The issue is pretty complex, strange. There are three power grids in the continental US. West, East, and Texas. Texas has a given climate pattern where it’s hot, humid, and moderate in the winter. Only few days of chilly. This is why the whole state shuts down and people run in to grab white bread and milk when there is a dusting of snow. All in all, not really that bad, cold wise. As such their utilities and the capacities therein are only capable of flowing energy at the status quo. Then the jet dips way down and Texas gets to feel like Minnesota in December. But unlike Texas, Minnesota is accustomed to it and it’s just a normal winter day. Our homes are built for it, our HVAC systems have the capacity to keep up with it, but most importantly our energy infrastructure is equipped to deal with high demand and low temps. Our windmills still turn happily in -22F ambient. Now, if our organic systems are taxed, or major feed lines are downed, we can pull power from Miami if needed. Just as we can feed Miami if they need it.
Texas, however can’t pull from outside and there system is not equipped to deal with the requirements needed when temps get that low. They are simply not equipped for it. additionally, they can’t pull from elsewhere because, we’ll, they are a closed system.
rambling... this is good scotch.
