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
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
LADWP types of AMI • Radio Frequency (RF) • Walk by • Drive by • Fixed network • Wireless • Paging • GPRS • Modem
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
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
Wireless replacement program • 45,000 small electric commercial customers without demand meters • 900 solar net meters • All new installations for large commercial customers
Hybrid solutionDynamic 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.
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
AMI Technologies: • Manual • Handhelds • Drive-by • Modem • Wireless, BPL, Fiber • Satellite Water Meter Water Meter Water Meter
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
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

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
Load Forecasting and Research • Forecasting • System Growth • Load Research • Class Profiles: • Residential • Small C&I • Medium C&I • Large C&I • System Load Scaling
Web Access Energy Load Monitoring Solar Generation Profile
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
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
