Sizing and Costs Implications of Long-Term Electricity Planning: A Case of Kupang City, Indonesia

Abstract

This paper presents long-term electricity supply-demand scenarios for Kupang City, Indonesia. The objective of the analysis is to reveal the alternatives sizing of power plants along with the power generation costs that is potentially incurred during the study period. The study is conducted using bottom-up energy model. Electricity energy in terms of supply-demand variation is taking into account both fossil fueled and renewable energy potential in the supply side, and the scheme of high as well as average electricity growth rate in the demand side. Four variations of supply-demand conditions is presented as the study result. The results has shown total energy supplied which is required in order to satisfy the usual demand growth and the total saving potential under the demand scheme. The variation in terms of costs also shown depending upon the renewable energy penetration. The study is expected to contribute towards the utilization of more renewable energy potential, particularly the possible implementation of Photovoltaic plants and the campaign of energy efficiency and conservation within the observed area.
