Customers holding firm BTS capacity will be able to nominate natural gas for delivery in accordance with SoCalGas Rule No. 30, Transportation of Customer-Owned Gas.

Firm and Interruptible Receipt Point Rights

Firm BTS rights allow firm access to the SoCalGas transmission system receipt points. However, these rights do not guarantee nor imply firm service on SoCalGas’ local transmission/distribution system.

Interruptible BTS rights provide “as available” access to the SoCalGas transmission system receipt points. All unused firm BTS capacity or operationally available capacity will be made available on an interruptible basis at the G-BTS4 rate schedule and will be scheduled in accordance with SoCalGas Rule No. 30. Customers taking interruptible service will be required to execute one contract which will provide service from all receipt points.

Off-System Delivery

SoCalGas will contract with any creditworthy party for Interruptible Off-System Backhaul Service under the G-OSD tariff to the PG&E pipeline only. SoCalGas will make available physical displacement capacity at the receipt point on an interruptible basis at the applicable G-OSDI rate.

Pooling Service

Pooling is the administrative aggregation or disaggregation of natural gas supplies at the citygate and receipt point and is defined in SoCalGas’ G-Pool tariff. Each customer may have a single citygate pool contract where they will be able to nominate supplies coming through any Backbone Transportation Service Contract and nominate supplies out of the pool contract to end-users, other pool contracts, off-system, or to storage accounts. The city gate pool contract will be required to balance through each nominating cycle.

Agent Designation for Nominating and Trading Rights

A customer may opt to designate one and only one nominating agent or trading agent in addition to itself at any one time to nominate on all BTSCs under a customer’s RPMA. Customer must provide appropriate written authorization to SoCalGas of its intent to add or change a designated nominating or trading agent via the Nomination and Trading Authorization Form (Form No. 9924). Such designation shall be subject to that agent complying with applicable tariff and contractual provisions. Customer shall provide appropriate written notice to SoCalGas of its intent to terminate a nominating agent via the Termination of Nominating or Trading Agent Form (Form No. 9926).

Buying Backbone Transportation Service Rights

SoCalGas will provide eligible participants the opportunity to buy Backbone Transportation Service Rights before, during, and after the Open Season Process. Open Season Step 1 and Open Season Step 2 customers will receive a packet by mail with their maximum bidding rights based on historical usage and all necessary agreements. All participants will utilize the SoCalGas on-line bidding system for the Firm Receipt Points Access Rights during the Open Season Bidding process. After the Open Season is completed, customers will be able to buy rights via the SoCalGas EBB system- Envoy.

Below are the available Open Season options.

Buy Firm Rights in Step 1 and 2 by accepting the set-asides or bidding rights provided by SoCalGas via the Open Season online bidding system.

Buy Firm Rights in Step 3 via the online bidding system.

Re-contract your awarded rights by exchanging them to a different receipt point.

Open Season Process

The Open Season Process steps are available to eligible creditworthy participants.

Bidding Rights Assignment Form

The Backbone Transportation Service assignment form is designed to allow a noncore customer with bidding rights in Step 2 of the Open Season to assign those rights to a third party (“assignee”). This enables the assignee to bid in Step 2 of the Open Season and be the contract holder of the Backbone Transportation Service rights. The maximum bidding rights would be irrevocably transferred (unless cancelled prior to the Open Season Step 2) to the other party and BTS rights awarded during Step 2 of the Open Season would be held in the name of the assignee. The assignment or transfer of rights is for the entire quantity and term and may not be divided between separate assignees.

The election form must be completed by the end-use customer in order to allow SoCalGas to prepare the contracts, verify credit, and complete other administrative duties necessary for parties to bid for firm receipt point access rights during the Open Season, Step 2. This assignment form is valid only for the 2011 Open Season process.
