Outage Management System for Hydro One Networks (ORMS)

Hydro One Networks (Hydro One) is a transmission and largely rural distribution utility in Ontario, Canada.  Over 1.2 million customers are supplied by their distribution network.  To improve the effectiveness of their Distribution Operations Management Centre, Call Centre and field operations, Hydro One implemented an OMS named "Outage Response Management System" (ORMS) in February 2003.

ORMS automates trouble call entry, analysis and voice dispatch.  It is built with CGI/M3i's outage management and dispatch software with interfaces to a Customer Information System (CIS), Interactive Voice Response system (IVR), Autodialer, and web-based reporting system.  The electrical model for the system was constructed by geo-referencing the facilities (switches and transformers) in a topology model to a set of operating maps.

The Role of ExtenSys

ExtenSys was invited to participate in the OMS project with Hydro One Networks. ExtenSys assisted Hydro One in the selection, acquisition and implementation of ORMS.  Members of ExtenSys also participated by: 

  • Providing subject matter expertise on outage management systems during the selection and implementation process
  • Performing functional and structural testing of the system
  • Conducting risk mitigation analyses
  • Assisting in project coordination and planning
  • Creating a high level design of the future interface to Hydro One's Enterprise GIS (ArcGIS by ESRI)
