666,667 East Midlands Population Reject 1,003 x 2 MW Wind Turbines And Choose 1 Small Modular Reactor [SMR]

A single Rolls - Royce 440 MW Small Modular Reactor has a design life of 60 years and a availability factor of 90%. On average, it will deliver 396,000,000 W of 24/7, low-carbon electricity daily, for 60 years.
Every hour of every day, each man, woman and child in the UK uses 594 W of electricity - not just for our direct use but 'our content' of the electricity used by industry, commerce, business, schools, hospitals and everything that provides our wonderful way of life. So:
Small Modular Reactors - once in a lifetime opportunity for the UK
Keadby 68 MW Onshore Wind Farm
Keadby - Sustainability Impact Report
Supplying 38,000 homes is the 'starting point' that windfarm operators publicise. But wind turbine performance deteriorates by 1.6% p.a. In the last year of its 25 year lifespan, it will only be supplying 26,650 homes. On average, over 25 years, that's 29,444 homes.
Conclusion: 1.6% annual degradation.

This equates to a continual average delivery of 13,424,582 W of intermittent electricity, enough to supply electricity to 22,600 people.
To supply 666,667 people would require 29.5 Keadby-sized wind farms - a total of 1,003 x 2 MW wind turbines at a cost of £2,915 million.

The site size for 1,003 x 2 MW wind turbines would need to be 265.5 sq km.

And that's not the end of the story:

To provide electricity for the 60 year design life of the SMR, after 25 years a 2nd batch of 1,003 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. Only then would intermittent wind power match the 24/7 nuclear power from an SMR. That's the intermittent output from 2,407 x 2 MW wind turbines.

That's a cost of 2.4 x £2,915 million:    £6,996 million.
The most appropriate costing for a R-R SMRs is to use the 'Current Study (adjusted-mature designs)' rate of £5,000/kW

Added to this must be the Hinkley Point C ratio of £7.3 billion, for decommissioning, waste handling and storage, against the £18 billion capital cost.  
In total, a 440 MW SMR would cost:  £3,092 million.

Onshore Wind Turbines cost 2.26X more than SMRs !


  1. YESSSSS, proud to be in East Midlands, albeit by only 800 metres, but it still counts as "one in my back yard".

  2. Very interesting could you send me links where I could find more infomation?
    Great post :-)

    1. The links to Rolls-Royce and Keadby are there in 'off-red' small print.

      The 594 W per person is from the total electricity generated in a year divided by (365 x 24) and then divided by the population.

  3. Wind energy does not word, its a figment of feeble imagination

  4. The Current Conservatives' Greg Clark and his cronies might just as well all be Greenpeace plants, intent on destroying through his current Energy Policy, our values and way of life.
    His so called renewable energy fiasco, backed up by demand management and Smart meters intended to limit our use, should bring to an abrupt end, - his political career.
