Grid-Induced Power Limitation Identified Behind Performance Drop
"Kavaken detected a sharp performance drop in one turbine’s power curve and helped confirm that the issue stemmed from grid-related power limitation, not turbine performance."
The Impact
The Issue
A noticeable decrease in power curve performance was observed on one turbine, diverging from both its historical trend and nearby units. The behavior initially appeared as an unexplained loss in production efficiency.
The Action
Kavaken’s analysis showed that the turbine was generating below expected levels without any mechanical or environmental cause. After further investigation, the operator confirmed that external grid-related power limitation was affecting multiple turbines on site. Once resolved, performance returned to normal, verifying that the loss originated from grid constraints rather than a turbine fault.
