I agree with the sentiment but its a bit misplaced here. The energy industry in the UK is still heavily regulated and the government do intervene a lot. The main thrust of this has been to push renewables and nuclear to combat climate change. And the response of National Grid has been to plan for that. For example in planning connections for offshore wind, building interconnectors and incentivising backup capacity. They have a good record in maintaining supply and are well funded.

The trouble is that much of our backup depended on gas and interconnectors. Gas has been effected by the war. The interconnector capacity by French nuclear problems. Those nuclear problems have exasperated gas supply problems.

There are steps the government could have taken. In hindsight maybe we should have kept more coal stations available. And gas storage should have been maintained. And we definitely should have built out more onshore wind. But I don't think the system is mismanaged. And we are probably better placed than much of mainland Europe for this winter. We did build some massive offshore windfarms.
