Bali Leads Indonesia's 100 GWp Solar Push
For an island that markets itself on natural beauty and spiritual harmony, Bali has carried an awkward secret: much of its electricity has come from diesel-fired power plants. That contradiction may finally be on its way out. On August 25, 2026, President Prabowo Subianto launched a national program to develop 100 gigawatt-peak (GWp) of solar power capacity, and he chose Gilimanuk, in Bali's Jembrana District, as the site for the ceremony.
The choice was deliberate. Bali received the largest single allocation in the program's first phase: 1 GWp out of a combined 5.3 GWp planned across 14 solar plants in six provinces. According to state electricity company PLN, the Gilimanuk solar plant is projected to reduce diesel fuel consumption by up to 0.6 kiloliters, a meaningful step for a grid that has long leaned on fossil fuels.
How the Decision Came Together
The speed of the allocation surprised many observers. Energy and Mineral Resources Minister Bahlil Lahadalia, Bali Governor Wayan Koster, and PLN President Director Darmawan Prasodjo held a working discussion on the evening of August 22. President Prabowo approved the proposed quota the following day, and the national launch followed two days after that. For a country whose infrastructure approvals are often associated with lengthy bureaucratic processes, the timeline was notable.
Governor Koster has set a target of transitioning Bali entirely to new and renewable energy by 2030. The 1 GWp allocation, as reported by Antara, is described as the missing piece in that plan, complementing existing efforts around waste management and environmental conservation.
The Bigger Economic Picture
The 100 GWp program is not purely an environmental initiative. The Indonesian government projects that achieving the full target would substitute between US$14.4 billion and US$28.9 billion in energy imports, add US$26.6 billion to GDP, create 5.5 million jobs, and cut annual energy subsidy costs by more than Rp73.9 trillion (over US$4 billion). Total potential investment is estimated at Rp1,140 trillion, roughly US$62 billion.
President Prabowo set a 2029 deadline for the full 100 GWp target, a figure that would more than double Indonesia's current total power-generating capacity of 88 GWp from all sources combined. PLN has incorporated the program into its 2025 to 2034 Electricity Supply Business Plan, with a near-term target of 17 GW of solar generation supported by facilities on 24,000 hectares across Java.
Indonesia's energy projects have historically seen targets revised over time, and the distance between a groundbreaking and full delivery at this scale is considerable. Land availability, supply chain readiness, transmission infrastructure, and sustained funding will all need to align. Still, the inclusion of the program in PLN's formal planning document gives it more institutional weight than a ceremonial announcement alone would carry.
Why It Matters for Hosts
Independent accommodation and hospitality operators in Bali have long dealt with the costs and reliability issues that come with a diesel-dependent grid, including fuel surcharges and occasional outages. If the Gilimanuk plant delivers on its timeline, properties across the island could benefit from a cleaner, more stable electricity supply within the next few years. Hosts who are already investing in rooftop solar or energy-efficiency upgrades will be well positioned to communicate a genuine sustainability story to guests, one that is now backed by national infrastructure rather than individual effort alone. Tracking PLN's construction milestones and the Bali government's 2030 renewable energy roadmap is worth adding to any operator's planning calendar.
