The paper presents information on the cultivation of prairie cordgrass as a dedicated energy crop. The basic agro-technical treatments for this plant are also presented. Moreover, the optimum parameters of compaction to the form of pellets for prairie cordgrass, i.e. optimal chaff length and moisture content of the material, obtained as a result of the study, are indicated. The study showed that optimum moisture content of the raw material for the pelleting process should be in the range of 12-14%. It is also important to prepare prairie cordgrass in terms of particle size. For the production of pellets form prairie cordgrass, the optimum chaff length should be in the range of 3-8 mm. With the optimal parameters for raw material, the pellet obtained has the correct shape and form while maintaining stability during storage and warehousing. The study showed that for pellet made from prairie cordgrass at moisture content of 10.09% the heat of combustion was 17.02 MJ kg^-1 and the calorific value was 15.62 MJ kg^-1, and at moisture level of 7.55% the heat of combustion reached the value of 18.31 MJ kg^-1 and the calorific value was 16.93 MJ kg^-1. Analysis of results indicates that when moisture content increases by 2.54% the heat of combustion decreases by 7.07% and the calorific value by 7.76%. The tests showed a low level of ash content for prairie cordgrass compared to that of fossil fuels. At combustion temperature of 600ºC it amounted to 6.02% at moisture content of 10.09%, and to 4.86% when the level of moisture content was 7.55%. Statistical analysis showed that moisture content of material affects the ash content. The obtained result of the calorific value and ash content indicate that this plant is a good renewable source of energy. Moreover, easy forming of pellets with set parameters for raw material makes this plant a valuable fuel in power plants.
