6 SIGNIFICANT EVENTS LEADING TO ADVANCED METERING INITIATIVE IN TEXAS 1999: Public Utility Regulatory Act of Texas Senate Bill 7 (SB7) is Passed 2002: TX Deregulated Electric Market Goes Live on January 1st 2005: US Energy Policy Act - encourages time-based pricing and demand response 2005: TX House Bill 2129 is passed required the PUCT to plan for AMI in Texas 2007: PUCT Substantive Rule Advanced Metering rule provided the foundation for implementation activities involving: Automated Or Remote Meter Reading, Disconnect / Reconnect Time stamped Meter Data for Wholesale Market Settlement Near Real-Time Access To Customer Usage Data By Customer Or Customer s REP Meter Price Signal Updates Access to 15-minute Data by Customers, REP s, etc. On-Meter Storage Of Meter Data Home Area Network (HAN) Support Future Technology Advancement Support Access to Meter Information by ERCOT for Wholesale Market Settlement 6

7 ADVANCED METERING IMPLEMENTATION TEAMS (AMIT) Late 2007: PUCT Initiated Project #34610 to address changes in retail and wholesale markets as a result of advanced metering. Plan for settlement, Customer web portals, security, the Home Area Network, etc. Workshops all of 2008 and Security 2. Access to data 3. Web Portal 4. Standardization of Functionality 5. Home Area Network (HAN) 6. Retail Transactions 7. Settlement 8. Customer Education 9. Long Term Settlement 7
