GE Vernova has secured an agreement with German municipal utility Stadtwerke Heidenheim AG to supply three onshore wind turbines for the Schlotberg-Jüchsen wind farm in Germany. Announced on November 9, 2026, the contract covers three 5.5 MW-158m machines, adding 16.5 MW of rated generation capacity. It also includes a 20-year service agreement, extending the partnership beyond equipment delivery and installation into long-term turbine support.
The turbines belong to GE Vernova’s 5.5 MW platform and feature a rotor diameter of 158 metres. The model designation 5.5 MW-158m refers to its rated power and rotor diameter, respectively. The larger rotor is designed to capture wind across a wider swept area, supporting energy production under suitable site conditions. The agreement does not disclose the expected annual electricity generation or the project's estimated investment.
Manufacturing will take place at GE Vernova’s Salzbergen facility in Germany. The factory is part of the company’s domestic industrial network, which it identifies as comprising 13 locations across the country. Local production is a notable element of the order, connecting the project to Germany-based manufacturing and supply-chain operations rather than relying solely on imported finished turbines. GE Vernova describes its approach as a workhorse strategy based on standardised machines designed for repeatable manufacturing and deployment.
The agreement is the sixth wind project undertaken by GE Vernova and Stadtwerke Heidenheim. Once the three new turbines are installed, the utility’s fleet of GE Vernova machines in Germany is expected to reach 74 MW of installed capacity. The company has scheduled the start of turbine deliveries for August 2027, with commissioning planned for December 2027. These are projected milestones rather than completed project dates.
The project also carries a delivery-related dimension. Stadtwerke Heidenheim’s Head of Renewable Energy, Raphael Kaim, said the development had experienced unexpected delays and faced statutory deadlines. The utility therefore prioritised a supplier able to meet the required construction and commissioning schedule. GE Vernova’s delivery timetable and manufacturing presence in Germany were cited by the utility as important factors in moving the project forward.
GE Vernova has positioned the order within its broader strategy of supplying standardised onshore turbine platforms. The company says its workhorse technology has accumulated more than 38 million operating hours across over 2,100 units globally. It also reports that more than 59,000 of its turbines are operating worldwide. These are company-reported fleet figures and provide context for its stated emphasis on established technology and repeatable project execution.
The Schlotberg-Jüchsen contract adds to GE Vernova’s German onshore wind business through a combination of locally manufactured equipment and a long-term maintenance commitment. For Stadtwerke Heidenheim, the next milestones are turbine deliveries in August 2027 and commissioning in December. The project’s progress will depend on meeting this schedule following the delays identified by the utility.
