During the time of energy crisis why would the integrated energy market be the highest priority? Is it more important to trade, or to keep economy running utilizing whatever local advantages available?
I mean, whenever electricity is being exported at high cost, that high cost is an indication that this other place has it even worse; and blocking trade would make electricity cheaper at the exporting place, but cause a larger spike (and possibly even blackouts with the associated economic disruption) at the importing place and also remove the economic incentives to increase surplus production at places who can do it cheaper than others.
Energy is the economy, and the failure of an integrated energy market means the failure of so much more.
