Immediately after its creation, the company installed its first power plant in the premises of a former yarn and textile factory in Barcelona. This gave way to the era of industrial electrification in Spain. It was therefore a pioneer, firstly, in the production of electrical equipment and, secondly, as a commercial electricity product.
Years later, in mid-1883, SEE installed its most important generation plant "Les Hortes de San Bertrán", which ended up becoming the company's main facility.
"At the time it was not easy to build an industry like that of electricity production. Demand was needed, in addition to a distribution network, and a plant was required to be built that, at the time, was really expensive to build and maintain due to the coal consumption", explains Luis Urteaga, professor at the University of Barcelona. "Sociedad Española de Electricidad, like all pioneers, had some difficulties, such as technological uncertainty or doubt as to which technical solution was most appropriate at the time."
