2. SCE Smart Grid Use Cases Southern California Edison developed extensive use cases We feel these should be brought to 4g’s attention These use cases and their requirements can be useful to 4g in developing the baseline and standard www.sce.com/usecases

3. Scope Some of the use cases apply directly to AMI, some are broader Smart Grid Cover all, as the broader context has implications for AMI

4. Different Classes of Response Fast - roundtrip within mSec over large dist. Automated Medium - (re)actions in 30 sec timeframes Operator involved, machine assisted Confidence/Corroboration of data needed Slow - actions within hours to days

5. Different Classes of Security High - affects grid stability (real time) Confidence/Corroboration of Data Medium - sensitive mid term data Sensitive data showing typical grid operation and exposing vulnerability Low/None - stored/post analyzed data

6. Use Case Categories Building and Customer Service Customer Interface Delivery Energy Procurement Field Services and System Recovery Installation and Maintenance PEV - PlugIn Electric Vehicles

7. Building and Customer Service Multiple Clients Read Demand and Energy Data Automatically from Customer Premises Remotely Limit Usage and/or Connect and Disconnect Customers Detect of Tampering or Theft at Customer Site Contract Meter Reading (or Meter Reading for other Utilities). Utility Side Collect consumption information from meter (available at multiple points from meter to the back office) Routine move-in, move-out, disconnect - lack of payment, connect - payment resumed, disconnect when load exceeds customer allowance Detect potential theft of services, tampering liability concerns Support of non-electric advanced meters (water, gas) on electric metering network

8. Customer Interface Customer Reduces Usage in Response to Pricing or Voluntary Load Reduction Events Customer Access to Recent Energy Usage and Cost at Their Site Customer Prepays for Electric Services External Clients Use the AMI to Interact with Devices at Customer Site Smart Appliance Use Energy Mgmnt. Sys. (EMS) or In-Home Display (IHD) Using Data for Targeted Mkting Campaigns Analyses Using Load Researchers Data

9. Customer Interface (cont’d.) Customer Side Responds to request for load reduction Evaluate energy spending and usage and make real time adjustments Prepay for their or others accounts Provides for third party control of energy consuming devices Installs, configures, registers and uses device Utility Side Sends request for load reduction Provides individual usage information Device responds to information from utility Offers programs to match customer usage scenarios/characteristics Analyzes a variety of load scenarios - individual, group, segment, etc. to generate statistics for many (customer and internal) uses

10. Delivery Distribution Operations Curtails Customer Load for Grid Management Distribution Engineering or Operations Optimize Network Based on Data Collected by the AMI System Customer Provides Distributed Generation Locating Outage Using AMI Data and Restores Service Automatic Reconfiguration of Power System for Reliability Distribution Operator Controlling Distribution System Distribution Planner Optimizing Asset Utilization Planners Performing Analytics Using Historical Data Utility Managing Utility-Owned Distributed Generation Field Worker Using Consolidated Mobile Solution (CMS) Using Technology to Enhance Outage Comm. Processes Utilizing Energy Storage to Balance Renewable Variability Auto Trigger of FACTS Devices Using Phasor Data to Maintain Sys. Stability Dissolved Gas Monitoring to Detect Emerging Failures of Transformer Banks C-RAS Sys. Monitors Grid System Status and Exerts Control to Maintain System Stability and Prevent Overloads Using Phasor Data for Grid Operation, Control and Analysis Optimizing Transmission Throughput Using Dynamic Ratings Using Monitoring Data for Condition-Based Maintenance Programs Using “Data Beyond SCADA” to Analyze System Faults

11. Delivery (cont’d.) Utility Side Request for future reductions (sometimes may be overridden by customer) General network optimization Integration of customer generated energy Improved service restoration and reliability Reduce manpower (CSR and crews) to service outages Improved grid management/reliability Provides DR (demand response) capability Distribution transformer management (load, deploy, maintain, replace, etc.) Asset inspection and planned/unplanned work assignments Improved communication to customer during outages Balancing/management of renewable with energy storage Maintain system stability following a destabilizing event Increased frequency of monitoring to optimize transformer utilization and take corrective action Fast centralized response to system stability to enable faster tripping, load shedding or system configuration changes Use post event system condition analysis capabilities to help prevent further/widespread events Using dynamic rating of transmission lines and transformers to optimize the power throughput Predict/determine transmission and distribution faults

12. Energy Procurement Real Time Operations Curtails or Limits Load for Economic Dispatch (ES&M) Utility Procures Energy and Settles Wholesale Transactions Using Data from the System Utility Side Support of demand response events Supply and demand for the Grid

13. Field Services and System Recovery AMI System Recovers After Outage, Communications or Equipment Failure Utility Side Systematic service recovery after single customer and system outages and equipment failures

14. Installation and Maintenance Utility Installs, Provisions, and Configures the AMI System Utility Manages End-to-End Lifecycle of the Meter System Utility Upgrades AMI to Address Future Requirements Utility Side Establishing AMI Systems Diagnose health of network and keep it healthy Provide future expansion of capabilities, features and services

15. PEV - Plug-In Electric Vehicles Provide Services to Plug-In Electric Vehicle (PEV) Customer Customer Connects Plug-in Electric Vehicle (PEV) to a Premises Energy Portal Customer Enrolls in a PEV Demand-Side Management Program Customer Side Enroll, register and setup comm. with utility Utility Side Repeatedly establishes communication with PEV’s Provide PEV charging status to customer Accurately bill PEV customer Offering/tracking off-peak charging incentives Provide demand response requests to PEV customers to control load Time of use, discrete or periodic/hourly pricing
