We know customers with plug-in electric vehicles (PEV) have unique energy needs. We currently don't offer an electric rate specific to PEV owners. Our Three-Tier Time-of-Use rate option can help you reduce the cost of charging your vehicle.
Three-Tier Time-of-Use can save you money when you shift the greatest share of your electricity use, like charging your PEV, to the Off-Peak savings hours. These hours are times of the day and night when electric demand is typically low. Those hours are in effect over half of the time, including all weekends and holidays. So a simple change in when you charge your PEV, and use electricity in general, can result in substantial savings.
For those times you can't completely shift to Off-Peak hours, using electricity during the Mid-Peak hours would be the next best option.
PEV owners can expect to see an increase in their electric bill. The increase will vary depending on the amount the vehicle is driven and how the vehicle is charged. However, electricity is a less expensive transportation fuel then gasoline and diesel so owners are still saving.
Below is a graph showing monthly gasoline prices since 1970 vs. pricing of electricity for the same timeframe in a dollars per gallon equivalent.
* Based on a plug-in electric vehicle with an efficiency of 3.4 miles per kWh (like the Nissan Leaf) and an internal combustion engine vehicle with a 30 mpg rating.
