Ten-minute SCADA data has served the wind industry well for decades. It is compact, widely available and useful for monitoring production, availability and long-term performance trends. But a wind turbine does not operate in 10-minute increments. Wind conditions change from second to second. Turbine controllers continually adjust operating parameters in response. A great deal can happen during a 10-minute period—and much of that behavior disappears when the data is reduced to

A turbine may be online, free of major alarms and technically available while still producing less power than it could. These losses can persist for months—or even years—without creating the type of obvious fault that triggers an urgent maintenance response. That is why wind asset performance must be evaluated through two complementary lenses: availability and energy performance.
