History

EuroEnergy's history is rooted in the Greek renewable energy market. According to its official website, the company's journey started in Greece and has seen it expand to become a leading player in the renewable energy sector of Southeast Europe, making it one of a few companies with such an expansive reach. The company states that it was founded in 2007 and that since inception it has completed over €1 billion in transactions. Some of EuroEnergy's earliest and most significant assets are onshore wind projects in the Arkadia Prefecture of the Peloponnese. The Zefyros Project, a 24.0 MW onshore wind farm in the Tripolis Municipality, and the Garbis Project, an 18.0 MW onshore wind farm in the same municipality, both date from 2008. These projects reflect the company's original focus on Greek wind energy and are connected to the legal entity name Windenergy Investments Hellas A.E. & SIA Arkadikos Zefiros E.E. During the early 2010s, EuroEnergy diversified into solar PV and expanded its geographic footprint. In Greece, it developed the Revenia Project (7.5 MW) in the Thiva Municipality of Viotia Prefecture in 2011, followed by the Mpozalo Project (10.0 MW) in the Almyros Municipality of Magnesia Prefecture in 2013, and the smaller Kasiktsi (0.8 MW) and Mitriko (0.6 MW) projects in the Maronia Municipality of Rodopi Prefecture, also in 2013. Abroad, the company built the Irini Project (4.3 MW) and the Atticki Project (4.2 MW) in Lehliu, Calarasi, Romania, both in 2013. By the 2020s, EuroEnergy had broadened its reach further into Central Europe. In 2024, it brought online the Boguszyn 1 and Boguszyn 4 solar PV projects in Boguszyn, Poland, each with a capacity of 10.0 MW. As of July 2024, the company reported a total generating capacity of over 110 MW and a pipeline of approximately 650 MW under development across five countries: Greece, Romania, Poland, Croatia and Latvia. Its portfolio includes more than 180 projects spanning solar, wind, battery storage and biomass, supported by around 20 current and historic financial and banking partners. EuroEnergy describes its vision as the continuous expansion of renewable energy sources in Europe to advance a sustainable and stable green energy future, and its mission as sustainably creating a best-in-class pan-European clean energy portfolio through excellence, innovation and responsibility. The company works across the full project lifecycle, from initial planning and development to construction management and operation across various technologies. It frames its activities as supporting stable energy resources and helping to advance the European Union's goals to reduce greenhouse gas emissions by 55% by 2030 and become climate neutral by 2050.
