[En anglais seulement] This study explores the economic benefits of a Vehicle-to-Home (V2H) system for residential consumers. Through a model minimizing the daily total cost of electricity by arbitraging from the price differential throughout the day, with a V2H system, we are able to analyze its value. Residential time-of-use tariffs from four different jurisdictions (Quebec, Vermont, Michigan and California) are used, under three different usage scenarios (Car away from 8am-6pm, Part-time at home and Full-time at home). Residential load profiles without and with electrical heating are analyzed. We find that, for the most common case in the United States where heating is not electricity-based, annual savings can be substantial in some cities. Savings are however highly dependent on the prevailing time-of-use (TOU) tariff and price differential between peak and off-peak periods. For the city of Burlington in Vermont, with one of most aggressive TOU tariffs, annual gains range from US$157 to US$379. For Detroit in Michigan, annual economic benefits go from US$24 to US$190. For San Diego in California, annual gains are high and go from US$620 to US$1,153 when choosing the appropriate tariff. For Santa Rosa in California, savings can be null or go up to US$100, depending on the car availability and the tariff applying. For Quebec, the consumer’s bill reduction ranges from CAD$230 to CAD$475, when households use electric heating, as it is common.
