The complex project was made to produce hydroelectric power, irrigation for farms in the surrounding area, as well as a large reservoir where several tourist ventures are also being built. Hydroelectricity is electricity generated by Hydropower, ie the production of power through use of the gravitational force of falling water Irrigation is an artificial application of water to the soil usually for assisting in growing crops Tourism is Travel for Recreational or Leisure purposes The World Tourism Organization defines tourists as people who "travel Alqueva, a village of about 350 inhabitants, gives the project the name. It is the site of the biggest ostrich farm in Portugal.
The Alentejo is the driest and hottest region in Portugal. Persistent droughts are a problem. The climate and a lack of infrastructure has impeded economic development and isolated the area from the national and European economies. The European Union ( EU) is a political and economic union of twenty-seven member states, located primarily in
During the 1950s, the Portuguese dictator, António de Oliveira Salazar, ordered a study of the feasibility of the dam project. António de Oliveira Salazar, GColIH, GCTE, GCSE, pron. ɐ̃'tɔniu dɨ oli'vɐiɾɐ sɐlɐ'zaɾ The potential benefits of the Alqueva dam were discussed for decades. An initial effort was undertaken after the Carnation Revolution of 1974, but it was abandoned in 1978. The Carnation Revolution (Revolução dos Cravos was an almost bloodless military-led pro-democratic Coup d'état, started on April 25, 1974, in Lisbon The Portuguese government eventually made a firm decision to build the dam in the 1990s, during the Cavaco Silva and António Guterres governments.

In 2004, the hydroelectric power station started to work, with a capacity of 240 megawatt. As of 2025 (though the endeavour is already slated to be finished by 2013), the lake should supply irrigation water for 1,100 km² in the Alentejo.
