Funny enough, this is why you see wind farms where there is a decent prevailing wind.

The biggest issue is usually our lack of capacity to store/transmit. They shut of some turbines because they over produce for the Network capacity.

You have to fire up the gas generators either way to fill in the gaps.

Scheduled nuclear downtime isnt any greener than the a slow wind day.

But downtime of a turbine only affects one turbine. The rest can carry on as normal and generate power. With nuclear you can lose 1000MW all at once.
