Energy storage in Hungary
Current regulatory developments
Updated September 2026
Large-scale storage support program. Hungary’s 2024 competitive corporate storage tender awarded non-repayable CAPEX grants and ten-year revenue compensation to projects representing approximately 440 MW of planned storage capacity
First major bank-financed project completed in January 2026 under the support scheme
Regulatory changes introduced in 2025 facilitate the addition of BESS to renewable-generation projects at a shared grid connection point, supporting cable pooling and more efficient use of constrained connection capacity
Rapid PV uptake — above 8 GW by 2025 — is driving demand for balancing and ancillary services, grid-scale and co-located storage
The utility-scale market is moving from pilot projects to commercial deployment
Large-scale storage support program. Hungary’s 2024 competitive corporate storage tender awarded non-repayable CAPEX grants and ten-year revenue compensation to projects representing approximately 440 MW of planned storage capacity. Supported projects are required to operate for at least ten years and participate in the balancing market
First major bank-financed project completed in January 2026 under the support scheme. In January 2026, Greenvolt secured EUR 58.9 million of project financing from UniCredit Bank Hungary for a 99 MW / 288 MWh standalone BESS. The project benefits from ten-year revenue support awarded under the 2024 tender
Shared grid connections and co-location framework improved. Regulatory changes introduced in 2025 facilitate the addition of BESS to renewable-generation projects at a shared grid connection point, supporting cable pooling and more efficient use of constrained connection capacity
Rapid solar deployment is increasing flexibility requirements. Rapid PV uptake - above 8 GW by 2025 - is driving demand for balancing and ancillary services, grid-scale and co-located storage
The utility-scale market is moving from pilot projects to commercial deployment
Five things to know about BESS in Hungary.
BESS is expressly regulated and may require a dedicated storage license. Hungarian electricity law recognizes electricity storage activities but the regime remains closely linked to power-plant-style licensing. As a general rule, power-plant and generation provisions apply correspondingly to BESS irrespective of output capacity. The applicable license, permitting and notification route depends on project specifications.
Balancing services are central, but revenue stacking is developing. Revenue streams include balancing and ancillary services, including FCR and aFRR. Supported projects may also benefit from 10-year revenue compensation / cap-and-floor-style support awarded through public tender, improving bankability. Participation in balancing markets is subject to the TSO prequalification and technical requirements.
Public support has accelerated the market, but availability is program-specific. Hungary’s 2024 storage tender combined investment aid with ten-year revenue compensation and targeted approximately 440 MW of new capacity. Future support must be assessed under the terms of the relevant funding call.
Hungary is a major European battery manufacturing hub, supported by the National Battery Industry Strategy 2030 and investments from CATL, Samsung SDI and others. PV capacity above 8 GW by 2025 creates strong domestic need for flexibility and co-located storage.
Grid access and revenue bankability remain the principal challenges. Although Hungary has introduced dedicated support mechanisms and an increasingly supportive framework for utility-scale BESS, project viability continues to depend primarily on grid connection availability, revenue stacking, balancing-market participation and the long-term bankability of merchant revenues.
