PPC Renewables Romania is integrating battery storage into its existing solar power plant in Colibași, Giurgiu County. The company said the expansion is part of a wider approach that pairs renewable generation with storage technology. The project is designed to improve system flexibility and grid integration through the addition of a battery energy storage system.
Colibași BESS specifications and financing
The planned battery energy storage system (BESS) will be built with an installed power of 4.47 MW and a storage capacity of 8.94 MWh. Total investment for the project is estimated at approximately €2.1 million. Of that amount, around €385,000 is expected to be financed through grants from the EU-backed Modernization Fund.
Solar plant details and operational footprint
The battery installation will be added to the Colibași solar power plant, a 15-hectare facility that has been operating since 2013. The site includes more than 39,000 photovoltaic panels. PPC Renewables described the asset as one of its established generation facilities in Romania.
Associated works for operations and site upgrades
Alongside the battery equipment, the project includes infrastructure upgrades across the plant area. Works cover construction of operation and maintenance facilities, improvements to internal roads and access infrastructure, and enhanced perimeter security systems. The scope also includes lighting and monitoring equipment, as well as logistics areas required for daily operations.
Storage role within the operational solar site
PPC Renewables said integrating storage into an operating solar plant is intended to increase operational flexibility at Colibași. The arrangement would allow excess solar generation during peak production hours to be stored. Stored electricity would then be delivered when demand is higher or when renewable output is lower.
