Regional Analysis of Potential Impacts of Electric and Hybrid Vehicles on Electric Utilities

This paper analyzes the impact of electric and hybrid vehicle (EHV) charging requirements on electric utilities. The impact for the five EHV scenarios examined generally is small, with total EHV electricity consumption in the HIGH scenarios representing ∿3% of projected U.S. electricity demand in 2000. However, in several areas, EHV electricity consumption in the HIGH scenarios represents a sizable fraction of electricity demand in 2000 and would have to be included in utility planning. Based on 1979 fuel prices, the total marginal cost of electicity (excluding taxes) for off-peak EHV charging ranges from $0.017/kWh (Federal Regions I and X) to $0.051/kWh (Federal Region II).
