14. AMI Benefits

15. Key Benefits • Have the flexibility to implement real-time pricing, TOU, critical peak pricing, and demand response tariffs for medium and large customers. • Produce dynamic load profiles of each rate class for more accurate cost-of-service studies as mandated by the CEC. • Support special contract accounts. • Design rates to collect revenue based upon actual cost of service rather than the average cost. • Enable creation of tariffs that are tailored to meet the needs of individual or segmented customer groups. • Provide information over Internet, including energy costs, actual individual’s usage, and typical usage by time of day. • Customers will have the ability to view detailed energy usage data

16. Load Forecasting and Research • Forecasting • System Growth • Load Research • Class Profiles: • Residential • Small C&I • Medium C&I • Large C&I • System Load Scaling

17. Outage & Restoration

18. Web Access Energy Load Monitoring Solar Generation Profile

19. AMI Program:OPPORTUNITIES • With the new Rate Analysis System, large commercial customers with wireless meters could be billed directly. • Customers could be offered calendar month billing and customized bills sent electronically. • Gas Company is installing 100k meters in the Los Angeles area and would like to coordinate with LADWP. • WIFI – Pilot Project to install WIFI meters in conjunction with the Mayor’s wireless plan for the City of Los Angeles • Net Metering – Install wireless meters for Solar Installations to provide customers billing with more detailed information such as energy generated, energy used and value of energy generated

20. Conclusion • LADWP realized operational and financial benefits by deploying the system and collecting interval data from existing smart meters • Value of real time interval data provides Opportunity for Demand response and load curtailment programs • Plans to expand deployment of Smart Meter programs to C&I customers
