Calculation method
Calculation method
Expected gross energy (kWh)
Interpolate supplied turbine power curve at wind bins and weight by bin hours; all queried bins must lie inside curve.
Mean power over supplied hours (kW)
Interpolate supplied turbine power curve at wind bins and weight by bin hours; all queried bins must lie inside curve.
Symbols and units
- a
- Wind-speed bins (m/s)
- b
- Hours in each wind bin (hours)
- c
- Power-curve wind speeds (m/s)
- d
- Power-curve output (kW)
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions & limits
Assumptions & limits
- User-supplied measurements and assumptions; Interpolate supplied turbine power curve at wind bins and weight by bin hours; all queried bins must lie inside curve. Supported limits: Finite numeric values bounded to 1e9 magnitude; lists and tables contain 1–100 records unless a stricter bound is stated. Inputs use the units shown. Lists explicitly paired by a method must have matching lengths; independent polynomial coefficient vectors may differ. Respect stated physical, interpolation, policy and computational domain limits.
