Abstract

The total catchment area of Cameron Highlands
Scheme is divided into two parts: the upper catchments
and the lower catchments. Among the greatest challenge
to continue running hydropower as a source of clean
energy is to continuously prevent loss of reservoir storage
volume due to sedimentation. The total storage capacity of
Ringlet Reservoir, Cameron Highlands was designed at
6.7 million m3 with an estimated life span of 80 years.
However in just 35 years of operation since construction,
almost 52% of its storage was already taken up by
sediments which left the reservoir with a balance lifespan
of 4 years if no mitigation measures were undertaken. It is
also estimated that the trapping efficiency at the reservoir
would have been significantly reduced by almost 37%
since construction in the absence of any sediment
mitigation measures. The paper discusses the challenge
and impacts of sedimentation to hydropower generation,
estimation on present reservoir trapping efficiency,
estimated reservoir life expectancy as well as the
mitigation measures undertaken to continue running
hydropower as a source of “clean energy”.
