At the moment those costs are hidden in the average cost of a kWh.
Speak for yourself. My electric co-op charges me an explicit infrastructure charge, itemized separately from my usage-based power consumption bill. It's a flat rate. It's 50 cents per day. And before you fluff up and fume and fuss, that is a sustainable price. It has not changed in over a decade. It is also the correct price. It's a co-op. I'm a part owner. I attend the annual meetings when I can, and always read the financial statements they publish every year. I know every detail of the financial workings of the co-op. I can go to their home office and read the contracts, if it suits me. I'm an owner.
50 cents per meter per day is sufficient to keep an award-winning grid in good repair. And this is a rural grid too, with a relatively low density of meters per mile of wire. State law forbids co-ops to operate inside of incorporated city limits, one of the finer examples of crony capitalism to be found. Only the for-profit corporations are allowed to serve cities, with their much higher density of meters per mile of wire. So not only is my co-op sustainably servicing my house for 50 cents per day, they're doing it while lugging power across mostly empty rural counties. If they were allowed to serve all of the residents, that fee would go down, since the average number of meters per mile would go up.
No, the government does not need to take them over. The customers do. They simply won't be profitable anymore. Power will still be delivered, the lights will still stay on, average outage frequency and duration will go down (I have numbers to prove it), and fat cats will no longer get fatter at the expense of the poor and middle class. Oh what a crying shame.
No, it's not a free lunch. But it is lunch money.
