Gabon connects Kinguélé Aval dam to Libreville grid
Eight days of work to connect the 35 MW Kinguélé Aval hydroelectric plant to the Libreville power network.
The Société d’énergie et d’eau du Gabon (SEEG) began final connections for the Kinguélé Aval hydroelectric plant to Libreville’s 225 kV power line on November 6. The work, conducted by Sinohydro until November 13, aims to integrate 35 MW of new electricity into the capital region’s supply.
This connection process requires temporary reductions in power output from other plants, leading to rotating power outages in Grand-Libreville for eight days. SEEG estimates a deficit of 40 to 50 MW during peak evening hours, imposing approximately three-hour blackouts.
Once operational, Kinguélé Aval will provide an additional 35 MW, representing about 13% of Grand-Libreville’s energy needs. The plant, built on the Mbei river, is Gabon’s first public-private hydroelectric partnership and is expected to produce around 200 GWh of renewable electricity annually.
Why it mattersResidents and businesses in Grand-Libreville will experience rotating power outages for eight days while the Kinguélé Aval hydroelectric plant is connected to the main power grid.
