Understanding Peak Hours

SDGE uses Time-of-Use (TOU) rates that vary based on when you use electricity. Understanding these periods can help you save significantly on your energy bills.

On-Peak

4 PM - 9 PM

Highest energy demand and most expensive rates

Smart Usage Tips:

• Avoid running major appliances
• Pre-cool your home before peak hours
• Use smart plugs to automatically control devices
• Consider battery storage to avoid peak rates

Off-Peak

6 AM - 4 PM & 9 PM - 12 AM

Moderate energy demand and standard rates

Smart Usage Tips:

• Good time for laundry and dishes
• Charge EVs if super off-peak isn't available
• Run pool pumps and other equipment
• Regular household activities acceptable

Super Off-Peak

12 AM - 6 AM, plus 10AM - 2PM weekends (some plans)

Lowest energy demand and cheapest rates

Smart Usage Tips:

• Best time to charge EVs
• Schedule battery storage charging
• Program smart appliances
• Set pool pumps to run

Seasonal Rate Changes

Summer

(June 1 - October 31)

Higher rates overall due to increased cooling demand

• Peak hours have highest annual rates
• Larger price difference between peak and off-peak
• AC usage significantly impacts bills
• Critical to manage peak time usage

Winter

(November 1 - May 31)

Lower rates overall due to reduced energy demand

• Smaller difference between rate periods
• Peak hours still higher but less extreme
• Good time to establish usage habits
• More flexibility in timing energy use

Holiday Exceptions

SDGE observes certain holidays where peak-hour pricing doesn't apply. These include New Year's Day, President's Day, Memorial Day, Independence Day, Labor Day, Veterans Day, Thanksgiving Day, and Christmas Day. On these days, off-peak rates apply during normal peak hours.

Maximizing Your Savings

The key to saving money with Time-of-Use rates is shifting your energy use to less expensive periods whenever possible. Here are some effective strategies:

Use Smart Technology

• Program thermostats to pre-cool before peak hours
• Use smart plugs to control devices automatically
• Set timers on pool pumps and water heaters

Plan Your Day

• Do laundry and dishes in off-peak hours
• Charge devices overnight
• Cook outside or use a microwave during peak hours
