LESSP, direct communication 2012-04-23 From these few examples, it becomes quite evident that project of this type can be solutions especially for remote areas, for which it is unlikely that they will be connected to a main grid in the short or medium term. However, they cannot really be considered as an alternative to Mt. Coffee or other medium to large sized hydropower projects). 24.3 Conclusions The main conclusion from this evaluation is that the rehabilitation of Mt. Coffee, as currently planned, is the preferred option from an environmental and social point of view. The benefits from this Project by far outweigh its negative impacts, and the evaluated alternatives are less advantageous.
WEST AFRICAN POWER POOL (WAPP) PÖYRY ENERGY LTD. Mount Coffee HPP ESIA and RAP 2012-09-18 ESIA Report Page 179 25 ECONOMIC EVALUATION 25.1 Objective and Approach 25.1.1 Objective and Scope 25.1.2 Data Base The project to be considered under the present assignment (the Project) is the rehabilitation of the Mount Coffee Hydropower Plant (MCHPP). This project can shortly be described as follows: � located on the St. Paul River, approximately 27 km northeast of Monrovia, in Montserrado County; � dam with gated spillways, forebay dams, forebay canal, intake structure, penstocks, powerhouse designed to accommodate 6 vertical Francis units, tailrace canal, substation and transmission line; � two units (installed 1966) of 15 MW each, and two units (installed 1972) of 17 MW each, total installed capacity 64 MW. � designed as Run-of River (ROR) scheme; � small reservoir with limited storage and regulating capacity; � lowermost dam in a planned cascade of a total of 5 dams, the others going to be storage dams with large reservoirs. Within the frame of the preparation of an Environmental and Social Impact Assessment (ESIA) and the preparation of a Resettlement Action Plan (RAP), the Terms of Reference of the Contract requires that an economic assessment of the rehabilitation project has to be carried out. This assessment shall consider the following points: � the project alternatives under discussion � the present energy supply situation of the country � the energy requirement forecasts, as far as available � aspects of economy (including, but not limited to energy costs � estimated construction duration � environmental and social effects � the no-project case (i.e. the present situation without rehabilitation of the power plant). 25.1.2.1 Preliminary Remarks Numerous studies concerning the power situation in Liberia and the Mount Coffee Hydropower Plant have been carried out in the last years. For the present evaluation of the MC HPP data have been collected in Liberia and from the internet.
