Abstract

Degradasi lingkungan akibat peningkatan emisi gas rumah kaca (GRK) dari sektor ketenagalistrikan merupakan tantangan besar bagi Indonesia, terutama dengan pertumbuhan kebutuhan listrik yang berkelanjutan. Pemilihan upaya dekarbonisasi pada pembangkit listrik yang efisien biaya menjadi krusial. Penelitian ini menganalisis upaya dekarbonisasi terhadap pengembangan di sistem kelistrikan Sulawesi Bagian Selatan, mengevaluasi dampak penurunan Emisi Karbon dan Implikasi Ekonomi- Biaya Pokok Penyediaan Tenaga Listrik (BPP). Penelitian ini menganalisa 2 skenario utama dibandingkan dengan operasi Business as Usual (BaU) seperti yang tercantum pada RUPTL (2021-2030): (i) Substitusi Bahan Bakar/Co-Firing dan EBT (Moderat) dan (ii) Implementasi Co-Firing, EBT dan Carbon Capture & Storage (CCS) pada Pembangkit Fosil (Ekstrem). Analisis dilakukan pada periode 2022-2030, dengan penambahan pembangkit yang konsisten berdasarkan RUPTL 2021-2030. Hasil menunjukkan bahwa pada tahun 2030, skenario Moderat dan Ekstrem dapat menurunkan emisi masing- masing sebesar 28,4% & 56,7% dari BaU; 1,410 kg.CO2/kWh. Namun, upaya dekarbonisasi ini memerlukan investasi tambahan yang signifikan, berkisar antara 403,57-3.855,64 Juta USD, yang menyebabkan peningkatan BPP sebesar 1,38%- 29,12% dari Operasi BaU; 13,27 ₵.USD/kWh, terutama karena kenaikan harga bahan bakar. Terjadi Pinalty Cost sebesar 9,8 USD dan 103,9 USD untuk menurunkan Emisi sebanyak 1 MT.CO2. Implementasi CCSU pada PLTU dan PLTGU memungkinkan penurunan Emisi CO2 hingga 86%, tetapi dapat meningkatkan BPP hingga 65% dari BAU. Temuan ini penting sebagai pertimbangan untuk mencapai target penurunan emisi GRK Nasional Indonesia.

Environmental degradation due to increasing greenhouse gas (GHG) emissions from the electricity sector poses a significant challenge for Indonesia, particularly with the continuous growth in electricity demand. Therefore, selecting the Decarbonization efforts for power plants with cost-efficient production is crucial. This research analyzes decarbonization efforts of Development within the South Sulawesi Grid System, evaluating the impact of carbon emission reduction and the economic implications on the Cost of Electricity Generation (COE). This study examines two main scenarios compared to the Business as Usual (BaU) operation as outlined in the RUPTL (Electricity Supply Business Plan) 2021-2030: (i) Fuel Substitution/Co-Firing and Renewable Energy (Moderate), and (ii) Implementation of Co-Firing, Renewable Energy, and Carbon Capture and Storage (CCS) in Fossil Fuel Power Plants (Extreme). The analysis was conducted for the 2022-2030 period, with power plant additions consistent with the RUPTL 2021-2030. Results indicate that by 2030, the Moderate and Extreme scenarios can reduce emissions by 26.4% and 56.67%, respectively, from the BaU of 15.3 Million Tons.CO2. However, these decarbonization efforts require significant additional investment, ranging from 403.57 to 3,855.64 Million USD, leading to an increase in COE by 1.6% to 27.2% from BaU operations of 13,27 ₵.USD/kWh, primarily due to rising fuel prices, OPEX and CAPEX. Therefore, Penalty cost of 9.8 USD and 103.9 USD, respectively, is incurred to abate 1 metric ton of CO2 emissions. The implementation of CCSU in CFSPP and CCPP enables CO2 emission reduction of up to 86% raises COE by up to 65% from BaU. These findings are essential considerations for achieving Indonesia's National GHG emission reduction targets.
