A $4 million U.S. Department of Energy grant will fund a network of DC fast chargers in three Rocky Mountain states to develop electric highway corridors along the I-15, I-80, I-70 and I-84 in Utah, Wyoming, and Idaho.

The grant will also help develop smart mobility programs to increase electric car-sharing and the use of electric bikes and buses, according to Rocky Mountain Power.

The DC fast chargers will be built every 100 miles along the corridors and AC level 2 chargers in every community in the region. It will also offer incentives to employers to install charging stations; help businesses purchase 200 EVs and more than 13,800 electric rental vehicles; and develop smart mobility programs to use technology, collect data and develop practices to meet long-term transportation plans.

In the next 10 years, the grant would double the region’s number of electrified vehicles to 50,000 cars, which would result in the annual reduction from 251 million pounds of carbon-dioxide emissions and 24.9 million gallons of gasoline, according to Rock Mountain Power.

"Our goal is to have enough charging stations to help electric vehicles go from Disneyland to Yellowstone and everywhere in between," said Cindy Crane, Rocky Mountain Power's president and CEO.

The project partners include the Utah Office of Energy Development, University of Utah, Utah State University, Salt Lake City, Utah Clean Cities Coalition, Breathe Utah, Idaho National Laboratory and others.
