Quick facts: Development started in 1957 for this $1.7bn multiuse project on the Guadiana River in south central Portugal. The 96m dam created Europe’s biggest man-made reservoir measuring about 80km long. In Sep 1995, EDP signed a protocol agreement with state-owned Empresa de Desenvolvimento e Infraestruturas do Alqueva SA (EDIA) to complete the development. In 2001, the EIB made a €65mn loan for the plant and the dam floodgates were closed in Feb 2002 despite continuing protests from environmentalists concerned that the new reservoir would have detrimental effects on the regional environment. The scheme includes the construction of nine small dams and about 5,000km of canals and pipelines to irrigate 110,000ha. The Pedrogao Dam was built 23km downstream to create a regulating reservoir. In 2008, EDP signed a contract worth about €95mn to add two more units to supply additional storage capacity for new wind plant. On 23 Jan 2013, the second phase was inaugurated with two more 130-MW PSP sets.
