The Influence of Biomass Quantity, Biomass Delivery, and Power Plant Infrastructure on the Productivity of Biomass Co-firing Electricity Production in Steam Power Plants

PLN, Indonesia’s state-owned electricity company, continues to commit and innovate towards achieving the target of 23% new and renewable energy (NRE) mix by 2025 and net zero emissions by 2060. One of its programs is the Biomass Co-firing in Steam Power Plants (PLTU), a substitution technique in combustion that utilizes biomass as an alternative to partially and/or entirely replace coal as fuel. This study aims to analyze the impact of biomass quantity, biomass delivery, and power plant infrastructure on the productivity of biomass co-firing electricity production at steam power plants. This research employs a quantitative approach. The sampling technique used is purposive sampling, with a total of 100 respondents. Data analysis was conducted using the structural equation model (SEM) with the help of SmartPLS version 4 software. The results show that biomass quantity (X1) and power plant infrastructure (X3) have a positive and significant impact, while biomass delivery (X2) has a positive but not significant effect on the productivity of biomass co-firing electricity production at steam power plants (Y). The R-Square value is 0.355. The equation model is as follows: Y = 0.352 X1 + 0.035 X2 + 0.377 X3. Practical implications include establishing long-term partnerships with industrial/energy plantation forest managers, conducting stakeholder management, and conducting power plant readiness assessments.
