25.2.2 Study Options for the Development of Liberia’s Energy Sector
The paper “Options for the Development of Liberia’s Energy Sector” was completed in
October 2011 for the International Bank for Reconstruction and Development. Its
purpose was to show options for the supply of electricity to Liberia. Accordingly a
Least-Cost Energy System Expansion for the Period 2010 to 2040 was developed.
For the preparation of this system expansion plan, about a dozen options were studied.
The rehabilitated Mount Coffee Hydropower Plant and a few other hydropower projects
to be located on the St. Paul River formed some of the considered options.
The technical and economical characteristics of the considered hydropower plant
options were taken over from the Stanley Consultants Feasibility Study of 2008 and are:
Table 25-3: Considered HPP options, technical and economic characteristics
Project Name Capacity Energy Capital Cost
MW GWh Million US $
Mount Coffee 66 342 162
Mount Coffee + Via storage 66 435 383
SP-1B +SP-2 + Via storage 198 1’960 879
St Paul-2 (SP-2) project is located on the St Paul River 60 km downstream of the
planned Via Reservoir. It will produce 1’330 GWh. St Paul-1B (SP-1B) will be located
40 km downstream of SP-2 and will produce 630 GWh.
The capital costs shown in the preceding table are expressed in 2008 US $. For the
development of the least cost expansion plan, these costs were updated to the year 2009
and discounted to the year 2010 with a discount rate of 12%.
