I would assume Quaid realizes that there is NO ONE GRID. Power transmission is broken up into little fiefdoms run by separate utilities which install, repair, and maintain their own geographical grids - no one else's.
In one sense, it makes the US vulnerable to area/regional breakdowns. From another POV, it also means there is no one national grid that FERC (the government agency that regulates energy companies) itself maintains/protects.
Your local utility almost always has 'reciprocal' agreements with other utilities within reasonable geographic distance. But PG&E in Northern CA, for example, is not going to have a reciprocal agreement with a utility in the state of New Hampshire.
The longer the distance electricity travels, the more energy it loses. This is why many utilities are increasing the number of independent substations, which also has the benefit of reducing the # of people affected when something goes wrong. This way, each geographical 'piece' is proportionately smaller than using fewer but bigger substations, where if something goes wrong, far more people are affected because the area covered was so much greater.
