This page is for customers interested in transferring intrastate curtailment quantities under the provisions of SoCalGas ’Rule 23.

The information posted was provided by customers, including all contact information. Postings by SoCalGas are intended solely to facilitate intrastate curtailment transfers for customers of SoCalGas. No representation is made by SoCalGas as to whether or not a transfer arrangement of any curtailment quantities will, in fact, be completed.

Further, SoCalGas has no responsibility or liability regarding contacts made or arrangements completed as a result of the posting. Customers are responsible for any errors in the information provided. Postings are subject to all applicable laws and regulations.

The Curtailment Transfer Process 

Customers may make arrangements to transfer or “trade” curtailment requirements. Through such an arrangement, responsibility for a specified curtailment level can be transferred from one customer (who otherwise would be required to curtail) to another customer (who would not otherwise be required to curtail).

Customers who reach mutual agreement on a transfer of curtailment requirements must execute a “Notice of Intrastate Curtailment Transfer” (Form No. 6600) (This is a sample document, not for actual use.) and submit this form to The Gas Company. The form must indicate the customer facilities involved in the trade and must specify the amount of curtailment to be transferred between each. Transfer arrangements are not valid until the required form is accepted and agreed to by The Gas Company. Accordingly, customers should submit their curtailment trades as early as possible. A copy of the transfer form may be obtained by contacting your Gas Company account executive

Noncore customers can express their interest in transferring intrastate curtailment requirements with each other and obtain each other’s contact information by adding their names to the curtailment.

Curtailment Background Information 

General

From time-to-time, The Gas Company may need to interrupt service to its customers. The tariff provisions governing the process of service interruption or “curtailment” are set forth in Tariff Rule 23, “Continuity of Service and Interruption of Delivery." 

(Note: While The Gas Company exercises reasonable diligence and care to furnish and deliver service to its customers, it is not liable for damages resulting from any failure to deliver gas or provide service, which failure results from breakage of its facilities, operating limitations or other conditions beyond its reasonable control.)

The situations requiring curtailment vary but generally fall into these categories:

  • General or “System” Curtailment
  • Emergency Curtailment
  • Localized Curtailment

The purpose of this overview is to help you better understand the general provisions of curtailment. It is not intended to be a substitute for Rule 23 or the other tariff schedules The Gas Company has on file with the California Public Utilities Commission (CPUC). All of these tariffs can be reviewed online.

Order of Curtailment

In the event of a system curtailment, The Gas Company shall curtail service throughout its service area in the following order:

  • Interruptible noncore standby procurement service
  • Firm noncore standby procurement service
  • Unbundled as-available storage withdrawal services
  • Interruptible noncore intrastate transmission service
  • Firm noncore intrastate transmission service
  • Unbundled firm storage withdrawal services
  • Priority 2A (or “large”) core service to non-residential customers
  • Priority 1 (or “small”) core service to non-residential customers
  • Priority 1 core service to residential customers

Emergency Curtailment

The Gas Company may need to curtail service on an emergency basis. This occurs at times where there is a threatened or actual shortage creating an emergency condition for a short duration in The Gas Company’s ability to meet the demands of core customers. During such an emergency, The Gas Company may curtail service to all or some of its customers in the most reasonable and practicable manner possible. Further, in such an emergency, The Gas Company shall have the right to shut off, discontinue, re-establish, or continue service to such customers, irrespective of the priority or preference set forth in its tariff schedules, contracts, or rules and regulations applicable to such service.

Localized Curtailment

The Gas Company may need to curtail service in a specific area of its service territory due to intrastate capacity restrictions or emergencies. In such an event, curtailment of service to customers in the affected area will generally be made based on the order of curtailment shown above (and specified in Section C.1 of Tariff Rule 23). However, this order will be followed only to the extent it is operationally feasible to do so. Given the nature of the localized constraint, customers in unconstrained areas may receive service while other customers or equal or higher priority are curtailed or interrupted. Unbundled as-available and firm storage withdrawal service may not be available for deliveries to customers whose service is restricted as a result of a localized curtailment.

Noncore Interruptible Service

Noncore interruptible service to affected customers will be curtailed by percentage of default rate paid, with customers paying the lowest percentage of default curtailed first. Customers paying the same percentage of default rate will be curtailed on a pro rata basis with the exception that all affected UEG service shall be curtailed before affected cogeneration service.

Noncore Firm Service

Noncore firm service to affected customers will be curtailed by the rotation mechanism described in Section C.2 of Tariff Rule 23. For determining the order of curtailment, firm service customers shall be separated into two lists. The first list shall contain all UEG and cogeneration customers (UEG listed first) and the second list shall contain all other firm service customers. The order of customers on each list shall be established by random lottery. The Gas Company shall aggregate the listed customers into blocks of approximately 20 MMcfd, to the extent possible ).

(Note: Customers with peak-day usage of 20 MMcfd or more shall remain separately listed as one curtailment block.)

The blocks to be curtailed shall be established by 1) selecting the first block from one list, 2) selecting the first block from the second list, and 3) continuing the selections down the two lists until the necessary level of curtailment is reached. Additional curtailment of firm service or (or the next firm service curtailment) will begin with the customer block immediately following the last block selected.

Curtailment Notice

The Gas Company shall provide notification of a curtailment to the contact personnel indicated on the Personnel Notification Form most recently submitted by the customer. Curtailment notification shall be provided by any one or more of the following means: verbally by telephone or in person; in writing via electronic mail, facsimile machine, or overnight postal delivery; or by text message sent via an alphanumeric pager system. The Gas Company will attempt to provide advance notice of a curtailment but only to the extent it is practical to do so. In some situations, The Gas Company may need to curtail your service immediately upon notification of the curtailment. In this event, the customer shall be required to curtail or will be found in violation of curtailment.
