The global energy matrix is being remodeled, with an increasing share of renewable sources, with biomass being considered the third largest source of energy in the world. The work aims to manufacture 100% jaraguá gr grass/charcoal b ass briquettes and the lend and analyze the in natura residues for the production of electricity in a 66 MW thermoelectric power plant. A mixture of 75% jaraguá grass and 25% charcoal fines was made, obtaining a higher calorific value of 21 023J/g. With a hydraulic press, the sam ples were briquetted at a pressure of 15,000 kg/cm3 for one minute. Through the immediate chemical analysis performed in triplicate, it was observed that the blend had 10.3% of ash content and 42.7% of volatile conten t , resulting in 47% fixed carbon. In th e durability test, a durability of 13% was obtained for the blend and for the jaraguá grass briquette of 93% durability. From the definition of a mathematical model of a thermoelectric power plant and a comparative an alysis between in natura biomass as fue ls, it was proved that the use of blends for thermoelectric generation is viable, as the amount of biomass used is reduced, in addition to supplying the negative effects of seasonality during the year with the use of residues with similar elementary charac teristics.
