Description
One of the reservoir management options for flood moderation and energy production is the operation of
Hydropower Dams to protect people and their socio-economic activities in flood plain areas. This study focuses on
assessing Jebba Hydropower Dam Operation for improved energy production and flood management. Available Data for
27-year period (1984 - 2011) such as inflow, elevation, turbine release, generating head, energy generation, tailrace water
level and plant coefficient was obtained from Jebba Dam Station. The present reservoir-operating rule was investigated
using statistical analysis to model the operation of the multi-purpose reservoir. Statistical tests carried out in accordance
with standard procedure include chi-square (χ2), probability plot coefficient of correlation (r), and coefficient of
determination (R2). The results show that the optimal solution at operating performance of 50% reservoir inflow reliability
has the total annual energy generation of 42105.63MWH with adequate water supply for downstream users and for
irrigation throughout the year with annual optimal evaporation losses averaged at 58.16Mm3. Average optimal energy
generation obtained is 19% of the observed energy generation but with adequate water supply for downstream users and
for irrigation throughout the year. It is, therefore, essential to develop a decision-making framework capable of handling
the conflicting demands
