Studi Inventarisasi Emisi Gas Rumah Kaca (CO2, N2O, dan CH4) dari Aktivitas Pembangkit Listrik Tenaga Gas dan Uap (PLTGU) PT. PLN UPDK Belawan

Abstract

PT PLN Belawan Gas and Steam Power Plant (PLTGU) is the main supplier of electricity needs in the North Sumatra System. In its operational activities, this PLTGU produces greenhouse gas emissions (CO2, N2O and CH4), both from stationary sources (chimneys) and mobile sources (transportation). This PLTGU uses diesel oil as fuel but in 2015, this PLTGU replaced natural gas as a permanent fuel. The purpose of this study is to determine the amount of annual emission load generated from stationary sources and mobile sources at PT PLN UPDK Belawan and to determine whether there is a difference in the emission load generated when switching the type of fuel from diesel oil to natural gas in the operation of the PLTGU. The method of calculating the emission load for stationary sources used is the Intergovernmental Panel on Climate Change (IPCC) Tier 1 method. While the method of calculating the emission load for mobile sources used is based on the Regulation of the Minister of Environment Number 12 of 2010 concerning the Implementation of Air Pollution Control in the Region. Based on the results of the study, it is known that the annual emission load from stationary sources of PT PLN UPDK Belawan, 6,205,806.67 tons of CO2 eq/year and mobile sources is 9.06 tons of CO2 eq/year. There is a difference in the emission load generated when switching the type of fuel from diesel oil to natural gas in the operation of the PLTGU, which is 20.85%. The selected scenario for reducing emissions for immobile sources is fuel substitution, natural gas fuel is chosen to be a permanent fuel in the operation of the PLTGU. While the emission reduction scenario for mobile sources is replacing employee buses with electric buses with a larger capacity.
