In a statement issued on Friday, Minister of Energy and Mineral Resources Bahlil Lahadalia said the project will connect new and renewable energy (NRE) sources to main substations, which will then distribute electricity through local networks.
The 47,758 ckm transmission network will be developed in phases over the next decade, as outlined in the Electricity Supply Business Plan (RUPTL) of state-owned utility PLN for the 2025–2034 period.
“To connect this new renewable energy, we must build a transmission network. Our target is to reach 23 percent NRE in the energy mix, but we’re currently only at 15–16 percent. The issue is the lack of supporting infrastructure,” Lahadalia said on May 26.
The longest portion of the planned network, measuring 13,900 ckm, will lie in the Java, Madura, and Bali regions. Sumatra will have 11,200 ckm, Kalimantan 9,800 ckm, and Sulawesi 9,000 ckm. The remaining 3,900 ckm will be constructed in the Maluku, Papua, and Nusa Tenggara regions to strengthen the electricity system in eastern Indonesia.
To support this transmission network, the government also plans to build substations with a total capacity of 107,950 megavolt-amperes (MVA) nationwide.
Lahadalia noted that the project opens investment opportunities worth Rp565.3 trillion (approximately US$34.7 billion). It is expected to create more than 880,000 jobs in manufacturing, construction, operations, and maintenance of transmission lines and substations.
He emphasized that the initiative should maximize the use of local components to support economic growth and reduce import dependence.
