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 2006/2007 - 275 million HCF
3
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
4 LADWP types of AMI Radio Frequency (RF) Walk by Drive by Fixed network Wireless Paging GPRS Modem
5
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
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
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
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.

10 Manual Handhelds Drive-by Modem Wireless, BPL, Fiber Satellite AMI Technologies: Water Meter
11
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
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
13
13 Meter SSI TMS Servers Two-way Wireless Paging (6000 AMR Meters) Telephone Modem Itron Meter Reading System, Datacap Meter Reader- manual retrieval (1500 Recorders) Phone Lines (50 Existing lines) MV-90 Server and Client Workstations CIS Billing System MV-Web Servers Daily Updates for 6000 Meters Before 12 pm. Daily Updates for 50 Modem Meters Before 5 am. Monthly Updates for 1500 Other Recorders.) Energy Load Management System (Daily Updates for 50 Paying customers before 5am All Special Billing Accounts & Reports Outage Management System (6000 Meter Points for Outage Detection) Daily Monthly Rates Analysis/Billing System (Support 20,000 large and medium accounts that provide 50% of Power revenue) LADWP AMI System

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
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
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
17 Outage & Restoration
18
18 Web Access Energy Load Monitoring Solar Generation Profile
19
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
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
