In 2015 the France link ran at 81% capacity and the Netherlands one at 91%.
Per capita UK electricity consumption was about 4700 k Wh in 2014.
The corresponding increases in annual demand range from 15 to 45 TWh.
UK generating capacity (Department for Business, Energy & Industrial Strategy data 27/7/17) at the end of 2016 was 78.3 GWe (68.4 GWe with grid access), comprising 16.7 GWe conventional steam, 31.8 GWe CCGT, 9.5 GWe nuclear, 16.2 GWe wind (gross), 11.9 solar (gross), 4.3 GWe hydro including pumped storage, 5.7 GWe bioenergy and wastes. Load factors in 2016 were 78% for nuclear, 49% for CCGT and 38% for other thermal plants (including coal – 16.5%), 27.9% for wind (23.7% onshore and 36% offshore), and 11% for solar.
The last operating Magnox reactor – Wylfa 1 – shut down in December 2015.
In 2013-14, 18.6 TWh was involved and 67.2 million certificates were issued or redeemed, 57% for wind, 17% for biomass and 12.6% for hydro.
However, in April 2014 the second unit converted to biomass was denied similar investment contract support, leaving it to recoup costs from Renewables Obligation Certificates (at 0.9 ROC/MWh; the average ROC price in May 2014 was about £41.70) plus the wholesale power price – about £50/MWh. However, the government offered an investment contract with price guarantee for the third Drax unit (see also UK section in the Energy Subsidies information paper).
Each Drax unit burning biomass uses about 4 million tonnes of imported wood pellets per year.
There are plans for a new fleet of nuclear power stations, including at Wylfa and Moorside.
It also means exploring new opportunities like small modular reactors, which hold the promise of low cost, low carbon energy." This was reinforced in July 2017 with the National Grid’s update of Future Energy Scenarios.
In 2016, 336 TWh of electricity was produced in the UK (Department for Business, Energy & Industrial Strategy data 27/7/17) and 324 TWh was supplied to the grid.
