Indonesia Office Building Energy Storage Project
This project combines solar energy generation with battery storage to provide a steady supply of electricity. The facility spans 87 hectares in Nusantara, Indonesia. It includes a 50-megawatt solar farm and a battery energy storage system (BESS) with a capacity of 14.2 megawatt-hours. [pdf]FAQS about Indonesia Office Building Energy Storage Project
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.
What is Indonesia's energy storage capacity?
Indonesia’s energy storage capacity is only 25 megawatt-hours (MWh), most of which comes from private initiatives. 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.
Will Indonesia deploy 100 GW of solar?
The Indonesian government has revealed a new initiative aiming to deploy 100 GW of solar. The distributed solar for energy self-sufficiency program encompasses 80 GW of solar that will be deployed as 1 MW solar arrays with 4 MWh of accompanying battery energy storage systems (BESS).
Does Indonesia have a grid-connected energy storage system?
There, the global system integrator Fluence recently turned on a 20MW/20MWh grid-connected BESS as part of a 1,000MW portfolio in development and construction for power company SMC Global Power. Indonesia’s current pipeline of energy storage projects is mostly pumped hydro, totalling 4,063MW according to IHS Markit.
Does Indonesia need battery storage?
Indonesia aims to convert 250MW of diesel-generated power to renewable energy this year and will need battery storage to do this successfully. Image: PLN. Indonesia’s state-owned utility and battery producer have launched a 5MW battery energy storage system (BESS) pilot project as it seeks to move away from diesel-generated power.
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.

Energy storage device for Australian office building
Underground storage of compressed hydrogen or compressed air can deliver backup and firming supply, account for seasonal changes in load and provide strategic reserves of energy to call on if there is a risk of system outage. Compressed hydrogen has very high energy density. [pdf]
