While the interviewer drew the comparison between the UK and US he did not compare to Germany (50% cheaper than UK) who use coal and gas, along side their underperforming wind and solar. While Milliband is correct that gas sets the wholesale price of electricity 98% of the time, offshore windfarms receive the wholesale price £74/MWh plus a further £110/MWh subsidy if they receive ROCs (pre 2019 windfarms) or a guaranteed price under the CfD auction which is £85/MWh for the 2024 auction.
There is then the cost of backup and also the cost of building transmission lines from North Sea to UK population and industrial centres. The inconvenient truth is that the actual cost of electricty generation (set by gas and including carbon tax) is now between 25-30% of the cost charged to industrial and domestic consumers with subsidies, distributor and transmission costs making up the majority of the bill. Pre renewables the cost of generation was about 1/2 of the bill.
Uk uses the marginal cost pricing mechanism which means while gas provides less than 30% of UK electricty on average, it sets the price almost 100% and all providers get the highest price bid in each 30 minute auction. GAs has a low capital cost but high operating costs, renewables are the opposite. Why Milliband does not decouple renewables from the price of gas given the wind and solar operators get a fixed price for 15 years is beyond logic.
