Featured Project

Dugbe Hydroelectric Project

The Dugbe Hydroelectric Project is a proposed 15 to 30 MW run-of-river project in the southwest region of Liberia. The project will provide power to the proposed Dugbe mine and supply additional power to the nearby town of Greenville. The project will include up to three run-of-river intake structures diverting flow to a common forebay, a buried penstock(s), and a surface powerhouse with Francis turbines. The project will have approximately 40 m of head, a design flow of 45 to 90 m3/s, and an installed capacity of 15 to 30 MW.
