Can energy storage systems be deployed in Indonesia?

Tapping into the limited but existing opportunities for deploying energy storage systems (ESS) is vital for expanding their role in Indonesiaʼs power sector. At present, the greatest potential for ESS deployment lies in smaller and/or isolated systems, as well as in industrial or large scale commercial solar rooftop PV with BESS.

Does Indonesia have a large-scale energy storage system?

His Muhammad Bintang, Author of Powering the Future 2024 and Coordinator of IESR’s Energy and Electricity Resources Research Group, said that Indonesia does not yet have a large-scale energy storage system. “The electricity export scheme to Singapore could be an opportunity to accelerate the country’s adoption of ESS.

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 does Indonesia's electricity system work?

Indonesia's electricity system can be powered predominantly by solar PV, complemented by geothermal and hydroelectric power. Off-river pumped hydro energy storage is identified as a major asset for balancing high solar energy penetration.

What percentage of Indonesia's energy comes from coal?

In 2023, Indonesia derived approximately 60% of its energy from coal, while renewable energy’s contribution is estimated at about 15%. By 2025 and 2030, the Indonesia government aims to achieve the target of 23% and 30% of renewable energy contribution into the energy mix.

How is energy used in Indonesia?

Total energy supply (TES) includes all the energy produced in or imported to a country, minus that which is exported or stored. It represents all the energy required to supply end users in the country.
