Keadby 68 MW Onshore Wind Farm
Keadby - Sustainability Impact Report
To supply 666,667 people would require almost 23 Keadby-sized wind farms - a total of 777 x 2 MW wind turbines at a cost of £2,258 million.
The site size for 777 x 2 MW wind turbines would need to be 205 sq km.
To provide electricity for the 60 year design life of the SMR, after 25 years a 2nd batch of 777 x 2 MW wind turbines would have to be built and then a 3rd batch would have to deliver for 15 years [40% of its lifespan] before intermittent wind power matched the 24/7 nuclear power from an SMR. That's the intermittent output from
1,865 x 2 MW wind turbines.
So that's 2.4 x £2,258 million: £5,419 million.
The most expensive form of Pressurised Water Reactor, the the 3,200 MW EPR at Hinkley Point, has a capital cost of £18 Billion + a 'delayed' cost of £7.2 billion for decommissioning and waste handling and storage. That works out at £7,875 million/MW.
At the same rate in £/MW for capital cost, decommissioning, waste handling and storage, a 440 MW SMR would cost: £3,465 million.
Onshore Wind Turbines cost 56% more than SMRs !
