Indonesia Solar Energy Transition Gains Momentum with $60mn JETP Support

Floating Solar Project in Java Advances Despite U.S. JETP Withdrawal

Indonesia’s solar energy transition has taken a significant step forward, with $60 million in new funding for the Saguling floating solar project. The support comes under the Just Energy Transition Partnership (JETP) and involves joint development by PLN Indonesia Power and Saudi-listed Acwa Power. Despite U.S. withdrawal from the JETP earlier in 2025, international backing continues, reinforcing Indonesia’s commitment to phasing out coal.

Multilateral Support Drives Renewable Investment

The Saguling solar project will receive financing from DEG (Germany), Proparco (France), and Standard Chartered, as announced by GFANZ. This adds to the $1.2 billion Indonesia has already secured under the $20 billion JETP framework. France has played a major role, contributing over €450 million ($511 million) in energy transition funding. According to GFANZ, this investment shows strong appetite among both public and private actors to support Indonesia’s solar energy transition.

Coal Dominates, But Solar Begins to Scale

Indonesia still relies on coal for over 61% of electricity, while solar and wind contribute only 0.2%. However, Indonesia holds solar potential of 3,295GW, and projects like Saguling are vital for unlocking that capacity. The Saguling floating solar farm will add 92MWp and reduce carbon emissions by 63,100 t/year. It will increase Indonesia’s solar share by 13%, with renewables projected to rise to 21% of the energy mix by 2030, and 41% by 2040, according to Ember.

The Metalnomist Commentary

Indonesia’s solar energy transition is proving resilient, even amid shifting geopolitical support. The latest JETP-backed investment reaffirms that international climate finance remains a critical pillar in Asia’s coal phase-out.
