Distribution:

123,000 km of distribution lines,

1.8M poles, 1.3M customers,

640,000 sq km service territory

(twice the size of Texas)acquired 90 utilities since 2000

(still about 90 utilities left)

Who are we

Transmission:28,600 (circuit -

km) interconnected

85,000 towers, 4000 km fibre

Peak demand: 27,005 MWEnergy transmitted: 157 TWh

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

Automobile: power steering Electrical: cutouts and fuses

Level 2: Intelligent functional assist or protection Automobile: ABS brakes

Electrical: automated reclosers

Level 3: Full intelligent operation with human assistance

Digital Cameras Electrical: SCADA

Level 4: Full intelligent operation w/o human intervention

ADS RFP is looking for: DMS Intelligent Devices to support DMS

Based on 4 Business Objectives:

DG Integration Distribution Reliability / Operations Improvement

Outage Restoration Optimization

Distribution Network Asset Planning and Tools

Advanced Distribution Solution

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
