U.S. wind farm owners are expected to spend over $40 billion on O&M over the next 10 years, and the average age of the North American wind fleet rise from 5.5 years in 2015 to 7 years in 2020, and to 14 years in 2030. Along with that, equipment maintenance and operating costs are increasing significantly, leading operators to focus on performance optimization and cost management.
