with BESS is TTD$0.4302/kWh which is lower than the non-subsidized grid rate and comparative to international
rates for systems of the same size. The LCOE is comparable to the current T&TEC commercial electricity rate
in Trinidad and Tobago. If the government were to incorporate tax exemptions for these investments, the
Milford-24 location will have a NPV in excess of TTD27.9M and the IRR-13.71%, MIRR-13.35%, ROI-703.51%
and Profitability Index-8.04. The tax exemptions will make the investment almost twice as financially feasible
even when considering the subsidized rates of electricity.
