R.Power is nearing completion of its first utility-scale battery energy storage system (BESS) in Romania. Located in Scornicești, southern Romania, the project has 127 MW of power capacity and 254 MWh of storage, with commissioning expected by early 2027.
Construction began in spring, with engineering, procurement and construction contractor Parapet working alongside R.Power’s in-house EPC team.
All 46 battery units and 23 containerised medium-voltage transformer stations have been deployed. The remaining challenge includes completing the extensive design and grid connection works required to connect the facility to Romania’s high-voltage transmission network, operated by Transelectrica.
Once operational, the project will rank among the largest standalone battery storage facilities in Central and Eastern Europe.
The project secured a €46 million financing package in June. The European Bank for Reconstruction and Development (EBRD) provided €44 million in investment and bridge financing, while Poland’s development bank, Bank Gospodarstwa Krajowego (BGK), issued a €2.3 million guarantee supporting the long-term optimisation contract with energy trader GEN-I.
R.Power co-owns the project through a joint venture with France-based Eiffel Investment Group.
R.Power’s battery storage portfolio in Central and Eastern Europe totals 0.9 GW of power capacity and 3 GWh of storage across operational and under-construction projects. A further 0.7 GW and 2.8 GWh of projects are commercialised and ready to build.
Across Europe, the company has more than 13 GW of grid-secured utility-scale battery storage and renewable energy projects spanning Poland, Romania, Germany, Italy, Portugal and Spain.
Romania’s battery storage expansion is moving from project announcements towards large-scale deployment. But delivering storage capacity involves more than installing batteries: grid connection, financing and optimisation arrangements are also essential to bringing projects online and making them commercially viable.
Scornicești highlights both the opportunity and the challenge. With 127 MW of power and 254 MWh of storage, the project will add flexibility to Romania’s electricity system, helping shift electricity between periods of surplus and demand.
As renewable generation grows across Central and Eastern Europe, the pace at which storage projects connect to the grid and secure viable operating models will be an important factor in how effectively the region integrates more renewable power.
