This study was focused on decreasing the dependency of the country’s energy source from fossil fuels to wind and solar power. This was a research effort to study the possibilities of inclusion of UPSs as energy storage for utility-scale electricity systems. To this end, this research effort looks into making existing UPSs more efficient through better charging and discharging models, linking charging and discharging of a myriad number of UPSs with available renewable generation and to develop an initial cost-benefit analysis of such massive small-scale storage for utilities. Additionally, the study looked into the integration of rooftop solar with traditional batteries for power supplement for the grid during evening hours. Finally, newer highly efficient battery technologies such as Tesla Power Wall and glass batteries for usage as rental energy space for the grid were also studied.
