. From 2016 to 2022, he served as US Ambassador to Greece.

Commenting on his appointment, Ambassador Pyatt said, “The Advisory Council brings together exceptional global expertise at a pivotal moment for Ukraine and Europe’s energy future. I am committed to ensuring the Council’s work delivers practical, high-impact insights that strengthen Ukraine’s energy resilience, advance its integration with Europe, and deepen cooperation between Ukraine, the US, and our international partners.”

DTEK CEO Maxim Timchenko said: “Ambassador Pyatt brings exceptional experience at a moment when Ukraine’s energy future is inseparable from global security and transatlantic cooperation. His leadership will strengthen the Advisory Council’s role as a source of practical, independent guidance as we work to reinforce energy resilience, accelerate recovery and deepen Ukraine’s integration with Europe and its partners.”

The DTEK Advisory Council brings together policymakers, experts, diplomats and civil society leaders for regular discussions on the strategic direction of the Group. Its work focuses principally on supporting Ukraine’s integration into Europe’s energy market, strengthening international energy connections and enhancing Europe’s overall energy security.

The appointment was announced at a recent meeting of DTEK’s Advisory Council in London, where members examined the rapidly evolving geopolitical, economic and energy landscape facing Ukraine and Europe. Discussions focused on strengthening energy security and accelerating investment, with particular emphasis on market reforms and privatisation as drivers of modernisation in Ukraine’s energy sector. The Council also underscored the critical role of international financial institutions and private capital in supporting Ukraine’s long-term energy resilience.

The Council also discussed the upcoming Ukraine Recovery Conference in Gdansk, Poland and the opportunities to strengthen international partnerships and attract investment into Ukraine’s energy sector.
