The Ascó nuclear power plant is located in the town of Ascó, in the district of Ribera d'Ebre in the province of Tarragona. Cooling for the two groups is provided by the Ebro River.

Authorisation for construction of unit I was granted by what was then the Ministry of Industry and Energy (MINER) in 1974, and the other unit was authorised in 1975. The right to use the cooling water was awarded in 1977. After the operation permit was granted by MINER in 1982, the first unit was connected to the grid in 1983, followed by the second in 1985.

The integration of the site into its surroundigs was achieved by building confidence in the reliability and safety of its operation over the years

The integration of the site into its surroundings was achieved by building confidence in the reliability and safety of its operation over the years, as well as by collaborating in activities of general interest promoted by local cultural and sports associations.
The land around the plant (and owned by it) has been used to cultivate vines, olives, fruit, etc.

In order to make the plant’s activities and nuclear power in general more accesible to society, in November 2011 Ascó opened a new interactive information center that is open to the public.
