Conceptualization & development of unified Asset Performance Management (APM) framework in POWERGRID.

Asset-intensive transmission utilities are increasingly challenged to maintain high reliability while optimizing lifecycle costs across geographically dispersed and heterogeneous asset portfolios. Power Grid Corporation of India Limited (POWERGRID), one of the world’s largest transmission utilities, has initiated a unified Asset Performance Management (APM) framework to enable risk-informed, data-driven asset management at national grid scale. This paper presents the conceptualization and development of a unified APM framework integrating heterogeneous Information Technology (IT) and Operational Technology (OT) data sources, such as SCADA, IoT-based condition monitoring systems, protection systems, Data historian,
