It would probably require some kind of public bailout (which we are already getting in part), much like the banks received from defaulting/going under.
In reality it is a private company selling a product at market prices (actually below because of a government enforced price cap) that the public now don't like. Most costs in our lives are based around market prices, and we accept them, the difference here is elec/gas along with food are one of the unavoidable essentials, so you're on the hook for it regardless, and so is the government, as freezing and starvation is not a good look. I think they need to get ahead of the game for when autumn and winter arrives, and also think hard about energy security and the approach to energy saving AND production in the short to mid term.
I think, as a policy, it could be a vote winner (not that I care about that, doing the right thing is more important
) as when an issue is in sharp focus, it resonates with people.
Too add, I also believe there needs to be some collective, Europe wide, thinking about this coming Winter. Many places could literally be caught cold.
