ToggleWind energy is one of the world’s leading renewable power sources. But keeping turbines spinning efficiently takes more than strong winds
That’s where O&M, short for Operations and Maintenance, comes into play. It forms the foundation of wind farm performance by ensuring turbines operate safely, reliably, and efficiently throughout their entire lifespan.
In the context of wind energy, O&M refers to the systematic processes that ensure turbines deliver maximum output with minimal risk. For a 100 MW wind farm, efficient O&M can mean the difference between 98% and 90% availability — equivalent to millions in lost revenue annually.
Understanding O&M in Wind Energy
Operations and Maintenance (O&M) covers all the work needed to operate wind turbines and keep them in optimal condition.
This includes daily monitoring, data analysis, preventive care, and repairs when issues occur
O&M costs typically account for 20–25% of a wind farm’s total lifetime expenses, making them one of the largest operational considerations for asset owners.
The goal of O&M is straightforward: to maximise energy output while minimising downtime.
The Core Elements of O&M
Operations
Operations involve managing the daily performance of wind turbines.
This means tracking energy production, adjusting system settings for efficiency, and monitoring environmental conditions that affect performance.
Maintenance
Maintenance ensures that turbines continue to operate safely and effectively over time
It includes scheduled inspections, lubrication, part replacements, and testing of sensors, brakes, and electrical systems
Together, operations and maintenance form a complete ecosystem that keeps wind farms productive and reliable.
Different O&M Strategies
Preventive and Corrective Maintenance
Preventive maintenance focuses on regular checkups and servicing to stop small issues from becoming major failures.
Corrective maintenance is reactive; it happens after a fault occurs.
Both approaches are necessary, but finding the right balance between them helps reduce unplanned downtime and operating costs.
For example, preventive maintenance might involve a scheduled inspection after every 2,000 operating hours, whereas corrective maintenance occurs only after a failure such as a gearbox malfunction or blade crack.
Predictive Maintenance
A growing number of wind farms are now using predictive maintenance, a data-driven method that uses sensors and artificial intelligence to detect issues early.
Instead of waiting for problems, operators can act at the right moment based on data insights
Predictive systems analyse vibration patterns, temperature data, and acoustic signals to identify early-stage anomalies — sometimes weeks before a fault occurs.

Why O&M Matters
Good O&M practices can be the difference between a profitable and an inefficient wind farm.
Even a short outage can lead to significant energy loss, so proactive maintenance directly impacts revenue and performance
It also ensures safety — protecting technicians and preventing mechanical failures that could cause larger issues.
According to IRENA, downtime costs can exceed $2,000 per turbine per day. Effective O&M reduces this risk, extends turbine lifetime, and improves overall energy availability by up to 5%.
By managing turbines efficiently, operators extend equipment life and guarantee consistent energy production.
Technology’s Role in Modern O&M
AI and Remote Monitoring
Artificial intelligence and connected sensor systems have completely changed how maintenance is done
Real-time data collection allows engineers to spot unusual patterns in vibration, temperature, or torque long before a breakdown happens.
AI-powered monitoring systems make it possible to track turbine blades remotely, identify erosion or surface damage, and plan repairs before serious failures occur.
For instance, Werover’s AI-powered blade health monitoring system continuously analyses acoustic data to detect erosion, cracks, or lightning damage long before they impact energy output — reducing maintenance costs and downtime by up to 50%

Automation and Drones
Automation tools and inspection drones have made turbine maintenance faster and safer
Engineers can perform visual inspections without climbing towers, improving accuracy while reducing safety risks and costs.
Drone-based inspections can cut inspection time by 70% and improve image accuracy through AI-assisted analysis. Combined with automated reporting systems, they help teams schedule repairs more efficiently and reduce overall O&M costs.
However, most drone-based inspections are typically conducted only once a year — meaning turbine blades remain unmonitored for the remaining 364 days. This lack of continuous visibility often results in late-stage damage detection, higher repair costs, and unnecessary downtime.
The Future of O&M
The future of Operations and Maintenance is digital
Predictive analytics, robotics, and smart materials are turning wind farms into self-learning systems.
IInstead of reacting to failures, operators will rely on AI to predict, plan, and optimise every stage of turbine performance.
As these technologies mature, O&M will shift from being a cost centre to becoming a strategic advantage that drives sustainability and efficiency.
Conclusion
O&M — Operations and Maintenance — is at the heart of every successful wind farm
It ensures that turbines run smoothly, safely, and efficiently.
As AI and data analytics become standard practice, O&M is transforming from reactive maintenance to intelligent asset management — a crucial step for a net-zero future
With innovations such as Predictive Maintenance and AI-Powered Blade Health Monitoring, companies like Werover are transforming the way the wind industry approaches maintenance
The result is smarter, safer, and more sustainable energy for the future.
