ENGIE ROMANIA TO BUILD TWO BATTERY ENERGY STORAGE SYSTEMS IN GALAȚI AND SIBIU

Engie Romania, a subsidiary of the French energy group Engie, announced plans to develop two large-scale Battery Energy Storage Systems (BESS) in the Romanian counties of Galați and Sibiu. While the investment value has not been disclosed, both projects are expected to significantly enhance Romania’s energy stability and grid flexibility.

BESS in Galați

The first battery storage facility will be built at Engie Romania’s 50 MW wind farm in Băleni (Galați County).

-         Construction start: Q1 2026

-         Commissioning: Summer 2026

-         Technology: Lithium Iron Phosphate (LFP)

-         Power: 5 MW, Storage Capacity: 10 MWh

Once operational, the system will be capable of delivering power to the grid for two continuous hours, helping to reduce network imbalances and support renewable integration.

BESS in Sibiu

The second facility will be constructed in Șelimbăr (Sibiu County), on a 2-hectare site recently acquired by Engie Romania.

-         Construction start: November 2025

-         Commercial operation: Q4 2026

-         Technology: Lithium Iron Phosphate (LFP)

-         Power: 80 MW, Storage Capacity: 160 MWh

Engie Romania is also considering expanding the storage duration from two to four hours, potentially doubling its balancing capacity.

European Energy Transition Context

Both BESS projects align with Engie Group’s global strategy to reach 95 GW of renewable and storage capacity by 2030.
Engie Romania currently operates over 250 MW of renewable generation (wind, solar, and biomass) and continues to invest in energy transition and grid modernization projects across the country.

Commentary by the Institute of Danube Research:

“The development of Engie Romania’s BESS projects in Galați and Sibiu represents a key step in strengthening the energy resilience of the Danube region, where integrating renewables requires effective storage and flexibility solutions.

These initiatives will support decarbonization, grid stability, and cross-border energy cooperation between Romania and Ukraine, contributing to the creation of a shared ‘green corridor’ in the Danube basin.

This is a strong example of how private investment can drive the European Green Deal’s climate goals,”
— noted the Institute of Danube Research.
