Connecticut Electric Vehicle (EV) Planning Resources



Electric Vehicle Planning Resources


The Connecticut Department of Transportation (DOT) is committed to working with others to expand electric vehicle adoption and help drivers realize the benefits of driving zero emission. We have compiled resources from across platforms to help researchers, charging station installers, municipalities, and other stakeholders in advancing electric vehicles in the State of Connecticut. 

General Resources:

U.S. Department of Energy’s Alternative Fueling Station Locator: Connecticut has over 400 public EV charging stations and this interactive database shows EV charging station data (Level 2 and DCFC) throughout the country.

The Joint Office of Energy and Transportation: The Joint Office of Energy and Transportation was created through the Bipartisan Infrastructure Law (BIL) to facilitate collaboration between the U.S. Department of Energy and the U.S. Department of Transportation. The Joint Office provides unifying guidance, technical assistance, and analysis to support federal programs.

EVConnecticut: This is a DEEP run website that is focused on educating the public about electric vehicles. Consumers, businesses, and government entities can find information about State EV incentives, tax credits, the difference between types of EV vehicles and much more.

Drive Change. Drive Electric: This is a public-private partnership between automakers and US Northeast states to advance consumer awareness, understanding, consideration and adoption of electric cars. The website has tools to help drivers explore if an EV is right for them and addresses the benefits and challenges that come from being an EV owner.   

U.S. Environmental Protection Agency’s Green Vehicle Guide: This federally run website provides users tools and resources about green vehicles and how to spend less on gas by driving more efficiently.

Connecticut Focused EV Data Analysis Tools

EValuateCT Dashboard: Connecticut has seen tremendous growth in electric car registrations since the launch of the Connecticut Hydrogen and Electric Automobile Purchase Rebate (CHEAPR) in 2015. Using vehicle registration data from the Connecticut Department of Motor Vehicles (DMV), DEEP and DOT have worked with Atlas Public Policy to develop the EValuateCT dashboard.

The EvaluateCT dashboard is a tool that compiles statistics on the electric car market, including where registrations are, what makes and models are most popular, and more. Users can drill down for more or details, and the maps and charts are interactive. DMV data is typically updated biannually (January and July).

EValuateCT also incorporates additional data from U.S. Department of Energy, U.S. Census Bureau, and other sources to provide information about demographics of communities with high electric car ownership, where charging station are located, and more.

The information below is a small snapshot of what is available in the EValuateCT dashboard. To access the full EValuateCT dashboard, click on the "Launch EValuteCT" area on the image below.

Planning for EV Charging Installation

Connecticut Host Capacity Maps: These maps detail the existing grid conditions and operations that the utilities infrastructure can accommodate, with limited system upgrades, while still reliably and safely delivering electricity. The information found on these maps details the hosting capacity by circuit and direct clicks on circuits will also bring up more detail about the circuit, its remaining capacity and related substation.

Please review the maps and work with your local utility to submit an interconnection application. The utilities will work with you to complete an impact study to determine the scope of upgrades needed to install EV charging at your facility.

Eversource EV Host Capacity Map for Connecticut 

United Illuminating EV Load Capacity Map

EV Planning Resources: Equitable Planning: This website offers interactive tools, maps, software, and datasets that the U.S. Department of Transportation has compiled to aid in EV infrastructure planning and implementation.

Regional EV Charging Infrastructure Location Identification Toolkit (ILIT): The ILIT calculator was created by M.J. Bradley & Associates to assess the suitability of potential DC fast charging sites by allowing the user to identify and rank candidate locations based on user-supplied priorities.

EV Charging Financial Analysis Tool: The EV Charging Financial Analysis Tool is a Microsoft Excel-based tool that performs a detailed financial analysis of owning and operating EV charging stations and creates a summary dashboard for users.

Procurement of Equipment: Public purchasing entities (municipalities, state facilities, school districts, etc.) can purchase EV charging equipment off the State contract by using the Electric Vehicle Supply Equipment (EVSE) Services, Infrastructure and Planning contract (#21PSX0027) found on the CTsource Contract Board.   

Fleet Resources

Dashboard for Rapid Vehicle Electrification (DRVE) Tool: The DRVE tool is a Microsoft Excel-based tool that helps users compare their existing conventional fleet vehicles with EV alternatives. Outputs include cost of ownership and emissions based on the regional electric grid. Users can customize the market, charging, and procurement settings to explore different scenarios.

Climate Mayors Electric Vehicle Purchasing Collaborative: Purchase or lease electric vehicles and charging stations using competitively bid contracts. Open to all U.S. cities, counties, state governments and public universities. The Collaborative also provides training, best practices, educational resources, and analysis support that creates a one-stop shop to support EV transitions for fleet vehicles.

Local Government Playbook: How Counties, Cities, and Town Can Support EV Infrastructure and Leverage Federal Investments: This 2022 report contains recommendations for how counties, cities, and towns can support EV infrastructure and leverage federal investments. It also provides actions and strategies that local governments can enact now and, in the future, including best practices, policy approaches and lessons from previous charging deployments.
