NGT&S – History (1998)NGT&S – History (1998)

1998 - Gas Control– Limited real time data availability

• Limited electronic historian• Paper SCADA logs• Physical archives

– Fall 1998 - PI Arrives• Long Term electronic historian• Instantaneous $37,000 savings in mainframe and

tape costs• PI Client tools – PI ProcessBook & DataLink

– 300 hour time savings– Faster data request resolution


NGT&S – History (2000)NGT&S – History (2000)

Two Years later - 2000– PI Data use has moved outside Gas Control

Groups accessing PI Data– Environmental Health and Safety– Facility Planning– Field Services– Marketing
