Gas-fired backup plant ‘turn’ this intermittent electricity into usable 24/7/365 electricity. The overnight capital cost (OCC) + fuel cost totalled £31.93/MWh. This electricity is NOT ZERO-CARBON!

21 UK SMR nuclear power plants (NPPs) will generate 79 TWh per annum for their design life of 60 years, with near 100% certainty of an economical life-extension to 80 Years.

The OCC will be £37.8 billion, equating to £0.63 billion/year.

In respect of the fuel cost per unit of electricity generated, little variation is likely to be experienced between ‘Big Nuclear’ power plants and SMRs. Figures of [US] $6.50/MWh for Singe-Units and $6.06/MWh for Multi-Units average out at $6.28/MWh. At a 5 year average of $1.3 to the £1.00:

The cost of fuel is £4.83/MWh.

£0.63/MWh + £4.83/MWh = £5.46/MWh

Note: THIS IS…


At what overnight capital cost (OCC) and Fuel cost per MWh?

Today, gas-fired plants backup wind and solar power plants (WASPPs).
At the moment, other energy storage technologies, such as Li-ion batteries, are ruled out on the grounds of cost and environmental impact.
But will it remain the case when we get to 2050. The use of natural gas will have ‘vanished’ by then and gas-fired generation, will have to be fuelled by greenH2 — if it still remains economical.

The UK’s leading NGO for the wind power industry is ‘renewableUK’
From their website, 13,796 MW of onshore wind and 10,415 MW of offshore wind have generated 66,045,516 MWh of electricity over…


All fossil fuel burning will ‘disappear’ from electricity generation by 2050. It has to be greenH2-fuelled gas turbines as the least-worst option!!!

For 1 year from 01 January 2020, WASPPs generated at an average power of 9.01 GW (See Infographics below). This represents the actual power level required for despatchable, 24/7/365 electricity, totalling 78,927,600 MWh over the 365 days of the year. Over a 7 day period, that equates to a total of 1,513,680 MWh.

For 7 days, from 04 November 2020, WASPPs generated at an average power of 4.56 GW, supplying 781,200 MWh over the period.

The difference between the average and lowest generation is 732,480 MWh. So, to raise the low figure for the generation from WASPPs that occurred over…


Mark P Mills pulls the plug on Intermittent Electricity from ‘Renewables’

At 11:49 “…There is no such thing as Renewable Energy..……..all energy is free…”
Meaning: The energy locked inside uranium is as freely available to humanity as the energy locked inside the wind and in sunlight.

It only becomes useful to us when we: (i) Procure the rights to land or seabed to ‘mine’ that energy (ii) Build machines to extract the energy and turn it into electricity or heat.

ALL MACHINES WEAR OUT. There is nothing renewable about machines wearing out. They are, in fact, all REBUILDABLES!


"...according to the Climate Change Committee (CCC), UK low-carbon investment each year will have to increase from around £10 billion in 2020 to around £50 billion by 2030, continuing at around that level through to 2050..."

That extra £40 billion is to decarbonise all sectors.

I make it £31.83 billion [part cost] just to decarbonise the electricity sector following the CCC's recommendations.

But because of the 25/30 years lifespans of WASPPs, the plants being built now will have to be decommissioned and new plants built to replace them.

The £31.83 billion per year, will carry on every year - FOREVER!!!

Advanced nuclear power plants would reduce that figure to £8.41 billion per year:

"...the incredibly cheap cost of wind and solar..."

The reason greenH2 will happen is it's the only way to solve the INTERMITTENCY PROBLEM and get 24/7/365 electricity from WASPPs.

That's why the Germans have committed €9 billion to greenH2 (including €2 billion going straight to Morocco so they can import greenH2 from there).

Plus. the EU are investing €130 billion in an EU wide GreenH2 infrastructure, involving the conversion of 27,500 km of natural gas network for the distribution of greenH2. I'm sure they would appreciate you letting them know about embrittlement - imagine them not knowing about that!

I've…


Turning the useless electricity from IMPORTED wind and solar power plants (WASPPs) into despatchable (24/7/365) electricity will cost £31.15 billion each and every year, FOREVER!!!!!

Conversely, the 635 TWh/year of despatchable electricity from UK-MANUFACTURED, advanced Nuclear Power Plants (NPPs) will cost just £8.11 billion per year.

Decarbonising the electricity sector means only low-carbon electricity and green hydrogen (greenH2), manufactured from low-carbon electricity, can get the UK to net-zero. Where electricity cannot be used directly or through batteries, greenH2 will decarbonise the rest: the heating, transport and industrial sectors.

But first, electricity generation has to be decarbonised. In 2019, figures from the BEIS show, from a total 323.7 TWh of generation, Coal and Gas generated 133.4 TWh.
Coal and natural gas (NG) have to go! Biomass for the environmental abomination that it is, should go also! …


In pro-nuclear public comment, I feel the time is right to always mention the imminence of the operational dates for 3 SMRs: GE Hitachi's BWRX-300 (2027); NuScale and Rolls-Royce 2029.

Of utmost importance is to get over the fact that SMRs have build programmes down to 2 years: GE Hitachi 24 months; NuScale 3 years; Rolls -Royce 4 years.

These build periods level the playing field with those of wind and solar power plants (WASPPs) and the cost-of-capital that has crucified 'big nuclear' for decades, is utterly negated.

This means that commercial investors can weigh up the relative profitability from…


Just a few days ago, 06 December 2020, for more than 24 hours, the total installed capacity of the UK’s WASPs, hit a combined capacity factor of 1.6%:

On average, over the course of 2019, WASPs generated 13,800 MW of intermittent electricity every hour of every day. This [on average] was enough to power the 27.8 million UK households, with 2.3 MW [on average] going spare.

But this new record sets an all time low for the number of households powered by WASPs — it was down to 1.44 million, which is almost 1 in every 20 of the present…

BWRX-300 SMR: The world’s most cost-effective NPP

The World's #1 Fan of the BWRX-300. The lowest cost/MW nuclear power plant (NPP) that has ever been designed or is ever likely to be designed. Build starts 2024
