Investor Daily - PLTU Jeranjang serap 150 ton biomassa
19 May 2025
Jakarta, ID – Biomass products derived from wood waste are gradually reducing coal consumption at the Jeranjang Coal-fired Power Plant (PLTU) in West Lombok, West Nusa Tenggara.
The Business Unit Manager of PLTU Jeranjang, Yunisetya Ariwibawa, stated that in a trial conducted in 2019, only 5 tonnes of biomass were used over a month. However, the current average biomass consumption has exceeded 150 tonnes daily.
“That amount will certainly increase as we adjust to meet our annual target,” Ariwibawa said, as quoted by the news agency Antara in Jakarta last weekend.
In 2024, the target for biomass utilisation at PLTU Jeranjang was set at 28,675 tonnes, with a target measurement unit from green energy sources, or MWh green, amounting to 22,940 megawatt-hours. The actual biomass consumption reached 29,009 tonnes, with realised MWh green recorded at 25,043 megawatt-hours.
Meanwhile, the biomass consumption target for 2025 is 35,200 tonnes, with MWh green amounting to 28,847 megawatt-hours. As of 13 May 2025, the realised biomass consumption at PLTU Jeranjang stands at 14,621 tonnes, with the realised measurement unit from green energy sources reaching 11,021 megawatt-hours.
Ariwibawa explained that the implementation of biomass utilisation by Perusahaan Listrik Negara (PLN) through the co-firing programme helps reduce emissions generated from coal combustion while assisting the community in managing organic waste.
“Co-firing is highly beneficial, especially in terms of environmental impact, as it is non-carbon, thus reducing emissions from the PLTU. This is certainly better compared to fully relying on coal,” he remarked.
PLTU Jeranjang currently uses biomass in a relatively small proportion, accounting for only 10 percent of the total coal fuel needed to operate the power plant. The biomass raw materials, including sawdust and woodchips, are sourced from four local suppliers.
