Romania's large-scale and residential energy storage markets are both expanding rapidly.

Located in southeastern Europe, Romania is rapidly emerging as a new hotspot in Europe’s renewable energy landscape, thanks to its abundant natural resources and a continuously improving policy environment.

In 2025, Romania accelerated the structural adjustment of its power energy sector, marked by a sharp contrast between the phase-out of traditional coal-fired power and the rapid expansion of renewable energy.

Driven by the phase-out of coal-fired power and the acceleration of renewable energy, Romania's total installed power capacity increased by 567 MW in 2025, reaching a cumulative capacity of 19.178 GW by the end of the year. Wind and solar power each accounted for over 16% of the total capacity.

The demand for grid flexibility in Romania continues to increase, and large-scale energy storage projects have evolved from being a "supplementary option" to a "system necessity."

The table below presents Romania's large-scale, grid-connected battery energy storage projects as of December 5, 2025.
