How should energy storage systems be planned in Indonesia?Planning for energy storage systems should be well integrated with power transmission, distribution, and generation planning in Indonesia, aligning with the increasing installation of VRE. Besides setting capacity targets, planning documents should outline the full range of potential ESS roles.
How many solar-plus-storage mini grids will be installed in Indonesia?These solar-plus-storage mini grids are set to be installed in 80,000 villages across Indonesia and will be managed and operated by village cooperative Merah Putih. A target of 10,000 becoming operational by August 2025 has been set.
Does a super grid reduce energy costs in Indonesia?The super grid reduces costs slightly, with notable cost reductions in scenarios involving lower RE and energy storage costs. The average cost of energy across Indonesia is around USD 90/MWh, with the super grid scenario showing a slight reduction in generation costs.
Is Indonesia ready to absorb more renewables?As the Oliver Wyman study notes, neither Indonesia’s grid nor its storage infrastructure is currently ready to absorb significantly more renewables. Long-Duration Energy Storage (LDES) is crucial for balancing supply and demand over days and seasons, enabling a reliable supply of Indonesia renewable energy.
Can gravity storage accelerate Indonesia's transition to a clean and reliable power system?By harnessing robust gravity storage and researching sustainable storage technologies, Indonesia can accelerate its transition to a clean, reliable power system.
