Abstrak/Abstract |
Indonesia is an archipelagic country consisting of many islands, such as Halmahera Island. Halmahera
Island is one of the crucial islands due to its enormous nickel mining potential. Therefore, this island has high growth
of nickel mining and processing industries. However, the low electrification ratio of 89,33% will become an issue in
the future, as the electricity demand will continue to increase on a large scale in the future. Therefore, a generation
expansion planning (GEP) study is performed in the Halmahera electricity system for the 2026-2050 period. The
Mixed Integer Linear Programming (MILP) method is used to determine the power plant development variables. The
result shows that biomass is selected as the local energy resource for power plant development alongside coal and gas
machine power plants. Therefore, to achieve the renewable energy mix target, energy supply from biomass, coal and
gas machine needs to be 66.11%, 4.11% and 30.04%, respectively. Furthermore, this power plant combination
achieved the target of renewable energy mix without violating the reliability with the approximately same electricity
generation cost, IDR 1,495/kWh. |
