Terms A-Z


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 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.

Scheduled Outage

The shutdown of a generating unit, transmission line, or other facility, for inspection or maintenance, in accordance with an advance schedule.

Service Area

A geographic area where a utility provides service, usually under provisions of a franchise, charter or certificate, and subject to special government regulations.
