Our electric vehicle savings calculator has a new look and some new features. Now you can input the estimated number of miles you drive each day and select from hundreds of makes and models of vehicles to compare fuel costs.    

The calculator lets the user change the local fuel price per gallon as well as estimated miles per gallon for gas-powered vehicles from the factory default miles-per-gallon setting. You can also change the estimated miles per kWh for electric vehicles and the price-per-kilowatt based on San Isabel Electric’s on- and off-peak rates.  

San Isabel Electric also offers a new way to explore what electric vehicles are currently available. Simply select the features that are most important to you and our new tool will help you find the electric vehicle that will best meet your needs. You can search by number of seats, miles per charge (range), price, along with manufacturer, vehicle type (compact, hatchback, minivan, pickup, etc.), all-electric or plug-in hybrid, and year.

Most utilities, including San Isabel Electric offer a special on-peak off-peak rate to make charging electric vehicles more affordable. These rates are known as time-of-day or time-of-use rates. San Isabel Electric’s time of day rate gives qualifying members nearly half-price electricity during off-peak times, 14 hours a day in the winter, and 8-hours a day in the summer.   

The cost to fully charge an electric vehicle at home is much less than the cost to fill up with gas. It would cost about $11 to fully charge a Tesla Model 3 during off-peak hours for a San Isabel Electric member-owner. The rear-wheel drive model 3 has a range of about 272 miles. Compared to a gas-fueled vehicle, the cost per equivalent miles is significantly cheaper for electric-fueled vehicles. 

Member-owners signed up for San Isabel Electric’s time-of-day off-peak pay $0.076 per kWh for the first 1,000 kWh. After the first 1,000 kWh the rate goes down to just $0.062 per kWh. There is an additional $10/month access charge, year-round, for member-owners on time-of-day rates.
