Abstract

Bali Province is one of the areas that has abundant renewable energy potential. Through increasing the role of renewable energy in the national energy mix which is a government program, which aims to reduce the use of non-renewable energy and open community participation in utilizing renewable energy in Bali Province. To overcome these problems, an analysis of the investment costs of developing renewable energy plants in Bali Province in 3 scenario modeling was carried out. In this scenario modeling is carried out to determine the investment cost of developing renewable energy plants in Bali Province in the 2024 - 2045 time span. The results of this study show that renewable energy investment costs in the optimistic scenario require investment costs of 264,12 Million USD in 2024 increasing to 2.078,35 Million USD in 2045 with total investment costs during the modeling period of 46.477,10 Million USD. The moderate scenario requires investment costs of 264,12 Million USD in 2024 increasing to 1.186,30 Million USD in 2045 with total investment costs during the modeling period of 27.362,52 Million USD. The pessimistic scenario requires investment costs of 264,12 Million USD in 2024 increasing to 986,80 Million USD in 2045 with total investment costs for the modeling period of 20.817,04 Million USD.

Abstract

The Bali Provincial Government has declared a commitment to achieve Net Zero Emissions (NZE) by 2045. This involves transitioning from non-renewable energy sources to renewable energy to reduce emissions from the energy sector. The policy aligns with the growing demand for electricity and the abundant renewable energy potential in Bali Island. Three scenarios were simulated using the Open Source energy Modelling System (OSeMOSYS) software to evaluate Bali power system with renewable energy potential from 2024 to 2045. The results indicated that to achieve NZE in year 2045, for the optimistic scenario, the renewable energy share may reach 85.62% and result in a reduced emission to 5.78 million tons of CO2eq. For the moderate scenario, Bali Island is required to have a renewable energy share of about 84.13% and 4.15 million tons of CO2eq at the end of year 2045. Meanwhile, for the pessimistic scenario, the renewable energy share must be about 82.65% and with an emission of 3.19 million tons of CO2eq in 2045.
