For 5, add in that the new grid capacity is years behind schedule, and the existing grid capacity needs to come offline because it's decrepit, and you also have a policy to connect new sources immediately

It leads to a lot of telling new sources to dump their energy, and paying them to dump their energy, while simultaneously paying old gas generators (nearer the demand) to fire up. All for the want of more grid capacity.
