This study examined the impacts of plug-in hybrid electric vehicle (PHEV) charging scenarios in Illinois (IL) in the year 2030. We examined the impact of PHEV market penetration and charging scenarios on the electric utilities and transmission grid, and estimated the potential reductions in petroleum use and greenhouse gas (GHG) emissions due to displacing petroleum with electricity. Two charging scenarios were considered: (1) PHEVs start recharging upon arrival at home at the end of their last daily trip (arrival time charging), and (2) PHEVs recharging during overnight hours when the demand on the grid is the lowest (smart charging, with no needed investment in new capacity). The two charging scenarios produced distinct hourly load profiles, with increased load during the daytime for the arrival time charging scenario. Utility dispatch simulations for these charging scenarios predicted dissimilar marginal generation mixes and GHG emissions for the same PHEV total demand, with more dispatching of coal generation in the smart charging scenario. A well-to-wheel (WTW) analysis showed that PHEV10 and PHEV40 can reduce petroleum use by 46% and 63%, respectively. Depending on the vehicle's electric range and the hourly charging (load) profile, PHEVs in IL can reduce GHG emissions by 16% to 36% compared to conventional gasoline internal combustion engine vehicles (ICEVs).
