WIND POTENTIAL
Trinidad and Tobago has a Class 2 wind potential capable of generating less than 260W/m2 in more than
90% of all land locations (IRENA, 2021). The information was validated and found to be consistent with the
Global Wind Atlas 3.0 model. There are seven classes of wind potential as indicated in the table. The National
Renewable Energy laboratory (NREL) would have published the classification system based on a Rayleigh
Probability Distribution of mean power densities.

NREL land-based Wind Power Classification based on Rayleigh Probability Distribution

According to the land-based mean power density Trinidad and Tobago falls in Class 2 which indicates a
marginal potential for using wind energy for renewable energy projects. Marginal potential projects will
require larger wind turbines to capture energy and will require larger areas for installation. Marginal potential
justifies the already researched evidence that wind energy will not be viable as a potential RE source for design
of the EV charging stations.

RESOURCE ASSESSMENT
The calculated annual average Solar PV potential for installation at the Milford-24 fuel station is approximately
1984.72kWh/m2 per year for fixed tilt panels installed at 11.15° at azimuth of 180°. A Sun Path Chart was used
to analyze the effective time of solar irradiance and shading at the location. UO SRML was used to generate
the Sun Path Chart for the Milford-24 location. The annual average Solar PV potential was also simulated in
GSA2.6 and was found to be 1906.3 kWh/m2.
