Learn how to read and understand the information presented on your monthly natural gas bill.

We want to make it as easy as possible for you to read and understand your natural gas bill each month. If you have questions about how your bill is calculated or what's included on it, the following information should help clarify.

First, let's look at a sample natural gas bill.

How Natural Gas Bills are Calculated

Natural gas rates are made up of two primary charges:

  • Natural gas delivery service: the "delivery" (or "transmission") charge.
  • The cost of the natural gas itself: reflected in the "procurement" charge.

Some people think that SoCalGas® produces natural gas, but we don't. For our residential and smaller business customers, we buy natural gas from producers and marketers at the best possible prices on the open market, meaning we don't benefit from higher natural gas prices.

Commodity Charge

The wholesale natural gas prices we pay are based on market supply and demand. They're not marked up by SoCalGas, and are shown on your monthly bill as the "commodity charge." SoCalGas' delivery service charge covers the cost of transporting natural gas through our pipeline system. It is approved annually by the California Public Utilities Commission (CPUC) and is not impacted by the price of natural gas.

With monthly pricing, natural gas rates are based upon a 30-day forecast of natural gas market prices. This gives customers a better picture of the current price of natural gas, and means they no longer have to wait for annual adjustments to their bills to make up for differences between the 12-month forecast price and the actual price paid by SoCalGas on a monthly basis.

Billing Term Definitions

  • Baseline: Amount of natural gas billed at the lowest residential rate.
  • Billing Factor: Adjusts for differences in elevation, delivery pressure and the heating content of natural gas.
  • Climate Zone: Weather zone in which a customer lives. Colder zones receive more baseline allowance.
  • Customer Charge: Charge to recover costs of natural gas delivery, including reading meters, preparing bills and processing payments.
  • Natural Gas Commodity Charge: Cost of natural gas purchased by SoCalGas on behalf of its customers.
  • Misapplied Payment: A debit or credit given to correct payment(s) processed to a customer's account in error.
  • Payment Due Date: Payment due date shown on the front bottom portion of the bill is for current charges only; it does not stop collection activity on an unpaid previous balance.
  • Public Purpose Surcharge: Charge to fund Public Purpose Programs such as California Alternate Rates for Energy (CARE), Energy Savings Assistance Program (ESAP), energy efficiency and research and development. CARE customers are excluded from paying the CARE portion of the surcharge.
  • Rate: Identifies the rate schedule used to calculate your bill. You may review these rate schedules at a local office of SoCalGas or at socalgas.com.
  • State Regulatory Fee: A fee used to fund the California Public Utilities Commission. Each customer's fee is determined by the number of therms used.
  • Therms: Standard unit of measuring heat energy.
  • Transportation Charge Adj: An adjustment to transportation charges that applies to all customer classes that participate in the California Alternate Rates for Energy (CARE) program, and customers who are exempt under the United States Constitution or California Constitution as referenced in Section 896 of the Public Utilities (PU) Code.
  • Utility Users Tax: Tax charged by some cities and counties based on the amount of the current monthly natural gas bill. These cities and counties require SoCalGas to collect this Utilities Users Tax for them.

Natural Gas Conversions

  • 1 cubic foot = 1,050 Btu
  • Therm = 100,000 Btu
  • Ccf = 100 cubic foot, or 1 therm
  • Mcf = 1,000 cubic feet = 10.20 therms
  • MMcf = 1 million cubic feet
  • Bcf = 1 billion cubic feet
  • Decatherm (Dth) = 10 therms = 1 million Btu
  • Mmbtu = 1 million btu = 10 therms

Baseline Therm Allowance

As determined by the California Public Utilities Commission (CPUC), under the direction of the State Legislature, "baseline therm allowances" are the amounts of natural gas needed to meet the minimum basic needs of the average home. SoCalGas is required to bill these "baseline" amounts at its lowest residential rates. The goal of these "baseline" amounts is to encourage efficient use of natural gas.
