Cofrentes

What Cofrentes does

Central Nuclear de Cofrentes is a single-site boiling water reactor (BWR) nuclear power plant located in the municipality of Cofrentes, province of Valencia, Spain, at the confluence of the Júcar and Cabriel rivers. The plant began commercial operations in 1984 and is operated by Iberdrola Generación Nuclear, S.A. (Sociedad Unipersonal), a wholly-owned subsidiary of the Iberdrola Group headquartered in Bilbao. With an installed electrical capacity of 1,092 MWe, Cofrentes is the largest reactor in the Spanish nuclear fleet by installed power. In 2025 the facility generated 7,958 million kWh, supplying more than 52% of the electricity consumed in the Valencian Community and meeting the equivalent residential demand of over two million households, while avoiding approximately three million tonnes of CO2 emissions annually.

The facility operates under continuous oversight from Spain's Consejo de Seguridad Nuclear (CSN) and holds EMAS environmental management and AENOR quality certifications. Its core service is baseload nuclear electricity generation sold into the Spanish regional grid, with no direct end-customer billing relationship. Supporting operational functions include scheduled fuel reload outages (the 25th was initiated in September 2025 with a €27 million investment and mobilization of over 1,200 professionals), nuclear safety systems, environmental and radiological monitoring, and a public information center. Distribution of generated electricity is handled through Iberdrola group-level grid infrastructure rather than by the plant entity itself. Headcount is reported in the 1,001–5,000 range, consistent with a continuously staffed industrial nuclear site, and revenue is not disclosed at the plant level — financial results are reported only at the parent Iberdrola Generación Nuclear and consolidated Iberdrola Group levels.
