El Chorro Station was supposed to be just a beginning of a long and successful existence of the Hydroelectric Company El Chorro. All along the 20th century, the company’s policies were expansion and consolidation of activities related to electric power production and supply. Just before the Civil War, the company focused on improving its production facilities, transport, energy supply and fraud detection. They also made contracts with other important electricity production companies, such as Sevillana de Electricidad or Mengemor.
During the Civil War, El Chorro expended the area in which it sold electric power because other companies, affected by the war, produced less. After the war, the company continued with its expansion in and out of the province. This way, at the end of the 1940s, the power station produced and supplied the City and the province of Málaga and Almería, and some of the important villages in Granada, Córdoba and Seville with electric power. Ten years later, El Chorro acquired the Electric Power Company Segura, and managed to start supplying a lot of villages in Murcia.
