GE Vernova to supply three wind turbines for German project

Key Takeaways

• Order size: 3 × GE Vernova 5.5 MW on‑shore turbines (total 16.5 MW) for the Schlotberg‑Jüchsen wind farm.
• Service term: 20‑year long‑term service contract, guaranteeing performance through 2047.
• Delivery schedule: First turbine arrives August 2027; full commissioning targeted for December 2027.
• Cumulative capacity: Stadtwerke Heidenheim’s GE Vernova fleet reaches 74 MW, marking the sixth joint project.
• Strategic fit: Reinforces Germany’s 2030 renewable target of 80 GW on‑shore wind and showcases GE Vernova’s “workhorse” design philosophy.

Overview

GE Vernova, the wind‑energy arm of General Electric, has finalized a supply agreement with municipal utility Stadtwerke Heidenheim AG to install three of its 5.5 MW, 158‑metre rotor‑diameter on‑shore turbines at the Schlotberg‑Jüchsen site in Baden‑Württemberg. The deal also bundles a 20‑year service package, aligning with Germany’s aggressive decarbonisation roadmap and the EU’s 2030 clean‑energy objectives.

Project Details

The turbines will be sited on a 2.5 km² parcel with average wind speeds of 7.5 m s⁻¹ at hub height, delivering an estimated capacity factor of 32 %—typical for German low‑to‑medium‑wind regimes.

Technical Specs of the 5.5 MW Turbine

• Rotor diameter: 158 m (blade tip speed up to 80 m s⁻¹)
• Hub height options: 110 m, 130 m, 150 m (project selected 130 m)
• Generator type: Direct‑drive permanent‑magnet synchronous machine, rated 5.5 MW, 6 kV output
• Cut‑in / rated / cut‑out wind speeds: 3 m s⁻¹ / 12 m s⁻¹ / 25 m s⁻¹
• Control system: GE Vernova Intelligent Control Suite with predictive analytics for blade pitch and yaw.
• Noise level: ≤ 42 dB(A) at 1 km, complying with EU Directive 2009/28/EC.

These specifications reflect GE Vernova’s “workhorse” strategy: standardized, mass‑produced platforms that reduce capital cost (≈ €1.2 M per MW) and simplify supply‑chain logistics.

Service Agreement Highlights

The 20‑year O&M contract covers:

1. Predictive maintenance using GE’s Digital Wind Farm analytics, reducing unplanned downtime by an estimated 15 %.
2. Component replacement for critical wear items (gearbox, blades, pitch system) on a “life‑extension” schedule.
3. Performance guarantees of ≥ 95 % availability during the first 10 years, with step‑down clauses thereafter.

Such a long‑term commitment mitigates financial risk for Stadtwerke Heidenheim and aligns with typical German utility procurement models that favor stable, predictable cash flows.

Strategic Implications

• German renewable targets: The addition of 16.5 MW pushes the nation closer to its 2030 on‑shore wind goal of 80 GW, contributing roughly 0.02 % of the target.
• GE Vernova market share: This order marks the sixth collaboration with the Heidenheim utility, expanding GE’s installed base in Germany to 74 MW—approximately 0.09 % of national on‑shore capacity.
• Industrialization advantage: By leveraging a single turbine model across multiple sites, GE reduces engineering change orders, shortens lead times, and achieves economies of scale that translate into lower levelized cost of electricity (LCOE) for the buyer.
