High Usage Charge

High Usage Charge

To encourage conservation, the state has required that a High Usage Charge be added to the Standard Residential Rate Plan as of January 1, 2017, as part of the residential rate structure adopted by the California Public Utilities Commission (CPUC). This charge applies to residential customers whose monthly energy usage exceeds 400%* of their baseline allowance, which is significantly higher than the typical house uses.

Energy Usage Tier chart: Tier 1 up to baseline allocation = 31 cents per kwh. Tier 2 101-400% of baseline allocation = 40 cents per kwh. High Usage over 400% baseline allocation = 50 cents per kwh.

Every household is provided with a baseline allocation or set amount of kWh of electricity each period – charged at a lower price than energy used above the baseline amount. This reflects the amount of electricity needed to cover your basic energy needs, like lighting, cooking, heating and refrigeration. This varies based on your location.

*For Medical Baseline users on the Standard Residential rate plan, the High Usage Charge applies to customers whose usage exceeds their Tier 2 and medical baseline allowance. Medical Baseline customers receive an additional 16.5 kWh allocation per day in addition to their applicable seasonal baseline for the necessary operation of life-support devices and equipment.

High Usage Charge FAQ

The baseline allowance reflects the amount of electricity needed to cover an essential portion of the energy you use, like lighting, cooking, heating and refrigeration for your area or baseline zone. Your monthly baseline allowance is provided on your billing statement.

About Baseline (Tier 1)

If you are part of our Residential Tiered Plan, your monthly billing period begins in Tier 1. The amount of electricity allocated to Tier 1 is considered the “baseline allocation,” and reflects the amount of electricity, measured in kWh, needed to cover an essential portion of the energy you use, like lighting, cooking, heating and refrigeration. Every household is provided with a baseline allocation or set amount of kWh of electricity each period – charged at a lower price than energy used above the baseline amount. Learn More >

This baseline allocation is established by the California Public Utilities Commission (CPUC) and is based on where you live, the season (winter or summer), and whether your home is “all electric” or uses both electricity and gas. For more information or visit our FAQ's.

Refer to this baseline region map to find which baseline region your home is in, and then reference the chart below. This chart reflects the nine baseline regions within our 55,000 square mile service territory and the daily baseline allocation for Tier 1.
