Indonesia's state-owned electric utility company, PT PLN (Persero), plans to build a 1.4 GW hybrid power plant combining mine-mouth coal-fired steam power (PLTU), solar power (PLTS), and battery energy storage (BESS) in Sumatra and Kalimantan, as outlined in the RUPTL 2025–2034. Two 600 MW hybrid PLTU units are planned for Sumatra, scheduled for operation in 2032 and 2033, while Kalimantan will host a 200 MW unit by 2032. Although new PLTU projects are banned under Presidential Regulation 112/2022, PLN argues this plan qualifies for exemptions, as it was included in the RUPTL before the regulation and commits to reducing greenhouse gas emissions by 35% within 10 years. The government is revising Presidential Regulation 112/2022 to encourage investment and accelerate renewable energy targets, including rules for hybrid plants. Critics, however, warn that the broad definition of hybrid PLT could allow fossil energy projects to continue under the “hybrid” label, potentially undermining the energy transition. PLN maintains the project is necessary to meet rising demand from high-voltage consumers in Sumatra and Batam-Bintan, estimating an additional 1,744 MVA load starting in 2032. The debate reflects Indonesia’s balancing act between energy security, industrial demand, and its renewable energy commitments.Source: https://katadata.co.id/ekonomi-hijau/energi-baru/69b3998d84639/menilik-rencana-1-4-gw-pltu-hibrida-di-sumatra-dan-kalimantan (ICE GIACARTA)
