4. the Energy to Lead 4 Reducing carbon emissions to the environment

5. the Energy to Lead 5 5 Gas Distribution Model (GDM) > Objective Industry standard data model for natural gas distribution assets and operations > Benefits Reduce cost and complexity of GIS and supporting software integration Increase interoperability and reduce customization Facilitates electronic field data capture

6. the Energy to Lead 6 6 GDM Drivers > Why do we need a standard data model for the distribution industry? DIMP Shift towards electronic data and field data capture Models and software require lots of data Various different gas distribution data models

7. the Energy to Lead 7 7 Applications for GDM > Vendors Software standardization, ease of implementation, interoperability > Data Compilation Combine data across different operations Vertical integration of data across sectors >Industry Benchmarks and Data Collection Initiatives AGA, CGA, PPDC... >Future Advancements Smart phones Smart tags ASTM traceability standard

8. the Energy to Lead 8 8 Scope >Phase I Steering and Technical Committees GDM Scope Conceptual Model Logical Model Physical Model Model Testing – Oracle and SQL Server Documentation and Implementation Guide Release v. 1.0

9. the Energy to Lead 9 9 Stakeholder Committees > Steering Committee Autodesk, ESRI, GE Smallworld, GTI, National Grid, New Century Software, Sentinel USA, Structural Integrity, Southwest Gas > Technical Committee ESRI, GE Smallworld, GL Noble Denton, GTI, New Century Software, Sentinel USA, Opvantek, Southwest Gas

10. the Energy to Lead 10 the Energy to Lead 10 Model Highlights >Features Designed for Distribution and Transmission systems Supports stationed and un-stationed pipe (stationing is optional) Similar design concepts as PODS Oracle Spatial and SQL Server Spatial >Uses geometry data types

11. the Energy to Lead 11 the Energy to Lead 11 Key Concepts >Pressure System System of mains and related facilities fed by one or more regulators Each pressure system has an MAOP based on the MAOP of components within the pressure system Foreign key reference used instead of information on individual pipe and component records

12. the Energy to Lead 12 the Energy to Lead 12 Key Concepts >Linear Referencing and PODS Compatibility Distribution, transmission, and re-classifications Vertical integration Linear referencing but stationing is supported Supports Line, Route, and Series tables Adds EventRangeIndex table that eliminates the need for Event and EventRange tables in PODS Maintained outside of the user environment and managed by application software

13. the Energy to Lead 13 the Energy to Lead 13 Key Concepts >Regulators and Regulator Stations Various levels of detail Single point with inlet/outlet pressure More detailed information regarding internal piping >Service Points and Meters Link to meter is the CIS Foreign key used to link meter to DeliveryPoint >History Tracking Non in-line history approach Optional companion tables

14. the Energy to Lead 14 the Energy to Lead 14 >Table Categories Gas Pipe, Meta Data, Gas Systems, Tracer Wire Pipeline Centerline, Casings, Crossings Inspection and Maintenance Valves and Fittings, Metering, Receipt Points, Regulators Conditioning equipment, Cathodic Protection Class, Markers and Signs, Stations and Vaults Location and GPS Leak and Incident Reports Gas Distribution Model

17. the Energy to Lead 17 the Energy to Lead 17 Status >Logical and physical model complete >Testing physical model in Oracle Spatial and SQL Server Using basic test data set – primarily core tables Sample queries >Developing an Implementation Guide >Soliciting operator participants for pilot implementations >Soliciting commercializers

18. the Energy to Lead 18 the Energy to Lead 18 Next Steps > Complete testing > Finish documentation > Pilot projects with 1-2 operators > Marketing and advertising > Commercialization
