Green Energy Investhor project to be developed with 499 MW capacity
Green Energy Investhor Zrt. (GEI) is launching a large-scale wind farm development project in the Kisalföld region: the project, planned within a 15-kilometre radius of Vadosfa, will feature 70 state-of-the-art wind turbines, creating a total of 499 MW of new installed capacity and is expected to generate 1,200 GWh of electricity annually. The investment is already at the construction permitting stage. The project will nearly triple Hungary’s current installed wind capacity of around 330 MW, representing a meaningful step in expanding the country’s renewable energy production and greening its energy mix.
Budapest, 25/02/2026 – Hungary currently has around 330 MW of installed wind power capacity in operation, which has not expanded significantly over the past decade. Solar energy has so far played the dominant role in the green transition of the domestic energy system, while wind energy has remained untapped. Green Energy Investhor’s (GEI) new development project is being launched in this renewable energy landscape; it will be implemented in the Kisalföld region, within a 15-kilometre radius of Vadosfa, with 70 turbines, each with a unit capacity of 7-7.2 MW, increasing domestic wind capacity by 499 MW. Expected annual production is 1,200 GWh – meaning that the power plant would be able to meet the electricity needs of the entire country for 10 days – while the technology’s annual utilisation, at around 2,500 operating hours, is nearly twice the average for solar power plants.
“The Vadosfa wind farm is a milestone in domestic renewable energy production. We are implementing a development on a scale that, after a long period, will once again bring substantial growth to the Hungarian wind energy sector,” said Antal Ritter, CEO of Green Energy Investhor. “We are thinking in the long term: our aim is to contribute to Hungary’s energy security and climate goals by applying state-of-the-art technologies, while taking both natural and social considerations into account.”
The project has reached an important milestone
The investment is currently at the construction permitting stage. Preparations for the project, however, have been under way for some time: the year-long environmental observations and measurements were completed in January, and with the data from these available, the permitting process could begin. Archaeological trial excavations have also begun at the site. Construction of the connection and feeder network may begin at the end of 2026, with the first tower planned to be erected in the first quarter of 2028. The full wind farm could enter operation at the end of 2029 or the beginning of 2030.
The turbines’ tower height may reach 130 metres, with an overall structure height of 220 metres, while the 90-metre rotor diameter ensures efficient operation even at lower rotational speeds. When selecting the components, a fundamental criterion is that noise and vibration levels remain below regulatory limits at all times of day, while maintaining distances from residential and holiday areas that typically exceed 1 kilometre, rather than the minimum 700 metres required by law.
Nature conservation is a strategic consideration in the development
During the development, GEI pays particular attention to protecting the area’s natural assets. Continuous wildlife monitoring took place in the area for one year, including bird and bat monitoring, field data collection and seasonal surveys. Based on these findings, environmental impact studies and the necessary action plans are being prepared with the involvement of independent environmental and regulatory experts. The aim is not merely to comply with legislation, but to ensure that the operation of the wind farm can be aligned with the characteristics of the local ecosystem in the long term. To this end, the plans include, for example, operation adjusted to sensitive periods, the use of temporary shutdown protocols where necessary, and the optimisation of turbine placement and operation in a way that minimises impacts on wildlife. All this includes adaptation and monitoring requirements not only for the construction period, but also for the entire 25–30-year operating cycle.
Dialogue with local communities
GEI ensures the involvement of local communities both during and beyond the permitting procedures, maintains dialogue with the municipalities, property owners and farmers concerned, and is preparing environmental education and awareness programmes in the area.
The infrastructure developments required to implement the project – primarily the renovation and reinforcement of existing municipal roads – affect settlements in several counties, with the aim of ensuring that the upgraded road sections remain available to local communities after construction.
