How ENO Prioritizes Reliability Projects

Selection Process

Gather performance

data on all circuits

Circuit Review:•Operations•Customer Service•Engineering

Circuits ranked by performance &

customers affected

Circuits patrolled and work identified

Design jobs created Schedule projects by priority

Reliability Improvement Work Since 2008

Added two feeders Replaced cross arms Upgraded shield wires around the

substation Installed and replaced ground wires Installed fuses Installed fault indicators Replaced jumpers Inspected equipment (reclosers,

capacitors) Performed infrared inspections Trimmed trees

Week of July 26th: Determine corrective actions needed on feeders. Conduct pole inspections.

August 2010 – October 2010: Begin implementation of corrective actions. Conduct infrared inspections.

November 2010 – May 2011 Addition of feeder breakers to further sectionalize customers. Implementation of Automatic Load Transfer Scheme between

Almonaster and Tricou Substation to reduce customer impact. (Project approved and equipment on order)

What to Expect in Bywater Going Forward

What to Expect Going Forward (cont’d)ENO has and will continue to manage systemreliability:

Planned projects and activities should further improve reliability. Monitor reliability performance indicators (SAIFI, SAIDI). Routine inspections and repairs. Analysis of outages to identify repetitive problems. Continue to review technological advancements that reduce customer outages.

Communicate our progress Provide updates to Bywater Neighborhood Association. Provide update to Council in first quarter of 2011.
