Hungary’s largest battery storage system marks the country’s grid-scale arrival

Greenvolt has commissioned a 99.8 MW / 288.6 MWh battery storage system in northeastern Hungary — the country’s largest operational BESS to date. The project puts Hungary on the map for grid-scale storage in Central and Eastern Europe.

The system is part of a wave of Central and Eastern European storage investment driven by rising renewable penetration and the need for grid flexibility. LONGi, for its part, launched an integrated energy storage and microgrid portfolio targeting Eastern Europe in 2026, reflecting manufacturer expectations of growing C&I demand for energy independence in the region.

Hungary’s grid-scale storage build-out matters for C&I buyers because it establishes the market infrastructure — connection processes, balancing-market participation and financing precedents — that behind-the-meter commercial systems rely on. A country with one operational 100 MW plant is a different market for C&I storage than one without.

For manufacturers and integrators, Central and Eastern Europe is increasingly framed as the next C&I growth front, as Western European residential demand softens and businesses across the region seek storage to hedge against energy-cost volatility.
