Operating capacity of nuclear power stations in the United Kingdom (UK) 2018

Operating capacity of nuclear power plants in the United Kingdom (UK) in 2018 (in megawatts)

by Ian Tiseo, last edited Jun 21, 2019
Operating capacity of nuclear power stations in the United Kingdom (UK) 2018 Of the UK’s 15 nuclear power plants, the operating capacity was highest at Heysham II-1 and Heysham II-2 in 2018, with a combined total of 1,220 megawatts. This was slightly more than was recorded at the Sizwell B nuclear plant.
Electricity generation

Nuclear energy plays an important role in the UK’s generation of electricity. Whilst its shares have dropped from approximately 30 percent seen in 1997, nuclear power generated 21 percent of electricity in 2017. This decline can be partially explained by the increase in renewable sources. Electricity generation from renewables overtook nuclear power for the first time in 2014 and has remained ahead since. Despite this overall decrease, projections for the year 2035 show electricity generation from nuclear sources increasing significantly to 104 terawatt hours.

Nuclear power demand expected to increase

  Since 2010, nuclear electricity consumption has seen little change, peaking at 15.6 million metric tons of oil equivalent in 2011, and falling to a low of 13.9 in 2014. However, it is anticipated that by 2035 the projected demand for nuclear energy will rise to 26 million metric tons of oil equivalent.
