There are two individual people who happen to work for the TVA charged with individual crimes which don't implicate the organization.
There's a lawsuit from profit-seeking companies charging the TVA contracts are too long (perhaps true but there's no mention of profit).
Then there's a scandal about the TVA reacting badly to safety whistle blowers (bad! But also no clear link to "profiteering")
I think a more useful model is to look at what "the organization" does (as opposed to the people who work for it). For instance, Enron's business strategy relied on breaking the law. PG&E has been unable (or unwilling) to maintain its infrastructure to a level where it is safe to operate year round. These things existed outside of any individual crimes committed by employees (and it is useful to differentiate between individuals who are committing crimes in service of organization goals v.s. only for private benefit).

The solution to one chunk of the government running mad and then handing lots of money to some other chunk of the government to try to chase after them would... uh... probably produce a world fairly similar to what we live in, actually. Which isn't a solution.
Regardless, constantly changing the goal posts with no significant costs to the ones doing the changing is a problem for any funding mechanism.
In fact, we tried your proposal at scale. Nearly every developed country privatized electricity generation in the 1980s. Many countries, like India, still have state-owned power companies. If they were better, we would know.
Crucially, China still has 67% of generation from fossil fuel sources vs. the US at 61%.
They are footing an entirely different kind of bill instead, paid with an entirely different kind of currency.
Instead of paying for a nuclear plant, regardless by what mechanism, they are living with continued use of coal and gas, or simply not enough capacity to meet the upcoming needs of things like wider adoption of EVs.
