Abstract: In Liberia, as in many developing countries, electrification of towns and cities throughout the country has long been a major development goal. However, fuel expenditures by the Liberian Electricity Corporation (LEC) for its rural public stations represent a major and growing burden on the financially hard‐pressed utility. In this paper we evaluate the economics of supplying wood to rural electric power plants utilizing different sources of feedstock. We also evaluate the cost implications of differences in wood supply requirements based on the use of steam or gasifier technology, and from variation in plant utilization level. The wood supply we consider as sources are: (1) retired rubber trees; (2) the harvesting of secondary‐growth forest just before the land is returned to temporary cultivation; (3) the establishment of commercial short‐rotation wood energy plantations; and (4) adding to the system of shifting agriculture the planting of fast‐growing wood species. The results indicate that wood can probably be supplied under a wide range of supply and demand conditions for US$1.00–1.70 per GJ. We estimate that wood steam plants can generate power for about $0.09‐0.14 per kWh and gasifier plants for $0.10‐0.18 per kWh. These costs are well below the present cost of oil‐based rural electric power generation in Liberia (about $0.20–0.27 per kWh).
