Consumers EnergyGas and Electric Utility Operations
• 5th Largest Natural Gas LDC in the U.S. • Annual gas deliveries 250 bcf• 13,000 square miles of service area• 24,500 miles of T&D pipeline• 1.6 million gas customers• 120 City-Gates, 650 Regulator Stations• 1,000 Regulator Stands
• 10th Largest Investor-Owned Electric Company
• 25,000 square miles of service area
• 70,200 miles of T&D lines
• 1.7 million electric customers
All Gas Facility Data Migrated
Gas GIS Applications will use Single Repository for all gas facility data access

Gas Facility Initiatives Based on Single Data Repository
Non Core Application User Access
• Citrix Server Clients using the Company internal Intranet
– ArcMap, and Code Compliance Applications run on Citrix Server and results are displayed on their desktop
– No Software distribution to users machines– Home access using VPN technology– Far less Network Traffic
• ArcIms Clients using Company internal Intranet
– Hybrid approach using ArcIms and PDF files

System Planning and Emergency Dispatch
• All 455,000 gas main segments are used in GIS system planning model
• 1.6 Million Customer taps on gas main– Used in determining location of loads– Used in determining bypass size in outages– Used to build lists of customers without gas for light
ups in an emergency outage
System Planning
Stoner SynerGEE - Gas Load Analysis (Pressure Gradients)
Cathodic Protection (CorCon)
• All pipe, test leads, test stations, anodes, and rectifiers reside in the GIS database.– Information is available to Leak survey for code
compliance of unprotected pipe. – Test leads now reside in test stations which may
contain leads from multiple sectors– The application easily identifies using ArcMap
interface the pipe segments in a cathodic sector
CorCon Stand Alone
ArcMap and CorCon Application
Leak Survey (LeakCon)
• Leakcon application manages modules containing pipe and services to survey.– Business rules are maintained in the application to
determine when mains and services need to be surveyed
– Each pipe segment knows when it was surveyed last and when it should be surveyed next
– Each service knows when it was surveyed last and when it needs to be surveyed next
• Using the ArcMap interface the application easily identifies the pipe segments in a Module
ArcMap and LeakCon Application
Regulation Equipment Inspections (RegCon)
• All regulation facilities and equipment reside in GIS – Provides data about the inside of a regulator facility so
overpressure protection analysis can be done.– Each piece of equipment knows when it was inspected last
and when the next inspection needs to be done.• Using the ArcMap interface the application easily
identifies Regulator locations and the equipment inside the facility
ArcMap and Regcon Application
Decision Analysis Spreadsheets
• Civic Improvement Model– Water main,sewer replacements and paving
projects– Input from techs in each of the 9 areas into a very
detailed spreadsheet– ArcMap is now used to populate facility data
• Material Condition Model– Deteriorated pipe in each of 9 areas rated for
replacement – Leak survey results, leaks, leak repairs and
cathodic protection reads pulled from GIS
