I find this hard to believe.

I have seen many other sources state that wind power, due to the peaks and valleys of production by such an inconsistent source, could never be more than 20% of total supply for any grid. Also, even the 20% figure was theoretical, as even relatively large wind-energy producers such as Netherlands and Denmark have not even come close to that figure.

Any experts out there who can solve this?

Denmark produces about 20% of their power with wind.
