An Agent-Based Model (ABM) is developed in Netlogo as a tool for evaluating impacts of subsidies on temporal diffusion of PV microgeneration systems in a rural developing community. ABMs model individual micro entities within a complex system and the rules that govern the interactions between them within the system, to capture the macro-effects of such interactions. The model simulates how introduction of subsidies would influence households’ electrification choices within a given rural developing community over a given period, given various electrification options. Survey-gathered data from Kendu Bay area of rural Western Kenya is used to inform the model. Results show that introduction of capital-based and energy-based subsidies would lead to significant increases in PV installations, which in turn translate into more formations of communal grids (minigrids and microgrids). Observations made from this study can be applied to many similar locations in sub-Saharan Africa. But most importantly, the model could be used by policy-makers in formulating rural electrification policies.
