Indonesia's power sector is dominated by coal-fired generation, which supplies approximately 62% of national electricity. The sector emits an estimated 250 million tonnes of CO₂ per year making it the single largest source of industrial GHG emissions in the country. PLN's grid mix must shift dramatically to meet Indonesia's renewable energy target of 23% by 2025 and net zero by 2060. Independent Power Producers (IPPs), geothermal developers, and utilities face growing pressure from international climate finance, green bond standards, and electricity offtake buyers requiring low-carbon supply chains.

The global transition creates both regulatory risk and commercial opportunity. Coal plants face stranded asset risk as carbon pricing mechanisms advance. Meanwhile, geothermal, hydro, and biomass operators can monetize clean power credentials through carbon credits, renewable energy certificates, and green financing premiums. Indonesia's Carbon Economic Value regulation (Perpres 98/2021) is activating the domestic carbon market creating new revenue streams for low-carbon generators. Power companies that rigorously measure and report their environmental performance will be best positioned to capture this value.
