The Cahora Bassa - or Cabora Bassa - dam is the largest dam built by Portugal. It is located on the Zambezi River, in the district of Tete, in Mozambique, meaning, in the language of the country, "where work ends", water which prevented the inhabitants from passing the river beyond that point.
Construction began in 1969 and was completed in 1974. With a height of 164 metres and an arch of 303 metres, it has a capacity of 63,000 million m3 of water and can produce 2075 gigawatts per hour.
The main consumer of the energy produced by this dam is South Africa. Some sources point out that during its construction during the Colonial War, the dam was the target of several attacks and boycotts by the Mozambican resistance, as they considered that Portugal wanted to gain the support of South Africa in its colonial struggle.
One of the priorities is to supply energy at low cost (one of the lowest in the world) to South Africa, due to the agreement made between Portugal and South Africa in 1969.
