Can someone explain why nuclear is a good option in regards to cost? The proposed EDF sites seem very expensive and why have the UK government offered what appears to be 'very'generous unit prices for energy production. £20bn or so seems expensive and decontamination costs will probably sting as well.
IIRC the cost for the proposed EDF deal isn't that much higher than some of the "green" feed in tarrifs, and is based on the price 10+ years in the future so whilst it's expensive compared to now, in 10 years time the average price per unit will only have gone up anyway.
From what I remember some of the green tarriffs had people getting paid something like 2-3 times the retail cost per unit (so something like 5+ times the cost per unit from normal production), whilst the proposed EDF deal is only twice the current wholesale average, and to be honest we need that capacity ASAP, we are running low on spare capacity on the current grid (we've been retiring older stations faster than we've been building new ones), and if the price of oil and gas go up much the average price of conventional power will go up a lot.
