According to the Institute for Essential Services Reform (IESR), Indonesia’s solar energy development has been slow, with only 718 MW installed by August 2024, far below the national target of 17 GW. Indonesia needs to install 77 GW of solar PV capacity by 2030, requiring an annual rate of 9-15 GW from 2024 onwards to meet global renewable goals. Investments in solar have doubled, rising from $68 million in 2021 to $134 million in 2023, signaling growing sector confidence. The country’s annual solar module production capacity has reached 19 GW, primarily driven by exports to Singapore. According to IESR, energy storage systems remain underdeveloped but will be crucial to support solar expansion. The institute claims 2025 will be pivotal in reviewing regulatory and infrastructure readiness for large-scale adoption of solar and storage.
