Hidroelectrica plans 90 MW floating solar, 800 MWh storage — NRG-IA

Hidroelectrica is preparing a major expansion of the floating solar concept on the reservoirs of its hydropower plants on the Lower Olt River, in a project that combines solar generation, existing hydro infrastructure, and battery storage. According to Profit.ro , the company is market-testing contractors to build floating photovoltaic parks on five reservoirs, with shore-based storage systems, before preparing the tender documentation for the works contract. The technical stakes are high: the project is not just about adding new solar capacity, but an attempt to transform reservoirs into hybrid platforms where hydropower, solar, and batteries can work together to cover imbalances and provide system services. A 90 MW solar and 800 MWh storage project The scheme presented by Profit.ro includes the "Nufărul" pilot component, associated with the Ipotești hydropower plant, featuring 10 MW of solar PV and a 40 MW / 160 MWh storage component. The expanded project also plans four 20 MW solar…
