In Maisí 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.

Since 1984, the Universidad de Oriente and the Centro de Investigaciones Solar (CIES)
have been carrying out wind speed measurements in the municipality of Maisí, 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; García et al., 2016a, 2016b).The
wind map subsequently developed by the Institute of Meteorology of Cuba (Roque-
Rodríguez et al. (Roque-Rodríguez 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
