Generation Expansion Planning by Considering Climate-Land Use-Energy-Water (CLEW) Nexus

Climate change significantly impacts people's lives. Since the declaration of Sustainable Development Goals (SDGs), the nexus of climate change, land use, energy, and water (CLEW) has attracted attention. As an archipelagic country in Southeast Asia, Indonesia was predicted to experience a significant impact of climate change. To minimize the impact of climate change, the government of Indonesia (GOI) commits to reduce greenhouse gas (GHG) emissions through the Paris Agreement. One of the plans is in the energy sector, in which 87 of existing power plants are made up of fossil fuels. According to the GOI target, renewable energy (RE) should share the national energy mix of a minimum of 31 by 2050. However, RE resources are highly dependent on the natural condition. Currently, Indonesia's long-term planning has not considered the impact of the CLEW Nexus on RE power generation. This paper reviews the generation expansion planning (GEP) method considering CLEW in Indonesia. Systematic literature review (SLR) was conducted as a methodology of the research. Based on the review results, the system dynamics method is one of the possible solutions to the generation expansion planning problems considering the CLEW nexus. © 2021 IEEE.
