25th wind turbine in the Gollenberg wind farm
The project
In the south of Rhineland-Palatinate, another wind turbine was connected to the grid in the summer of 2025. The new Vestas V162 at the ‘Gollenberg’ site, around 20 kilometres south-west of Speyer, feeds climate-friendly electricity into the distribution network. With an expected annual output sufficient for around 5,000 households, the 5.6-megawatt turbine makes a significant contribution to the regional energy supply. Compared to conventional power generation, it avoids around 9,500 tonnes of CO₂ annually.
Every wind turbine sends a strong signal about the urgent need to expand renewable energy. The expansion of renewable energy is a key pillar of a sustainable and reliable energy supply in Rhineland-Palatinate.
Progress in wind energy
Over the last twenty years, wind power technology at Gollenberg has made enormous strides. The first wind turbine, installed in 2003 – a GE unit with a capacity of 1.5 MW and a rotor diameter of 77 metres – generates around 2.5 million kilowatt-hours of electricity per year. Thanks to its 5.6 MW capacity and a 162-metre rotor, the new Vestas turbine can generate up to 12.5 million kilowatt-hours – five times as much as the old turbine. In future, a total of over 120 million kilowatt-hours of electricity will be produced annually around Gollenberg. That is enough to power around 45,000 households.
