In this study, we estimated the business feasibility and ripple effects on the local economy of linking a woody biomass utilization system, including trigeneration, with a workcation base facility. In this estimation, three systems (less than 500 kW scale) with different fuel types, gasification methods, and energy recovery methods were combined, and a comparison case was set up in which a workcation facilities was assumed to be installed as a heat supply destination. The results of the analysis showed that the cogeneration system (Case1-a, Case1-b) was more effective than the trigeneration system (Case2-a), with an IRR of more than 10% and a PP of less than 10 years. In terms of spillover effects on the local economy, Case 2-a was shown to generate the most spillover effects on the local economy. On the other hand, Case 1-a has the highest IRR (19.9%) including the spillover effect on the local economy. In addition, the regional cash flows for each of the comparison cases were identified to understand the structure of the project. In addition, the study shows the issues and areas for improvement due to data limitations, and provides directions for addressing these issues.
