Technical FAQs 4

What is Indonesia's energy storage capacity?

Indonesiaʼs total cumulative installed energy storage capacity has reached around 35 MWh by mid-2024, primarily from BESS installations in distributed, isolated systems supporting solar PV generation. Installed energy storage capacity could exceed 30 GWh by 2030, based on announced projects.

Why is battery energy storage system important in Indonesia?

However, given the challenge of Indonesia’s geological landscape, with many off-grid and remote areas, there is growing intermittency issue that hamper the development of solar and wind generation. Hence, the battery energy storage system (BESS) technologies have a critical role in the development of Indonesia’s renewable energy.

How to accelerate energy storage deployment in the Indonesian power system?

To accelerate energy storage deployment in the Indonesian power system, key actions are needed to address existing opportunities and challenges, including: Tapping into the limited but existing opportunities for deploying energy storage systems (ESS) is vital for expanding their role in Indonesiaʼs power sector.

What is thermal energy storage in Indonesia?

While no large projects exist in Indonesia, regional interest is growing. Thermal energy storage (TES) stores energy in the form of heat (or cold). Common approaches include molten-salt tanks, phase-change materials, or hot water/steam reservoirs.
