The transmission line monopoly is such a cash cow that really doesn't make a lot of sense. For the life of me I can't figure out why utility poles don't have wireless communication such that when one node loses power, the previous one kills power to the downed line (which in theory should happen faster than it takes for the line to fall to the ground and start a fire). Once those lines are modernized, the potential for profit is enormous. It doesn't make any financial sense to give up such a rare monopoly.
