Of the 34 European Network of Transmission System Operators for Electricity, which has 34 member countries and 41 transmission system operator (TSO) members. Its purpose is to promote important aspects of electricity policy such as security, renewable energy development and the power market. 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.
