Efficient Management of Electric Transmission Assets
Recent Events •August 14, 2003 ‘collapse’ of Northeast Electric Grid •Affected 50 million people •Three major contributing factors •Inadequate Transmission Capacity •Insufficient real time monitoring •Inadequate system maintenance
Efficient Management of Electric Transmission Assets
Public Service Company of New Mexico’s System: • New Mexico’s largest Investor Owned Utility • Provides both Electric and Gas Service • 370,000+ electric customers • Ranked #1 in reliability by EEI in 2002 • Approximately 2,800 miles of Electric Transmission
Efficient Management of Electric Transmission Assets
•Corporate Philosophy: • Implement Automation to Help Maximize Return on Assets •Utilize existing applications where they make sense •Develop custom applications when necessary •Leverage GIS technology whenever possible
Efficient Management of Electric Transmission Assets
•Examples of Utilizing Automation at Public Service Company of New Mexico • eTAMIS – a GIS System combined with Automated Inspection and Maintenance capabilities for Electric Transmission facilities • gTAMIS - a GIS System combined with Automated Inspection and Maintenance capabilities for Gas Transmission facilities • ALPS – Automated Line Patrol System developed for Electric Distribution facilities • BC_LAMPS – Street Light inventory, billing, inspection and maintenance program
