With WindESCo you'll move beyond data visualization to make actionable improvements to your turbines. Here are just a few of the optimizations our customers have implemented to improve their asset performance. 

Example Finds

• Rated Power Issue

  

  High-frequency data detected converter fan issues that caused high temperatures. By replacing the fan the turbine increased production 2.4% and recovered $32,000 in annual revenue for the customer. 

• Yaw Misalignment

  

  WindESCo found 6° of yaw misalignment on a turbine that caused 1.1% loss for the turbine and .6% loss for the plant. Through parameter changes, the customer recovered $4,300 per year for the turbine and $320,000 per year for the farm. 

• Unexpected Curtailment

  

  Analysis of 10-minute data revealed unexpected curtailment that was not associated with a known event. WindESCo determined that an incorrect parameter had been applied to the site causing a 5% AEP impact to the farm. 

• Pitch Optimization Issue

  

  WindESCo detected non-optimal minimum pitch setting which was adjusted by 0.5°. This improved AEP for the turbine by 0.9% resulting in $131,375 increase annually. 

• Startup Issue

  

  High-frequency data analysis found multiple failed attempts to startup on a particular turbine. After adjusting parameters, the turbine operated as expected adding 1% AEP and $42,000/year to the plant.

• Torque Gain Inconsistency

  

  10-minute data analysis detected the torque gain/curve was inconsistent across peers. By correcting parameter values, 0.8% AEP was gained resulting in $50,000 in additional revenue. The turbine was also protected from risk of blade damage associated with Torque issues.
