Knowledge
Compilation of underground practices and training
An often-cited challenge for operators of underground systems is the loss of intuitional knowledge due to employee attrition. This challenge is particularly pronounced in urban underground and network systems, where knowledge is often held by relatively few individuals. This area of research seeks to identify, document and share institutional knowledge of underground systems through the development of references, information repositories and training. This research area includes regular updates to the EPRI Underground Distribution Systems Reference Manual (The Bronze Book) and the EPRI Underground Practices repository, a compendium of industry practices for managing underground systems.
