Indonesia launches 100 GWp solar push to draw global investors

Indonesia has launched a 100 gigawatt peak solar program and is using Climate Week NYC to court international capital for the first 5.3 GWp in projects now underway. Industry leaders say clear rules, faster permitting and investable project pipelines will determine whether the country can turn the plan into bankable opportunities.

Why it matters: - Indonesia is trying to convert its solar potential into a large-scale investment market. - The 100 GWp program could open opportunities across utility-scale solar, rooftop systems, storage, manufacturing and corporate power procurement. - Clearer policy and project visibility are being positioned as the key to attracting foreign capital.

What happened: - President Prabowo Subianto launched Indonesia’s 100 gigawatt peak solar power program in August. - The first phase includes 14 solar projects totaling 5.3 GWp. - The projects are targeted for development over the next three years. - The pitch to investors was made at the Indonesia Solar Investment Forum 2026: “From Ambition to Investable Scale” during Climate Week NYC at the Consulate General of Indonesia in New York. - The forum was hosted by the Asosiasi Energi Surya Indonesia (AESI), the Indonesia Investment Promotion Center (IIPC) New York, Tenggara Strategics and SANARA.

The details: - Yoga Adhi Pratama, deputy director of IIPC New York, said Indonesia needs to present its solar buildout as a pipeline of defined projects with assessable risks and commercial terms. - Yoga said investment promotion can connect global investors with project developers and relevant institutions to convert interest into investment decisions. - Mada Ayu Habsari, chairperson of AESI, said the 100 GWp target requires redesigning the delivery system. - AESI is pushing a single billing platform through PLN and broader access for government buildings and residential users. - AESI has mobilized four task forces to work with the government on the national roadmap. - AESI highlighted three urgent regulatory priorities: finalizing a new Presidential Regulation, publishing a multi-year project pipeline and opening more demand-side access. - The new Presidential Regulation is undergoing inter-ministerial harmonization and is expected to cover all solar segments. - The regulation is expected to provide a clear calendar, offtake certainty and local content guidelines. - Investors want a published schedule showing which projects will be tendered and when they will reach commercial operation. - AESI is proposing an adaptive quota review based on actual grid capacity and differentiated rules for solar systems paired with battery storage. - AESI says approval processes and quota regulations are currently slowing rooftop solar growth. - Mada said AESI is recommending clear timelines for Ministerial Decree No. 2. - The proposal calls for a three-month quota process for systems below 500 kWp and six months for larger systems. - AESI wants quota restrictions removed eventually as the market matures. - AESI is also pushing a single billing scheme through PLN to simplify consumer access to clean power. - Solar generation, grid transmission and battery energy storage systems need synchronized planning to avoid wasted energy and lower capital costs. - AESI identified four areas where international collaboration could produce near-term results: value-chain development, project preparation standards, risk mitigation instruments and corporate procurement. - Indonesia is seeking partners for technology transfer to manufacture solar cells, inverters and battery systems domestically. - Development finance institutions can help set feasibility and governance standards for the first tranche of projects. - Guarantees, credit enhancements and currency hedging tools are being sought to reduce perceived country risk. - Expanding renewable electricity procurement by multinational corporations in Indonesia could create a demand segment requiring little public capital. - Tessal Febrian, director at IIPC New York, said the center can help investors understand available incentives and facilitation for priority projects, including renewable energy. - Tessal said Government Regulation No. 28 of 2025 streamlines business licensing, accelerates industrial development and improves investor services. - Indonesia also offers fiscal incentives for green investments, including tax allowances, import duty exemptions and super tax deductions. - Tessal said investor input is still needed as solar policy develops.

Between the lines: - Indonesia is not just selling a power target. It is trying to sell a rules-based investment case. - The emphasis on project sequencing, licensing speed and quota reform suggests the market has potential but still faces execution bottlenecks. - The focus on battery storage, local manufacturing and corporate procurement points to a broader industrial strategy, not only a renewable buildout.

What's next: - AESI and the government are expected to keep refining the regulatory framework for solar deployment. - The new Presidential Regulation will be a key signal for investors once harmonization is complete. - Project visibility, quota rules and PLN billing reforms will likely shape how quickly the first 5.3 GWp moves forward. - Further collaboration with development finance institutions and multinational buyers could help scale financing and demand.
