The Nangbeto Dam dams the Mono , the largest river in the West African state of Togo , about 160 kilometers north of its confluence with the Atlantic Ocean . The reservoir is located near Atakpamé near the border with Benin .
The dam is a partner project for electricity generation between Togo and neighboring Benin and was completed in 1987. The construction was carried out mainly by the German construction company Hochtief AG , the financing of the 110 million DM project was largely carried out by loans from, among others, the Kreditanstalt für Wiederaufbau , the World Bank , the African Development Fund and also from development aid.
The dam consists of a 443 m long main dam made of rubble material, which is 157 m wide at the base and reaches a height of 52 m. Its building volume is 1.1 million cubic meters. The dam's side dams reach a total length of over 5000 m. The reservoir has a storage capacity of 1.71 million cubic meters.
The dam was built for irrigation and to generate electricity from hydropower . Two Kaplan- type turbines each have a capacity of 32.5 MW. The hydropower plant delivers between 230 million kWh and (1991) 150 million kWh annually. Because the water level is too low, it is not possible to generate electricity for several months. The operator is Communauté Electrique du Bénin (CEB), a state company in which the states of Togo and Benin are involved.
Between 7,600 and 10,000 people had to leave their villages for the dam. There should not have been a resettlement plan. Its construction also had a significant impact on the ecology of the lagoon system at the mouth of the Monos, as the seasonal fluctuations in the amount of water have been reduced by the dam.
