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

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

AMI Program: OPPORTUNITIESOPPORTUNITIES

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
