Project Overview

The Mount Coffee Hydropower Plant is a hydroelectric facility built in the 1960s.  During the Civil war in the 1990s the rebels seized the area around the dam, preventing the slice gates of the dam spillway from being opened at a critical time, causing a breach to a section of the Dam resulting in failure.  Since that time, the power plant has been pillaged, leaving only the bare structure. 

The Rehabilitation of Mount Coffee Hydropower Plant project will transform the existing site to a working hydroelectric scheme that will provide cost effective electricity to Monrovia and the surrounding areas.  

Dawnus International secured the Enabling Works phase of the project in December 2013 with an initial 13 week construction period.  Subsequent additional works were awarded that extended the programme duration to September 2014. A summary of the activities are as follows: 

  • Establishing an advanced camp to facilitate the enabling works activities and provide accommodation for future phases of the scheme.
  • Ground investigation works and production of ground investigation reports.
  • Cleaning the powerhouse.                                                    
  • Design and construction of three earth engineered cofferdams up to 150m wide x 12m high.
  • Dewatering between cofferdams, enabling access to the powerhouse for inspection.
  • Construction of 1.2 km of gravel road.
  • Site clearance (by hand) of 90 Ha of bush and trees.
  • Casting and installation of approximately 600 reinforced concrete marker posts around the perimeter of the upstream reservoir, which will be created when the main dam is reinstated.
