In a new white paper, the International Council on Clean Transportation (ICCT) has quantified the gap in charging infrastructure across the 100 most populous US metropolitan areas in the US to power more than 3 million expected electric vehicles by 2025.
Broadly, the team found that of the 100 areas, 88 had less than half of the total needed charging infrastructure in place, based on their expected electric vehicle growth.
The authors said that their analysis led to three high-level conclusions:
Much more charging infrastructure is needed to sustain the transition to electric vehicles. Across major US markets through 2017, about one-fourth of the workplace and public chargers needed by 2025 are in place. Charging infrastructure deployment will have to grow at about 20% per year to meet the 2025 targets identified in this report. The largest charging gaps are in markets where electric vehicle uptake will grow most rapidly, including in many California cities, Boston, New York, Portland, Denver, and Washington, D.C.
Planned infrastructure deployment activities are promising, but uneven. There are many government and industry developments underway to deploy the necessary charging infrastructure, and electric utilities are especially positioned to support this infrastructure deployment. In California and other zero-emission vehicle markets, announced measures and planned installations are slated to fill the charging gaps, but such utility and government efforts are largely absent in much of the country. Cities, states, automakers, and utilities with electric vehicle growth ambitions can learn from these leading markets to fill the charging gaps.
Increased charger utilization brings infrastructure investment opportunities. Across US markets where the most charging is needed by 2025, automaker commitments to deploy electric vehicles and the zero-emission vehicle regulation virtually assure increasing electric vehicle uptake. In addition, market expansion, economies of scale, and improved charging technologies will promote higher utilization of chargers. The number of electric vehicles supported by each charger is anticipated to increase by 35% for public Level 2 and 65% for fast chargers by 2025. . . .
