Green Energy Investhor Wind Farm in Hungary

Green Energy Investhor is acquiring permits to build a 499 MW wind farm on the outskirts of Vadosfa (NW Hungary), the company told MTI on Wednesday.

The planned investment will create a total of 499 megawatts (MW) of new installed capacity with 70 modern wind turbines (each with a unit capacity of 7-7.2 MW), which is expected to generate 1,200 gigawatt hours (GWh) of electricity annually.

Hungary currently has approximately 330 MW of installed wind power capacity, which has not expanded significantly over the past decade. Solar energy has played a key role in the green transition of the domestic energy system so far, while wind energy has remained untapped, they said.

According to the announcement, the investment is currently in the building permit phase. A year of environmental monitoring and measurements was completed in January, and with this data in hand, the permitting process could begin.

Archaeological sample excavations have begun on site. The construction of the connection and transmission network is expected to start at the end of 2026, with the first tower planned to be erected in the first quarter of 2028. The entire wind farm is expected to be operational at the end of 2029 or early 2030.

The turbines will have a tower height of up to 130 meters, a total structure height of 220 meters, and a rotor diameter of 90 meters, ensuring efficient operation even at lower speeds. When selecting the components, a key consideration is that noise and vibration levels remain below regulatory limits at all times of the day, with a distance of typically more than one kilometer from residential and recreational areas, instead of the minimum 700 meters specified by law, the company said.
