Note 1: Energy output results from calculation programmes like this may differ slightly from the results given by manufacturers.

Note 2: Power curves are found by field measurements which may be uncertain. Therefore these results should be interpreted with great care, as the may be some +/-10 per cent uncertainty in these measurements.

Note 3: Turbine manufacturers may have site specific turbine models available which are not listed here.

Note 4: The site data below was not chosen as being particularly suitable for wind turbines, but was taken directly from the anemometer locations used in the European Wind Atlas. In the case of e.g. Frankfurt (D), one may e.g. find locations on neighbouring hills with twice as high an annual production as you would get at the airport where the anemometer is located. In the case of e.g. Northwestern Ireland, sites on rounded hills in the area may yield 20-25 per cent higher energy output.

Note: This calculator may be used together with the Wind Energy Economics Calculator. If you open the economics calculator from this page, they will both be on screen, and this calculator will automatically feed its energy output result into the economics calculator.
