Hungary has increased the grid-connection capacity available to prospective wind farms to almost 1 GW, exceeding its earlier 700 MW commitment after developer interest proved stronger than expected.
The additional capacity was identified through an assessment of potential development areas that considered environmental restrictions, defence requirements and grid conditions. The review allows the authorities to allocate a larger connection envelope without opening every part of the country to wind development.
The Hungarian Energy and Public Utility Regulatory Authority is conducting a detailed technical evaluation, with completion expected by mid-August. Hungary then plans to hold its first competitive auction for wind-power connection rights.
Draft tender rules are due to enter public consultation before the auction. The framework is expected to require energy storage at locations where batteries or other flexible assets are needed to manage grid constraints and renewable variability.
This is a significant shift in the Hungarian market. Grid access has become one of the most valuable and scarce development rights across central and south-eastern Europe. An award of connection capacity does not by itself produce a bankable wind project, but it removes one of the principal barriers facing developers.
Projects will still need land rights, environmental approvals, wind-resource studies, construction permits, equipment procurement and credible routes to market. Storage requirements could improve system integration but would also raise project CAPEX and introduce additional revenue assumptions into financing models.
Energy Minister István Kapitány has presented the initial auction as the first stage of a programme intended to make at least 4 GW of additional wind connection capacity available by 2030. Delivering that volume would require substantial reinforcement of transmission and distribution infrastructure, particularly where new projects are concentrated away from existing high-capacity substations.
Hungary’s power system already experiences large swings between low solar-driven daytime prices and expensive evening hours. Wind has a different production profile from solar and could improve portfolio diversification, particularly during winter and overnight periods. Its capacity factor and seasonal value will therefore be important to the economics of the auction.
The first 1 GW round will establish the market price of Hungarian grid access and reveal how developers value projects that combine wind, storage and potentially merchant electricity exposure.
