Cofrentes NPP entered service on October 14, 1984, with an installed power capacity of 992 MWe.

The following two years were dedicated to basic engineering, acquiring the main equipment and securing the construction authorization.

In 1975, the Cofrentes Municipal Council issued the building permit and business activity licence, and the Ministry of Industry authorized construction.

[3] The plant project[4] began in March 1973, when contracts were drawn up with General Electric Co. to supply the reactor, turbogenerator (turbine and generator) and the first load of fuel.

The reactor, a BWR-6 type, uses slightly enriched uranium which fissions generate energy as heat.

[7] In 2013, Cofrentes Nuclear Power Plant generated 8,325 billion kilowatt hours (kWh), equivalent to approximately 4.9% of Spain's national electrical production (under the ordinary system) and 14.7% of the energy produced from nuclear sources.

The Plant has been running at 87% of its total capacity, operating with generator coupled to the energy grid for 7,801 hours a year.
