Direct Access

Direct Access (DA) was suspended in September 2001.  Under the suspension, existing DA customers could continue in the program, but no new customers were eligible.  In October 2009, a new law provided for a limited re-opening of DA that SDG&E implemented in April 2010.  The limited re-opening is available only for non-residential customers and the amount of customer usage that can transfer to DA is capped.

Updated February 15, 2018

SDG&E’s Total DA Load Allowance is 3,562 GWh.

All certified 6-Month Notices to Transfer to Direct Access Service (6-Month Notices) received during the June 2016 enrollment period have been placed on the Y2017 Wait List.  The lottery process and the Wait List notification were completed August 12, 2016.  The Y2017 Wait List is in effect January 1, 2017 and expires December 31, 2017.  For additional detail, see D.12-12-026 dated December 20, 2012.

The next Direct Access Enrollment Period will be held the second full week of June 2017.  SDG&E will begin accepting Six Month Notices to Transfer to Direct Access on Monday, June 12, 2017 at 9:00 am Pacific Daylight Time (PDT).  Customers or their authorized agents may submit Six Month Notices during the five (5) business days beginning June 12th and ending Friday, June 16, 2017 at 5:00 pm PDT.  SDG&E will establish the Wait List for any DA load that may become available under the Overall DA Cap during calendar year 2018.

Disclaimer information

Sempra Energy Solutions, LLC and Sempra Energy Trading, LLC, are not the same company as the utility, San Diego Gas & Electric (SDG&E) and Sempra Energy Trading, LLC and Sempra Energy Solutions, LLC, are not regulated by the California Public Utilities Commission.


California gas industry restructuring began in 1988, when the California Public Utilities Commission (CPUC) issued the first of many rate design changes in an effort to open the natural gas market to competition.

The first change separated the California gas market into core and noncore customer segments, depending on the customer's load, end-use priority, and economic ability to use alternative fuels.

The noncore customers were provided with the ability to elect natural gas service from a Gas Service Provider (GSP) instead of the utility. The utility still provides these customers with the transportation of the gas across its distribution system to the customer's meter.

In 1991 additional rate design changes were implemented. One of those changes gives core customers the ability to elect commodity services from GSPs through a Core Aggregation Transportation (CAT)program. Other significant changes have been implemented which opened interstate pipeline capacity and gas storage services to competition.

The road to gas industry restructuring has not reached its end. We anticipate continued rate design changes to occur in order for the CPUC to reach its ultimate goal of providing all gas customers with a greater competitive gas marketplace.

Current definition of gas customer segments

Core Customers

Core customers include all residential, regardless of load size, commercial customers with annual loads below 250,000 therms, and those commercial customers with annual loads above 250,000 therms who elect to receive the higher reliability associated with core service.

Noncore Customers

Noncore customers include all cogeneration, regardless of load size, and those commercial customers with annual loads above 250,000 therms. 250,000 therms are approximately equal to an annual monthly average usage level of 20,800 therms.

To Become A Participating Gas Service Provider

Please send your questions to [email protected].

Receiving your natural gas service from a third-party Gas Service Provider (GSP) is serviced through the Core Aggregation Transportation Service.

Core Aggregation Transportation (CAT)

The CAT program gives customers the option to purchase natural gas from gas marketers, also known as aggregators. The following customers are eligible for the program.

  • Customers using 250,000 therms or less per year

  • Residential customers

  • Natural gas vehicle customers

Signing Up for Service

If you are interested in receiving Core Aggregation Transportation Service, first contact a Gas Service Provider (GSP) and discuss your options.

If you decide on this service, the GSP will submit a gas direct access service request (DASR) to SDG&E to switch your account to the Customer Choice Program.

Your GSP will need the following:

  • Billing account

  • Meter number

  • Service address

You can find this information at the top of your SDG&E bill.

Residential customers have 30 days after they receive their first bill from their supplier to cancel their enrollment in the CAT program.  Contact your service provider or SDG&E to request a termination of third party gas services.

Changing to a Different Gas Service Provider

Initially, customers commit to participate in the Customer Choice Program for one year. After the first year, customers can switch to a different GSP or return to SDG&E procurement services. The agreement with your GSP should outline any cancellation process and conditions.

If your GSP terminates service to customers or goes out of business, you will return to SDG&E’s procurement service.

90 Days Termination and Switch Conditions

Customers have up to 90 days from the termination effective date to switch to another GSP. After 90 days, if the customer has not chosen a new GSP, the customer must continue to receive gas procurement service from SDG&E for a total of 12 months before being eligible to return to service under the Customer Choice program.

Términos y condiciones

These programs are approved by the California Public Utilities Commission (CPUC) and may be modified or terminated at any time. The CAT Program is subject to Tariff Rule No. 32 and other applicable tariffs and CPUC decisions that are in effect from time to time.

Noncore customers are large commercial customers with annual monthly average usage equal to or in excess 20,800 therms that have not elected core service.

SDG&E's natural gas distribution system is designed to serve its core customers on a cold-year, peak-day. Noncore customers use the gas distribution system on an as-available basis.

Non-Core Gas Curtailment

If the system is being fully utilized by core customers or some other event arises which may jeopardize service to core customers, noncore customers will be required to discontinue their use of natural gas. All noncore gas customers have automatic meter reading (AMR) installed that allows SDG&E to record their usage on an hourly basis.

The charges for noncore customers who do not comply with a gas curtailment request are:

  • $1.00 per therm during the first 5-hours of the curtailment

  • $3.00 per therm during the next 3-hours of the curtailment, and then

  • $10.00 per therm for all usage during the curtailment event beyond 8-hours

If a noncore customer fails to comply with a request to curtail by the end of the 48th consecutive hour of the curtailment event, it will be reclassified to core status for a minimum of one-year.

Due to the lower reliability of service provided to noncore customers the average gas transportation rate charged to noncore customers is lower than the average transportation rate charged to core customers.

Gas Service Providers – Noncore

Noncore customers must either accept responsibility for managing their own gas procurement, scheduling, balancing, and certain transportation needs independently or through an assigned agent, or arrange to have these needs fully managed by a Contracted Marketer (“CM”).

Request For Retail Noncore Gas Services Agreement

The information provided below explains the noncore gas service options available to eligible SDG&E customers and provides step-by-step instructions for completing the noncore service agreement.

After you have entered the appropriate customer information requested in the top section of the first page, proceed to Step [1]. If you do not know your account number or gas meter number, contact your account representative or SDG&E’s Customer Contact Center.

A critical piece of customer information requested on the first page of the noncore service agreement is the identification of the appropriate "primary" and "alternate" gas curtailment contact names and phone numbers.

Noncore customers are required to keep SDG&E informed of any changes to the gas curtailment contact information provided in their "Request For Retail Noncore Gas Services" agreement.

Step One: Request For Core Classification

As an eligible noncore customer, you have the option of electing core service. If you decide to take core service and you want SDG&E to provide bundled gas transportation and commodity supply, please indicate your preference by circling “A” Core Bundled Service.

If you prefer to purchase your gas supply from a third party, please circle “B” Core Transportation-Only Service. In order to elect core transportation-only service, you and your gas supplier must follow the procedures set for the in SDG&E’s gas rule 32.

After making your core service election, skip to Step 7, sign and date on the last page and return the entire set of pages contained in the agreement to SDG&E.

If your choice is to take noncore service, circle “No” (which simply means you are not requesting core service) and proceed to Step 3.

Step Two: Noncore Meter Service Pressure

This section will be completed by SDG&E. The price of noncore gas transportation service may vary based upon whether the customer receives service at medium, high, or transmission pressure level.

The rate for unregulated high-pressure (service from a SDG&E gas pipeline rated above 99 psig), or transmission-level (service from a SDG&E transmission rated gas pipeline, typically above 400 psig), is lower than the rate for regulated service from a pipeline rated at or below 99 psig.

Customers located adjacent to a high-pressure or transmission-level rated SDG&E pipeline may request service at a pressure other than medium. Medium pressure service is typically provided at a rating of 60 psig.

Step Three: Electric Generation (EG)

If you use natural gas to produce electricity, this section must be completed. If you do not use natural gas for the production of electricity, skip to step 4.

  • Check the first box if the entire amount of gas through the meter is used for the production of electricity

  • If the gas meter serves an electric generation unit and other load, check the second box and enter the electric generation unit’s average heat rate in the space provided. The heat rate will be used to determine the amount of gas used to generate electricity.

  • If the heat rate is not provided, or the one provided cannot be verified by SDG&E, the default heat rate of 10,600 Btu per kWh (or 0.106 therms per kWh) will be used.

  • If the annual monthly average volume of excess gas is equal to or greater than 20,800 therms, you may elect to have the excess gas delivered under noncore transportation service, otherwise all excess gas will be billed on the appropriate core rate.

  • A customer generating electricity with a qualifying cogeneration system (must meet efficiency standards set forth in PU Code, Section 218.5) may also have excess gas delivered under noncore transportation service if the gas is consumed by a standby boiler used only when the cogeneration system is not operating.

Step Four: Intrastate Transportation Election

Check the appropriate box for Bundled or Unbundled intrastate transportation service.

Bundled Intrastate Transportation Service

Provides for noncore transportation service from the California border, across the Southern California Gas Company’s pipeline, and through the SDG&E pipeline system to the customer’s meter.

Customers electing bundled service will be billed only by SDG&E and will receive one bill for gas transportation service.

The bundled transportation rate for electric generation customers is Schedule EG. The bundled transportation rate for non-electric generation is Schedule GTNC.

Step Five: Self-Procurement Service

Due to regulations imposed by The California Public Utilities Commission, SDG&E is not authorized to provide gas procurement services to noncore customers. As a result, noncore customers are required to purchase their gas commodity from a supplier other than SDG&E. Please provide the requested information regarding your gas supplier in this section.

In order for SDG&E to provide third parties with access to usage data, customers must provide the appropriate authorization. This authorization will also allow gas suppliers to perform other services, as specified. Please identify the name of your gas supplier/marketer, their phone number, fax number and e-mail address.

If at a later date, you wish to switch your gas supplier, customers are required to provide SDG&E with a minimum 15-days advance written notice (mail/fax to Rate Support). The notice must include the new gas supplier/marketer's name, phone number, fax number, and e-mail address. A change in gas suppliers must become effective on the first day of the selected calendar month.

Franchise Fees are paid by SDG&E to municipalities for the nonexclusive right to install and maintain gas transmission and distribution pipelines and equipment on public rights of way. When customers self-procure their gas supply, SDG&E is required by law to collect a municipal surcharge which is found in SDG&E’s rate Schedule GP-SUR.

Changes to Schedule GP-SUR are submitted to the CPUC on a monthly basis along with SDG&E’s monthly gas rate changes. Charges associated with Schedule GP-SUR appear on self-procurement customers gas transportation bills as a separate line item.

Step Six: Additional Terms and Conditions of Service

Sequence 01

Used for awarding any core volumes that might also be served through the same meter that serves noncore volumes.

Sequence 02

May only be filled out during an open season. Firm awards will be determined at the close of open season when firm service requests are compared with available firm capacity.

If, during an open season you select sequence 02 volumes for firm noncore service, you will be subject to use-or-pay charges. Firm service volumes can not be requested except during an open season typically held in February.

You must use at least 75% of your firm volumes in order to avoid use-or-pay charges. Use-or-pay charges will be based on the difference between what was used and 75% of the contracted volume and charges at 80% of the applicable transportation rate.

If you would like to aggregate accounts for the purposes of use-or-pay, please indicate the accounts to be aggregated on page 3.

Sequence 03

The section new noncore customers will typically be filling out. A minimum of one therm is required regardless of expected use. There are no use-of-pay obligations associated with interruptible volumes.
