ToursExplore Lably’s 3D toursWith partial funding from the Exim Bank of China, the engineering, procurement and construction (EPC) contract was awarded to Sinohydro, the Chinese hydropower engineering and construction company. CI-Energies is the expected off-taker of the energy generated here. Construction is reported to have started in 2021, with commissioning anticipated in 2024.
Location
The power station lies across the Sassandra River, about 15 kilometres (9 mi) downstream of Soubré Hydroelectric Power Station, outside the city of Soubré. Soubré is located in the Soubré Department of the Nawa Region in the Bas-Sassandra District, in southwestern Ivory Coast. This is approximately 366 kilometres (227 mi), by road, northwest of Abidjan, the financial capital and largest city in the country.

Overview
This power station is one of three hydroelectric power stations on the Sassandra River, downstream of the Soubré Hydroelectric Power Station. These three dams, when completed, are expected to add a total of 508 MW to the national generation capacity, according to the Ivorian authorities. The dams are Gribo-Popoli HPP: 112 megawatts, Boutoubré HPP: 150 megawatts and Louga HPP: 246 megawatts.
The work at this site includes: (a) building an earth filled dam measuring 4,000 metres (13,000 ft) in length (b) six spillway gates (c) an above-ground powerhouse with a total installed capacity of 112 MW (d) a 225kiloVolt switchyard (e) two 8 kilometres (5 mi) overhead (single circuit) high voltage evacuation transmission lines connecting this power station to the 225kV Soubré–San Pedro high voltage power line (f) 23 kilometres (14 mi) of permanent access roads.
Construction costs and funding
The estimated cost for the dam and power plant is reported as US$308 million. The Exim Bank of China has lent US$287 million, with the balance contributed by the Ivorian government as equity investment. The table below lays out this information in tabular form.
Other considerations
This power station will increase the national generation capacity by 112 MW of clean energy and will help to propel the county towards 6 Gigawatts of installed capacity by 2030, that the Ivorian government is aiming at.
