The Role of Renewable Energy Resources in Generation Expansion Planning and GHG Emission Reduction: A Case Study of West Papua

Abstract

The impact of the implementation of the renewable energy power plant to GHG emission has been analyzed in this study. Four types of the renewable power plant have been simulated in the model which are hydro, biomass, solar, and wind power plant. The bottom-up model has been developed to conduct the analysis. In the developed model, two scenarios have been generated. BAU scenario represents power system expansion planning without any renewable power plant. On the other hand, the RPP scenario represents the role of renewable power plant in the system. Contribution of renewable power plant has been analyzed in two aspects which are contribution to the production of electricity and to the reduction of GHG emission. The model has been implemented using LEAP software combined with the optimization solver. The comparison of two generated scenario is summarized as cost-benefit analysis. The result showed that the implementation of renewable energy power plant reduced GHG emission by 43.38% cumulatively with the contribution of generated electricity by 42.62%. Cost-benefit analysis shows that the implementation of the renewable energy power plant produces NPV of 47.10 Million USD less than the BAU scenario.
