Today’s Topic – Grid Modernization
■ The Path we are on Electrically connected GIS
Automatic model export
Electrically validated switching plans
Optimized feeder configurations
Wide deployment of SCADA
“Life-Story” or conditional based asset management
Efficient deployment of field resources and capital
“Big Data”

What does this mean?
Let’s look at the old way of doing things
17
Faulted Circuit (10 years ago)
■ Fuse Blow
■ Calls from customers
■ Line truck dispatched to mid-circuit area
■ Internal memo / email outage notification
■ Patrol / check fault indicators to locate damage
■ Switching to Isolate
■ Restoration / Repair, backup feeder maybe overloaded
■ Calls are still coming in
■ Customer result: Lots out ~45min, a handful for repair (1-2 hrs).
■ Paper record of repair -> drawing backlog
■ Queue for outage report
18
Faulted Circuit (potential future) ■ Fuse Blow
■ AMI last gasp reports all outaged customers to OMS
■ OMS issues alert to system operator and internal pool of recipients
■ DA and RFI report passage of fault to DMS and operators through
SCADA
■ DMS pinpoints fault location to correct circuit branch, and within
200m
■ DMS possibly uses DA devices for FLISR through SCADA,
restoring 50-75% of circuit in less than 120 min.
■ DMS issues recommended switching plan to further isolate
damaged equipment
■ Control sends trouble directly to site to confirm damage & begin
local isolation
■ Calls are starting to come in
■ DMS suggests feeder re-organization to balance load on remaining
feeders, executed through SCADA remote switching by operators
■ Field Repair proceeds
■ DMS suggests optimal switching for feeder return to normal
■ Customer result: Some out for <60sec, some out for ~20min, and a
some out for repair (1-2 hrs).
■ Outage report, statistics, and logging all automatically captured.
Fault scenario can be replayed for analysis, training, or audit.
■ Stressed components are captured by asset management system
integrated with ADMS, and follow action can be taken to mitigate
future potential outages
19
But wait….
■ Technology isn’t everything.
You have to build your organization to succeed.
Technology changes go hand-in-hand with business and organization changes.
20
Business Transformation
■ You need operational
excellence. Silos don’t work
Define and follow our
processes
Skills and training
Fully utilize the benefits of
these technologies
■ You need different skills
than 10 years ago. Ex: GIS modelers
More than Civil / Electrical
Engineers
SCADA, Comms, and analyst
skills can be a big gap.
21
Transformations at EPCOR
■ Some Challenges Knowledge transfer
Training: new staff and
transfer of existing staff
Identifying and acquiring new
skills
Integrating processes and
technologies for maximum
benefit
Keeping everything else rolling
■ Many business units
have been rebuilt
■ New leadership focused
on Operations
■ Skills assessment
■ Procedures
