- Sales for Resale
Sales made to a local distribution company, pipeline, or municipality where the gas will be resold by the purchaser.
- Sales Level
The sales volume being applied to the cost of service to develop rates. See TRANSPORTION LEVEL, THROUGHPUT LEVEL.
- Sales Refund Objective (SRO)
A provision included in many prior settlements, and often examined by Staff, that if actual volumes exceed an agreed level during the period of time the rates are in effect, the pipeline agrees to refund the fixed costs received in the commodity rate. The SRO can be offset by increases in certain jurisdictional costs. The SRO has not been used with the Modified Fixed Variable classification method.
- Sales, Interdepartmental
Sales to other departments of a company (gas, electric, steam, water, etc.) and dollar value of such sales if the charges are at tariff or other specified rates for the energy supplied.

Standard Cubic Feet
A process by which nominations are first consolidated by receipt point, by contract, and verified with upstream/ downstream parties. If the verified capacity is greater than or equal to the total nominated quantities, all nominated quantities are scheduled. If verified capacity is less than nominated quantities, nominated quantities will be allocated according to scheduling priorities.
- Scheduling Coordinator
Submits balanced schedules and provides settlement-ready meter data to the independent system operator. The scheduling coordinator also settles with generators and retailers, the PX and the ISO; maintains a year-round, 24-hour scheduling center; provides non-emergency operating instructions to generators and retailers, and transfer schedules in and out of the power exchange, or PX. The PX itself is considered a scheduling coordinator.
- Scheduling Penalty
A monthly or daily penalty assessed on the difference between the volume scheduled to be tendered by the shipper to the pipeline and the volume actually tendered for delivery. The purpose of the penalty is to maintain high throughput on the pipeline and prevent disruption of deliveries to other transportation and sales customers. Because the damage caused by the shipper failing to tender scheduled volumes cannot be remedied after the fact, there is no notice or make-up period involved.
A device used to clean deposits of paraffin or other foreign substances from tubing or flow lines. See PIG and RABBIT.
