This thesis investigates the potential for performance enhancement of interconnected minigrids in Nigeria through demand-side flexibility, quantifying the operational and economic implications for project developers and customers. Using empirical consumption data from over 800 customers, the study categorises users by consumption level to identify high-demand households with realistic potential for load shifting. Energy use for each appliance was estimated based on common household appliances and their typical usage durations. This analysis identified which appliance loads could be shifted to different times of day. A Time-of-Use pricing model was implemented to encourage the redistribution of shiftable loads to off-peak hours, aligning consumption with periods of higher solar photovoltaic (PV) availability.
