Installing Chargers, Charging Stations & Refueling Stations

Here are helpful resources and guidelines for the installation of chargers at home and at multi-unit dwellings, as well as charging stations at workplaces and other locations and destinations.  You'll also find information about Eversource's EV rate program, the availability of hydrogen refueling stations in Connecticut, and any incentives available for home chargers and charging infrastructure, if any.

Level 1 charging:  EVs typically come with a Level 1 EV charger that doesn't require any special installation. Simply plug the Level 1 EV charger into a standard household 120-volt outlet to begin the charging process! It involves no additional installation costs and can be set up without professional assistance. On the downside, Level 1 EV charging is the lowest voltage and slowest form of EV charging.

Level 2 charging:  For a faster charging time, opt to upgrade to a Level 2 EV charger, which uses 240 volts of electricity. A Level 2 EV charger requires a special installation procedure that may be best handled by an electrical contractor. (Appliances such as an electric dryer or an oven also use 240 volts!)

The Office of Energy Efficiency & Renewable Energy (EERE) of the US Department of Energy provides helpful information for installing a Level 2 EV charger at home. In particular, EERE recommends that you consult and understand the EV manufacturer's guidance and information about the required charging equipment before purchasing the equipment and engaging electric services for the installation. Prior to installation of any charger or modification of your electrical system, EERE advises that you check with your electric company and a trusted electrician, and obtain cost estimates.

EERE's Charging at Home

If you're an owner of a multi-unit dwelling, and are considering an EV charging station for your tenants' use, EERE and Transportation and Climate Initiative (TCI) provide best practices and other resources for your consideration.

According to the U.S. Department of Energy (DOE), people with access to EV chargers at their workplace are six times more likely to purchase an EV. If your company or its employees are considering installing an EV station, both EVConnecticut and TCI provide practical walkthroughs of steps to take for greater success.

At this time, the State of Connecticut does not offer any incentives for EV chargers or charging stations.

If you're a customer of Groton Utilities or Bozrah Light & Power, Groton Utilities offers a $600 rebate toward an approved Level 2 charging station.  Visit Groton Utilities' Electric Vehicle Rebate Program webpage for more details.

Maps are available that identify the existing and planned hydrogen refueling stations in Connecticut and the northeast U.S.
