Ontario Ministry of Energy
Direction
Create an energy conservation culture across Ontario and help consumers
better manage their electricity use
More efficient use of Ontarios existing supply
Reduce reliance on external generation resources
Need to replace 80% of generation over next 20 years (~$70B)
Install 800,000 smart meters in Ontario by Dec. 2007
convert 100% to
smart meters by 2010

Distributed Generation Integration
Significant amount of new distributed
generation (DG) being planned on HydroOne distribution system as a result of theOntario Green Energy Act
Integrated system level view of Protectionand Control is required:
Remote integration, monitoring andcontrol
Automation and predictive modeling
DS monitoring
Automated generation rejection
DG protection
Dynamic controls
Interoperability

Distribution System Reliability and
Ops
The Dx system will be automated to varyingdegrees to provide for real-time monitoringand control, automatic restoration andoptimized operations to reduce overall utility
costs and improve customer satisfaction:
Real-time monitoring and control of TS,DS, RS, Line regulators, In-line Reclosers,Remote Control Switches, Capacitors,fault indicators, instrument transformersfor line segment loading
Interoperability amongst all devices
Improved SAIDI/CAIDI/SAIFI
Visual realization (wide areavisualization of network , installation ofvideo equipment)

Outage Restoration
Customer outage duration will be minimizedby leveraging scenario 2 with quicker moreefficient fault restoration by enhancing fieldforce mobilization:
Integration of key enterprise systems(SCADA, GIS, AMI, CIS, WFM, OMS,Customer Portal) to streamline businessprocesses
AMI and feeder device data garnered overwireless communication network
Field force location known by GPS withlone worker personal devices for safety
Accomplishment reporting, asset andmaterial updates in real-time
Customer notification of outage status

Dx Network Asset Planning and
Tools
Automate process of planning (networkmodeling and design) to provide superioranalytics that feed distribution capital andmaintenance programs
Dx feeder connectivity model availablein spatial representation (GIS)
Combine with station and feederelectrical operational data store
Single system of record
Archival data from real timemonitoring and control of TS, DS, RS,Line Regulators, In-line reclosers,
switches, etc. Meet NERC requirements
