Electricity price predictions
@batpred You are correct, for new customers. If I switch to Flux in April, when I want to switch back to Go in October, the rates I get might be different and even higher than 9.5 p.
Not a big deal, but as Outgoing Octopus has dropped to 12 p, and given that our South West facing array produces good chunk from 4 pm to 7 pm, thought moving to Flux is probably a good move. But, if that means we would have to pay higher rates when the HP is running whole day and EV needs more charging due to lower efficiency and pre entry climate control, then probably this move for summer is not worth it. I might do some modelling to see at what rates would it tip over the balance. At least Octopus makes such analysis easy by letting you download half-hourly consumption and export data.

Thanks for sharing your thinking. It made me think how many factors need to be considered to optimise the tariffs when you have so much renewable technology..

Posted by: @jamespaElectricity retailers offer fixed price deals. By agreeing the purchase price in advance they can manage the risks. Electricity generators probably buy fuel in advance as well (obviously not renewables). All this trading creates a market for data centres.
I assumed you were joking here.
Hence my joke about a data centre in planning consultation stage: the backup diesel generators are so large that they led some people to start questioning whether they would just be used in regular tests.
Clearly industrial electricity prices have been rising very significantly in the UK, according to DESNZ:
Could we say that the UK market protects consumers better than in the US, where domestic prices rose by 6% in 2025?
