Hydroelectricity
There is a gravity dam with a head and hydroelectric power plant on the river less than from the city center, built in the 1950s.
In March 2013 Andritz Hydro Switzerland was awarded a contract to rehabilitate and upgrade HPP Djoué.
The power plant had been out of operation since April 2007, when the control room was flooded, and the tailrace channel had been completely silted up by the biannual floods of the Congo River.
