HOVIK, Norway — DNV has completed a pilot development of ReWind, a digital service to support wind turbine decommissioning.
ReWind takes data provided by the user to automatically produce a decommissioning plan, including where and how the turbine blades can be recycled.
The pilot, which took place between June and October last year, had seven clients providing data on 55 power projects in seven countries, with a total of 7,830 MW modeled.
Using the service, they were able to save an estimated 1,985 workdays and €680,000 ($733,683) compared to current non-digital solutions, DNV claimed. Among the participants were Ørsted, SSE and Energia.
Presenting a credible decommissioning plan has become mandatory in the bidding process for many wind auctions, DNV added, with a focus on improving the life cycle of turbines.
At present, decommissioned wind turbines are often buried underground. The WindEurope association estimates that 25,000 metric tons of wind turbine blades will face recycling by 2025 and 52,000 metric tons by 2030.
Input from ReWind’s users has led to an expansion of its scope beyond decommissioning to support bidding and re-powering, extending services to offshore projects, and improving detail in turbine modeling and cost calculation.
DNV is now looking to expand development beyond the pilot.
