The basic energy problem can't be fixed in the short or medium term. It doesn't matter who owns the transmission networks, and shuffling the ownership of the generating facilities can't help. In the medium term, the only answer to the current problem is for consumers to use less electricity. There is no short-term pleasant solution to the power problem. Worse, there is the short-term financial crisis, which has the dynamics of a credit crunch or a run on the banks.
Utilities buy power on credit.
The power shipped today is paid for later. When a buyer's credit-worthiness is called into question, suppliers get worried and ask for higher prices or faster payment to offset the risk of not being paid. Because retail prices are frozen, rising wholesale prices make it even less likely that the utilities can pay their bills. And that, in turn, makes even more suppliers think twice about supplying power to the state. Falling confidence leads to less credit, which leads to more defaults, which further reduces confidence, and so on.
