Biomass co-firing in coal-fired power plants is a key strategy to support national renewable energy targets. Although technically feasible, its implementation may affect boiler reliability and plant performance. This study evaluates the impact of co-firing on corrosion rate, boiler tube remaining life, Net Plant Heat Rate (NPHR), and Specific Fuel Consumption (SFC) using Two-Way ANOVA and linear regression. Results show that area/location, fuel type, and their interaction significantly affect corrosion rate and remaining life (p < 0.05). Fuel type is the dominant factor, with partial eta squared (η²ₚ) values 0.900 (Unit 1), 0.812 (Unit 2) in corrosion rate and 0.915 (Unit 1) and 0.901 (Unit 2) in remaining life. Regression analysis indicates that calorific value influences NPHR and SFC, with both positive and negative relationships depending on unit and fuel composition. Overall, the implementation of biomass co-firing has a significant impact on corrosion rate, remaining life, and changes in power plant performance. Nevertheless, co-firing remains a viable energy transition solution, provided that technical considerations and appropriate operational control strategies are properly addressed.
