5. What Are We Doing to Promote Smart Grid? • Projects for Smart Substations and Transmission Management • Projects for Smart Distribution • Projects that Integrate DG

6. Synchronized Sampling and Phasor Development CCET Participants Description Working with DoE, EPRI, and ERCOT the CCET companies and university researchers are demonstrating these technologies at substations and within the ERCOT system to allow better operator control, blackout prevention and service restoration, maintain reliability standards, and integrate wind energy. The technology provides much improved operator situational awareness over existing SCADA systems. RTDMS Deployment and Phasor Roadmap Development 7

7. Demand Response Pilot CCET Participants Description CCET is leading a Demand Response program in Dallas and Houston during the summer and fall of 2008. The pilot takes advantage of early deployment of advanced metering/AMI systems in Houston & Dallas to test DR in restructured market and consumer acceptance of various control strategies (thermostats, water heaters and pool pumps) by Direct Energy, Reliant and TXU Energy.

9. DG Project Coming Soon • Involves new planned solar community • Potentially involves most of our members • Stay tuned

10. What Are We Doing About Interoperability? • Not nearly enough, but we’re working on it

11. CIM Standards Task Force CCET Participants Description I. Developed an online data base of IEC/UCA Standards references and a collection of CIM models 2. Evaluated a proposed approach to begin CIM-like standards development for the application layer interface with the HAN 3. Promoting CIM for Distribution that supports CIM for Transmission adopted by ERCOT 4. Task Force to Participate in New Project Design 7

12. PUCT Tackling the Problem of Interoperability at the Meter/HAN Interface Description Texas PUC is working the process of defining the capacities required for enabling DR by TDSPs and solving the problem of capacity to support DR and assignment of responsibility among market participants and stakeholders PROJECT NO. 31418 RULEMAKING RELATED TO ADVANCED METERING Project 4. AMIT HAN Project: Task 125 1. List of Use Cases A1 – Load Control Message A2 – Price Signal Message A3 – Numerical and Text Message A4 – Ping the AMS Meter A5 – HAN Device requests AMS Meter data A6 –Messages sent from HAN Device CCET Member Individual Participation at PUCT Workshop 7

13. What Are We Doing About Interoperability? • We’re working on it because the policies of Advanced Meters/AMI and RPS requires a solution • The commitment to restructured market • Legislatively driven invitation to IOUs to invest in advanced meters and AMI • Legislatively driven RPS is focusing attention on wind integration • These large investments will drive attention to the interoperability challenge
