As usual, this analysis seems to focus on the supply side without appreciation for the demand side. If there were a 100% conversion to wind power, side effects related to distribution and availability factor would be obvious, but since it's only a partial conversion, it seems as if these costs are overlooked.

Some demand adjustments are inexpensive such as scheduling. Others are more expensive, such as the distribution network. Others are really expensive but accounted for differently, such as household battery storage. If you have x% penetration by wind compared to y%, these costs change.

It doesn't seem right to hold the demand side of the equation constant while trying to optimize the supply side...
