Abstract— Microhydro is one among various renewable
technologies that can be developed to generate clean and
sustainable electricity in Bali. As a result, the local utility
company has planned to develop several mini-hydro in Bali for
the next five years with total capacity of 30 megawatt. Two micro
hydro plants each of 25 kW and 20 kW capacity are currently in
operation to generate electricity for villagers as well as injecting
power into local grid. Many villages in Bali pose great potential
to generate electricity using micro hydro from streams or rivers
nearby the village which forms their irrigation systems. The
report presented on this paper is result of study to develop micro
hydro in the village of Sambangan in District of Buleleng. The
power plant is intended to improve existing generic plant to
provide more reliable and better quality electrical power for
villagers which has no access to utility grid. The village has
irrigation canal with historical water flow of 623 liter per second
minimum and with an effective head of around 18 meter.
Summary of technical specification of the proposed 82 kW micro
hydro is presented. The total cost for developing this plant is
estimated at around 1.5 billion Rupiah that includes civil,
mechanical and electrical, as well as distribution network cost
components. The cost of each work component is estimated based
on empirical data on previously built or design micro hydro
around Indonesia. An organization that empower local
manpower is also identified to operate and maintain the power
plant effectively and sustainably.
