Jakarta/Belém. State electricity provider PT PLN (Persero) reaffirmed its commitment to accelerating a just energy transition through concrete action and global collaboration. At the 30th Conference of the Parties (COP30) on Monday, Nov. 10, in Belém, Brazil, PLN took an active role in a CEO Talk session titled “Corporate Climate Leadership for Indonesia’s Net Zero Action through High Integrity Carbon.”

During the forum, PLN’s Director of Technology, Engineering, and Sustainability, Evy Haryadi, said the company’s 2025–2034 Electricity Supply Business Plan (RUPTL) will be far greener than previous editions.

“In the earlier RUPTL, we were planning to build around 21 gigawatts (GW) of renewable energy. Now, that capacity has increased to roughly 52.9 GW (including storage) for the 2025–2034 period,” Haryadi said.

In addition to expanding New and Renewable Energy (NRE) generation, PLN is also working to reduce emissions from its existing power plants. This effort includes active participation in Indonesia’s emissions trading scheme, which has become a key pillar of PLN’s phased and sustainable decarbonization strategy for the power sector.

“Beyond emissions trading at existing plants, PLN is also developing various carbon financing mechanisms as innovative funding sources to accelerate the energy transition. This approach is expected to attract more green investment and help build a low-emission electricity system,” Haryadi explained.

These efforts run in parallel with PLN’s development of a Smart Grid, which enables the broader integration of renewable energy into the national power system in an efficient and reliable manner. Haryadi noted that the Smart Grid is essential to accommodate higher levels of variable renewable energy (VRE).

Indonesia’s energy transition strategy is not only focused on expanding renewable capacity but also on ensuring the system’s readiness to absorb, distribute, and balance the increased supply of clean electricity. This approach, known as Complementing Renewable Expansion, emphasizes that renewable growth must be accompanied by simultaneous investment in supporting infrastructure.

“Our Complementing Renewable Expansion strategy is designed to ensure renewable expansion progresses alongside system enhancements, including greater storage capacity, flexible gas- and hydro-based power generation, and the development of inter-regional green transmission networks,” he added.

Under this strategy, PLN will increase investment in energy storage systems, flexible power plants, and more robust inter-island transmission infrastructure. The goal is to integrate renewable energy optimally without compromising reliability or electricity affordability. This approach also paves the way for renewable energy to account for more than 75 percent of Indonesia’s power mix within the next decade.

Haryadi further emphasized that PLN’s renewable energy expansion has the potential to generate up to 250 million tons of emission-reduction certificates. This, he said, is not only about meeting regulatory requirements but also about creating real economic value from green growth while accelerating the national energy transition.

“This green-attribute potential reflects not only PLN’s technical capabilities in clean energy development but also PLN’s role as a driver of Indonesia’s green economy. We want to ensure that every ton of emissions reduced generates tangible value for the country, investors, and society,” he said.

PLN is also aiming to exceed regulatory targets by generating additional value from its decarbonization potential. The company continues to build cross-sector collaborations and innovative financing partnerships to support its transition strategy.

“Support from international financial institutions, technology transfer, and high-integrity carbon-market mechanisms will be crucial to ensuring the acceleration of the energy transition remains inclusive and equitable,” Haryadi concluded.
