With the continous increase of human population, the demand for electricity would increase accordingly. Therefore, various efforts of electrical generation are needed to satisfy those increasing demand. The construction of Micro Hydropower Plant (MHP) at Sabuga Weir, Bandung City, West Java that utilise existing weir, intake, and waterway may present as an economical and environment-friendly alternative in regard of increasing electrical supply for the public need. Based on the optimation calculation of electrical energy production, discharge with exceedance probability of 60% (3.33 m3/s) is determined to be utilized as the design discharge. Sabuga MHP produces 424.8 kW of electrical power with 17.12 m of gross head. The turbine used is kaplan turbine, with the runner sizing to 0.66 m in diameter, and a rotational speed of 1000 rpm. Investment capital of Rp. 52.16 billion is needed in purpose of constructing the Sabuga MHP with an annual benefit of Rp. 1.89 billion per year, which produces annual BCR of 0.036, payback period of 27 years 8 months, internal rate of return of 16%, and cost per kW of Rp. 122,792,611.
