Province of Ontario Smart Meter Initiative Highlights Drivers  Demand increase outpacing supply  Coal-fired generation closure commitments by 2007 (25% of electrical generation)  Problems with existing nuclear plants  Transmission system constraints  Lack of investment in new generating plants Plan  Implement smart meters across Ontario for (virtually) all consumer segments (accompanied by rate re-structuring) Rationale  Providing consumers with time-based energy consumption information and time- based rates will motivate them to alter their consumption behavior using less energy at peak times of day.

Discussion Topics Smart Metering Initiative Obstacles and Issues  Data collection, validation and rebuilding  Storage, process interfaces  Billing, consumer presentment, reporting  Implementation timing, multiple vendors Smart Meter Data Standard Benefits  Risk mitigation  Integration efficiencies  Better cost control or reduction Smart Meter Data Standards can mitigate risk, provide relief from implementation timelines, and lower costs associated with a Smart Meter Initiative

5. Obstacles and Issues

6. Confidential to The SPi Group Inc. For Internal Use Only. Copyright © The SPi Group Inc. 2005. All Rights Reserved. Smart Meter Data Collection  Communications capacity, timing and logistics  All formats of billing determinants (TOU, interval)  Data collection hybrids in terms of technology, features, data  Manage meter change-out process (re-verification, failures) Issue: Risk of implementation delays due to testing and certification Risk of proprietary technology commitment (Cost) Local Distribution Company Vendor “B” native Smart Meter Data Vendor “A” native Smart Meter Data Obstacles and Issues

7. Confidential to The SPi Group Inc. For Internal Use Only. Copyright © The SPi Group Inc. 2005. All Rights Reserved. Validation, Editing and Rebuilding Editing and Rebuilding  Residential vs. C&I business rules  Automated vs. manual intervention  Access to history for rebuilding  Data not processed by 8:00 a.m.  Time limit to process / update MDR  Audit trail For Presentment Purposes  Portraying data correctly  Updating already presented data Validation  Residential vs. C&I business rules  Dependent on data available  Simple limits for “outliers”  Cumulative to interval/TOU billing determinant comparison  More complex “missing data” rules Vendor “A” native Smart Meter Data Validation Editing and Rebuilding MDR Smart Meter Data Repository Vendor “B” native Smart Meter Data Issue: Risk of implementation delays due to testing and certification Risk of proprietary service commitment (Cost) Obstacles and Issues

8. Confidential to The SPi Group Inc. For Internal Use Only. Copyright © The SPi Group Inc. 2005. All Rights Reserved. Smart Meter Data Storage  Volumes (4.3 Million meters)  > 46.8 B interval readings per year  > 1.65 TB of raw interval transaction data per year alone!  Types of metered data  Interval (15 and 60 minutes)  TOU cumulative energy (multi-register)  Straight energy (single register)  Vendor formats  Types of non-metered data  Audit  Tamper  Power Quality  Other billing determinant data “Non smart” meters during implementation Wholesale metering data Consolidated meter data  Maintain consumer – meter – service address relationship  Consumer information store  Relationship consumer – meter – service address – data access Issue: Cost of non-homogeneous data management Wholesale Metering Systems Vendor “A” native Smart Meter Data MDR Smart Meter Data Repository Vendor “B” native Smart Meter Data Non-Smart Metering Systems Obstacles and Issues

12. Confidential to The SPi Group Inc. For Internal Use Only. Copyright © The SPi Group Inc. 2005. All Rights Reserved. Reporting  Audit reporting  Changes to Smart Meter data  Editing and rebuilding audit  Tracking of rules applied, when by whom  Multiple information sources  Ad-Hoc reporting  Standard tools  Open access  Operations and Exception reporting Obstacles and Issues Successful initialization of modules installed in the field Discrepancies in modules and CIS links Successful capture of meter reads – benchmark of 95% Meter read reports Module alarms and status indicators Suspected tamper and trend reports Communication link monitoring, and Status indicators for regional collectors Validation results automated (e-file/email) Network or communication link failures Power failures Memory capacity issues or meter failures TOU time or communication module reprogram failures Issue: Risk of unknown reporting requirements

13. Smart Meter Data Standards and Network Solution

14. Confidential to The SPi Group Inc. For Internal Use Only. Copyright © The SPi Group Inc. 2005. All Rights Reserved. Smart Meter Data Standards Functionality 1. Content  Structure and format of data passed between systems. 2. Storage  Minimum requirements for amount of data to be stored and the corresponding retention periods. 3. Connectivity and Delivery  Delivery methods required to transport data between systems, including how systems locate and connect to each other. Characteristics of Functionality 1. Security  Storage and delivery must be secure, and systems and parties must be authenticated before data passes. 2. Certification Capabilities  Minimum requirements to demonstrate regulatory compliance. 3. Audit Capabilities  Ability to audit delivery and content of data, and non-repudiation of parties, especially when using independent third parties. 4. Reliability  Minimum requirements to ensure availability of systems and methods of service-interruption recovery. Network Solution
