The Greek energy group has launched a Romanian subsidiary to oversee its expansion, with a 96 MW wind farm due for completion in 2027 and a wind-and-battery project planned for 2029.
Greece’s HELLENiQ ENERGY plans to invest more than €1 billion in Romania by 2030, targeting a portfolio of up to 1.3 GW in renewable power generation and battery storage. The group presented the four-year program in Bucharest on November 9, when it officially launched HELLENiQ Renewables Romania. The company ranks Romania as its most important market for renewables growth outside Greece.
The investment builds on a Romanian portfolio that already includes more than 800 MW of solar and wind projects and more than 500 MW of battery storage projects at various stages of development. CEO Andreas Shiamishis called Romania “a key part of our long-term growth plans in Southeast Europe.”
Solar projects laid the groundwork for expansion
HELLENiQ began building its Romanian solar business in 2023 through an agreement with Greek industrial group METLEN to develop and acquire four photovoltaic parks. The first two, with a combined capacity of 58 MW, entered commercial operation in the first quarter of 2026. In its November 10 regulatory filing, HELLENiQ reported 211 MW of solar capacity in operation across the four parks in Teleorman, Giurgiu, Olt and Dolj counties. The company estimates their combined annual output is equivalent to the electricity consumption of more than 155,000 households.
Wind projects advance in Galați and Vaslui
The next major project is a 96 MW wind farm under construction in Galați County. HELLENiQ expects to complete it in the second quarter of 2027 and estimates it will produce enough electricity annually to match the consumption of more than 150,000 households. The company has also identified more than 500 MW of additional wind and solar projects at advanced stages of development in Romania.
In Vaslui County, HELLENiQ is developing a larger project that would pair a 186 MW wind farm with a battery system rated at 186 MW and capable of storing 186 MWh of electricity. The project is slated for the second quarter of 2029, according to Balkan Green Energy News. Pairing the two technologies would allow the project to store electricity when wind output is high and dispatch it later, giving the operator more flexibility over when it supplies power to the grid.
The Romanian program accounts for more than €1 billion of a wider investment push
HELLENiQ expects its total investment in renewables and storage to exceed €2 billion by 2030. The Greek refiner currently operates more than 800 MW of renewable capacity across Greece, Romania, Bulgaria, Cyprus and North Macedonia. It aims to bring its installed renewable generation capacity above 2 GW by the end of the decade, drawing on a project portfolio of more than 6 GW.
For HELLENiQ, Romania offers room to expand both power generation and storage within a single market. The company said it is continuing to assess further investments and partnerships in the country as it builds out the solar, wind and battery projects already in its portfolio.
