France seems to work. They have plenty of nuclear power that is flexible. And you can have other forms of consumption flexibility; otherwise wind and solar are really in trouble.

The AGRs are advanced reactors that use an inert coolant, CO2. In fact they have been designed to cool down quicker than any credible loss of coolant. And have been in service since the 70s, with some slated to go on until 2030.

The article quotes £147/MWh for CCGTs. These look to come from the Electricity Generation Costs 2025 [0] released on the same day as the CfD results. However there is no £147/MWh in Annex A [1]. There is a £145/MWh for CCGT d

Sorry, alignment issue! Probably transport is less troublesome as it has a decent element of demand side response to it (batteries sufficiently large for a couple of days without charging).

Heating from gas is quite peaky (morning and evening heating cycles), whereas heat pumps are best when run low-and-steady. Assuming 2/3 of residential heat demand transitions to heat pumps, and assuming an optimistic COP of 3 in the wo

Transmission in this sense does not include distribution losses (by the DNOs, at lower voltages). 8% in your link. The UK government is now touting datacentre sites with better access to the national grid (transmission network) to avoid the

The big question is how much it will cost. For comparison I believe there is a heat battery in Germany using (atmospheric pressure) liquid water (98 C), 50M EUR for perhaps 20x the thermal storage capacity (versus 20 C water). The use of sa
