|Abstract: ||At present, there prevails a major incongruity in the mode
of energy supply in Ethiopia. According to the status of 1992
electrical energy demand and supply balance, not more than half
of the generated energy is taken-up by the existing urban
consumption and industrial centers. The electrical energy
excess arose from the industrial underdevelopment which has
been characterstic of Ethiopia in recent years.
But, the stated energy imbalance does not represent the rural
areas where more than 80% of the Ethiopian population live and
where in most cases no electrical energy is supplied. The
thesis adresses the problem from the stated contradiction and
recommends the decentralization of energy supply in general and
the dessimination of micro-hydropower in particular.
The numerous technical, socio-economical, and environmental
advantages offered by decentral systems to developing countries
make small schemes preferable to central supply systems inspite
of the apparent effect of economies of scale which generally
favour the latter.
Improvement of the economics of decentral energy supply by
integration to mUlti-objective schemes is suggested. The thesis
looks into possibilities of fitting decentral hydropower to an
already completed multi-purpose small-scale water resources
study, in one region in Ethiopia, which seems to have
overlooked this important objective.
Ethiopia, commonly known as 'The Water Tower of East Africa'
is relatively richly endowed with hydropower resources than
neighboring countries in the region. However, local hydropower
resources for isolated energy production are only slightly
investigated with a very minimum level of utilization. The
thesis compiles recent implementation efforts and
reconnaissance level studies of decentral hydropower in
Ethiopia. A full investigation of available local hydropower
resources requires further research for which the thesis
recommends appropriate study techniques with application to a
few gauging stations in the country.
Economic analysis of a micro-hydropower station with a
conservative approach under Ethiopian conditions shows a fair
degree of viability with reasonable amortization. Practical
micro-hydro power implementations in the country indicate a
rational level of profitability through the use of local labour
