Romanian Utility Signs Deal for 10 MW Floating Solar Project on Reservoir

Wedoany.com Report-Jul. 27, Hidroelectrica, a leading Romanian hydropower operator, has signed a contract to develop its inaugural floating solar project, named Nufărul, in Olt County, southern Romania. The project, announced on July 25, 2025, will be executed by Romanian company Waldevar Energy, with support from subcontractors and third-party contributors.

The 10 MW floating solar array will be installed on the Ipotești reservoir, integrating with the existing Ipotești Hydroelectric Power Plant, operated by Hidroelectrica. Upon completion, it will be the largest floating solar installation on a reservoir in Europe, showcasing Romania’s commitment to renewable energy innovation. The system will utilize 620 W solar panels and 100 kW inverters, connected to the national grid via four transformer stations.

Valued at RON 39.2 million ($7.6 million), the project is slated for completion within 14 months, with operations expected to commence by September 2026. The initiative enhances Romania’s renewable energy capacity, supporting domestic electricity consumption and contributing to sustainable energy goals.

Alessandro Amato, CEO of Waldevar Floating PV Systems, highlighted the project’s significance, stating: “The Nufărul pilot project, the largest of its kind in the European Union, represents a functional and efficient integration between hydroelectric and photovoltaic energy.” He added that the pilot marks a key step in leveraging the photovoltaic potential of Romania’s hydroelectric basins.

The Nufărul project follows the recent inauguration of a 74.3 MW floating solar plant in France by Q Energy in June 2025, currently the largest in Europe, built on basins from former gravel pits. Hidroelectrica’s initiative positions Romania as a leader in combining hydroelectric and solar technologies, optimizing existing infrastructure for renewable energy production.

By integrating solar power with its hydropower operations, Hidroelectrica aims to enhance grid reliability and support Romania’s transition to cleaner energy sources. The project underscores the potential for innovative renewable energy solutions in Europe, contributing to environmental sustainability and energy security for local communities.
