Indonesian energy storage plant

Will Indonesia build a 100 GW solar power plant?

Jakarta, August 7, 2025 – Indonesia will build a 100 Gigawatt (GW) Solar Power Plant (PLTS). The program plans to build 80 GW of solar power plants and 320 GWh of Battery Energy Storage System (BESS) to be managed by the Merah Putih Village Cooperative (KDMP) in 80,000 villages, and 20 GW of Centralized solar power plants.

Can solar power plants be used in Indonesia?

Indonesia possesses solar energy potential with a capacity ranging from 3,300 GW to 20,000 GW, spanning from Sabang to Merauke. With increasingly affordable, modular, and easy-to-build and operate solar power plant (PLTS) technology, this project could serve as a strategic solution to provide reliable and affordable energy access across Indonesia.

What is Indonesia's potential for solar energy?

Indonesia’s technical potential for solar ranges from 3,300 GW to 20,000 GW, according to IESR estimates, while the country’s long-term energy policy targets up to 108.7 GW of solar by 2060. If implemented effectively, the program could redefine Indonesia’s energy landscape and serve as a global benchmark for large-scale distributed renewables.

What is Indonesia's largest solar plant?

By the end of 2023, Indonesia commissioned its largest solar plant, the floating PV PLTS Cirata in West Java, with a capacity of 145 MW (Sukmawan et al., 2015).

Why do Indonesian batteries need a battery energy storage system?

Batteries are required to provide constant electricity supply to renewable energy plants, which are primarily intermittent, such as solar and wind power plants. The agreement was made with other state-owned bodies, such as the Indonesian Battery Corporation, to build the Battery Energy Storage System by 2022.

How complex is Indonesia's energy landscape?

The Java-Bali system, contributing 75 % of national electricity generation, exemplifies the complexity of Indonesia's energy landscape (Ministry of Energy and Mineral Resources Indonesia, 2020a).
