In Jun 1989, the Guinean government gave the consortium the responsibility for detailed design and the drafting of tender documents. Most of this contract was financed by the Caisse Centrale de Cooperation Economique Francaise. Ultimately a rockfill dam with a storage capacity of 1.6bn m³ and a powerhouse were built at a cost of about $200mn. Garafiri suffered a variety of mechanical problems, including a serious breakdown in 2002, but the generating equipment has subsequently been refurbished.
