Italian company Heliopolis, headquartered in Milan with branches in Timisoara and Bucharest, has announced a large-scale hybrid renewable energy project in southeastern Romania, featuring over 400 MW of solar capacity and nearly 1,000 MWh of battery storage.
The development, located in Calarasi county, is considered one of Romania’s most significant integrated solar-and-storage initiatives. Heliopolis confirmed that the project has now reached ready-to-build status.
The initial phase includes four hybrid plants combining 307 MW of solar with a 224 MW / 976 MWh battery system, all connected through a single 400 kV network access point. Heliopolis noted that this is only the first stage of a larger plan, with work already underway to expand the installation to 600 MW of solar and 450 MW, 4-hour battery storage, strengthening the company’s role in Europe’s energy transition and development of strategically important energy infrastructure.
