1. PCI Webinar on Using PCI Energy Accounting System to Validate Meter Data March 5, 2015

2. Webinar Agenda  Overview on PCI Energy Accounting System  Demo of PCI Energy Accounting System  Benefits of PCI Energy Accounting System – User feedback  Next Steps

3. The PCI Energy Accounting (EA) System is designed to:  Track, calculate, and verify meter data  Validate actual energy flows and perform Real-Time check- outs with counterparties. Manage Meter data for generators Meter data for loads Meter data for Pseudo Tied Gen & Load Interchange schedules between BAs Inadvertent Energy Losses 3 Capabilities of PCI Energy Accounting Solution

4. Key Functions of PCI Energy Accounting  Meter-Data Management Meter Data Quality (validation, editing, estimation) Data Submission to ISO Reporting  Schedule / Reservation Management Review, correct, validate schedules and Calculations: Loads, Inadvertent, Transmission Usage  Check out (intraday, day after, monthly) Scheduled Interchange Actual Interchange Inadvertent  Calculations Load, Hierarchical, JOU, Aggregate, NAI, NSI Losses, Transmission usage  Other Functions Weather, Emissions, and Fuel Tracking Data Warehouse to support billing and reporting 4 Small error of 10-20 MWh per hour can create settlement impact of 2-4 M$/year

5.  Companies can define all their meter locations (Load, Gen, Tie, ISO Node, Interchange, Inadvertent, Miscellaneous)  Multiple data sources for each meter (MV90, Accumulator, AAV, External, etc.) with primary and backup values that can be tracked and compared.  Meters can be “real” or “virtual” (calculated) with hundreds of attributes to define their characteristics  Meter configurations can vary with time Meter Configuration

6. Provide Powerful Dashboard to Validate Meter Data and Identify Potential Meter Data Errors  Multiple meters can be seen at once (Meter Groups) with vertical and horizontal type screens and Daily to Hourly drill down.  Multiple sources can be seen and compared on the display  Colors for meter quality flags and validation errors  Ability to enter Comments / Reasons for changes  All meter data revisions are tracked by date and user.

7. Data Validation Engine  PCI provides a built-in validation engine, with user-configurable rules to check and validate meter data consistency using multiple meter data sources  Support standard rules, and provide capability to create new rules  Provide Auto-validation Exception report

8. Data Auditing  PCI provides dashboards to view all data changes (when, who, notes)

9. Meter-Data Submission to ISO  Provide Screens to review and submit meter data to ISO  Support Automated submissions, with counterparty file sharing (FTP)  Users can see changes from last submissions for NAI and Meter Data  Provide Readiness/Verification and Status screens.

10. Graphing Capabilities  Multiple Meters and Sources can be graphed for comparison

11. Managing & Validating Tie Schedules  Review and checkout schedules with neighbors and counterparties.  Support Drill-in capability from check out to schedule data  Use tie schedules to calculate loads, NSI, NAI, Transmission usage

12. PCI Checkout Screens  Provide screen to display Net Actual Interchange, with daily, on/off peak, and Tie-by- Tie display  Support Drill-down capability to view andmodify underlying data  Provide Journal/Log screen to track checkout activity (when, who, notes)

13.  Visually view calculation results and all their inputs using Calculation Tree  Calculations propagate both value and quality code Calculations Review

14. Custom Calculations  PCI supports customized calculations. There is no limit on the number and complexity of calculations.  Calculated values can be stored in virtual meters.  Calculations can be manually initiated, scheduled, or event driven.

15. Reports  Standard hourly, daily, monthly reports,  Create ad-hoc reports, and  Create ad-hoc datasets for export or direct data access to other systems.  PCI has a comprehensive API to allow external access to data or data exports can be utilized.  User have a report wizard available to enable quick ad hoc reporting.

16. Provide Configurable and Extensible Platform The PCI solution is designed to handle: o Specialized meter configurations, calculations and data integration o Customizable screens (Main Dashboard) o Overall screen layout, naming and organization o Integration into and out of the application.

17. With the PCI Energy Accounting Solution, your company can validate meter data and perform check-outs with counterparties. The PCI solution integrates with Scheduling software to capture schedules Metering systems to retrieve meter data SCADA/EMS/GMS to retrieve Real-Time meter data ISO/RTOs for reporting meter data as a Meter Data Management Agent (MDMA) Weather providers to obtain and store weather data 17 PCI provides a Fully Integrated Solution for Energy Accounting

18.  Fuel Management Tracking and Calculating Fuel Inventories Tracking and Calculating Fuel Costs Tracking Budgeted Fuel Costs Comparison of Actual to Budget Inventories/Cost  Weather Data Management Storing Weather Forecast Data Downloading and Storing Weather Data from The National Weather Service Calculating Values such as Wind Forecasts or Load Forecasts using Weather Data. Other functions

19. What Users Like Most about PCI Energy Accounting System User Configurability –Addition, Deletion, Modifications to Calculations, CP Node components are easily configurable by the user. –Eliminates the need for software changes to incorporate updates to meters and calculations. Less time intensive Minimizes dependencies on different organizations –Changes can be made in seconds. –Data is easily viewable through drop down/expandable folders which provides simplistic means for data viewability.

20. Benefits of PCI Energy Accounting Advantages –Quick and easy setup to add users –Fast display call up –Ability to re-import data to correct data if meter data setup changes –Ability to import multiple sources of data including customer data –Ability to export data - Very fast –Pre-Validation Capabilities a must feature for managing large amount of meter data on a daily basis.
