Beat the Heat & Save: Understanding Time-of-Use Rates in Diamond Bar

Posted on November 02, 2025 by Just Electric Services

Living in Diamond Bar offers a wonderful quality of life – from the beautiful hillside homes in The Ranch to the more traditional styles found in Diamond Bar Boulevard neighborhoods. But with those warm California summers, and even those surprisingly cool winter evenings, keeping your home comfortable can mean higher energy bills. A key factor in managing those costs is understanding how Southern California Edison’s (SCE) Time-of-Use (TOU) electricity rates work. Here at Just Electric Services, serving Diamond Bar and the San Gabriel Valley for over 25 years, we want to help you navigate this system and potentially save money.

What are Time-of-Use (TOU) Electricity Rates?

Traditionally, SCE customers paid a flat rate for electricity, regardless of when it was used. TOU rates, however, charge different prices based on the time of day and the day of the week. The idea is to shift energy usage away from peak demand hours, reducing strain on the grid and lowering overall costs. Here's a breakdown of typical TOU periods (though these can vary, so always check your SCE bill or online account):

  • Peak Hours: Usually 4 PM – 9 PM, Monday through Friday. This is when demand is highest, and prices are the most expensive. Think evenings when everyone's home from work and school, running appliances, and watching TV.
  • Off-Peak Hours: Typically all other times – overnight, early mornings, and weekends. These hours have the lowest rates.
  • Mid-Peak Hours: Usually during parts of the day, like midday, where rates are moderate.

SCE offers several TOU plan options, so it's important to choose the one that best fits your household’s energy usage patterns. If you’re unsure which plan is right for you, don’t hesitate to give us a call. While we’re electrical experts, we can offer insights to help you make informed decisions.

How TOU Rates Affect Diamond Bar Homes

Diamond Bar’s climate, with its hot summers and occasional need for heating in the winter, makes understanding TOU rates especially important. Many Diamond Bar homes feature swimming pools, which can significantly increase energy consumption during peak hours. Similarly, keeping your home cool with air conditioning requires a substantial amount of energy.

Here are a few ways to adjust your habits to save money:

  • Run major appliances during off-peak hours: Wash clothes, run the dishwasher, and do laundry overnight or on weekends.
  • Pre-cool your home: If you have a smart thermostat, program it to cool your home a few degrees before peak hours begin.
  • Charge electric vehicles overnight: EV owners can save a considerable amount of money by charging their vehicles during off-peak hours.
  • Pool pumps: If you have a pool, program the pump to run during off-peak hours.

If you notice flickering lights or any other electrical issues while making these changes, it’s crucial to call a qualified electrician near me. Ignoring electrical problems can be dangerous and costly.
