Planning for the utilization of hydro power in the Belayan river, East Kalimantan

Abstract

Non-renewable energy power plants are barely able to meet all electricity needs but they have negative impacts on the environment as does greenhouse gas pollution. For now, investors and academics are competing to make renewable energy power plants, one of them is hydroelectric power plant. National Energy General Plan Data (RUEN) issued by the government shows that East, Central and South Kalimantan has water potential in the amount of 16.844 MW. Therefore, this study chose Tabang, East Kalimantan as a case study to build a hydroelectric power plant. Belayan River according to the East Kalimantan Region III River Agency has potential water reaches 424,36 m3/s, so it is very strategic for hydroelectric power plants. The survey results provide 3 possible alternatives for dam construction. The type of water turbine chosen is Francis vertical shaft with output power 71.701,98 kW and generator with output power 69.550,922 kW. The output power that can be generated by this hydroelectric power plant is equal to 280 MW by use 4 generating units.
