Project: 50-MW wind farm, Location: Sweden
SgurrEnergy was commissioned by a wind farm operator to investigate the performance of their wind farm using the SgurrOptimiser forestry service.
Setting the scene
SgurrEnergy was commissioned by a wind farm operator to investigate the performance of their wind farm using the SgurrOptimiser forestry service. The wind farm was located within a forested area.
Evaluating the situation
The investigation began with SgurrEnergy’s Measurement Team deploying a Galion Lidar on site to assess the wind flow in the affected area. The Analysis Team then analysed the data gathered and subsequent modeling from this campaign and identified the forest areas impacting on the wind farm’s performance.
The results
The forestry surrounding the wind farm creates a complex wind flow. This disturbed wind flow can reduce the lifespan and output of the wind turbine generators. The results showed that if forestry restructuring works were undertaken the potential annual energy yield increase could be in the region of 3%.
The solution
Detailed discussions were held with the forest management company and the restructuring options were agreed within the context for forest sustainability criteria. The restructuring works are currently underway and by targeting pockets of the forest for restructuring, a commercial balance can be struck benefiting both the wind farm operator and the forest owner. Ongoing consultation will take place between the forest owner and SgurrEnergy to complete all of the required felling within the annual forest management plans.
What we learned
This exercise confirmed that an integrated approach using state-of-the-art lidar measurement technology coupled with computational modeling expertise delivers substantial value for wind farm owners through targeted forestry restructuring. Working within forestry management guidelines, and conducting extensive consultation with forestry authorities are also essential to successful delivery.
