Repowering and reliability in wind farms in the U.S.: the Green Pastures case

31 / 03 / 2026

At JASO Elevation Systems, we continue to strengthen our presence in the North American wind sector through the development and implementation of robust, safe lifting solutions designed for long-term performan

One of the most representative projects within this strategy is the Green Pastures wind farm, located in Texas (USA). In this project, 100 GW25NA model lifts have been installed in T92 AW3000 wind turbines, featuring 92-meter steel towers. This initiative is part of a repowering process, in which previous systems—affected by structural issues caused by ladder fatigue—have been replaced.

Green Pastures project was developed in collaboration with Nordex USA and is currently operated by Acciona Energía USA, with JASO providing Acciona Energía with technical support since 2025.

Technology that makes the difference

Our rack and pinion lifting systems are designed to meet the demanding requirements of the wind energy sector, delivering significant improvements in safety, efficiency, and durability.

Key advantages include optimized access and maintenance times within the tower, enhanced safety conditions for technicians, and reliable operation in demanding environments. In addition, these systems are engineered to align their service life with that of the wind turbine, contributing to more efficient and sustainable operations.

Currently, over 1,450 of our GA25, GA27, and GW25NA units are installed across North America.
