Romania's power storage capacity reached 1,130 MWh [1] by the end of March, supported by 31 operational electricity storage facilities [1].

This expansion of storage capacity is critical for stabilizing the national energy grid, allowing for better management of intermittent renewable energy sources and reducing reliance on traditional power plants.

According to data provided by Transelectrica, the current network of storage facilities provides a combined delivery and charging power of 599 MW [1]. This infrastructure allows the grid to absorb excess energy during periods of low demand and release it during peak hours.

On December 17, 2025, a new battery energy storage system (BESS) was commissioned in Cluj County [2]. The project, commissioned by Nova Power & Gas, provides a capacity of 200 MW/400 MWh [2]. This facility represents the largest battery storage project in the country to date.

Romanian Energy Minister Bogdan Ivan said, "Romania commissions 400 MWh battery storage project, its largest to date" [2].

Private investments continue to drive the growth of the energy sector. The increase in total capacity is attributed to the combination of existing operational facilities and new private investments such as the Nova Power & Gas project [1, 2].

“Romania's power storage capacity reached 1,130 MWh by the end of March.”

The growth in Romania's energy storage capacity indicates a shift toward a more resilient and decentralized energy grid. By integrating large-scale battery storage systems, Romania is reducing the risk of blackouts and improving the possibility of integrating more integrating more volatile renewable energy sources like wind and solar into the national power supply.
