Electric vehicle (EV) adoption and charging infrastructure are growing rapidly in Maine. As of January 2023, there were over 12,000 EVs registered in the state, up from just a few thousand in 2018. This growth is being driven by several factors:

  • Improving EV technology and falling battery costs making EVs more affordable. Many new, long-range EVs can travel over 200 miles on a single charge.
  • Increasing awareness and demand from consumers for zero-emission vehicles.
  • Government incentives at both federal and state levels that reduce the upfront cost of purchasing an EV.

To support this rising number of EVs, Maine has seen large expansions in public charging infrastructure over the past few years. In 2015, there were only about 100 public charging stations statewide. Today there are over 600, with many more planned. Most public stations are Level 2 chargers which can provide around 25 miles of range per hour of charging. DC Fast charging stations, which can charge an EV much more rapidly in around 30 minutes, have also increased from just a couple locations to over 25 today.

Maine’s scenic landscapes and coastal regions have also begun attracting EV-driving tourists from all over New England and beyond. This provides an opportunity to continue expanding charging options to support tourism growth. Overall, Maine is on the leading edge of EV adoption in New England, though still significantly behind EV leader California. If current growth trends continue, EVs could make up over 5% of Maine’s vehicles by 2025. But ensuring adequate charging infrastructure remains a key challenge.

Maine faces several key challenges as it looks to increase EV adoption across the state.


The upfront cost of purchasing an electric vehicle remains higher than comparable gas-powered models. The average cost of a new EV is around $55,000, compared to $45,000 for a standard gasoline car. This price differential poses a significant barrier, especially in rural areas where incomes tend to be lower. Various federal and state incentives help offset the cost, but more will need to be done to achieve price parity.


Consumer awareness and understanding of EVs is still relatively low in Maine. Myths persist around limited range, lack of charging options, and higher maintenance costs. Car dealerships have an important role to play in educating potential buyers on the realities and benefits of EV ownership. More marketing and educational campaigns can help spread accurate information to mainstream audiences.

Charging Availability

While Maine’s charging network has expanded considerably, gaps in coverage remain, particularly in rural and remote areas. This causes range anxiety for drivers and reduces EV appeal. Further investment is required to build out charging infrastructure along major highways, in small towns, and even at individual residences. The state needs to incentivize utilities and private companies to fill in the gaps.

Overcoming these barriers will require a concerted effort by policymakers, businesses, utilities, and EV advocates. But doing so will enable Maine to reap the economic, environmental, and energy independence benefits of widespread electric vehicle adoption.
