Repowering brings more power to Minfeld
The project
In the district of Germersheim, the repowering project in Minfeld, which was completed in 2026, marked the connection to the grid of another key initiative in the region’s energy transition. Of the original five older wind turbines, four were replaced with two new, more powerful turbines as part of the repowering project. The fifth turbine, a V90 model, remains in operation. The two new six-megawatt wind turbines together supply climate-friendly electricity to over 30,000 households. The site thus makes a significant contribution to the region’s sustainable energy supply and increases output by a factor of 2.5 compared with the old turbines. The project was implemented in close cooperation with MVV, whilst planning and development were carried out by JUWI.
In what is known as ‘repowering’, older wind turbines are replaced with modern, high-performance and therefore more efficient turbines. This gives the energy transition a new boost whilst ensuring that the number of wind turbines does not rise to astronomical levels.
Turning old into progress
The repowering project in Minfeld clearly demonstrates how existing sites can be upgraded using modern technology without requiring additional land. With a hub height of 169 metres and a rotor diameter of 162 metres, the new turbines generate significantly more electricity than the four older turbines dating from 2004. These technical improvements increase the wind farm’s annual energy yield by a factor of 2.5. Minfeld thus serves as an example of how repowering boosts a wind farm’s performance and makes a significant contribution to the regional energy supply.
Repowering projects
Minfeld is one of the JUWI Group’s most recent repowering projects. Since its first project in the Rhein-Hunsrück district in 2010, JUWI has completed 40 repowering projects, replacing 135 older turbines with 121 modern wind turbines. Despite the lower number of turbines, the total capacity rose from 131 to 443 megawatts, representing an average increase in capacity by a factor of 3.4. Due to the greater hub heights of modern turbines, the actual energy yield is usually even significantly higher.
