SIO at SuperReturn Energy Transition 2026

SIO participated in SuperReturn Energy Transition 2026, one of Europe’s leading institutional private markets conferences dedicated to energy transition investing. Managing Partner Kostis Tselenis joined the LP panel Perspectives from the Capital Source: LPs’ Evolving Interpretations of Energy Transition, alongside the European Investment Fund, the Ireland Strategic Investment Fund, and other institutional allocators, discussing how LP expectations are reshaping fundraising, governance and portfolio construction in the sector.

Beyond the main stage, SIO also contributed to investor roundtables on real estate, water, and the energy–food nexus, reinforcing its value-chain approach to the transition economy, from storage and grid flexibility to resilient infrastructure and climate adaptation.

We will have the honour of joining Alexandra Mitsotaki at the World Human Forum’s 3rd Symposium for a New Eleusis, to explore how Impact Investing can align profit with purpose, mobilising capital for reforestation, regenerative agriculture, water security, and biodiversity protection.

We will reflect on the third wave of Nature Finance that is emerging: a shift in values from seeing nature as a resource to recognising it as a living system built on contributions, stewardship, and trust.

Join us at the Old Oil Mill Factory in Elefsina, Athens, on the 26th of September. More information
