ICE vehicles. On the global market there already exist Solar Powered EV infrastructure as well as Hydrogen
Based charging stations.

The following international studies are also considered in the research:
A Feasibility Assessment of a Solar-Powered Charging Station for Electric Vehicles in North Central region
of Bulgaria from the University of Ruse, Bulgaria. The results of the study conclude that the investment was
profitable and economically sound. However, only a solar potential and financial assessment was done. (Liliya
Mihaylova Ilieva, Simeon Penchev Iliev, 2016).

A Feasibility analysis of a solar-assisted electric vehicle charging station model considering differential pricing
from the Department of Electronics and Communication, JIIT, Noida, Uttar Pradesh India. The study utilized
existing land infrastructure of fuel-based stations for a 100kW PV array which was found to be economically
profitable and recover startup cost within 2.5 years (Nityanshi, Tanmay, Mathur, Vinay Anand Tikkiwal, Kaushal
Nigam 2020). The assessment utilized solar potential together with Hybrid Optimization Model for Electric
Renewables (HOMER) software with predetermined parameters and estimates for financial feasibility.

The Design of a Wind-Solar Hybrid Power Generation System in Sri Lanka thesis study was done for the
KTH School of Industrial Engineering and Management. HOMER modelling software was used to study the
physical behavior and life cycle cost. The design amalgamated the best combination of PV and Wind modules
for economic viability in a grid tied system and concluded a simple payback period of 3.4 years. (Geetha
Udayakanthi M.V.P 2015, 58). The study only considered RE potential and financial assessment.

The Feasibility Study of a Solar-Powered Electric Vehicle Charging Station Model for Shenzhen City, China. The
study utilized HOMER software and concluded the model was acceptable from an economic point of view and
also had a high potential for reduction in pollutant emissions. The study also suggested that carbon pricing
promotes RE use once the price is above USD$20/ton (Bin Ye, Jingjing Jiang, Lixin Miao, Peng Yang, Ji Li and
Bo Shen, 2015, 13280). The study considered financial feasibility and effect of varying interest rates together
with the economic impact of carbon pricing.

This study produced new optimized models that can be adopted for simulating the integration of RE
infrastructure for EV use to any location across Trinidad and Tobago and the region. Most of the previous
studies and analysis conducted in Trinidad and Tobago utilized fixed kWh residential rates in reference to
the grid cost of electrical energy required . This feasibility study instead also looked at the relevant electrical
tariffs and made deductions to accurately reflect the electrical cost involved. To further improve on previous
work and have a precise off grid analysis the study included additionally an Environmental Impact and Risk
Assessment and a Grid Impact Assessment.

Trinidad and Tobago has five (5)
commercial Electric Vehicle (EV) charging
stations and Carbon Dioxide (CO2)
emissions in the transport sector are on
an upward trend. “Range Anxiety” is a fear
developed by customers for running out
of power on a journey and not being able
to find a charging point. Range anxiety
coupled with increase in generation sector
emissions and inadequate electrical
generation capacity for grid charging
stations is highly possible
