From August 2015 renewables no longer receive climate change levy exemption certificates, saving £3.9 billion over five years.
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.
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.
Drax is seen to be the biggest single loser from the removal of the Climate Change Levy exemption for renewables in August 2015.
Three of the six Drax units are now converted to biomass and in 2016 produced 12.7 TWh, accounting for 65% of the plant’s output.
Per capita UK electricity consumption was about 4650 k Wh in 2015.
In 2015, 45% of the UK's gas was from domestic production, primarily in the North Sea.
Currently, there are 15 operating reactors in the UK totalling 9.5 GWe capacity.
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 the light of projected peak demand of 85 GWe by 2050, its main scenario called for 14.5 GWe of new nuclear plant online by 2035, and nuclear supplying 31% of demand in 2050.
Different scenarios concerning electric vehicles increase peak demand by 6 GWe, 11 GWe or 18 GWe by 2050 depending on when the majority are charged, and assuming 7 k W charging (30 amps).
