We employed a bottom-up modeling framework to examine set of scenarios generate insights on the techno-economic and environmental implications increasing levels electric vehicle (EV) penetration using Nigeria as case study. Results indicate that, despite having natural gas-dominated electricity system, deployment EVs can support decarbonization transportation power sectors but at relatively high cost. The cost would need drop by ∼40% become cost-competitive. However, if variable renewable energy sources deliver requirement with bidirectional vehicle-to-grid (V2G) charging strategy, then decline only ∼30%.

Paratransit, in particular the minibus taxi, is mainstay of public transport sub-Saharan Africa. These vehicles are often second-hand, ageing, fuel inefficient, and expensive to operate - issues that electrification can ameliorate. However, modeling planning large-scale transitions electric paratransit require reliable estimates vehicle energy consumption. This paper provides such by applying a kinetic model per-second GPS data gathered on taxis. Data include 62 trips across three routes with different driving conditions near Stellenbosch, South We find range consumption from 0.29 0.51 kWh/km (mean = 0.39 kWh/km). Past literature relied per-minute data, which we show leads inaccurate estimates. recommend new values for operations grid impact, discuss how future work utilize our analysis advance transition
