ENHER, the acronym for Empresa Nacional Hidroeléctrica del Ribagorzana (National Hydroelectric Company of the Ribagorçana), was a Spanish company, based in Barcelona, dedicated to the generation and distribution of electrical energy. Its basic activity focused on hydroelectric production, but also had holdings in thermal and nuclear power stations.
Created in 1946, it was historically a company of public capital, first as property of Instituto Nacional de Industria (INI) and, from 1983, as part of Endesa, who absorbed it in 1999, one year after being privatized. Despite the extinction of the legal personality of Enher, Endesa used the Fecsa-Enher trademark for its distribution activity in Catalonia until the year 2001.[1]
