About us

The completion of the San Esteban II hydroelectric plant in 2013 made the San Esteban (San Estevo) plant the largest hydroelectric complex in Galicia, with a total installed capacity of 451 MW. Located in the Sil river basin, the facility is a pioneer in the region for producing hydroelectric power equivalent to the average annual consumption of more than 600,000 people, almost twice the population of the province of Ourense.

The dam is an essential element in a hydroelectric power plant because of its important function. It is the civil works infrastructure that makes it possible to impound the water that will subsequently drive the turbines of the power plant, generating clean electricity. There are different types of dams, either according to their materials or their mechanisms.

The electricity sector is the best available energy vector to incorporate renewable facilities. Iberdrola promotes the decarbonisation of the economy through greater electrification, especially in sectors such as transport (through electric vehicles) and buildings (through heat pumps).

The objective of both the Paris Agreement and the commitments being made by Europe is that of an emission-free society by 2050. By then, the energy carriers will have to be fully decarbonised, meaning there will no place for the fossil fuels being used today.

Digital, intelligent and innovative solutions to give the customer more decision-making power

The José María de Oriol power plant, with more than 50 years of history, is a hydroelectric facility located in the municipality of Alcántara, in Cáceres. With a total installed capacity of over 900 MW, the plant is one of the cornerstones of Iberdrola's renewable energy production in Extremadura, in southwest Spain.
