Intriguing design approach, if true :-(

Perhaps more a case that when the wind blows the owners of the windmills
are keen to sell their expensive electrons, but the grid has mostly
contracted in advance to buy cheaper predictable electrons from elsewhere?

Do the windfarms have contracts that force the grid to buy* their
output, similar to solar PV?
