Harnessing Biomass, PLN IP Produces 1,101.59 GWh of Clean Energy Over the Course of 2025

PLN Indonesia Power (PLN IP) has recorded biomass-based clean energy production of 1,101.59 GWh over 2025. This output rose 16 percent compared with 2024. Chief Executive Bernadus Sudarmanta said the achievement results from optimising the implementation of the biomass co-firing programme at all steam power plants (PLTU) managed by the company. Biomass co-firing involves mixing biomass with coal as a fuel at steam power plants (PLTU). This technology enables a reduction in the use of fossil fuels at PLTU. He explained that the clean energy production was achieved through utilisation of 1,140,253 tonnes of biomass sourced from various agricultural and industrial wastes. These include sawdust, palm kernel shells, empty fruit bunch pellets, rice husk, woodchip, wood pellet, corn cob, banknote processing waste, as well as solid briquette fuels. He said the use of biomass also strengthens the circular economy principle by converting waste into an energy source that is more environmentally friendly. Parallelly, the co-firing implementation makes a significant contribution to reducing carbon emissions. By the end of 2025, PLN IP managed to reduce emissions by 1,259,696 tonnes of CO2 avoided, or a 16 percent increase from 2024. This step forms part of the company’s support for national emission reduction targets and increasing the share of renewable energy sources (EBT). Bernadus added that the biomass utilisation strategy not only affects the environmental aspect but also adds economic value through strengthening the domestic supply chain and empowering the agriculture sector and the waste processing industry. ‘Going forward, PLN IP will continue to increase the scale and quality of co-firing implementation as part of the corporate energy transition roadmap,’ he said.
