Wind AEP Calculator — Australia
Annual energy production for a turbine in Australia via Weibull statistics (mean 7.8 m/s, k≈2.2).
southern coastal sites in the Roaring Forties influence. The estimator integrates a standard power curve over the Weibull distribution typical of Australia (mean 7.8 m/s at hub, shape k≈2.2) — change the inputs to your met-mast numbers for a site-specific screen.
AEP integrates a standard cubic power curve (cut-in 3, rated 12, cut-out 25 m/s) over the Weibull wind distribution fitted to your mean speed and shape factor. Screening accuracy ±10% — bankable studies need the OEM curve and on-site met data.
Engineering estimate from published standards and typical equipment data. Site conditions, equipment datasheets and measured data govern the real result — confirm with a qualified engineer.

Frequently asked questions
How is annual energy production estimated from mean wind speed?+
Mean speed alone underestimates badly — energy lives in the distribution's gusty tail. The Weibull fit (mean + shape factor k) reconstructs the full speed histogram, and integrating the power curve over it gives AEP within ±10% of professional screening tools.
What is the Weibull shape factor k?+
It describes wind steadiness: k≈1.6–1.9 means gusty/variable (some temperate sites), k≈2 the common default, k≈2.5–3+ remarkably steady trade winds (Brazil's northeast, parts of Tamil Nadu). Same mean speed, different k, can move AEP 10–15%.
What mean wind speed makes a site viable?+
Rough gates at hub height: below 5.5 m/s rarely pencils for grid-scale; 6.5–7.5 m/s is solid; above 8 m/s excellent. Small wind needs the same speeds at far lower hub heights — which is why most residential sites fail (see the small-wind tools for honest math).
Why does the Wind AEP Calculator — Australia differ from my consultant's number?+
Screening vs engineering: this integrates a standardized power curve over fitted statistics; bankable studies use the OEM's exact curve, on-site met-mast data, wake and loss models. Expect ±10% agreement — close enough to rank sites and sanity-check claims, not to finance them.
