Public Service Electric and Gas Deploys PI System as Foundation for CMMS System

Overview:

Public Service Electric and Gas implemented the SAP PM (Plant Maintenance) system in 2000 to enhance the efficiency of its transmission and distribution equipment maintenance. While this application did improve maintenance systems, it did not provide the proactive, predictive approach to T&D maintenance that the company wanted.

A special project was begun in 2001 to design and implement a computerized maintenance management system (CMMS) that would allow PSE&G to monitor equipment status and handle maintenance procedures using a condition-based approach rather than a calendar-based system. The PI System from OSIsoft in San Leandro, Calif., is the foundation on which PSE&G’s engineering and IT staffs created their CMMS solution. The system proposal called for a full ROI by 2005, but the system was launched in early 2002 and began delivering cost savings in its first year. It also is extending the life of aging equipment through more efficient monitoring of performance.
