Optimization and Emission Reduction Analysis Using Hybrid PLTD-PLTS Technology in the Wangi-Wangi Diesel Power Plant
Keywords:
Hybrid PLTD-PLTS, Life Cycle Assessment, Emission Reduction, Energy Optimization, HOMERAbstract
The transition to cleaner and more sustainable energy sources presents a major challenge in the power sector, particularly in remote areas that still rely on Diesel Power Plants (PLTD). While PLTD offers operational reliability, it also has significant drawbacks, including high fossil fuel consumption, large operational costs, and substantial carbon emissions. Therefore, integrating PLTD with Solar Power Plants (PLTS) in a diesel-hybrid system emerges as a potential solution to optimize energy efficiency and reduce environmental impact. This study aims to analyze the optimization and emission reduction of diesel-hybrid technology at PLTD Wangi-Wangi using the Life Cycle Assessment (LCA) approach with a Gate-to-Gate system boundary. The analysis is conducted using HOMER for technical hybrid system simulation and assess environmental impacts, particularly in terms of CO₂ emissions. This research evaluates different energy mix scenarios, namely 30%, 50%, and 70% PLTS penetration, to determine the potential fuel consumption reduction and its impact on system stability. With the right strategy, implementing a PLTD-PLTS hybrid system can be a viable solution for decarbonization and energy resilience, especially in island regions like Wakatobi.
