Asset Characterization and Performance Information: Asset registries allow the systematic recording of all assets that an organization owns or for which it has responsibility. They provide a repository of all the needed input parameters that an organization needs to know about its assets in order to ascertain their remaining life and economic value. Asset registries are a key element of any asset management program that enables effective fleet management and performance database utilization across the various data sources for underground transmission assets. This site provides an overview of EPRIs development of asset registries for underground transmission assets, including the categorical breakdown and layout of the registry.

Underground Transmission Component and Sub-system Performance Based on Analysis of Industry wide Data: To aid in the understanding of historical performance of underground transmission assets, EPRI continues to collect failure and performance data for underground transmission assets across the industry. This site provides an breakdown of the number of records collected to date for different underground system and component types, and includes an example of some key analysis plots of the collected data.

Underground Transmission System Risk Assessment: Due to the nature of underground transmission systems the collection of condition assessment data on underground assets is often limited. EPRI is exploring the use of readily available data sources (such as alarm data, maintenance records, and others) to in risk assessment of underground transmission systems within a utility. This site provides an overview of a utility use case where EPRI evaluated the use of alarm data to understand performance of underground transmission circuits across the system.
