ABSTRACT
In Maisà municipality, the easternmost municipality of Cuba,
belonging to Guantánamo province, at coordinates 20,270
N and 74,220 W approximately, pre-feasibility studies are
being carried out for a wind farm project in two sites
known as Punta Fraile and Punta Quemado. Two variants
are proposed. The objective of this work was to perform
sensitivity analyses on the profitability of the parameters
susceptible to change, in order to determine the limits
within which they can move without the project becoming
unprofitable. For the studies, a program was designed for
pure and hybrid renewable sources; it has a module for the
estimation of the capital cost based on the relevant
parameters of the project, which guarantees equal
conditions in the analysis of variants. The economic-
financial evaluation is carried out using four fundamental
criteria that complement each other. The results are given
in the form of a comparative table of variants and influential
sensitivity parameters.

RESUMEN
En el municipio MaisÃ, el más oriental de Cuba,
perteneciente a la provincia Guantánamo, en las
coordenadas 20,270 N y-74,220 O aproximados, se
realizan los estudios de pre factibilidad del proyecto de un
parque eólico en dos emplazamientos conocidos por Punta
Fraile y Punta Quemado. Se proponen dos variantes. El
objetivo de este trabajo fue realizar los análisis de
sensibilidad sobre la rentabilidad de los parámetros
susceptibles de variar, con la finalidad de determinar los
lÃmites dentro de los cuales se pueden mover sin que el
proyecto deje de ser rentable. Para los estudios fue
diseñado un programa para fuentes renovables puras e
hÃbridas; dispone de un módulo para la estimación del
costo capital a partir de los parámetros relevantes del
proyecto que garantiza igualdad de condiciones en el
análisis de variantes. La evaluación económico - financiera
se realiza mediante cuatro criterios fundamentales que se
complementan. Los resultados se dan en forma de tabla
comparativa de las variantes y parámetros influyentes de la
sensibilidad.

INTRODUCTION
Since 1984, the Universidad de Oriente and the Centro de Investigaciones Solar (CIES)
have been carrying out wind speed measurements in the municipality of MaisÃ, which
together with the data base accumulated by the meteorological station at the lighthouse
of that strategic point for navigation, made it possible to analyze the seasonal and
monthly behavior of the region.(Burton et al., 2011; GarcÃa et al., 2016a, 2016b).The
wind map subsequently developed by the Institute of Meteorology of Cuba (Roque-
RodrÃguez et al. (Roque-RodrÃguez et al., 2019)allowed corroborating the hypothesis
that there was a good wind potential in the area. The mean annual velocity calculated
with the monthly average values and extrapolated to 50 m altitude, as well as the
