The Institute for Essential Services Reform (IESR) assesses that Indonesia has the opportunity to transform from a country dependent on fossil fuels to a leader in renewable energy in Southeast Asia.

IESR Chief Executive Officer (CEO) Fabby Tumiwa stated in Jakarta on Monday that this is because Indonesia has a technical potential of approximately 7.7 terawatts (TW) of solar energy to provide reliable and competitive electricity to support green economic growth and quality electrification.

“This transformation requires transparent governance, a clear roadmap, competitive procurement, independent oversight, and strengthened institutional capacity,” said Fabby.

In the study “The Solar Archipelago: Indonesia’s 100 GW Leap to Energy Sovereignty” by IESR and the Coordinating Ministry for Economic Affairs, several important steps are highlighted to achieve this transformation.

One of them is through the initiative to build a 100 gigawatt (GW) solar power plant (PLTS) and battery energy storage system (BESS).

In addition to highlighting the estimated financing needs of approximately US$70 billion over five years, the study also outlined the need for cross-ministerial/institutional coordination, support from banks and green financing, and private sector participation.

Fabby assessed the need for workforce capacity building, including installation, operation, and maintenance (O&M) personnel, as well as the involvement of training centers in various provinces to strengthen capacity. Head of IESR Energy System Modeling and Analysis Alvin Putra Sisdwinugraha said, in the first phase, 26 GW of decentralized solar power plants were identified that were combined with BESS originating from government programs.
