Gross production comprised 72 TWh (21%) nuclear, 143 TWh (42%) from gas, 31 TWh (9%) from coal (less than half the 2015 figure, due to doubling of the carbon price floor to £18), 1.8 TWh from oil, and 24.5% from renewables: 37.4 TWh (11%) from wind, 10.4 TWh from solar PV, 8 TWh hydro and pumped storage, 30 TWh from biofuels including waste.Increased renewables generation capacity was balanced by less favourable weather conditions for solar and wind generation. There is a 2000 MW high-voltage DC connection with France and a 1000 MW one with the Netherlands; also a 1000 MW one with Belgium is under construction for 2018, and the 1400 MW Northconnect link over 750 km between Scotland and Norway will begin construction in 20 commissioning, partly funded by the EU.The company is working on the development of four 300 MWe open cycle gas turbine units, intending to commit when “the UK capacity market clears at a price that provides a robust underpinning for such investment.” Two could be online by 2021, and the other two by 2024.In November 2015 the government articulated new policy priorities for UK energy, involving possibly phasing out coal-fired generation without CO2 abatement in 2025, building new gas-fired plants, and much greater reliance on nuclear power and offshore wind to grapple with “a legacy of ageing, often unreliable plant” and undue reliance on coal.
The remaining 17% was imported in liquefied form on tankers, mainly from Qatar.The energy secretary said: "Opponents of nuclear misread the science. The challenge, as with other low carbon technologies, is to deliver nuclear power which is low cost as well. “We are dealing with a legacy of under-investment and with Hinkley Point C planning to start generating in the mid-2020s, this is already changing.It is imperative we do not make the mistakes of the past and just build one nuclear power station.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.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.UK energy policy since the 2008 Energy Act through to July 2015 has been built around reducing CO emissions rather than security of supply or cost.In 2010-11 the price of renewable energy certificates doubled the price or electricity from those sources – an increasing proportion, including imports – more than one-quarter.Net electricity imports – mostly nuclear – were 17.5 TWh, comprising 9.7 TWh from France, 7.3 TWh from the Netherlands, and 0.5 TWh net was exported to Ireland. A further 2000 MW connection to Normandy was approved in September 2016 to enable the import of French nuclear power from 2022.In 2015 the France link ran at 81% capacity and the Netherlands one at 91%.
