Drivers – Growing Need for Flexibility starting in 2015
• Significant ramping will be required in both AM and PM to accommodate renewable production
• Governor has a plan for 12 GW of DER (> 1 GW for SDG&E)
• Coordinated operation of various DER can help mitigate ramping requirements for baseload generation

Drivers – Renewable Variability/Intermittancy
• Advanced forecasting capabilities for dispatching DER
• Distributed controls for smoothing spikes
Drivers – Growth in Commercial/Residential Solar Generation
• Net Energy Metering (NEM) production “hides” load
• Ability to create voltage issues and excess equipment operations
Drivers – Fast Forward to 2020

Historical growth is significantly higher than the 18% shown.
• Rule 21 is being revisited to consider requiring “smart” inverter functionality
• Smart Inverters have the ability to respond to control signals from the utility
~ 12% of forecasted 5000 MW peak load
• More than 25,000 rooftop solar installations in San Diego, highest per capita rate in country
• Produce more than 184 MW of clean electricity 8
Drivers – San Diego’s Solar Rooftops

Microgrids:• Manage DER
• Manage voltage and power quality at local level
Dynamic Grid Tools – Microgrids
• Support the integration of renewable resources
• Improve reliability and power quality• Support emergency operations• Ability to “ride through” outages• Optimize energy usage• Enable participation in new markets for
demand response and ancillary services

Dynamic Grid Tools – Microgrid Opportunities
Replace existing OMS and install new DMS system with integrations to GIS, CIS, AMI, SCADA, Crew Dispatching …
WENT LIVE SEPTEMBER 29, 2012!
► Paperwork► Manual processes► Software systems are not fully
integrated► Most Unplanned outages are
reported by customers
► Near real time data► Automated process► Integration with many systems► Faster outage restoration times► Improved outage

Present FuturePAST NOW
Dynamic Grid Tools – Outage / Distribution Management System (OMS/DMS)
Utilize advanced technologies to integrate and manage distributed resources within the Smart Grid
Budget: $8.0M DOE and $2.8M CEC plus matching funds from SDG&E and partners
Benefits: Integrate and leverage various generation and storage configurationsReduce the peak load of feeders and enhance system reliabilityEnable customers to become more active participants in managing their energy use
