Nuclear Generation : 7.1GW

Recently replacing Sweden in the number 10 spot , nuclear energy currently accounts for 22 % of Spain ’ s electricity . The country has an installed capacity of 7.1GW , generated by seven reactors .

Nuclear plants are currently essential to the country ' s energy grid needs and ministers have thus lifted limits to their operational lifespans . In 2020 and 2021 , six of the country ' s seven reactors renewed their licences . All of these would expire before 2035 – the deadline for the Spanish Government ' s planned phaseout of nuclear power .

Nuclear Generation : 8.9GW

Coming in at number 9 is the UK , with a combined net nuclear energy capacity of 8.9GW from 13 operable nuclear reactors . The country generated a total of 51TWh of nuclear energy in 2019 – 15.6 % of the UK ’ s total electricity output .

Expected to open in June of 2027 , construction has started on two new nuclear reactors , Hinkley Point C1 and Hinkley Point C2 , which will supply low-carbon electricity for 6 million homes .

Approximately half of its existing nuclear power reactors will be retired by 2035 .
