Abstract: . . .  placing the STWH in strategic sectors of the island, for example, the metropolitan area. Economic analysis including the value of money throughout time could be done. The results were as expected, so this alternative should be considered for all the benefits mentioned throughout this work. 142 REFERENCES [1] H. Salehfar, Senior Member, IEEE A.

Upcoming studies could also calculate the power loss reduction and generation displacement including distribution voltages as 13.2kV, 4.16kV and so on. Optimization of the model could be done by placing the STWH in strategic sectors of the island, for example, the metropolitan area. Economic analysis including the value of money . . .

Puerto Rico’s abundant solar resource could be exploited via Solar Thermal Water Heating to achieve all of these potential benefits. 141 By reducing the flows on the system the risk of thermal overheating is reduced, thus causing an overall improvement in the system’s reliability. The improvement on the system’s reliability could be included in future studies.
