This research was aimed to identify the areas in the northern region of Thailand that have
potential for utilizing biomass fuels in electricity generation. In order to improve the efficiency of
thermal energy utilization in the areas, the combined heat and power systems (CHP) were proposed for
electricity generation as well as heat utilization in dehydration of agricultural products. The criteria for
identifying the suitable areas involved the availability of biomass, the availability of 22 kV electrical
grids and the electrical power consumption. The possible electrical generating capacities for each local
area were presented in the map regimes presented in this article.
