The Studina solar project in Romania has officially entered commercial operation, becoming the country’s largest operational solar facility to date. The 174 MWdc plant marks a significant step toward strengthening Romania’s energy security and accelerating the transition to cleaner power sources across Southeast Europe.
The project was developed by CWP Europe in partnership with Renalfa, as part of the company’s broader strategy to expand renewable energy investments and support the region’s energy transition.
The Studina facility is expected to generate around 245,000 MWh of electricity per year, enough to supply more than 122,500 households while avoiding approximately 220,500 tonnes of CO₂ emissions annually.
The project was delivered with the support of Siemens Energy, Solarpro, and Eximprod, highlighting the role of international and regional partnerships in bringing large-scale renewable projects online.
Viktor Garbev, Executive Vice President at CWP Europe, said:
“Enabled by our local teams, this project demonstrates our ability to secure sites, build strong partnerships, optimize permitting, and deliver real assets at scale in complex technical and regulatory environments.”
At 174 MW, Studina is currently the largest operating solar project in Romania, reflecting the rapid expansion of the country’s renewable energy sector. Several larger projects are already under development, signaling strong investor interest and continued growth in the solar market.
The project’s commissioning also points to improving investment conditions, supported by regulatory efforts to streamline permitting and grid connection procedures.
The project has already secured a permit for a co-located battery energy storage system, with construction planned for the next stage. The addition of storage is expected to improve grid stability, reduce solar output variability, and enhance the overall performance of the asset.
More broadly, projects that combine generation and storage are becoming increasingly attractive to investors, as they offer greater flexibility and more predictable returns. For policymakers, such developments provide practical examples of how renewable expansion can be aligned with grid reliability and long-term energy security.
