Reply to comment by Barra79 in [OC] Wind Speed Vs Wind Power by Barra79

This one makes a little more sense to me, I would expect max power to be at lower speed than the original Germany based plot, and the decreasing power at high wind speed as they go offline and “park”

OP is the total production in Germany, extremely windy conditions in Hamburg will usually come with less extreme winds elsewhere.

Exactly my point, so it dilutes the data, and gives misleading impression.

Wind turbines derate earliest from 20 m/s and cut out around 30-40 m/s. On this graph it drops off at 14 m/s, so it doesn't fit.

Also I hate seeing powercurves in km/h. Nobody does that in the wind industry.

Point being, the original post did not reflect this behavior at all.

Why not, it's SI units. Everyone (in europe) knows km/h and has a pretty good picture of it, e.g. from driving. So the selected units meets the intended audience.

I hate the "knots" or other measures. They should perhaps switch from BS units to SI units.

Because you're plotting what's called a "powercurve". It's a standard figure in the wind industry, because wind is nearly always measured in m/s or knots.

I've worked with wind turbines for 11 years and made hundreds of powercurves. Never seen anyone use km/h before.
