1 Migration To MDM/R Production Mode P.D Ferguson, P.Eng President Newmarket Tay Power Distribution Ltd.

2 The Utility Two part service area Town of Newmarket Part of Township of Tay Newmarket Population density of 20 per hectare 35 km north of Toronto 27,000 customers Tay Population density of less than 5 per hectare Southeast shoreline of Georgian Bay 4,000 customers

3 Present SM Status 28,000 meters deployed Sensus Icon 100% of residential class Mandatory Time-of-Use Rates Declared November, 2007 Migrate residential class 1 st, then small general service (<50 kw demand) Migration by billing section

4 Present TOU Status Time of Use Billing Customers billed using Ontario Energy Board approved Time of Use rates. Detailed time of use consumption report with bill Web presentment Customer Migration 10% of residential class now on TOU 20% by end of March, % by year end

5 Data Management Meter Deployment and Initial TOU Billing Contract 3 rd party to provide initial MDR Provide meter data reporting verification and statistics during deployment TOU pricing pilots pre mandatory TOU Provincial MDM/R Integration Began working with Independent Electricity System Operator (IESO) in March, 2007 Production Pilot mode October, 2007

6 Meter Deployment The Challenges Meter changes are meter changes, BUT Are the meters operating to specification? Managing the AMI, CIS and MDM/R Network Network Component Testing and Integration The IT part Business Process Review The People part

7 Smart Meter Reality You re installing AMI You ll end up with a telecomm network Every meter is like a cell phone that wants to call home hourly Your utility will begin to understand the meaning of Dropped Calls

8 The Network Before Smart Meters Meters Meter Activity Meter Work Orders Meter Readings CIS Meter Inventory Premise management Account management

9 The Network With Smart Meters Meter Activity Smart Meters Meter Work Orders CIS Meter Readings AMI MDM/R Premise and account management

10 Managing the Network Conventional meters If removed or power lost, they stopped If re-installed or power restored, they started and no one noticed New installs, removals, premise changes Only the CIS noticed Rate changes Simple pro-rate of consumption and cost

11 Smart Meters Managing the Network Report all activity to AMI and MDM/R Power out Power restore Tamper Internal diagnostics New installs, removals, premise changes Noticed by CIS, AMI and MDM/R Rate Changes TOU block rate changes TOU time period changes Fixed/TOU rate changes

12 The New Network AMI, MDM/R, CIS are discrete components Pre Smart Meters, the CIS integrated all meter, account and reading data With Smart meters, there is a need to create a contiguous system Any discontinuities in databases will create exceptions

13 Network Components Meter Deployment and AMI Meter Performance Management

14 Network Integration To Synch....or Sink The MDM/R synchronization file is the backbone of the Network

15 MDM/R in Production Pilot Integration Status Responding to all data deposits and withdrawals Submitting daily synchronization files AMI Daily meter and premise activity reported at end of each day Updated daily using MDM/R synch file CIS Generating daily synch file Meter activity reporting by Work Force Management System

16 Meter Activity Meter installs Meter exchanges Business Processes Previously paper work orders Now using WFM to update CIS and generate Synch file Meter activity reported same day to MDM/R and AMI

17 Billing Processes Business Processes Presently, walk-up meter read schedule drives billing schedule. Every day is a reading day, a billing day and a due day Billed consumption can be for a calendar month, half of one month and half the next, or anywhere in between Creates need to pro-rate rate changes Migrating to calendar month consumption, independent of billing date Eliminate pro-rate

18 MDM/R Activity Detail examination of AMI data input and billing quantity output Parallel of utility legacy and new smart meter systems Using 250 Pilot accounts Accounts have been billed on TOU for about 14 months, hourly data collected for over 2 years Interval by interval comparison of AMI, contract MDR and IESO MDM/R data Verification of data framing, VEE and synch file functions

19 Data framing: Period consumption TOU Buckets Hourly interval VEE Verify rule sets Consistency MDM/R Parallel Tests Anomalies analyzed to determine cause Synch File Meter activity exceptions

20 Parallel Testing: Going Forward December, January, February data being tested Anticipate March cut-over Accelerated TOU implementation Beginning in March Enhance customer interfaces based on feedback Website tools In bill and on bill presentments Customer behavioural analysis
