The Topic
Hungary is commissioning larger battery storage projects and developing additional capacity to manage fluctuations from its expanding solar and wind generation. New systems in Buj, Sopronkövesd and Tiszaújváros are designed for grid balancing, ancillary services and renewable-energy integration, while Veolia is planning storage alongside flexible gas generation to address evening demand peaks during heatwaves. The expansion is supported by EU funding and government plans, but reported capacity figures vary by project scope, timing and measurement method.

Summary
- Greenvolt commissioned a combined 99.8 MW and 288.576 MWh battery system in Buj, described as Hungary’s largest and the region’s largest at commissioning.
- MVM opened a 10 MW lithium-ion system paired with a wind farm in Sopronkövesd, while MOL commissioned a 40 MWh system at its Tiszaújváros industrial site.
- Storage projects are being used for frequency response, ancillary services, automated grid balancing and improved integration of solar and wind generation.
- Veolia says evening heatwave demand is creating a sharper need for storage and flexible generation as photovoltaic output falls after sunset.
- EU Recovery and Resilience Facility funding is supporting multiple projects, alongside broader plans for grid upgrades and more renewable capacity.
- Hungarian officials and companies are targeting substantially more storage, although reported current-capacity figures are not fully consistent.
History
The story now centers less on initial battery buildout and more on larger-scale commissioning, with clearer capacity figures and a new emphasis on heatwave-driven evening demand. Veolia’s flexible-generation pairing and the addition of new project sites broaden the operational use case beyond simple renewable balancing.
