Over its 20 year lifetime, Whitelee will deliver intermittent electricity to the equivalent of 5,976,740 homes.
A 440 MW Rolls-Royce Small Modular Reactor [SMR] is a Pressurised Water Reactor [PWR] with a likely capacity factor of 90% and will 'Last for 60 years'.
Rolls-Royce Small Modular Reactors.
Using 'average annual domestic electricity usage of 4,266 kWh' a single 440 MW SMR will supply 24/7 electricity to 813,165 homes, for 60 years - the equivalent of 48,789,900 homes.
8 Whitelee-sized wind farms would have to built to deliver the same amount of Intermittent Electricity as the 24/7 Electricity from a single Rolls-Royce
440 MW SMR.
Whitelee 1 & 2 cost £600 million + £3.8 million decommissioning.
WindEurope - P. 10: Decommissioning of Windfarms
8 x £603.8 million = £4.830 billion.
Taking the worst case scenario of SMRs having the same cost ratio, as the 3.2 GW Hinkley Point C EPR [£18 billion + £7.2 billion decommissioning/waste storage; handling]
a 440 MW SMR would cost £3.465 billion.
Meaning for the same cost, we could get:
40% More 24/7, Low-Carbon Electricity
from SMRs than the Intermittent, Low-Carbon Electricity from Onshore Wind Farms.
