•Key points•The OMS/DMS initiative will identify the area and customers out of

service and enable faster restoration times

•The OMS/DMS initiative will enable enhanced monitoring of thedistribution system, resulting in controlling actions to mitigate voltage andpower flow problems

•The OMS/DMS initiative is a key enabler to future Smart Gridapplications

•Why is this so important?•The enhanced control of the distribution system results in increased

public safety, better response to adverse events and increased operatorsituational awareness

What is OMS/DMS?

Smart Substations

• Use technology (hardware/software) to assess the condition andperformance of substation transformers and breakers to makebetter maintenance decisions

• Technology: Sensors will provide diagnostic information to facilitate amore focused maintenance strategy

• Software will enable analysis of measured data•Maintenance is shifted from “Time-Based”to

an “As-Needed”basis

Energy Storage Perspective –Electric Vehicles

“This morning, we are announcing our partnership with Nissan to help bring one-hundredall-electric vehicles to San Diego. This regional partnership is aimed at assessing zeroemission mobility for the San Diego region, and the first step in delivering all the benefitsthat can come along with it a reality. In this partnership, SDG&E and SANDAG willcoordinate the deployment of electric vehicles throughout the region. SDG&E has enteredinto this agreement to lead the charge for the region, and assist others in incorporatingthese vehicles into their fleets and daily.”
