PPC Renewables Romania is expanding its renewable energy portfolio by integrating battery storage technology into its existing solar power plant in Colibași, Giurgiu County. The project reflects the company’s broader strategy of combining renewable generation with storage solutions to improve system flexibility and grid integration.
The planned battery energy storage system (BESS) will have an installed power of 4.47 MW and a storage capacity of 8.94 MWh. The total investment is estimated at approximately €2.1 million, with around €385,000 expected to be financed through grants from the EU-backed Modernization Fund.
The storage system will be added to the Colibași solar power plant, a 15-hectare facility that has been operational since 2013. The site contains more than 39,000 photovoltaic panels and represents one of PPC Renewables’ established generation assets in Romania.
In addition to the battery installation, the project includes a wider set of infrastructure upgrades. These involve the construction of operation and maintenance facilities, improvements to internal roads and access infrastructure, enhanced perimeter security systems, lighting and monitoring equipment, as well as the development of logistics areas required for daily operations.
By integrating storage into an operational solar plant, PPC Renewables aims to increase the plant’s operational flexibility, enabling excess solar generation during peak production hours to be stored and later delivered when demand is higher or renewable output is lower.
Overall, the investment reflects a broader trend in Romania’s renewable energy sector, where developers are increasingly combining solar assets with battery storage systems to support a more stable, flexible, and modern electricity grid.
