Indonesia's Electricity Supply Business Plan (RUPTL 2025-2034) identifies battery energy storage systems (BESS) as crucial for power grid reliability and integrating renewables, requiring scaled investment from both public and private sectors. Private financing and adaptive business models are key to overcoming current funding constraints of state utility PLN and mobilizing BESS deployment nationwide.

This Wire brief sits within Fusion42's coverage of Climate Tech.

◆ The Wire takeaway

You face a rare opportunity to lead in Indonesia’s power sector by designing finance models that bypass PLN’s budget limits. This opens a broad market for private battery storage projects requiring scalable investment and tailored contracts.
