Lots of probs with existing grid . Certain routes are already overloaded/congested, building new ones is not as easy because of land acquisition costs compared to the past. Repairing, upgrading and maintaining old routes to handle new loads raises costs of moving electrons to your factory etc. One hurricane or blizzard can shut a route down so redundant routes have to be built. People just under estimate how complex things have become.
