Amply Power Inc. has calculated how much it costs per dollar to charge an electric vehicle, finding the top 25 U.S. cities could save more than a third by switching to electric buses and fleets from diesel fuel or gasoline.
Amply used publicly compiled data from sources including the U.S. Department of Transportation and AAA, to develop a rating. Amply says it is an apples-to-apples comparison between traditional fuels and gasoline or diesel.
“The cost savings for commercial electrification are real,” said Carla Peterman, former commissioner of the California Public Utilities Commission. “Until now, electrification has lacked a standard to showcase this economic value.”
An Amply white paper showed fleets saved an average 37 percent compared with tradional fuels by electrifying their buses and light-duty vehicles. Fleets that charged during off-peak hours could save as much as 60 percent, the paper says.
An online map offers current electric-to-gasoline price data by city.
Nineteen of the 25 cities could spend less by using electricity instead of diesel or gasoline. Portland, Ore., leads with 82 percent savings by making the switch, followed by Tampa, Fla., at 79 percent, and Seattle at 78 percent.
The metric allows accelerated transition to electric fleets, said Peterman, an Amply adviser.
VEHICLE COST NOT INCLUDED
The study does not account for the cost of buying electric vehicles. They typically cost more than cars, trucks and buses powered by internal combustion engines.
“We partner with OEMs or truck-leasing providers for the whole package,” said Vic Shao, chief executive of Amply.
Shao’s forecasting method looks at regional electric rates and demand charges. It also considers fleet-charging strategies and vehicle classes. Amply uses a dollar range because of the complexity of electricity rate structures and vehicle fleet requirements.
“Savings from electric vehicles can be torpedoed if a fleet is charging at peak rate or charging activities trigger demand charges,” said Simon Lonsdale, Amply head of sales and strategy.
