On this week’s episode of #TruthtoPower, IntelStor's Founder & CEO, Philip Totaro showcases the latest operations and maintenance cost forecast, and how OEMs, ISPs and asset operators can determine how much they can expect to spend on component repairs.

In 2025, the #windenergy industry is poised to spend more than $2.92 billion on wind turbine repairs in the USA. Blades contribute the most at 37% of the overall, and blades now total more than $1 billion in annual cost.

Lightning damage is the largest cost center, with more than $255.7 million in repairs being undertaken in 2025. That is poised to escalate to more than $333 million by the end of 2034.

Blade root failures are now the second most expensive repair for wind turbines, with more than $222.3 million in annual costs. Root insert separation is a well- known issue on certain makes and models.

For turbines which are in the 1 – 2 MW class, lightning damage is the number 1 issue. Looking at the 2 – 3 MW class, they have more incurred annual cost from fatigue failure in the root as a larger blade repair issue than lightning damage based on data for the 2025 installed base.
