The number of utilities offering EV tariffs has increased from eight a year ago to 22 today, but that still represents just 6% of utilities nationwide, according to a new report from Northeast Group. And though a number of the utilities offering EV tariffs are located where you might expect – in California and Michigan – they actually crisscross the country, from Alaska to Georgia.

 

The report suggests that some utilities are playing a key role in encouraging EV adoption through their incentive and rebate programs. A couple of examples:

·         Progress Energy Carolinas reached full capacity for its EV charger rebate in May 2012

·         Northern Indiana Public Service Co is offering free off-peak charging

But incentives don't work if customers aren't interested in EVs. The report notes that Alaska Electric Light and Power has had EV rates and rebates in place since January 2011, but so far only three customers have signed on.

 

Of the 22 utilities in 11 states that are offering EV tariffs, the report indicates:

·         Most have taken two main forms -- time-of-use (TOU) and flat rate plans

·         They are typically one-half the cost of standard electricity tariffs to recharge an EV
