Every year, the 215 wind turbines of the 539 MW Whitelee Onshore Wind Farm will deliver intermittent electricity to 298,837 UK homes from a 78 sq km site on ancient peat bog.
The capacity of Whitelee would have to increase by 37.3% to supply the same number of homes as a 220 MW SMR. That would take the number of turbines up to 295, with a rating of 740 MW on a site expanded to 107 sq km.
Best Estimate of SMR Overnight Cost to Compare to the Overnight Cost of Onshore Wind Farms:
- A 220 MW SMR should cost £1.1 billion.
- Whitelee Onshore Wind Farm costs £600 million, but increasing capacity by 37.3% would take that up to £824 million.
- The SMR will deliver 24/7, low-carbon electricity for 60 years.
- Whitelee will deliver low-carbon electricity for only 20 years.
- A 2nd wind farm would have to be built - that's 40 years.
- A 3rd would have to be built before the same amount of electricity was delivered as the single SMR.
- A single 220 MW SMR delivers as much 24/7 electricity as the intermittent electricity delivered by 3 x 295 wind turbines - that's 885 wind turbines - with an installed capacity of 2,220 MW
- Equivalent Onshore Wind Farms would 3 x £824 million = £2.472 billion.
- An Onshore Wind Farms cost 2.25X more to build than a single SMR.
- An Onshore Wind Farm installation, of 295 wind turbines, occupies 1,338X more area.
