Our history

In this section, we have outlined a timeline marking the most important milestones in the history of Cofrentes Nuclear Power Plant (Cofrentes NPP) from its beginnings in 1972 to the present day.

In 1972, the Ministry of Industry, Energy and Tourism granted the Site Approval to construct Cofrentes NPP.

In 1973, contracts were drawn up for:

  • Supplying the reactor, Turbogenerator (turbine and generator) and the first load of fuel with General Electric Co.
  • Engineering work.

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

In 1975, the Cofrentes Municipal Council (*) See explanation  issued the Building Permit and Business Activity Licence, and the Ministry of Industry authorized construction. Soon, the ground broke and the Plant’s foundation was laid.

Toward the end of 1976, the Ministry of Public Works granted the use of waters from the Júcar (*) See explanation  river for future exploitation.

The construction period was marked by the following significant milestones:

  • The reactor’s concrete slab was laid (1976),
  • The hoisting and placement of the vessel (1977),
  • Assembly of the turbogenerator(1978), and
  • The construction of the cooling circuit, including the towers (1979).
  • In 1980, the Ministry of Industry and Energy authorised the transport of the first fuel core and temporary storage of radioactive material in the Plant. Further, the condenser assembly finished, (1980) and work on the reactor pipes began (1981).

In 1982, the Ministry of Industry and Energy extended the Construction Authorization and approved the Prenuclear Testing Programme, thus commencing testing. At the same time, construction was brought to a close and civil works were finished.

1984 is a key year, as the Ministry of Industry and Energy issued the Provisional Operating Permit, thus admitting fuel loading, running nuclear tests and the definitive connection of the Plant to the peninsula’s high voltage power grid, which was executed on 14 October. All these efforts and actions enabled thermal power to reach 50% in October, 75% in November; finally attaining 100% on 18 January of the following year.

In 1986, an extension to the Provisional Operating Permit (POP) was granted, securing since then successive two-year extensions in 1988, 1990, 1992 and 1994; a five-year extension in 1996; a ten-year extension in 2001 and, the last one, in 2011, for a new ten-year extension, until 2021.

Upon the granting of these Operating Permits, and in each one of the aforementioned extensions, a series of Plant operation limits and conditions were established, making these authorizations one of the most important.
