The last operating Magnox reactor – Wylfa 1 – shut down in December 2015.
One manifestation of the focus on renewables was the conversion of one 645 MWe unit of the Drax coal-fired power plant to burn biomass, mainly imported wood pellets, for a guaranteed power price of £105/MWh.
Hence energy poverty is an issue in the UK (as elsewhere), and in the winter of 2012-13 some 31,000 excess deaths – mostly people over 75 – were reported by the Office of National Statistics, the highest figure since 2008.
Since wind is intermittent, it displaces CCGT power and compromises the economics of that.
Note that in the main capacity figures published, those for wind and solar are adjusted to allow for intermittency, by a factor of 0.43 for wind and 0.17 for solar PV, hence 'declared net capacity' (DNC) – “the nominal maximum capability of a generating set to supply electricity to consumers”.
The 78.3 GWe total above is thus less than the sum of the individual actual capacities.
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.
