PERFORMANCE CHECK Module

Visualize Performance with Powerful Graphs

• Multiple time-series, radar, seasonal, and diurnal plots

• Sector-based power curves for measured or expected production

• Flexible XY plots (e.g. RPM vs. pitch angle) with color-coded data overlays

• Diagnostic charts: MTBF, MTTR, error loss matrices

Calculate Long-Term Corrected Future Yield

• Generate long-term corrected AEP estimates using historical production and wind index data
  
  
• Reduce AEP uncertainty by up to 50% compared to pre-construction estimates
  
  
• Improve financial forecasting for refinancing, sale negotiations, or purchase assessments

Wind Index Corrected Production (WCP)

Use a wind index correction method to produce a simple yet powerful long-term yield estimate:

• Rely either on 10-min SCADA data, error logs, etc. or on monthly production and availability data.
  
  
• Calculate and normalize production using EMD-WRF or national index datasets
  
  
• Estimate long-term yield, and energy losses

Reduce Risk & Increase Revenue

By understanding when and why turbines underperform, PERFORMANCE CHECK helps you:

• Increase net income by identifying recoverable energy losses
  
  
• Support proactive maintenance decisions based on cost of errors
  
  
• Improve bankability with accurate future yield reports
  
  
• Refine sale and purchase prices with risk-adjusted data
  
  
• Back up your analysis with detailed reports and visual documentation

TR10 Add-on – Certified Post-Construction Analysis

The TR10 add-on is fully integrated in PERFORMANCE CHECK and supports compliance with the German TR10 standard (rev. 0) for post-construction evaluation.

• Evaluate site yield and quality factor for wind turbines in operation
  
  
• Required for EEG 2017 subsidy reassessments in Germany
  
  
• Certified by TÜV SÜD for turbines with >98% availability
  
  
• Generates TR10-compliant reports with full documentation and traceability

Calibrate Flow Models Using Real Production Data

• Use actual SCADA data to calibrate flow models for repowering, expansions, or quality control of pre-construction estimates.

• Load wind data from nacelles, met masts, or mesoscale sources.

• Perform high-resolution comparisons of measured vs. calculated production by:

  • Direction
  • Season
  • Temperature
  • Day/night cycle
  • Turbulence and air density

Tune the model to site-specific climate, increasing the accuracy of future project estimates.
