47 Coal Power Plants Implement Biomass Co-Firing to Reduce Emissions

The Ministry of Energy and Mineral Resources (ESDM) recorded that as of October 2025, 47 coal-fired power plants (PLTU) in Indonesia have implemented biomass co-firing technology, which involves mixing biomass—such as wood and palm waste—into the coal combustion process. This technology aims to reduce carbon emissions and increase the share of renewable energy without the need to build new power plants. A total of 1.8 million tons of biomass have been used, generating 1.87 million MWh of electricity, with a biomass utilization ratio of 3.36%.

PT PLN Energi Primer Indonesia targets to expand co-firing to 52 power plants by the end of 2025 and increase biomass usage to 3 million tons. The biomass comes from previously unused industrial and agricultural waste, including sawdust, wood chips, and plantation waste. PLN is also developing a biomass supply ecosystem based on community and industry partnerships to ensure long-term sustainability. This initative is expected to significantly boost green electricity production and contribute to carbon emission reductions in Indonesia’s energy sector.
