Electric utilities in the US are grappling with a number of challenges related to electric vehicles, from determining which infrastructure upgrades may be required on their distribution systems to assessing which tariff structures are most effective. As the first wave of EVs hit the US market several years ago, a few select utilities began launching EV tariffs. Northeast Group first published its benchmark and analysis of these EV tariffs and their implications for utilities and EV owners in July 2011. This fifth volume of the benchmark provides an exhaustive look at all of the utilities that have launched EV tariffs to-date. As of June 2015, 28 distribution utilities across the US have launched EV tariffs. Unsurprisingly, many of the utilities are located in California and Michigan. California utilities are at the forefront of several smart grid initiatives, while Michigan utilities are eager to support automobile manufacturers working on transitioning their production lines to EVs. Utilities included in this benchmark are located in the following states:

  • Alabama;
  • Alaska;
  • Arizona;
  • California;
  • Colorado;
  • Georgia;
  • Hawaii;
  • Indiana;
  • Kentucky;
  • Maryland;
  • Michigan;
  • Minnesota;
  • Nevada;
  • Texas; and
  • Virginia.

Key questions answered in this study:


  • Which utilities have launched EV tariffs and what tariff structures have they used?
  • How do EV tariffs compare with the eGallon determined by the DOE?
  • How have utilities structured their electric vehicle TOU rates and what is the average peak to off-peak discount?
  • What issues help determine whether to use single or second meters for EV pricing?
