Tiered Rate Plan

Tiered Rate Plan

In the Tiered Rate Plan (Schedule D), you begin each billing period at the Tier 1 rate, which has the lowest price per kilowatt-hour (kWh). If you use more energy than the baseline allocation for your region, your rate climbs to Tier 2. A state-mandated High Usage Charge may also apply.

The Tiered Rate Plan is a more traditional billing plan where the best way to keep energy costs low is to limit your total energy consumption.

To see which tier you are currently in:

  1. Log into My Account.
  2. Select the “View Recent Usage” button.
  3. Select “How is this calculated?” which is below your “Projected Next Bill” total.

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.

Tiered Rate Plan

Each billing period begins at the Tier 1 rate, which has the lowest price per kilowatt-hour (kWh). Current rates as of 01/01/23

The rates shown reflect pricing for customers that receive both delivery and generation services from SCE. If you are receiving your generation services from a provider other than SCE, your rates may differ. For generation costs, please contact your Community Choice Aggregation Service Provider or Direct Access Electric Service Provider for more details.

  1. Identify your baseline region number. Regions have different rates based on their average climate conditions.
  2. Use your region number to look up your daily baseline allocation. Your daily baseline allocation is different during summer months (June-September) than the rest of the year.

    Summer Daily Allocations (June through September)

    Baseline Region Number Daily kWh Allocation All-Electric Allocation
    5 17.2 17.9
    6 11.4 8.8
    8 12.6 9.8
    9 16.5 12.4
    10 18.9 15.8
    13 22.0 24.6
    14 18.7 18.3
    15 46.4 24.1
    16 14.4 13.5

    Winter Daily Allocations (October through May)

    Baseline Region Number Daily kWh Allocation All-Electric Allocation
    5 18.7 29.1
    6 11.3 13.0
    8 10.6 12.7
    9 12.3 14.3

    15 9.9 18.2
    16 12.6 23.1

    Additional Information:

    • All-electric households have a different baseline allocation.
    • Medical Baseline customers receive an additional 16.5 kWh allocation per day for the operation of life-support devices and equipment.
    • The summer season begins at 12 a.m. on June 1 and continues until 12 a.m. on October 1 of each year. Winter rates apply for the rest of the year.

    Climate Zone details:

    • Hot: 13, 14, 15
    • Moderate: 5, 9, 10
    • Cool: 6, 8, 16
    • Climate Zone 10 is a moderate zone but has hot summer weather. This distinction is made in relation to CPUC Code Section 745.d.2.
    • ZIP codes do not correlate with Climate Zones
  3. Use your daily allocation to calculate your monthly baseline allocation.
    [Daily Baseline Allocation] x [# of days in billing period] = Monthly Baseline Allocation
  4. Use your monthly baseline allocation to calculate your costs for each tier.

    Tier 2 Allocation:

    Rates are subject to change.
    Other charges will appear on the bill.

Baseline Allocation

An amount of electricity (measured in kilowatt hours) that is provided to households at a lower rate than electricity used above this threshold.

Baseline allocations are determined by the California Public Utilities Commission (CPUC) based on the number of days in the billing period, the season, the climate, and whether your primary source of heat is electric.

Baseline Allocation (Daily/Monthly)

Since billing periods can have different numbers of days, the baseline allocation is defined initially as a daily allocation. This is then calculated into an allocation for the entire billing period, which is sometimes called a “Monthly Baseline Allocation” for convenience.

Baseline Credit

A discount that reduces total electricity charges. A baseline credit is calculated per kilowatt hour (kWh) used and is capped by the monthly baseline allocation.

Daily Basic Charge

A flat, daily charge that is billed on a monthly basis, regardless of customer use or activity.

Kilowatt Hour (kWh)

A unit of measurement for electrical energy consumption over time that we use to compute billing. One kilowatt hour is equivalent to using 1,000 watts for 1 hour.

Minimum Daily Charge

A flat, daily charge that is applied if a customer’s total delivery charges fall below a minimum in a billing period (about $10 for a typical residential user). This charge supports the maintenance and operation of providing electricity.

Tier

An amount of energy allocated to a customer in a billing period at a specific price. If a customer uses more energy than what is allocated, they are charged at a higher rate on the next tier.

Tiered Rate & Baseline Allocation FAQ

By logging in to My Account, you have access to a number of tools and services, including a chart that tracks which tier you’re currently in (as of the previous day), and the tier you’re expected to fall into by the close of the current monthly billing period.

The information provided in the chart is customized based upon your specific electricity use and is updated daily. Because the electricity usage is updated daily, the costs are also updated daily. This chart also provides current tier pricing, and the amount of electricity allocated to each tier. This can be a valuable resource to help you better understand the rate structure and more effectively manage your monthly bill.

Log in to My Account to access the chart, then select the "View Recent Usage" button, and then "How is this calculated?" which is located below your “Projected Next Bill” total.

Each city within our service territory has been assigned to a baseline region which corresponds to the primary climate associated with that geographic area. The climate zone for each city can be found in the Index of Communities.

A map of the baseline regions also depicts how the baseline regions align with coastal, inland and desert geographies.

Medical Baseline customers have an additional 16.5 kilowatt hours (kWh) allocated to their baseline usage on a daily basis, in addition to their applicable seasonal baseline for the operation of life-support devices and other qualifying equipment.
