Frequently Asked Questions
How do I know if a TOU plan is right for me?
TOU plans benefit households with high peak consumption and good shift potential - primarily those with EVs, flexible water heating, or large laundry loads. Use this tool with your actual peak share to find out.
What are typical peak and off-peak hours?
Peak hours typically run weekday afternoons from 4 to 9 PM in summer. Off-peak is usually overnight (9 PM to 6 AM) and all day weekends. Check your utility's specific schedule.
What is a shoulder rate?
Shoulder is a mid-price rate between peak and off-peak, used during transitional hours. Not all TOU plans include a shoulder tier - some are just two-part peak/off-peak.
Can battery storage automate the shift?
Yes. A home battery charges at off-peak rates overnight and discharges during peak hours, automatically capturing the rate spread without requiring behavior changes.
