One of the first Advanced Nuclear Power Plants (NPPs), the BWRX-300 Small Modular Reactor (SMR) will commence operation in 2027 and should become available in the UK by 2030.
This is South Kyle Windfarm:
And this is the BWRX-300 Advanced NPP
For the South Kyle Windfarm investment, assuming the full 15,768,000 MWh are generated by 2048, the first significant cost is a capital investment content of: £20.29/MWh.
The second significant cost is O&M. As the International Renewable Energy Agency (IRENA) puts it: "...O&M data is not consistently reported, making comparisons difficult...":
Fuel, as is stated frequently, is 'free energy'. The third significant cost is a fuel content of : £0.00/MWh.
Decommissioning cost data for the UK is non-existent. A detailed 2017 report on a USA onshore windfarm works out at $155,613/MW of installed capacity. Add in USA inflation of 4.6% and the 'long term' exchange rate of £1.00 = US$1.15 and the cost for South Kyle is £34.0 million.The fourth and final significant cost is a decommissioning content of £2.16/MWh.
It is then possible to ascertain all of the remaining costs: Fuel fabrication; O&M; waste fund; decommissioning fund - from an analysis of Hinkley Point C npp. All of these costs add up to €23.00/MWh in 2018, requiring factoring in the 2018 € to £ exchange rate and UK inflation to 2020. The remaining significant cost is a 'balancing' investment content of £25.10/MWh
The significant cost total is £29.24/MWh. When applied to 77.36 million MWh is £2.26 billion.
Thinking in terms of a Wholesale Electricity Price of £50.00/MWh, by 2048, after its 25 years lifespan of economical operation, South Kyle will have generated an income of £778.4 million, with significant costs of £678.6 million. That's a potential for dividend payments from earnings of £213.3 million.
