New TOU Periods for Business

Coffee shop owners review a document while making a call.

Time-Of-Use (TOU) Peak Periods Are Changing

Starting in March 2019 (pending CPUC approval), your TOU periods are changing. This means you can lower your costs by shifting more of your energy use away from these times:

  • Business TOU On-Peak periods will be 4 p.m. to 9 p.m., instead of noon to 6 p.m.
  • Agriculture & Pumping Optional TOU peak periods will be 5 p.m. to 8 p.m.

Why Are TOU Periods Changing?

As California continues to adopt cleaner resources to generate energy, the cost to deliver power throughout the day is changing. Energy is now less costly during midday and more costly in the late afternoon and evening. That’s why TOU peak periods are shifting to these times of day.

Ready for Critical Peak Pricing (CPP)?

In March 2019 (pending CPUC approval), all businesses with service accounts under 200 kW and agricultural and pumping service accounts over 200 kW will default to Critical Peak Pricing (CPP). CPP is a demand response program that offers a discount on regular summer electricity rates in exchange for higher peak period prices during 12 “CPP events” per year between 4 p.m. and 9 p.m. If your business is able to reduce its energy use away from CPP events, you can lower your overall costs.

What is Time-Of-Use?

Our Time-Of-Use rates are part of a statewide initiative designed to keep the electric grid reliable—even when energy resources are in high demand.

All rates feature energy charges that vary based on the time of day, the day of the week, and the season. Some rates also include demand charges that are based on the maximum amount of electricity your business uses at once and during certain times of the day.
