TEQs would much to reduce demand too.

Even a ‘tame’ (I hesitate on that word because the TEQ scheme is already extremely simple and benign) version, just confined to electricity, would help - but will cannot be introduced as long as electricity remains Thatcherised.

off peak tariffs have been a failure for 50 years. The supply companies are allowed to gouge a much higher tariff in the day making it uneconomic for practical use. They had a shrinking non standardised window of cheap hours instead of the true 9 pm - 6am off-peak demand.

Indeed a very considerable challenge!

When you tot it all up and figure in it all having to be done whilst maintaining a 24/7 supply, it will come to a pretty huge investment. This means that the current cost comparisons being made between say offshore wind and nuclear are very misleading.

It probably would turn into as great a cost overrun nightmare as nuclear so there is the question as to who would be willing to bankroll all this complex new infrastructure? Even significantly altering the load duration profile of the UK itself would be a very challenging project and not for the faint hearted. Leading on such a project would have as many political as practical challenges.

Then "Plan B" is currently scarcely even being considered. Now where have I heard that one?

Shortening the working day, which was supposed to be one of the advantages of computerisation, would help and allow spreading of the load, both on the grid and on the transport infrastructure. Spread load means lower peaks and less capacity needed.

Cottam coal burning power station in Nottinghamshire is to close earlier than expected in September this year.

That represents a loss of 2Gw, or about 4% of peak demand before next winter.
Good news for the environment, but of concern from the energy security point of view.

This power station opened in the late 1960s and is therefore far beyond the originally intended 30 year design life.

Operation has been uneconomic for some years, and the power plant would probably have already been closed without receiving payments under the relatively new "capacity market".
This was a grant/subsidy/market led payment intended to keep open otherwise loss making power plants.
It was NOT a direct subsidy towards the actual cost per unit generated, but it was a payment towards the costs of keeping capacity available in case of need.

The power station will close when these payments cease at the end of September this year.
