Hydroelectric Plants in West Africa - other countries
Operator: Volta River Authority
Configuration: 5 X 165 MW Francis
T/G supplier: Hitachi, Canadian General Electric
EPC: Kaiser Engineers & Constructors
Quick facts: This is the fourth largest conventional hydro plant in Africa. The 134m rock-fill dam has a crest-length of 671m and impounds Lake Volta, one of the world's largest reservoirs. Development started in 1949 when the Gold Coast government commissioned Sir William Halcrow & Partners to examine development of the Volta River basin. Work got underway in 1959. An extensive modernization effort is ongoing for the electro-mechanical equipment.

Operator: Bui Power Authority
Configuration: 3 X 133 MW Francis
T/G supplier: Tianjin Alstom Hydro
EPC: Sinohydro, Coyne et Bellier
Quick facts: The Bui Gorge on the Black Volta River was first identified as a potential hydropower site in the 1920s and since 1956, five technical site investigations were undertaken, including one in 1995 by Coyne et Bellier. The dam is 150km upstream of Lake Volta where the Black Volta constitutes the border between the districts of Bole (Northern Region) and Wenchi (Brong-Ahafo Region). The 40km reservoir is entirely within Ghana. Three new 161kV transmission lines run eastward to the existing Techiman-Wa line, and then south to substations at Kumasi and Techiman. Bui was a complex project, made more difficult by the need for simultaneous development and implementation of a management plan for the Bui Natl Park, which includes most of the reservoir area. In July 2001, Environmental Protection Agency of Ghana published the final Bui EIA. In Nov 2005, the government signed an MOU with SinoHydro for the EPC work. Construction on the main 90m RCC dam began in Dec 2009 and the first unit came online in May 2013. The plant cost about $622mn.

Location: Equatorial Guinea
Operator: Sociedad de Electricidad de Guinea Ecuatorial
Configuration: 4 X 30 MW Francis
T/G supplier: Chongqing
Quick facts: Project construction began in Mar 2008 and the plant was inagurated in Oct 2012. A 220kV substation was built in conjunction with the power station. The EG government funded the Djibloho scheme with assiatance from the Chinese government.

Operator: OMVS - Organisation de la Mise en Valeur du Fleuve Senegal
Configuration: 3 X 21-MW bulb
T/G supplier: Harbin
EPC: Sinohydro No 14
Quick facts: In Jul 2006, the World Bank approved three $25mn IDA credits to implement the Felou hydropower project near Kayes. OMVS and SOGEM were the project leads and the grants were made to Mali, Mauritania and Senegal. The Felou HPP is part of an integrated regional development plan under the auspices of the West African Power Pool (WAPP). The site is about 15km from the existing transmission line from Manantali-Bamako transmission line and is connected to a new 225kV line running to Kaoleck in Senegal. The $115mn project is jointly-funded with the European Investment Bank (EIB). Felou was inaugurated in Dec 2013 and should supply about 325 GWh/yr to the regional grid.

Operator: Societe d'Energie et d'Eau du Gabon (SEEG)
Configuration: 4 X 40 MW Francis
T/G supplier: Toshiba Hydro Power (Hangzhou)
Quick facts: In Nov 2008, the foundation stone was laid for the Grand Poubara HPP upstream of the Poubara waterfalls on the Ogooue River, 15km from Franceville. The project has a 37m tall RCC dam. The river diversion was completed in Nov 2010 and the plant commissioned on 5 Aug 2013, about 3mos past schedule. China Exim Bank supplied most of the financing for the CFA 280bn project. Gauff GmbH & Co Engineering KG served as an engineering and construction management advisor. Two transmission lines were built, a 62km, 225kV line to the Moanda ferromanganese plant and a 21km, 115kV line to Franceville, the two main urban areas in the province of Upper Ogooue.

Operator: Societe de Gestion de l'Energie de Manantali (OMVS)
Configuration: 5 X 40 MW Kaplan
T/G supplier: Sulzer
EPC: Tractebel, Tecsult, Fichtner
Quick facts: This power station is on a concrete irrigation dam completed in 1992 on the Senegal River. The dam has a 1,500m crest and a maximum height of 66m. The tender for the powerhouse was issued in Sep 1993 and the turbines were ordered in 1996. The scheme includes two 225kV transmission lines, one to Bamako and one to Dakar plus a 132kV transmission line to Nouakchott, substations and a dispatching center. Funding was from the World Bank the African Development Bank, the Islamic Development Bank, the European Investment Bank, the Arab Fund for Economic and Social Development, and assorted donors in Europe, Canada, and the U.S. At the time of the initial loans, the total cost for the completion of the HPP and transmission system was estimated at $444mn. Later reports put the cost at more like $500mn. In July 2001, Eskom Enterprises signed a 15yr operation for Manantali. Mali receives 52% of the energy generated, Senegal 33%, and Mauritania 15%. The first turbine was put online in late 2001.
