2 LADWP quick facts  Service territory 464 square miles  1.4 million electric meters  680,000 water meters  Peak capacity 7000 MW  Peak load 6165 MW  Water 2006/ million HCF

3 AMI technology criteria  Cost justifiable  Reliable billing data with multiple redundancy  Cover both water and power  Multi-purpose communications network  Flexibility to upgrade to fixed network solution

4 LADWP types of AMI  Radio Frequency (RF)  Walk by  Drive by  Fixed network  Wireless  Paging  GPRS  Modem

5 AMI current status  46,000 automatic energy meters  Residential meters (RF meters) – 25,000  Small commercial demand meters (RF meters) – 14,000  Large commercial wireless meters (A meters) – 7,200  300 automatic water meters

6 RF meter replacement program  45,000 small electric commercial customers without demand meters  20,000 safety and access related electric residential services  6,000 water meters in conjunction with the large water meter replacement program  All new residential and small commercial installations - Approximately 30,000 each water and power meters per year

7 Wireless replacement program  45,000 small electric commercial customers without demand meters  900 solar net meters  All new installations for large commercial customers

8 Hybrid solution Dynamic and flexible  Use drive-by for the majority of water & electric residential and small commercial customers, can be upgraded to fixed network as business needs change  Use wireless communication technology for dormitories and high turnover apartments with two-way communication for connect/disconnect, pre-pay and other broadband services  Use wireless communication with load interval data for large commercial and industrial customers.

9 Technology Challenges Prior to the installation of SmartMeter System  Recorders placed on 2,000 meters throughout the system to capture fifteen minutes LP  Data was manually retrieved once a month  Each recorder was visited and read by a meter reading personnel  Data was manually up loaded to the LADWP legacy system

10  Manual  Handhelds  Drive-by  Modem  Wireless, BPL, Fiber  Satellite AMI Technologies: Water Meter

11 Wireless System Strengths  Installation  Under the glass integrated WAN  No additional wiring for power  No phone line installation  Ideal for rapid deployment  Public Network  No build out  No maintenance  Excellent for disperse deployments  High in-building penetration  Can deploy in a strategic order by importance

12 Seamless Integration  Down Stream Processing: ALL of SmartSynch’s Customers use Itron Software interfaced directly with TMS  Itron Enterprise Edition  MV-90  MV-Web  Support for HHF, Native MV-90 and FIG exports

14 AMI Benefits Collections Field Work Management Safety Load Forecasting Metering Demand Management Outage & Restoration Tariff & Regulatory Asset Management Billing & Customer Care System Control Special Billing 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 OPPORTUNITIES 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
