Do Xcel Energy (CO) time-of-use hours change during holidays or seasons?
Yes. Peak hours and rate periods can vary by season (typically summer and winter halves) and special holidays. While some schedules like E-ELEC keep stable hours year-round, others introduce super off-peak windows or adjust peak times. Check each rate plan card above for specific seasonal boundaries.
-
What is the best time to charge an EV under Xcel Energy (CO)'s plans?
For customers on EV-specific plans like P-EV, S-EV, the most cost-effective time to charge is during super off-peak or off-peak hours. Charging during these designated windows significantly reduces electricity costs and minimizes demand on the grid.
