666,667 East Midlands Population Reject 777 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, every hour of every day 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 equates to a continual average supply of 17,325,571 W of intermittent electricity. This will supply all of the electricity to 29,168 people.

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.

And Finally:
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 output from 
1,865 x 2 MW wind turbines.

So that's 2.4 x £2,258 million:
£5,419 million.

Intermittent Electricity From UK Solar PV Costs 3.78X More Than Nuclear !

There isn't a decent sized solar farm in the UK where the information is available on both cost and electricity generated.

Turn to France and we've got it all:

Calculating the Output of a 300 MW Plant in the UK: 

2012: 1,736 MW delivered 1,328 GWh
So 300 MW would deliver 229.5 GWh

2013: 2,822 MW delivered 2,015 GWh
So 300 MW would deliver 214.2 GWh

2014: 5,228 MW delivered 3,931 GWh
So 300 MW would deliver 225.6 GWh

  2015: 8,915 MW delivered 7,556 GWh
So 300 MW would deliver 254.3 GWh
Statistics Section - Table
Average of 229.5 + 214.2 + 225.6 + 254.3
 = 230.9 GWh/year

Reasonable Life Expectancy of a Solar Array to fall to 80% efficiency - 30 years     Source

The average over 30 years of delivery would be 90% of 
the 230.9 average value: 230.9 x 0.9 = 207.8 GWh/year

Delivery over 30 year Life Expectancy = 6.234 TWh

Exchange Rate 2014: GBP/USD - 1.6$ to the £     Source

So 2014 cost of 300 MW UK Plant = £281.25 million
Comparative Data: Hinkley Point C Nuclear Power Plant

Source 1 - Page 15          Source 2

Delivery over 60 year Life Expectancy = 1,513.7 TWh

1,513.7 ÷ 6.234 = 242.8
242 Cestas-sized Solar Parks would have to be built
to deliver the same amount of electricity !

242 x 281,250,000 = 68,062,500,000
242 Cestas-sized Solar Parks would cost £68 billion !

£68 billion ÷ £18 billion = 3.78

For the same capital expenditure nuclear power will deliver nearly 
4X more 24/7 electricity 
than the intermittent electricity delivered by Solar Parks
242 x 2.5 = 605
242 Solar Parks would cover 605 square kilometres.

Solar Parks just about covering the 
Pembrokeshire Coast National Park !

Kilgallioch - Here We Go Again - Twice The Price Of Nuclear!

Once the programme is completed, in 2017 this will be the UK’s third largest onshore wind farm, with 96 wind turbines with a generating capacity of up to 239 MW, the capacity of the wind farm will be enough to power the equivalent of 130,000 households per year.

A bit of simple arithmetic:
"...annual UK average domestic household consumption is 3,994kWh..."
"...Most wind turbines should last for about 25 years with normal inspection and maintenance..."
130,000 homes x 3,994 kWh = 0.51922 TWh/year.
0.51922 TWh/year x 25 year = 12.98 TWh
of intermittent electricity!

But Hinkley Point C nuclear power plant rated at 3.2 GW, operating at 90% capacity factor, with a design life of 60 years, delivers 1,513.7 TWh
of 24/7 electricity!

116 Kilgalliock-sized wind farms would need to be built to deliver the same amount of [intermittent] electricity as the [24/7] electricity delivered by HPC.
116 wind farms x £300 million = £34.8 billion.
That's HPC + 93%

116 of these GREEN power plants:
coupled with ISSUES:
"...Apart from water, peat bogs are largely composed of huge volumes of saturated, undecayed plants. A single hectare typically contains more than 5000 tonnes of carbon, ten times more than a typical hectare of forest. But any disturbance leads to lower water levels and to the peat drying, oxidising and releasing its carbon, says biochemist Mike Hall of the Cumbria Wildlife Trust.

The bog can decompose for hundreds of metres round every turbine, potentially releasing millions of tonnes of carbon. The process is slow, but frequently unstoppable, Hall says. So many wind farms may eventually emit more carbon than an equivalent coal-fired power station..."

Then there's LAND USE:
116 Kilgalliochs at 32 square kilometres each
= 3,712 square kilometres.
