Deliberately underfunded or mismanaged, maybe. It’s been like this since the 90s at least. But I don’t think they need any intent for a buyout for it to suck. Afaik, there is zero interest from any private buyers for our utilities.
If I had to point to a specific failure, it’s that the rates are set by city council, and raising them is wildly unpopular. Everyone who proposed it loses re-election. We have some of the cheapest power in the world but fat lot of good that does when it’s not on.
They buy most power from TVA, the rate city council controls is the fixed rate markup they charge on top. Our power is $0.07/kwh by the time you pay for it.
