ENTSO-E works closely with the European Commission and is the backbone of the European electricity market countries, 15 have electricity mixes that include nuclear. Coverage of demand by nuclear generation was 24% in 2018, broadly unchanged from a year earlier (+0.7%).
Nuclear generation rose in France and, to a lesser extent, in the Czech Republic, due to greater availability of the nuclear fleets in those countries. Conversely, it contracted sharply in Great Britain, Sweden and Spain.
