In May 2026, President Prabowo Subianto officially compressed the timeline for the nation’s ambitious 100 GW solar push from five years down to just three. Driven by the recent grid vulnerabilities, policymakers are fast-tracking the program to eliminate the state budget’s heavy exposure to volatile, multi-trillion-rupiah diesel fuel imports. State data indicates that completely swapping out inefficient diesel plants for solar and battery energy storage system (BESS) networks could save the state budget roughly IDR 74 trillion (approx. USD $4.1 billion), annually.
On Friday (3 July 2026), reports emerged that the government has mapped out roughly 28,000 hectares of strategic land in Java to support grid integration. Of this total, 8,500 hectares are earmarked for land-based solar arrays generating 8.5 gigawatt-peak (GWp) alongside dedicated BESS networks. To bypass the friction and high cost of land acquisition entirely (a major bottleneck on land-scarce islands like Java) the government is targeting an additional 10,000 hectares of water surfaces across state-owned reservoirs to host up to 10 GWp of floating solar power.

This pivot to floating solar is economically vital. Data from state-owned utility PLN reveals an extreme tariff sensitivity to land prices: if land costs jump from IDR 200,000 to IDR 600,000 per square meter, the resulting electricity tariff spikes by roughly 1 cent per kWh, threatening project bankability.
A major macroeconomic concern among local energy economists is that a sudden 100 GW target could turn Indonesia into a passive import market for Chinese solar components, yielding little domestic value. To counter this, the Ministry of Investment and Downstreaming confirmed that USD $1.4 billion in foreign direct investment (FDI) has been secured to establish a robust domestic solar manufacturing ecosystem, aiming for a 50 GW local production capacity. This domestic supply chain will be leveraged heavily to enforce local content requirements (TKDN) during upcoming project tenders. Notably, joint ventures like Trina Mas Agra Indonesia in the Kendal Industrial Park have already begun operations with an initial TKDN baseline of 41 percent.
Concurrently, the Ministry of Energy and Mineral Resources is finalizing a dedicated Presidential Regulation (Perpres) tailored to eliminate bureaucratic inertia. The upcoming framework focuses on:
- Streamlining multi-ministry land clearing across the Ministry of Agrarian Affairs and Spatial Planning/National Land Agency, the Ministry of Environment, and PLN.
- Standardizing accelerated, transparent tender processes to attract international private developers.
- Clarifying long-term off-taker agreements and funding structures backed by the Danantara sovereign wealth framework.
The massive momentum behind the 100 GW infrastructure rollout has also turned into a significant catalyst for publicly listed companies with direct exposure to the renewable energy space, most notably Dian Swastatika Sentosa and Kencana Energi Lestari.
Dian Swastatika Sentosa has expanded well beyond its traditional commercial and industrial rooftop photovoltaic (PV) footprint via its subsidiary, Daya Mas Agra Sejahtera. Through Trina Mas Agra Indonesia (a high-tech manufacturing joint venture with Trina Solar and PLN Indonesia Power Renewables) the company has positioned itself at the vanguard of local solar cell and panel fabrication.
Meanwhile, Kencana Energi Lestari continues to scale its green footprint. The company currently operates two solar power facilities in Bangka Belitung totaling 5.46 MWp, complete with active battery storage solutions. Looking ahead, the company boasts a robust long-term development pipeline targeting an additional solar capacity of more than 60 MW.
