This study aimed to analyze the energy potential and wood quality of Tectona grandis Linn F., using different positions along the stem (base, middle, and top) and thinning ages (56 and 92 months). The study material was from the city of São José dos Quatro Marcos, MT, Brazil. Analyses of higher heating value, proximate chemical composition and density were performed. Analysis of variance revealed no differences along the stem for all properties studied. However, there was significant variation at 1% probability density as a function of age, in which the highest averages were from the second thinning (0.584 g.cm-3). The average position between thinning and age were 4,594 kcal.kg-1 for higher heating value; 80.37% for volatile materials; 18.39% for fixed carbon and 0.59% for ash.
