Indonesia’s Minister of Energy and Mineral Resources Bahlil Lahadalia said on September 22, 2026, in Tangerang, Banten, that the government is preparing a revision of PT PLN (Persero)’s Electricity Supply Business Plan (RUPTL) 2025-2034 to accommodate a planned 100 gigawatt-peak solar program. PLN has submitted proposed changes covering more than 50 GWp of solar capacity and 142 GWh of battery storage, which would reshape procurement plans in Southeast Asia’s largest power market.
Key Facts At A Glance
- Energy Minister Bahlil Lahadalia confirmed on September 22, 2026, that the RUPTL 2025-2034 will be revised to accommodate the 100 GWp solar program.
- Bahlil said the program requires a regulatory basis before it can be implemented.
- PLN’s submitted revision covers more than 50 GWp of solar and 142 GWh of battery energy storage systems.
- The RUPTL approved in May 2025 set 69.5 GW of capacity additions, including 17.1 GW of solar.
- Bahlil said the RUPTL targets a 70 percent renewable share and 100 gigawatts of additional capacity.
- PLN said national electricity infrastructure plans include a 48,000 circuit-kilometer transmission network.
- The announcements were made at Enlit Asia and MKI Electricity Connect 2026 at ICE BSD City.
Indonesia’s Ministry of Energy and Mineral Resources is still preparing a revision of PT PLN (Persero)’s Electricity Supply Business Plan (RUPTL) to accommodate the planned development of 100 gigawatt-peak (GWp) of solar power plants, Minister Bahlil Lahadalia said after attending Electricity Connect 2026 in Tangerang, Banten, on Tuesday, September 22, 2026. The revision covers the RUPTL 2025-2034 and is being prepared together with PLN as the government seeks to accelerate procurement of solar power plants of up to 100 GWp.
Bahlil said the RUPTL adjustment is needed so that the solar development program has a clear planning and regulatory basis. He said the revised RUPTL will serve as the foundation for both the 100 GWp solar program and the energy transition, adding that the program cannot proceed without supporting rules.
PLN’s Proposed Changes
PLN President Director Darmawan Prasodjo said the revision PLN has submitted changes planned additions of solar power and battery energy storage systems, amounting to more than 50 GWp of solar and 142 GWh of BESS. Those figures differ from the RUPTL 2025-2034 approved in May 2025, which set capacity additions of 69.5 GW, comprising 42.6 GW of new and renewable energy, 10.3 GW of energy storage and 16.6 GW of fossil-fuel generation, with solar allocated 17.1 GW.
The available reporting does not state when the revised RUPTL is expected to be finalized, and it gives the proposed solar figure only as more than 50 GWp. Publicly available details of the revision therefore remain limited.
Targets Stated At The Forum
Speaking at the opening of Electricity Connect 2026, Bahlil said Indonesia would remain consistent in pursuing its net-zero emissions target for 2050 to 2060, and that the RUPTL is pushing for a 70 percent new and renewable energy share and the addition of 100 gigawatts. He also stressed mutually beneficial cooperation that prioritizes domestic components. Darmawan said national electricity infrastructure development includes large-scale generation additions through the RUPTL as well as construction of a transmission network spanning 48,000 circuit kilometers.
The solar target traces to remarks by President Prabowo Subianto at the Indonesia-Japan Business Forum in Tokyo on March 30, 2026, where he said Indonesia aims to reach 100 gigawatts of solar energy within three years. Prabowo cited geopolitical uncertainty in the Middle East as a strategic risk to national energy security.
Bahlil opened Enlit Asia and MKI Electricity Connect 2026 at the Indonesia Convention Exhibition, BSD City, on September 22, 2026. The event ran under the theme “Powering Regional Sovereignty, Securing Energy Systems Resilience.”
