Data Management
Foundational Concepts
• Data management improvement is a cross-work team exercise
• Data management improvement requires
– Taking time to develop a long-term vision
– Integration, not application deployment!
– Business process changes
– Continuing attention to data governance
• Quality data management across the Transmission
organization is what enables future solutions and efficiencies

Asset Health Center (AHC) -
Overview
• Purpose of the Asset Health Center (AHC)
– Prevent failures (substation focused to date)
– Optimize maintenance effectiveness
– Support asset renewal prioritization
• AEP’s aging assets need increasing attention
– 33% of transformers > 50yrs; 18% > 60yrs old
– 33% of T-Line > 70yrs; 49% > 50yrs, 72% > 40 yrs old
– Aging assets drive increasing outages, cost
• AHC: Timely & Transformational technology
– Automates condition analysis to support action plans
– Determine health index, remaining life, prioritize risk
• Implementation
– Identified major substation asset condition baseline
– Completed platform 12/2015
– Includes transformers, breakers, select batteries
– Monitors standard on new EHV equipment
– Retrofit monitors being rolled out in stages
– Evaluates & documents replacement need priority
