Utility-Provided Special EV Tariff Rates Becoming More Common In US

July 6th, 2015 by  

Special utility company–provided electric vehicle (EV) tariff rates (for home charging) are becoming more and more common in the US, according to a new study from Northeast Group.

Considering that EVs are becoming more and more common throughout the US, the findings aren’t very surprising — after all, if you’re charging your EV every night during off-peak hours, why wouldn’t you want a good deal?


As it stands now — according to the study — there are 28 different utility companies in 15 different states providing EV charging specific rates.

“After several years of trial and error, utilities are beginning to learn what tariff structures work best for EV owners,” stated Ben Gardner, president of Northeast Group. “Several utilities that previously offered EV tariffs on only a pilot basis now offer full EV tariffs. The benefits of large overnight rate discounts for those charging EVs during off-peak hours are becoming clear to both EV owners and utilities.”

While much of this has been self-directed, governments have been involved as well. For instance, in Minnesota, recent legislation has resulted in all large utility companies now being required to offer specific EV charging rates.

“With gasoline cheaper than in years past, EV tariffs will be an increasingly important incentive,” noted Gardner. “Across the 15 states with EV tariffs, the average equivalent ‘price per gallon’ was $0.77. Using standard electricity tariffs, the US Department of Energy calculated that the cost of an ‘eGallon’ in these states was $1.39. The average cost of gasoline in these states was $2.81.”

According to the study, there are, altogether, more than 24 million utility customers throughout the US with access to EV tariffs. Those interested can find the full study here.
