2026 & 2025: A Strong Start Across Europe 

As we move through April 2026, WPO continues to accelerate its momentum across Europe – and the year is already shaping up to be a powerful demonstration of our technical expertise and commitment to excellence. 

We are kicking off new End‑of‑Warranty campaign in Sweden, where our teams will be inspecting Vestas V150 turbines through a full 360° technical scope: from Technical Audits and Drone Blade Inspections to Gearbox Video-endoscopy, Oil & Grease Analysis and Transformer inspection. A complete, high‑value diagnostic designed to secure the long‑term performance of our clients’ assets. 

Right after Sweden, we head to Finland, where our engineers will carry out an enhanced inspection program on Vestas V162 turbines. In addition to the standard EoW scope, the campaign will also include Safety System Testing, Tower Bolt Spot Checks and Yaw Ring Gear Inspections – reinforcing our ability to provide deep, technical insight on the industry’s latest and largest turbine platforms. 

Across the North Sea, the UK will soon welcome our specialists for an End‑of‑Maintenance mission on Nordex N100 turbines, ensuring operators have full clarity on asset condition before entering a new operational phase. 

And of course, France remains one of our strongest markets, with numerous End‑of‑Warranty campaigns underway on N117, V136 and V150 turbines, confirming WPO’s position as a trusted partner for wind farm owners and asset managers. 

Looking back at 2025, WPO delivered an exceptional year of activity: 

✅ Over 60 wind and solar sites inspected across France 

✅ More than 120 wind turbines audited for commissioning, End‑of‑Warranty and asset‑management support 

✅ Close to 950 MWp of solar assets benefiting from our technical advisory services 

Internationally, our teams operated across 20 sites in the UK, Lithuania, Greece, Ireland, Germany, Sweden and Norway – delivering more than 115 technical audits, alongside numerous gearbox video‑endoscopies and blade inspection campaigns. 

Our core audit services include: 

• End of Warranty Inspections: Identify hidden defects before warranties expire and secure corrective actions. 

• End of Maintenance contract Inspections: Assess asset condition at contract closure and ensure all maintenance obligations have been properly fulfilled.
