Contribution of Solar Photovoltaic on the Reduction of Greenhouse Gas Emission in the Indonesia Power Sector

Abstract

Indonesia has released the target of reducing Greenhouse gas (GHG) emissions. The strategy includes enhancement renewable energy utilization. One of the most potential renewable energy resources in Indonesia is solar energy. State Electricity Company of Indonesia has planned to develop solar Photo voltaic (PV) power plan in the document planning 2019-2028. The objective of this study is to explore the contribution of solar PV to the reduction GHG of Indonesia. The potency of solar irradiance and solar PV output in several big cities in Indonesia are discussed. The results show that by using the PV technology of Crystalline silicon with mounting position building integrated and the slope and azimuth is 0°, the average solar PV output in Indonesia is 1361.2 kWh/kWp. The planned solar PV installed capacity by the end of 2028 is 985.5 MW. The electricity resulted by the system in a year will be 1341.47 GWh or it is only 0.31% of national electricity consumption. The contribution of solar PV to the GHG emission reduction is 1.341 million tons CO2eq in the year 2028.
