Key Highlights

• Analysis of fast-charging needs provides blueprint to ready the grid along major highways
• Mapping long-term charging demand will avoid duplicate infrastructure investments
• Interconnecting highway charging sites to high-capacity lines can meet demand

Electric vehicle (EV) charging needs along Massachusetts and New York highways will require interconnection to high-capacity transmission lines in the next decade, finds a first-in-the-nation study released today. The Electric Highways Study provides a blueprint for the strategic buildout of fast-charging sites along highway corridors to meet an upcoming surge in demand from the electrification of passenger vehicles and commercial trucks.

EV adoption is expected to accelerate nationwide due to market forces and federal policy changes, including the Infrastructure Investment and Jobs Act of 2021 and the Inflation Reduction Act of 2022. At the state level, New York's adoption of the Advanced Clean Cars II regulation and Massachusetts' passage of "An Act Driving Clean Energy and Offshore Wind" will ban the sale of gas-only passenger vehicles by 2035.

National Grid and leading transportation analytics organizations CALSTART, RMI, Geotab, and Stable Auto, conducted the analysis to provide new insight into the future of EV highway charging in New York and Massachusetts and to better understand the impact of this transition on the grid.

The Electric Highways Study can help utilities and policymakers make smarter decisions about electric grid interconnections and infrastructure, avoiding repeated upgrades and ensuring grid readiness does not hinder the clean energy transition.

"This kind of holistic, long-term infrastructure planning will be critical to delivering a clean energy transition as efficiently as possible," said Brian Gemmell, Chief Operating Officer NY Electric, National Grid. "We have a responsibility to make smart investments that get it right the first time and to make sure the electricity is there when drivers need it. This study will help us do that."

EV Fast-Charging Site Demand

The study examined current traffic patterns and expected charger use to forecast charging demand at 71 highway sites across New York and Massachusetts. The analysis included relevant electric vehicle sales goals and mandates in National Grid's home states — considering scenarios where all light-duty vehicle sales are electric by 2035 and all medium-and heavy-duty vehicle (MHDV) sales are electric by 2045.

According to the findings, in 10 years more than a quarter of sites studied will require the same amount of power as an outdoor sports stadium to meet charging demand, with some requiring the same power as a small town within the next two decades.

Existing transmission lines, which often mirror highway routes, provide a ready-made solution if highway charging sites can "plug-in" to the high-voltage transmission grid. Strategically future-proofing high-traffic sites will allow states to accelerate cost-effective charging deployment.

"As EV technology matures to suit more duty cycles, electrifying locations along major highways will be critical to ensuring a zero-emission transportation future, from passenger cars to long-haul trucks," said Ben Mandel, Senior Director for the Northeast Region, CALSTART. "Our study with National Grid and partners provides the clear insights policymakers will need to support an equitable and cost-efficient buildout of fast charging at the scale needed to meet the EV adoption targets in place for New York and Massachusetts."

"The Inflation Reduction Act will close the cost gap between diesel and electric trucks and create a surge of demand from buyers and investment from suppliers in the near future," said Dave Mullaney, Principal - Carbon Free Transportation, RMI. "The biggest challenge to deploying those electric trucks will be finding the power to charge them. This study takes the first steps to overcoming that barrier and serves as a roadmap for the rest of the country to follow."

"Sufficient highway charging infrastructure for light-duty vehicles is paramount to mass EV adoption in the US," says Stable co-founder and CEO Rohan Puri. "Stable's predictive models use millions of geospatial data points mapped with true utilization rates from thousands of chargers operating today to help understand today's demand and how it will grow. Forecasting future power needs informs planning and allows for the strategic deployment of charging infrastructure while maintaining a strong electric grid."

"Sustainability is core to our purpose at Geotab, and data intelligence is key to the transformative decision making needed for the future of our planet. We are thrilled to bring Geotab ITS origin and destination data insights to support National Grid, CALSTART, and RMI, and help inform the future of highway fast-charging in New York and Massachusetts," said Nate Veeh, Sr. Business Development Manager, ITS at Geotab. "Geotab ITS medium- and heavy-duty truck data was used at an aggregate level to help the teams better understand travel and stopping behaviors in order to pinpoint optimal areas for future charging infrastructure."
