= = = This seems like the sort of problem that could be much more logically and less painfully solved by breaking out the (more or less constant, at least within a given size class and geographic area) grid hookup cost and the per-KW/h price for electricity as separate items on the bill. = = =
Problem comes in when an entire region gets three day of hot, cloud-covered, calm weather. Then everyone expect "the grid" to produce the power that the panels and wind turbines aren't. The result where this has happened in the Midwest and Texas regions over the last two years has been spot market power prices going up to $1000/MWh but no power being available.
I personally think the US needs a lot more solar and at least a fair amount more wind, but there are real problems that need to be worked out. And the Chicago School - which doesn't acknowledge the existence of market failure - doesn't have answer for those problems.
