Challenge

Pinpoint the cause of lost yield on a single turbine where SCADA alone did not isolate the issue, and coordinate a fast, evidence-based fix with the OEM/O&M.

Solution

Deployed a nacelle-mounted LiDAR (via Galetech Energy Services) for four weeks to measure free-stream wind direction ahead of the rotor; analysis identified a 4° misalignment. The O&M team corrected yaw alignment; a repeat LiDAR deployment verified resolution.
