The target forms the opening phase of a wider drive that President Prabowo Subianto has championed to diversify the national power mix. Officials have already designated tracts of land on Java for early development while drafting tariff structures that range from 5.5 to 25 US cents per kilowatt-hour for utility-scale projects. The programme also envisages pairing solar installations with substantial battery storage to maintain grid reliability during peak demand periods.
Current installed solar capacity stands at roughly 1.5 GW, a SAUR Energy review published on June 1, 2026 showed. That limited base follows a decade in which only 717 MW of solar photovoltaic capacity was added nationwide. The gap has prompted authorities to outline a USD 71.3 billion investment programme that would deliver around 100 GW of solar generation together with 145.8 GWh of battery storage between 2026 and 2028.
Separate electricity supply planning documents aim to bring 42.6 GW of new renewable energy online by the end of 2034, according to an Institute for Energy Economics and Financial Analysis briefing released on June 19, 2025. Solar is projected to account for the largest portion at 17.1 GW under the latest RUPTL plan that was launched on May 26, 2025. The framework supports the Golden Indonesia Vision 2045 that sets a national benchmark of 75 GW of renewable capacity in operation by 2040.
Solar currently supplies just 0.2 percent of Indonesia’s total energy needs, the Institute for Energy Economics and Financial Analysis assessment found. Meeting the 2040 goal will therefore require average annual additions approaching 5 GW across the next 15 years. Analysts have recommended a revised procurement model built around pre-cleared project sites, transparent bidding and a single credible public contracting body to accelerate private-sector participation.
An initial 13 GW solar rollout is planned as the first stage of the broader 100 GW programme to expand electricity access in rural communities, the Jakarta Globe reported in March. The Indonesia Solar Summit held from July 14 to 16, 2026, brought together regional stakeholders to strengthen the solar supply chain and policy coordination. Participants reviewed progress on prospective projects that could help the country surpass its 2030 renewable benchmarks if construction timelines are brought forward.
