Wind
Turbine Power Calculator
Do not operate the form until
this page and its programme have loaded completely. If you are
too fast, the programme will complain about missing data, and
you'll have to click reload. Note1: 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 to the
South 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.
 You
may experiment by changing the figures in the example below.
You can fill in any box, except the result boxes marked with
an asterisk (*). After changing data, use the tab key, click
the Calculate button, or click anywhere on the page outside the
field you have updated to see the results. Click on the question
marks for help. (If a plot windows disappears, it is probably
hidden behind this window).
