This paper presents the results of the continuity in a research process carried out at the Center for Energy and Environmental Technologies Studies, belonging to “Marta Abreu” Central University of Las Villas, related to obtaining models for the determination of caloric powers and chemical exergy contained in any solid combustible element of biomass origin. The main formulations known in the literature are presented, as well as the results obtained by the authors to represent the lower caloric power and the chemical exergy in terms of elemental composition (C, H, O, N, and S). The formulations obtained correlate with the samples considered between 5% and 15% for the higher caloric power, and between 1,3% and 2,4% for chemical exergy. Based on these correlations, this study provides the relationship between higher caloric power and chemical exergy as a function of the elemental composition of C, H, O, N, and S in the fuel masses that will be used in biomass thermoelectric power stations (TPS) in process of construction in the country
