I hope the incentives for cleaner energy continue to stack up. With the surge in demand from AI surely productivity will be more tightly coupled with energy usage and cost.

(at the rate it takes to deploy transmission, might as well start dropping TBMs in the ground and let them grind towards each other from interconnect landings, potentially faster than the approval grind, complaints from locals about land use and right of ways, etc)
Conversely, standing charges ARE regionalised - because that does advantage the SE of England. Oh well!

TL;DR - Until new interconnectors between Scotland and England are finished in 2029, there will be significant curtailment of Scottish wind power which increases costs.
This is also an interesting site for seeing curtailment per wind farm - https://windtable.co.uk/data?farm=Seagreen
Ideas crop up like generating hydrogen with the curtailed energy or maybe at least in Winter, use it for heat generation. The problem would seem to be the capex and the inverse of intermittency being the problem for them in utilising that energy, i.e. waiting for curtailment.
At least with available hydro you can pump water back up hill using a reliable and cheap tech.
Charging batteries definitely seems like part of the solution and electricity tariffs that adapt to wholesale costs on a shorter time basis help incentivise it. There are times over weekends/holidays where the wholesale price enters negative territory, essentially paying you to charge your battery.
Electrolysing hydrogen to burn is inefficient vs that kind of thing but at least acts as a battery itself, though there's costs/problems in storing it.
And the general problem of how long do you need to store energy vs what the weather forecast may be.
It seems like it's not a solved problem and it'd be exciting to move towards a point where it is. Hard to believe in the 50's they thought nuclear would solve everything and would be "too cheap to meter"
OVO[1] and Octopus[2] offer smart charging tariffs that give EV owners reduced electricity rates.
The usual caveat is you can only benefit if you can install a charger and park near that charger. Still, based on this 2021 article [3] 65% of UK homes have at least one off street space, so the potential for a majority of homes to smart charge is there.
To extend the benefit of cheap smart charging to more people, it would be good to see legislation that makes it easier for leaseholders and renters to require the installation of a smart charger where technically possible.

Oh no we messed up nuclear oops sorry made it very expensive. Pay up
Oops sorry we messed up transmission pay up
Oops sorry we let people get into huge energy debt pls pay off their debt in your bill...
