Key facts
- Celios estimated the 100 GWp solar program needs about $73 billion, or roughly IDR 1,277 trillion, for 2026 to 2030.
- About 80% of the program's financing need falls between 2027 and 2029, per the Celios report.
- Celios said coal, oil and gas revenue after regional transfers could reach about IDR 658 trillion over the same period.
- A renewable envelope within Danantara could supply about IDR 129 trillion, around 10% of the program's needs, the report said.
- The PRAKARSA researcher Dea Fajria Tatarizqa Japal said installed solar capacity was about 1.5 GWp at the end of 2025.
- The 2025 to 2034 electricity supply plan requires about $190 billion of investment, MPR Deputy Speaker Eddy Soeparno said.
Indonesia's 100-gigawatt solar program needs about $73 billion, or roughly IDR 1,277 trillion, for 2026 to 2030, with about 80% of that spending falling between 2027 and 2029, according to a report published on November 9, 2026 by the Jakarta-based Centre of Economic and Law Studies (Celios). The report said Chinese investment in Indonesia's energy sector was expanding beyond nickel processing and electric-vehicle battery production, and that a funding gap and demands for greater domestic control complicate the plan.
Celios estimated that central government revenue from coal, oil and gas, after revenue-sharing transfers to regional governments, could reach about IDR 658 trillion over the same period. It said a fixed fiscal recycling allocation and a renewable envelope within Danantara could direct about IDR 129 trillion, around 10% of the program's financing needs, to solar development. The report said the share of revenue allocated mattered more to financing outcomes than changes in commodity price assumptions.
The findings were discussed at a forum The PRAKARSA held with ClientEarth and the Indonesian Solar Energy Association in Jakarta on November 5, 2026. The PRAKARSA researcher Dea Fajria Tatarizqa Japal said Indonesia's installed solar capacity had reached only about 1.5 GWp by the end of 2025. MPR Deputy Speaker Eddy Soeparno told the forum that the 2025 to 2034 electricity supply plan requires about $190 billion of investment and that the solar program is estimated to need around $100 billion, with land acquisition, reservoir use for floating solar and high logistics costs among the challenges.
