When an onshore wind turbine is out of order it generates major costs for the owner or operator. This cost is even greater when it comes to offshore turbines. As such, good money can be made offering continuous, smart monitoring of the turbines, enabling maintenance and service before the blades stop spinning.
For years, Danish supplier Gram & Juhl has been in the business of measuring wind turbine strain and monitoring service needs on the installations. The company has seen a vast improvement in earnings in recent years, and in the annual report for the fiscal year 2015/2016, published in November, the company booked earnings before taxes of DKK 27 million (EUR 3.6 million) on a gross profit of DKK 39.6 million. Earnings before taxes were just DKK 16 million in the previous year.
