Understanding Your Bill

4 min read

Overview

Every month, solar power is generated by the project connected to your solar subscription. The amount of solar energy produced directly results in discounts to your monthly electricity bill. This document explains how community solar interacts with your bill.

Before We Begin

To better understand your bill, it helps to understand how electricity consumption is measured and the charges based on that consumption.

  1. How Electricity Consumption is Measured
    Every time you turn on a light bulb or plug in a device in your home, you are consuming electricity. The rate of power a device uses when it is turned on (or plugged in) is measured in watts(W) or kilowatts(kW). 1000 W = 1 kW. The rate of power a device consumes over time is measured in kilowatt-hours (kWh).
  2. How Your Bill Relates to Electricity Consumption
    Your utility bill depends on a number of factors, including your electricity rate plan (examples include time of use (TOU) rate, fixed rate, or tiered rate), along with fees, taxes, and adjustments specific to your utility company and geographical location. Look at your electricity bill to see a breakdown of your electricity costs.

Your Utility Bill + Community Solar

The following section will help you understand your bill as it exists now and changes that will be added once you sign up for community solar. Use the sample bill provided by your utility company to help follow along.

Sections of Utility Bill

Portland General Electric sample bill
Pacific Power sample bill
Idaho Power sample bill
  1. Normal utility bill charges
    These costs are based on your electricity consumption, taxes, fees, and adjustments—not solar energy production! After signing up for community solar, you will continue to be billed for the amount of electricity you consume every month per its normal schedule.
  2. Bill Credits
    As a subscriber, you will earn bill credits on your electricity bill for your portion of energy generated by the solar project in the previous month. Since these rates are per kilowatt-hour (kWh), subscribers should expect to see some variance in their total bill credits month to month depending on how much electricity was generated in that month. Bill credits are applied according to a per-kWh rate ($/kWh) determined by your utility company. Rates can be found in the table below.

    Tier 1 Bill Credit Rates by Utility ($/kWh)

    Portland General Electric

    Pacific Power

    Idaho Power

    These rates are fixed for projects participating in Tier 1.

    Tier 2 Bill Credit Rates by Utility ($/kWh)

    Utility

    Portland General Electric

    Pacific Power

    Effective Date

    Residential

    $0.0977

    1/25/2022

    Non-residential

    $0.08793

    1/25/2022


    Tier 2 bill credit rates will escalate 2% each year beginning in April 2023 for both residential and non-residential customers. This is only applicable to Portland General Electric and Pacific Power customers.

    You can find out if your project is Tier 1 or Tier 2 by asking your project or subscription manager.

  3. Project Subscription Fees
    Subscription fees vary by solar project and are set by project managers. Ask the project or subscription manager. You can also find a project’s subscription fee on the description page for each project listed on the Project Finder. Like bill credits, subscription fee totals will vary somewhat each month, since they are calculated per kWh. Discounted subscription fees are available for low-income subscribers. Some projects may offer an ownership option for upfront investment instead of a monthly subscription.
  4. Program Administration Fees

    Program administration fees recover the costs of operating the program. You will see individual line items on your utility bill: one for the fee that recovers the costs of the program administrator and one for the fee that recovers the costs of the electric utility. Program administration fees are additional to the subscription fee that is paid to the manager of the solar project you choose. Low-income customers are exempt from paying all program administration fees and will not see program administration fees on their bill.

    Current program administration fees are provided in the table below. While the bill credit and subscription fee are based on variable solar generation, the program administration fees are fixed monthly amounts based on the size of your subscription and calculated on a $/kW-AC basis. Program fees are set and reviewed annually by the Oregon Public Utility Commission, and may be updated to reflect program administration costs.

    Fee Component

    Portland General Electric

    Pacific Power

    Idaho Power

    Program Administrator Fee

    $0.85

    $0.85

    $0.20

    $0.48

    Total Program Fee

    $0.96

    $1.05

    $1.33

  5. Total Utility Bill
    Your total electricity bill is calculated by subtracting your solar discounts from your electricity costs and fees.

Total Savings

A customer’s overall savings will depend on the subscription fees charged by their project manager and their subscription size. To learn more about how this works, please refer to the Oregon Community Program Bill Impact Calculator or ask your project or subscription manager for an estimate.
