Plug-in Electric Vehicle ReadinessManaging the Electric Grid Doug Kim, Director – PEV Readiness August 6, 2010
Utility Management of Grid Impacts Forecasting & Assessment Engineering & Planning Response & Execution • Indicative information on vehicle volumes and clustering • Assumptions on charging behaviors • Detailed circuit modeling of incremental EV impacts • Feedback from actual adoption information • Incorporate EVs into current long lead-time work planning procedures • Adjust infrastructure replacement programs for EV expectations • Change design standards for new load expectations • Perform infrastructure inspection with each known EV • Streamline customer processes • Even out workload to avoid resource constraints & delays • Provide learnings to forecasts & engineering SCE is undertaking the necessary steps to ensure grid stability, but better information on EV adopters and acceptance of off-peak charging can significantly reduce costs
Evolution of Grid Impact Management Cumulative Plug-in Vehicles Forecast in SCE Territory (in thousands) 1 2 3 Local Distribution System Load Management Smart Grid • Insufficient volume for load control benefit realization • Awareness of TOU rates • Utility responds to transformer and sub-circuit issues • Emerging vehicle-grid communications enable smart charging • Customer education takes hold & behaviors shift • Emerging smart grid deployment enables advanced control programs • Customer “energy conscience” well developed Handraiser and purchase notification is key Off-peak charging behaviors create real benefit Interoperability needed for energy management
Stakeholder Collaboration a Necessity • Share handraiser information to inform planning process & improve long-lead time investments • Obtain early, address-level notification of PEV adopters through “data clearinghouse” • Increase customer awareness of time-of-use rates & encourage off-peak charging • Develop “smart charging” equipment and communication protocols to enable load management Customers Standards Organizations Car Manufacturers (OEM) PEV Ecosystem Charging Equipment Manufacturers State Government/ Agencies Equipment Installation Providers Local Government & Communities Charging Stations Operators Trade Associations/ NGOs Utilities Managing the electric grid reliability and cost is a long-term project that requires the cooperation of the entire EV ecosystem now
