Wind turbine cleaning for asset owners
You set the maintenance budget and you carry the production that is not generated while a machine is down. This service exists so those two things stop pulling against each other.
The problem on your desk
Your machines need cleaning and you know it. What does not add up is the full cost of doing it the traditional way: four to five days of downtime per turbine, plus day rates for personnel certified to work at height, plus rigging and de-rigging the access.
Multiplied across the machines in a campaign, that stops looking like maintenance and starts looking like capital expenditure. And like all capital expenditure, it competes. Often it loses.
What the drone changes
One working day per turbine instead of four or five. Nobody at height. And 75-80 % lower cost and lost production against the traditional method, combining the labour you do not pay for and the production you do not forgo.
Cleaning fits back inside a normal maintenance window, without having to block out the annual outage calendar.
What we are not going to tell you
We are not going to give you a percentage of production recovered by cleaning. Several figures circulate in the sector, they cite each other, and none arrives with a measurement we can verify at a specific Spanish site. If someone gives you one to two decimal places, ask them where it comes from.
What we can stand behind is the operational side: how long it takes, what gets cleaned, with what equipment, under what permits, and what evidence each machine is handed over with.
How to start without committing
If you have an older fleet and are not sure where to begin, a drone inspection is cheaper than a blind campaign and gives you the real condition of every machine as a photographic report. That is what decides which machines get cleaned this year and which can wait.
And if you already know, three data points fix a price: number of turbines, location and rotor diameter. Minimum order is 4 machines per campaign.

Frequently asked questions
Do you work directly with owners, or only through the O&M provider?
Both. If you contract directly, we coordinate with whoever operates the site. If you would rather it sat inside your O&M provider’s contract, we also work as a subcontractor.
What about contractor coordination paperwork?
We take it on: we supply health and safety documentation, insurance and the individual file for every pilot, on whatever platform you use. We have already cleared a major utility’s prequalification process, so the file is built.
Can I start with a single site?
Yes. The minimum is 4 turbines per campaign, not a minimum number of sites. Starting with one and seeing the result is the most common route.

Three data points are enough: number of turbines, location and rotor diameter. We come back with a fixed price per machine and scope within two working days.
