IEEFA highlights Indonesia’s renewable energy and supply chain opportunities at the Mandiri Investment Forum

Indonesia can maximize renewables and battery technologies as the best investments to hedge against the volatile energy and dollar markets, said Grant Hauber, Strategic Energy Finance Advisor for Asia at the Institute for Energy Economics and Financial Analysis (IEEFA), during the 2025 Mandiri Investment Forum.

Senior Indonesian government officials, foreign institutional investors, and global experts recently attended the Forum in Jakarta, co-hosted by Bank Mandiri and Mandiri Sekuritas. Hauber’s session, "Fueling Innovation: New Directions in Energy Policy," included panelists from the leadership teams of the national utility PT Perusahaan Listrik Negara (PLN), Pertamina, and SKK Migas.

“This is an opportunity to show what is possible for Indonesia under the newly formed government: renewables technologies, energy efficiency, and electrification are great economic levelers that provide affordable investment opportunities,” said Hauber.

IEEFA’s report showed that this is especially true for solar energy since Indonesia’s current energy plan has the region’s fewest near-term planned solar additions despite its substantial solar generation potential.

“You can add hundreds of megawatts of solar in six to 12 months, not years, and we've seen countries throughout the region take advantage of this,” said Hauber.

However, to further leverage international cooperation and private investments, clear and efficient processes need to be established to attract the vast sums of capital needed for Indonesia to achieve a successful transition.

IEEFA’s commentary also highlighted that implementing an investment program that delivers multiple gigawatts of projects year-on-year for over a decade requires a fresh approach.

“For Indonesia to create an environment that welcomes renewables investments, implementing procurement protocols and bidding processes that are consistent, fair, and transparent are crucial,” said Hauber.

Responding to a question from the attending dignitaries, Hauber commented that President Trump's recent signing of the withdrawal order for the Paris Agreement should not deter other countries.
