  Too be fair I Used R.e.f data (Arch anti renewables pro imported dirty fossil fuels lobbby group) for Rocs £1.75 billion (22.5% of which is offshore wind) ,cfd for new nuke as calc by citi group bank and Greenwich university and used by Tom Burke.CCS with deccs data.

Over 30 years at 1.8gw capacity each ,New nuke at £43.52 billion ,CCs Coal at £34 billion?, Old nuclear £16 billion ,offshore wind £11.46 billion ,onshore £6 billion. Making equivalent onshore wind by far the cheapest around 11% of the cost of new nuclear.

C (capacity in gigawatts) x 1000 (converts gigawatts to megawatts) x S (difference between wholesale price and strike price in CfD) x 8760 (hours in a year) x 0.8 (plant availability).

For Hinkley and Sizewell, using the necessary strike price calculated by Peter Atherton of Citi (£166/MWh), compared to a current wholesale price of £51/MWh, and assuming the CfD is for 30 years and the plant runs for 80% of the time the formula then gives:

6.4*1000*30*115*8760*0.8 = £155 billion.

1.8*1000*30*115*8760*0.8 = £43.52 billion for 1.8Gw plant

To be very clear, the total cost to British businesses and householders of a CfD for 30 years that will be necessary to induce EDF to order Hinkley and Sizewell will be £155 billion. This calculation assumes that the reactors will be built on time and to budget, a feat which has so far eluded Areva, EDF’s reactor supplier. If they are not, it will rise.

Present Nuclear

£83 Billion raxpayer funded decommisioning plus £20 billion for deep depository,plus unlimited taxpayer insurance ?(£130 billion for Tepco/Fukishima disaster) ,total £113 billion divided by approx 10Gw = 11.3 billion per GW * 1.8Gw =£20.3 Billion plant

CCS coal? Same CFD calc plus coal injuries and free coal £5 billion?plus competition @ £1 billion

Offshore wind
http://www.ref.org.uk/publications/238-the-probable-cost-of-uk-renewable-electricity-subsidies-2002-2030 (described by Decc as oversimplistic and not including benefits to economy and health)
£1.75 total rocs awarded & expected for 2012 (Ref) for 8Gw ,offshore wind 22.5% of Rocs = £338Million * 30 years = £10.1 billion

 Onshore harder to calc

Rocs half to 75% of offshore rocs ,
Ref calc onshore to receive 0.75 billion for 6.6gw . 6.6/1.8 =27.3% x 0.75 x 30 years = £6.14 billion
