Gas Control, Spectra Energy's high-tech computer control centers, monitor the flow of gas through our U.S. pipelines and the 330 miles of the Maritimes & Northeast pipeline in Canada. Staffed 24 hours a day, seven days a week, the centers collect data from all of these pipelines so that we will always know what is happening along its system.
In addition to monitoring the flow of the natural gas with the use of Supervisory Control Data Acquisition (SCADA), we monitor pressures and temperatures as well as the operating status of all its facilities. Gas Control monitors and reacts to equipment malfunctions, and, when necessary, dispatches Spectra Energy employees who live and work along the pipeline to respond to a malfunction or alarm. As an added safety measure, we've installed remote control equipment on 350 valves along our pipeline system, enabling us to operate them remotely from Gas Control.
