RES expands Smart Pilot blade inspection software to smaller, lower-cost drones for wind farm operators
RES dropped notable news on October 26: its Smart Pilot turbine blade inspection software now works with smaller, more affordable drones — including the DJI Matrice 4E. That means wind farm operators can get into automated inspections without committing to expensive specialist hardware, and without sacrificing image quality. The announcement came just ahead of the Brazil Wind Power conference in São Paulo.
RES makes Smart Pilot available on compact consumer-grade drones
The timing was deliberate. RES made the announcement on October 26, one day before Brazil Wind Power kicked off its three-day run (October 27–29) in the same city. The message was clear: automated blade inspection isn’t just for operators with deep pockets and specialized equipment anymore.
Smaller drones like the DJI Matrice 4E cost significantly less than inspection-grade alternatives. RES says they deliver comparable image quality when conditions are decent — so you’re not trading data accuracy for a lower price tag. For operators doing inspections at scale, that’s a real difference in how the math works out.
The company has delivered more than 29GW of renewable energy projects globally and plans to bring more than 26GW of new capacity online over the next five years.
RES operates across 24 countries and holds the title of world’s largest independent renewable energy company. Its Digital Solutions business is the team driving this push to make inspection tech more accessible globally.
How Smart Pilot works and why it was developed
Here’s the problem Smart Pilot was built to solve. Before it existed, inspecting a turbine’s three blades meant stopping the turbine three separate times — one stop, one flight, per blade. That’s a lot of downtime for what’s essentially a data collection task.
RES’s Digital Solutions team launched Smart Pilot in June specifically to fix that. The software automates the whole inspection within a single turbine stop, swapping three separate flights for one coordinated automated sequence. Then in September, they went a step further: Smart Pilot 3 eliminated the need to stop the turbine at all during a full three-blade inspection.
The consistent thread throughout each iteration has been reliable, repeatable data capture across sites. Operators need blade condition data they can actually trust — for maintenance planning, asset life extension, and keeping long-term costs under control.
Inspection times cut to 25 minutes; fleets of 1,200 turbines stand to save 500+ operating hours
The numbers are worth a closer look. Smart Pilot 3 completes a full three-blade inspection of a G97 turbine in just 25 minutes, down from a previous standard of 50 to 70 minutes. That’s 30 to 40 minutes shaved off per turbine compared to competing solutions — not just compared to the old manual process.
A single inspection crew can now cover more than 10 turbines in a day. Across a fleet of nearly 1,200 turbines, that adds up to at least 500 recovered operating hours. Those aren’t marginal efficiency gains — they’re the kind of numbers that reshape how operators plan and budget their entire maintenance season.
There’s a secondary benefit worth noting. Because the rotor only needs to be positioned once, the approach works better on turbines stopped from the nacelle and on sites running in low-wind conditions, where multiple stops would be especially disruptive.
Deployment model: Standard hardware, remote training, global scalability
Smart Pilot runs on standard drone hardware. No proprietary equipment required — which matters for operators who already have inspection teams and existing kit in the field. You don’t have to replace what you’ve got.
Training happens remotely, and RES says teams are operational within half a day. That’s a low barrier to entry, especially for operators managing assets across multiple sites or regions who can’t afford long onboarding cycles. The whole model is designed to scale without creating new equipment dependencies.
Rea Meisinger, Vice President of Digital Blades at RES, put it this way: the value isn’t in any single feature. It’s in how automation, reduced downtime, and high-quality data capture come together on hardware that inspection teams already know how to fly. Consistent data across sites also supports better long-term planning — when blade data looks the same regardless of which crew collected it or which turbine it came from, it becomes genuinely useful for forecasting maintenance costs over time.
Context: Growing industry pressure to cut turbine O&M costs
Wind farm operators are under real pressure to bring O&M costs down. Turbine downtime is expensive, and blade inspections — necessary as they are — have historically eaten up a significant chunk of the O&M calendar.
RES Group has a clear view of this challenge. As a service provider managing more than 45GW of renewable assets, it sees inspection inefficiencies play out at scale across many different sites and operator types. The company has delivered more than 29GW of renewable energy projects globally and plans to bring more than 26GW of new capacity online over the next five years.
What this means for wind farm operators
Smart Pilot now runs on smaller, lower-cost drones, finishes full three-blade inspections in as little as 25 minutes, and produces consistent data useful for long-term asset planning. It works on standard hardware and trains teams remotely in half a day. Across a large fleet, the time savings alone add up to hundreds of recovered operating hours per inspection cycle.
Brazil Wind Power gives RES a regional stage to show Latin American operators what the technology can do — a market where cost-effective inspection tools carry particular weight. Expanding to compact drones like the DJI Matrice 4E is a direct response to where that market is: operators who want automated inspection capability but need it to fit within tighter equipment budgets.
