How to find EYA estimates for a wind turbine ?

[bharathrajad]

In the examples, for the gap analysis, eya estimates are used for the analysis. I have doubt on how to calculate these estimates that are used in the example calculation for la haute wind farm. Please do share any resources, documentation for this calculation. I currently have the general wind turbine specification and raw scada data.

# Define EYA data (we are fabricating these data as an example)
eya_estimates = dict(
    aep=16.46,  # AEP (GWh/yr)
    gross_energy=20.0,  # Gross energy (GWh/yr)
    availability_losses=0.04,  # Availability loss (fraction)
    electrical_losses=0.014,  # Electrical loss (Fraction)
    turbine_losses=0.037,  # Turbine performance loss (fraction)
    blade_degradation_losses=0.011,  # Blade degradation loss (fraction)
    wake_losses=0.087,  # Wake loss (fraction))

Hi @bharathrajad, the eya_estimates data are values that should come directly from a consultant-provided (or even the plant owner's version) energy yield assessment (EYA). We don't have access to that data for La Haute Borne, so we simply made the values up. Let me know if you have further questions on this.
