Indonesia has set a clear course toward a greener future with the release of PLN’s 2025–2034 Electricity Supply Business Plan (RUPTL). The roadmap outlines how the country will meet growing electricity demand while accelerating its energy transition, with 76% of new capacity coming from renewables and over IDR 2,900 trillion (~USD 176.90 billion)* in planned investments. For developers and investors, the Indonesia RUPTL 2025-2034 is a call to act. It opens the door to large-scale private sector participation, but it also raises a critical question:
What will it take to move a project forward in this new energy era?
The Bold Vision of Indonesia RUPTL 2025–2034
Indonesia’s energy plan targets 69.5 GW of new generation capacity over the next decade. Solar power leads the expansion, supported by hydropower, wind, and geothermal. Fossil fuels play a smaller role in maintaining grid reliability as the country moves toward net zero by 2060.
Key highlights include:
- 17.1 GW of solar power — the largest share of new capacity
- Expansion of hydropower, wind, and geothermal
- Battery energy storage systems (BESS) and pumped hydro to support grid stability
- A national goal of electricity access for all villages by 2029
- Over IDR 2,900 trillion (~USD 176.90 billion)* in investment opportunities, open to local and international players
A Phased Rollout with a Clear Direction
The RUPTL rollout follows a two-phase strategy to balance near-term reliability with long-term sustainability:
- Phase 1 (2025–2029):
Mix of sources, including 12.2 GW from renewables, 9.2 GW from gas, 3 GW from energy storage, and 3.5 GW from coal projects already underway
- Phase 2 (2030–2034):
Strong shift toward clean energy with 30.4 GW from renewables, 7.3 GW from energy storage, and only 3.9 GW from fossil fuels
The direction is clear: renewables will dominate, and readiness will be key to moving projects forward.
New Avenues for Investment and Growth
The RUPTL presents IDR 2,967.4 trillion (~USD 181.02 billion)* in total investment potential, broken down as:
- Power generation: IDR 2,133.70 trillion (~USD 130.16 billion)*
- Transmission: IDR 565.30 trillion (~USD 34.48 billion)*
- Distribution, smart grids, and supporting infrastructure: IDR 268.40 trillion (~USD 16.38)*
Clean energy dominates private investment, with 86% of IPP funding (IDR 1,341.8 trillion or ~USD 81.85 billion) allocated to renewables. The plan is also expected to create over 1.7 million new jobs, particularly in the engineering, construction, and clean energy sectors.
Infrastructure to Support the Transition
To deliver electricity from remote renewable sources to demand centers, PLN plans to build over 47,000 km of transmission lines and 108,000 substations.
For the first time, the utility is opening transmission development to private sector participation — creating new opportunities in infrastructure and grid support services.
What This Means for Developers
1. Speed matters, but so does compliance.
Delays in permitting, land acquisition, or environmental approvals could cost months (and millions). The RUPTL may be visionary, but execution hinges on meeting environmental and social standards early.
2. Sites will get more complex
The push toward floating solar, remote hydro, and grid expansion will challenge project teams on spatial planning, biodiversity, and community impact.
3. Transmission will become the new frontier
Many renewable-rich locations sit far from demand centers, requiring smart, coordinated planning between generation and transmission infrastructure and their environmental studies.
Innovation and Access at the Core
To manage the intermittency of renewables, the plan includes:
- 4.3 GW of pumped storage hydropower
- 6.0 GW of BESS capacity
At the same time, the government remains committed to universal electricity access by 2029, requiring both major grid expansion and off-grid renewable solutions for remote areas.
Nationwide Growth, Not Just in Java
The RUPTL emphasises geographic balance, spreading development across major regions:
- Java-Madura-Bali: 33.5 GW
- Sumatra, Sulawesi, Kalimantan, and Eastern Indonesia: 36 GW combined
This opens the door for projects beyond Java, especially in regions where renewable potential and infrastructure needs converge.
Final Thoughts
The Indonesia RUPTL 2025-2034 is more than a planning document. It’s a signal of where Indonesia’s energy priorities are headed and what it will take to keep up. For developers and investors, the opportunity is significant, but so are the expectations around readiness, compliance, and long-term impact.
ESC has been actively facilitating the energy transition across Asia, supporting over 23 GW of renewable energy projects to date. Since 2003, we’ve delivered services ranging from EIA/AMDAL, ESHIA, and ESDD to scoping studies, EMMPs, ESAPs, site remediation, stakeholder engagement, and more. Our work enables project teams to move forward with confidence, grounded in local knowledge and aligned with international expectations.
