- Terna Energy Societe Anonyme Commercial Technical Company Terna Energy Societe Anonyme Commercial Technical Company (TREAF) operates as a leading renewable energy producer and developer, focusing on the construction, ownership, and operation of wind farms, hydroelectric projects, photovoltaic parks, pumped storage facilities, hybrid power plants, biogas projects, and waste-to-energy installations; it also engages in concessions for infrastructure projects including municipal waste treatment and unified waste collection systems. The company serves markets in Greece, the Balkans, Eastern Europe, Poland, Bulgaria, and North America, with a total installed capacity exceeding 1,200 MW primarily from wind, solar, hydro, and biomass sources as of late 2024. Founded in 1997 and headquartered at 85 Mesogeion Avenue in Athens, Greece, Terna Energy functions as a subsidiary of Masdar Hellas Single Member S.A., following Masdar's completion of a landmark 100% acquisition in April 2025 after initially securing 70% ownership in November 2024 at an enterprise value of €3.2 billion, marking the largest transaction on the Athens Stock Exchange and positioning the company as a core platform for Masdar's European renewable expansion toward a 100 GW global portfolio by 2030. This strategic shift from its prior affiliation with GEK TERNA Group enables accelerated development, including hybrid energy storage projects like the Ai Stratis island initiative for energy independence and biogas plants in the Peloponnese region. Terna Energy maintains a workforce of approximately 300 employees and targets 6 GW operational capacity by 2029 through ongoing project pipelines in wind, solar, and energy storage across its operational regions.
