Hybrid of photovoltaic and diesel power plant in Celagen Island

Abstract

Celagen Island is one of the outer islands in Bangka Belitung Islands Province. The population of Celagen island is 1234 people and dominated by fishermen. Currently, electricity is supplied from 1 unit of photovoltaic with capacity 80-kWp and coupled with three units of diesel power plant with capacity 100 kW. To meet the electricity needs of 1069 kWh/day, supply from diesel power plant already sufficient. But for the economics of the cost of providing primary fuel, a hybrid from photovoltaic and diesel power plants needs to be done. Hybrid power plants are one of the options to meet the electrical energy needs of geographically difficult areas to connect to the on-grid electricity network. The hybrid system with 72% of electricity from the diesel power plant and 28% of electricity from photovoltaic is very economical. The economic analysis shows that with this modeling, the cost of providing primary fuel is lower by 1228 rupiah/kWh if only using diesel power plant.
