For UK specific electricity costs I'd recommend looking at https://www.electricitybills.uk/

The UK is a grid that is adding lots of renewables and building some nuclear plants, so the site provides good data around the costs for the added transmission, storage and subsidies (for both renewables and nuclear) needed for a renewables heavy grid supplemented with nuclear.
