NG has the contract for fixing the lines in the region and is the main energy broker, unfortunately.
This is the ultimate problem: having the power lines and the energy broker/provider be the same entity. The power lines are an obvious natural monopoly. The supply of energy across those power lines is not a natural monopoly. The lines should be owned by one company and the power selling/brokerage should be by a different company.
I fear I would then end up with two bills, one covering the cost of the energy I want and another to allow the delivery of that energy to the location I desire...
And because the lines are not owned by the power seller, when an ice storm takes them down I would probably get a bill for my portion of the repair! Yes, they already pass those costs on, but it is spread amongst many more customers. I don't want to see the bill for my exact share of the repair of the circuit that runs from the power source clear to my meter. I could end up paying for work done on a generation station, sub-stations, etc. that are not even in my state.
Utility companies buy and sell power to each other as demand and supply dictate, and their overhead (including normal line maintenance) is factored into the system. Having a third party control distribution would simply add another entity feeding off the revenue stream... that's OK, they can just pass that on to end users and it will be business as usual!
