El presente estudio evaluó la factibilidad técnica y financiera de la especie dentro de condiciones de una plantación de alta densidad; para lo cual se estableció una plantación piloto de 12 hectáreas en Guanacaste, Costa Rica y se manejó con un ciclo productivo de 159 días y limitando su manejo a aplicaciones de tres dosis nutricionales de nitrógeno (85, 131 y 17 kg ha-1); posterior de la cosecha se evaluó la biomasa acumulada, el poder calórico y su viabilidad financiera para ser implementada en una caldera de 2 MW de potencia. Los resultados mostraron una cosecha de: 85 a 110 ton ha-1 de biomasa seca, encontrado los mayores valores en el tratamiento que usó mayor dosis de nitrógeno; también, se encontró que la biomasa seca de la especie es apenas del 24 % de la biomasa total, pero con un poder calórico superior a 3 800 cal g-1, que incidió en que el potencial eléctrico real fuera de 1,33 MWh ton-1 (considerando una caldera con una eficiencia del 30 %) suficiente para que una plantación de 200 ha con dos ciclos de cosecha al año y a una distancia inferior de 45 km de la planta pueda generar electricidad con una rentabilidad financieramente aceptable; el análisis financiero evidenció este tipo proyecto es viable siempre y cuando la producción de biomasa no sea menor a 120 ton ha-1, el costo del kilowatt hora sea inferior 0,10 USD y las plantaciones no estén a más de 45 km de la planta.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract Pennisetum purpureum (Schumach) is a fast-growing herbaceous species with calorimetric properties which gives it ideal conditions to be implemented in biomass projects of electricity generation for Costa Rica. The present study assessed the technical and financial feasibility of the species within conditions of a high-density plantation; for which a pilot plantation of 12 hectares was established in Guanacaste, Costa Rica and was managed with a production cycle of 159 days, limiting its running to applications of three nutritional doses of nitrogen (85, 131 and 17 kg ha-1); after harvesting, the accumulated biomass, the caloric power, and its financial viability were evaluated to be implemented in a boiler of 2 MW of power. The results showed a harvest of: 85 to 110 ton ha-1 of dry biomass and found the highest values in the treatment that used higher doses of nitrogen; it was also found that the dry biomass of the species is just 24 % of the total biomass, but with a caloric power greater than 3800 cal g-1, which showed the actual electrical potential to be 1.33 MWh ton-1 (considering a boiler with an efficiency of 30 %), enough for a plantation of 200 ha with two harvest cycles per year and at a distance of less than 45 km from the plant to generate electricity with a financially acceptable profitability; the financial analysis showed this type of project is viable as long as the production of biomass is not less than 120 ton ha-1, the cost of the kilowatt time is lower 0.10 USD and the plantations are not more than 45 km away from the plant.]]></p></abstract>
