What I struggle with is the difference it would make in the energy generation sector with its present pricing structures especially how it would necessarily lead to lower prices whilst the UK is still heavily dependent on gas-fired power stations for electricity generation to pad out the supply provided by non-carbons (wind, solar, hydro, nuclear etc). Throw in the marginal price model determining what all the producers are paid except those that supply under a cfd (contracts for difference) and I struggle even more.
The yearly cfd scheme auction (AR5) failed in 2023 and the AR6 process is underway with contracts to be awarded later this summer. Even one of the offshore AR4 contracts collapsed Vattenfall Norfolk Farm Project
Possibly a higher maximum price for offshore wind in AR6 (66% above the disasterous AR5 figure) will create an avalanche of bids when the results are announced.
Rambling I know but where would Great British Energy fit into this? If they are going to be truely independent, they would have to tender for the same allocations as the likes of Vattenfall did in AR4. This is all assuming that the current generation remuneration structures remain in situ.
