Abstract. Power distribution inefficiencies and heavy reliance on diesel generators remain key challenges in Palawan. As one of the major coconut producers in the Philippines, Palawan’s coconut residues present significant biomass energy potential to address energy issues while promoting clean energy production. This study evaluates the theoretical and available energy potential of coconut residues in Palawan and identifies biomass collection points (BCPs) based on their biomass collection capacity within a 0.7-km radius and proximity to the road network. These points are used as supply sources, with candidate sites as demand points, and the road network is incorporated to optimally locate biomass conversion facilities using Geographic Information System (GIS) and spatial analysis. Results indicate an estimated theoretical potential of 15465.919 metric tons and an available potential of 85.173 MJ/ha, sufficient to supply one biomass energy facility with an approximate capacity of 1.5 MW. Twelve BCPs were identified in Southern Palawan: two in Sofronio Espanola, three in Rizal and Brooke’s Point, and four in Quezon. Additionally, eight BCPs were identified in Cuyo Island: three in Cuyo and five in Magsaysay. There are 96 candidate sites determined as potential locations for biomass conversion facilities. The optimal site for a biomass conversion facility was identified in Quezon, Palawan. In conclusion, this research effectively employed GIS and the BCP framework to locate biomass collection points and strategically determine the optimal site for a biomass conversion facility.
