hmm, maybe instead the player could control how much power goes to the left and how much power goes to the right. This would eliminate tha problem of important things happening offscreen with no indication, since a failure in power on one side of a grid wouldn't cause a outage on the opposite side of the grid. I just dislike dealing with the fact that building structures next to a generator will take away power from whatever's on the other side, even if the structure you built already gets power from somewhere else.
