Techno-economic analysis of west Kalimantan electricity system with 100MW nuclear power plant as baseload: Projection of 2030.

West Kalimantan is one of provinces in Indonesia with population approximately 5.47 million people. Currently, most of the electricity demand is supplied by fossil energy and still importing the electricity from Malaysia. The large use of fossil energy causes a negative impact to the environment as they contribute to the spread of CO2 emission and other harmful pollutants into the environment. In order to decrease this emission, utilization of nuclear power plant will be a rational choice with its several advantages. In this study, West Kalimantan electricity system was modelled as an isolated system without grid interconnection to other regions and the system will consist of coal, gas, hydro, bio, solar, energy storage and 100MW nuclear power plant (NPP) as base load. Hybrid Optimization Model for Electric Renewable (HOMER) software was used to determine the techno-economic parameters of the electricity system under multi-scenario. The result shows NPP could help the government to meet the new and renewable energy (NRE) and emission reduction target effectively. Nuclear scenarios show that on 2030 there will be at least 6¢/kWh additional cost to generate electricity and more than 1.4 Billion USD as initial cost. In conclusion, government should give several attractive investment option especially on nuclear power plants as the highest capital cost technology to achieve the new and renewable energy (NRE) and emission targets.
