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
