Smart Grid Overview and Job Creation
Discussion Topics• Sempra/SDG&E Overview• Key Learning Points• Current Projects: Project Overviews & Job Creation
– Smart Meter: SDG&E’s AMI Program– OMS/DMS– CBM– Microgrid
• Potential Projects– Secure End-to-End Smart Grid Demonstration– GridComm
SDG&E Overview• Service area 4,100
square miles, covering two counties, 25 cities
• Owns 1,835 miles of electric transmission lines and 21,601 miles of electric distribution lines
• Operates two compressor stations, 166 miles of natural gas transmission pipelines, 8,100 miles of distribution pipelines and 6,197 miles of service lines
• 4,500 employees
Key Learning Points• Jobs need to span traditional silos:
– Customer– Distribution– Transmission– Information Technology– Internal and External Education, Training and Communication
• Like any change, preparing for a culture that embraces technology takes time– Prepare the foundation early
• 143% versus 35% ROI based on effectiveness of organization change mgmt (OCM), source: McKinsey– This translates to lower rates– Job creation means that jobs change
Current Projects
• Project Overviews
• Job Creation
Smart Meter
SDG&E Smart Meter Goals
• Replace 1.4 million electric meters
• Retrofit 900,000 gas meters
• Enhance customer service and improve utility operations
• Provide foundation for smart grid, smart premise, smart transportation
• Recognize this is not a typical utility infrastructure project
Business Case Overview$572MM Capital/O&M approved April 2007• Install 1.4 million smart/AMI electric meters for all
customers– Solid-state electric meter technology with ZigBee chip
• 2-way communications• 4 channels
– Electric interval data reads• Residential hourly, C&I 15 mins.
– Remote disconnect/connect integrated within 200 amp meter• Programmable load limiting switch
– On demand reads, demand reset• Adding module to existing 900,000 gas meters
– Daily gas reads
Business Case Overview cont.
– Next-day data for customers online/phone– Home area network (HAN)
• Local connectivity to remote devices, load control technology • Case includes 57K programmable communicating thermostats
(PCTs) for Small/Medium C&I – 55% Operational benefits, 45% Demand Response– Support price responsive tariffs (TOU, CPP, PTR, etc.)– Information systems, integration with legacy systems – Firmware downloadable to the meter– Remote device configuration/firmware & feature updates– Tamper/theft– Voltage– Outage/restoration– Security
Vendor and technology neutral as possible

Condition Based Maintenance(CBM)
Benefits of CBM
• Objectives– Extend the useful life and make greater utilization of
transmission and distribution substation assets
– Use technology to measure the performance and condition of equipment to make better maintenance decisions
• Benefits– Improve asset utilization– Improve efficiency of maintenance activities– More data – CBM captures data not seen today– More timely data

* SDG&E only
• Quicker identification & restoration of outages• Reduced customer impact
OMS/DMS Timeline
• Completed Requirements Phase
• Currently in Detailed design scheduled to be completed in November 2009
• Project implementation date is on target for 2011
MicroGrid
MicroGrid Goals & ScopeSDG&E’s MicroGrid project integrates a DOE component, focused on feeder applications and a CEC component, focused on customer-side applications
DOE Portion– $7.2M in DOE funds contribution towards $12M total project cost over 3 years – Goal to achieve >15% reduction in feeder peak load and improve system reliability– Perform cost/benefit analysis for full scale deployment – Involves Integration of 5 technologies:
1. DER and VAr 2. Feeder Automation System Technologies (FAST)3. Advanced Energy Storage (AES)4. OMS/DMS system5. Price Driven Load Mgmt (PDLM)
CEC Portion– Entirely CEC Funded ($2.8M)– Sustainable Communities MicroGrid project focused on interoperability, AMI and customer DER– Schedule to mesh with larger DOE proj. – Involves Integration of customer based technologies:
1. Remote Controlled Demand Response Devices (e.g. Thermostats)2. Solar panels3. Battery storage4. Plug-in Hybrid Electric Vehicles (PHEV’s)5. Grid-friendly appliances
MicroGrid Project
MicroGrid Selected Project Site
Goal to island an entire substationwith peak load of over 10 MW
Key Characteristics:
Strengths:• No residences nearby, plenty of land• More Existing Solar Customers• Large Reliability Improvements
Possible• Possibility of ‘Islanding’ Entire
Community
Challenges:• Remote Area• Challenging Communications
Environment• New Fencing Required• Requires Accelerating schedule for
Condition Based Maintenance and AMI Deployment
