We observe that over the last 11 years, EV drivers across the United States have contributed approximately $3.12 billion more than their associated costs, driving rates down for all customers.
When we also include utility expenditures for EV programs, EV owners have contributed approximately $2.44 billion more in revenues than in costs.
we assume the majority of EVs are charged at home and mostly in the early evening at the end of the workday
A key reason why revenues from EVs outweigh the costs is that EV customers — particularly those on TOU rates — tend to charge during off-peak hours
By charging during off-peak hours, EVs impose minimal additional costs on the grid and help to utilize resources more efficiently
report published in 2019 by Lawrence Berkeley National Laboratory, PG&E, and the Natural Resources Defense Council shows that shifting EV charging to off-peak hours could allow the grid to accommodate all homes having EVs without upgrading most parts of the distribution system
