ADU KLAIM MENURUNKAN EMISI

Trend Asia challenges PT PLN's claim that biomass co-firing facilitates an energy transition and reduces emissions. The report argues that the massive land requirements for energy plantation forests (HTE) to supply wood pellets would lead to significant deforestation, resulting in net carbon emissions rather than reductions. It finds that biomass has become a complement to, rather than a substitute for, coal, with total coal consumption continuing to rise.

• PT PLN claims that replacing 5-10% of coal supply with biomass in coal-fired power plants (PLTU) constitutes an energy transition to renewable sources, targeting a 23% renewable energy mix by 2025.
• Trend Asia estimates that implementing 10% co-firing across 107 PLTUs would require 10.23 million tons of wood pellets annually, necessitating energy plantation forests (HTE) covering at least 2.33 million hectares.
• The expansion of HTE is likely to cause significant deforestation; based on MapBiomas Indonesia data showing 38% of industrial forest plantations (HTI) came from natural forest clearing, the report projects high potential deforestation for various HTE species, with Gamal having the highest potential at 2,099,843 hectares.
• Mathematical modeling by Trend Asia indicates that 10% biomass co-firing in 107 PLTUs could generate total emissions between 7.9 million and 26.48 million tons of CO2e per year, depending on the tree species used.
• The report refutes the 'carbon neutral' claim of wood biomass, stating that the carbon stocks of natural forests lost during HTE construction cannot be compensated for by the carbon absorbed by the new plantations, resulting in a net emission gap of approximately 6.8 million to 11.3 million tons of CO2e.
• Biomass co-firing has not reduced coal usage; PLN's coal consumption increased from 66.68 million tons in 2020 to 68.47 million tons in 2021, while biomass use rose from 9,731 tons to 282,628 tons in the same period.
• The report concludes that co-firing is being used as a justification to extend the operational life of coal plants that should be retired, while coal demand is projected to rise from 111 million tons in 2021 to 153 million tons by 2030.
