Norwegian utility Statkraft has closed a large investment in wind-turbine-blade-inspector SkySpecs, pushing the fast growing robotics company closer to upscaling its international operations.

Statkraft Ventures together with UL Ventures, Capital Midwest and existing investors closed an $8m financing round for Michigan, US-based SkySpecs.

The investors said SkySpecs helps drive down costs in the sector by making rotor blade inspections more precise and safe, while making operations cheaper compared to traditional methods.
