Aerones is bringing robotics and AI to one of the most physically demanding jobs in renewable energy: maintaining wind turbines. Founded in 2015 by Dainis Kruze and Janis Putrams and based in Latvia, the company developed a fleet of robots and drones that climb, inspect, and service turbine blades and towers. The key shift is that human technicians no longer need to rope-access hundreds of meters in the air; instead they control and monitor AI-assisted robotic tools from the safety of a ground vehicle.
The robots handle inspection and maintenance tasks across the turbine, with AI used to analyze captured imagery, detect blade damage and defects, and guide repair work. This combination of robotic actuation and AI-driven analysis aims to make wind operations and maintenance (O&M) faster, safer, and more consistent than traditional manual methods, while reducing the downtime that eats into a turbine's energy output and revenue.
The impact is measured in clean energy and safety. Aerones reports that since 2020 it has enabled nearly 400,000 MWh of additional clean electricity and helped avoid roughly 165,000 tonnes of CO2 emissions, while servicing over 10,000 turbines annually in more than 30 countries. As the installed base of wind capacity ages, demand for efficient, automated maintenance is growing, positioning Aerones in a structurally expanding market.
In June 2025, Aerones raised USD 62 million (around EUR 54 million) co-led by Activate Capital and S2G Investments, with participation from Carbon Equity, Overlap Holdings, and existing investors including Lightrock, Blume Equity, Metaplanet, Change Ventures, and Extantia. The funding supports R&D for its AI-driven solutions and scaling of robotics manufacturing. Aerones has also secured EU grant support to produce and deploy turbine-repair robots, reinforcing its role in Europe's clean-energy infrastructure.
