EPRI – The Value of Transportation Electrification
In this collaborative study, EPRI analyzed and captured the findings of current initiatives that have been undertaken to examine the value of transportation electrification by other organizations as well as individual utilities. The transportation electrification model was applied to three sets of utility data in order to examine specific PEV impacts on their electric power systems. This model specifically simulates utility investments in the charging infrastructure as well as transmission and distribution (T&D) and generation equipment needed to support new charging loads. It also simulates vehicle operation in terms of avoided gasoline use and use of electrical energy over time. Cost-benefit outputs of the model are examined in terms of two performance tests:
The Total Resource Cost (TRC) test measures the net costs of a demandside management program, including both the participant and utility costs. TRC cost components took into account the following: State Tax Credits, Federal Tax Credits, Gasoline Cost, Carbon from Gasoline, Incremental Vehicle Cost, Charger Costs, T&D Cost, Capacity Cost, Energy Cost, Renewable Portfolio Standard (RPS) Cost, Carbon from Electricity, Program Costs, and the Net TRC Benefit.
The Ratepayer Impact Measure (RIM) test measures what happens to customer bills or rates due to changes in utility revenues and program operating costs. RIM cost components took into account the following: Utility Bills, T&D Cost, Capacity Cost, Energy Cost, RPS Cost, Carbon from Electricity, Rate-Based (RB) Charger Cost, Program Costs, and the Net RIM Benefit.
