Electricity in most networks is bid on usually just two or three hours into the future, for 30min windows of electricity. (Biding starts up to a day or two before, but the auctions usually only close and hour or two before the 30min block starts). It’s pretty easy to predict the amount of wind two or three hours into the future, wind doesn’t just “stop” without any sort of warning. (At least not when you’re dealing with wind over 100s of square KM in the middle of an ocean). So selling renewables into the grid isn’t that hard, even across grids. But you might not be able to command the same premium that a more “reliable” source could.
