I think even with the HVDC interconnects going in as quick as they can, I think from memory we will get 2GW in 2026 and 4GW extra in 2030. By the time that's happened there will be even more RE in the North so just laying cable cant solve the problem by itself. The majority of wind projects are still going in where they shouldn't be (various reasons), we have all the bits we need for a lovely zero carbon energy system (but need to be careful not the screw this up as we go, I do not think we will get the storage projected) - especially as the various turbines under FIT and ROC expire. I am all for the full whack node locational pricing. (Scotland will say otherwise since it would effectively blunt any further RE projects there, unless onshore is greenlit.)Joeboy wrote: ↑Thu Jan 12, 2023 9:42 pmThank you, i will read the links in the morning, much appreciated.

In this context where generators and consumers don't care where the energy is coming from and going to (prices are independent in the UK) the NGESO pick up the bits and deliver the physical reality and have the final say in keeping the lights on. The NGESO look after the balancing mechanism that fixes the issues that crop up that would put the grid out of balance across the whole network.
Its meant to be a very light touch mechanism but in 2022 they have had to intervene with over 50% of generation in the UK. The balancing kinda has to happen in hour before the power is going to be used and this is a super costly way to optimise the system. I wont get into curtailment process but the base problem is that you generate RE, get paid, get paid to turn off, then pay again to generate the demand far away with gas since you cant get the RE to the location or store it.
A much more elegant solution would be to use location as the market, placing more responsibility on generators and consumers and actually worry about where the energy is coming from and where it’s going. This style of system is used in NZ, bits of US and Canada.
So the idea is you split the UK energy market into lots of small nodes and allowing prices to develop independently in each node. This would mean much lower power prices in places with high generation and low demand (Scotland, North) and much higher prices in places with lots of demand and not much generation (South).
This would provide an excellent incentive for generators, who might finally battle the NIMBYIsm of the South East and build more there. Youd also hopefully see energy-intensive industries move North, closer to existing RE.
NGESO like this idea and want to start to dramatically get it going in 5 years under the "Net Zero Market Reform Phase 3 Conclusions" - Catapult & Octopus estimate this could save £30 billion within 10 years. Other people in the market hate the idea as they remember the last rejig in 2000s.

Octopus "fan club" is a pseudo-version of it. Archy at Carbonchain has several more pages on it.
https://www.nationalgrideso.com/documen ... 6/download - NGESO made a big case for it too, reform is a hot topic.
