Strategic projects to modernize the grid and strengthen energy security
Engie Romania will build two battery energy storage systems located in the counties of Galați and Sibiu. These investments are part of the company’s strategy to modernize the national energy system and reach a global installed capacity of 95 GW in renewable energy and storage by 2030.
Galați system – storage near the Băleni wind farm
The first system will be located next to the operational wind farm in Băleni commune, Galați County, which has an installed capacity of 50 MW. Construction is scheduled to begin in the first quarter of next year, with commissioning estimated for the summer of 2026.

The battery system will have a power output of 5 MW and a storage capacity of 10 MWh, using LFP (lithium iron phosphate) technology. The configuration allows for energy delivery to the grid at maximum capacity for two hours, with the possibility to extend up to four hours, depending on future grid needs.
The system will absorb surplus energy when production exceeds grid capacity and will provide frequency regulation and balancing services for the wind power plant.
Sibiu system – a “Ready-to-Build” project
The second project will be located in Șelimbăr, Sibiu County. Engie Romania has recently acquired the rights to the project, with construction expected to start in November 2025.
The project is in the “Ready-to-Build” phase, with all necessary permits obtained. Commercial operation is scheduled for the fourth quarter of 2026. The system will have an installed power of 80 MW and a storage capacity of 160 MWh. It will be built on a two-hectare site and will use the same LFP technology.
Engie focuses on flexibility and sustainability
“Flexibility solutions such as battery energy storage are becoming essential for the stability and resilience of the energy system. These two projects strengthen Engie’s position as a trusted partner in the energy transition and reaffirm our commitment to a sustainable, decarbonized future. In addition, we plan initiatives that will increase our total installed battery storage capacity to approximately 300 MW by 2030,” said Cristian Buzan, Vice President of Engie Romania.
The company highlights that these investments will contribute to a more flexible energy grid, capable of managing fluctuations in production and consumption more efficiently at the national level.
