  4. 4. IntroductionSouth Africa’s power system is constrained and will be for next few yearsEskom, together with stakeholders, have kept the lights on since 2008Most power stations are in their mid-life and require increased maintenanceStrategy of shifting maintenance outages can no longer be sustained.Significant maintenance is required to address backlogsInitiatives are in place to keep the lights on 4

  6. 6. The Threats and Opportunities created by ElectricVehicles
  7. 7. Impact of Electric VehiclesThreats Opportunities• EV’s will have a substantial • EV’s will result in additional impact on the demand for electricity usage and sales electricity • EV’s will provide electricity• Eskom does not have sufficient storage capacity which could generating capacity to meet the be a valuable resource existing demand for electricity • EV’s could bring investments• EV charging infrastructure will into the electricity sector put substantial additional load on already overloaded • Developments in EV’s could networks result in new technologies ie: batteries2011/11/09 7

  10. 10. Comparison of DSM & Demand Response Energy Efficiency: DSM • Permanent reduction in energy use • Invest in more efficient equipment • Eskom capex subsidy for equipment Load shifting / Peak Clipping: DSM • Reduce consumption during peak tariff hours • Invest in control systems • Eskom tariff price signal & capex subsidy Demand Response • Reduce consumption during peak system hours • Utilise storage, excess capacity, or process buffers • Eskom payment for temporary load reduction

  16. 16. Scenarios for Car Hire and Fleet Operators
  17. 17. Car Hire and Fleet Operators• Car Hire companies and fleet operators are ideally positioned to invest in EV infrastructure:- • Bulk charging facilities – Rapid charge and others • PV carports and parking facilities • Battery maintenance and spares • Sponsored charging facilities at various key facilities ie: hotels, shopping malls and points of interest
  18. 18. Extending smart grids to electric vehicles GE’s WattStation™ is a high-speed electric vehicle (EV) charger. Its smart grid-enabled technology could also help utility companies manage the impact of EVs on the local and regional grids. Decreases EV charging time from 12-18 hours to as little as 4-8 hours. Enables integration into the electrical distribution system, offering an end-to-end integrated EV infrastructure solution.http://www.ecomagination.com/technologies/wattstation/18

  20. 20. Nissan Leaf to help power homes Nissan has unveiled a system which enables the Leaf’s lithium-ion batteries to supply electricity to households This allows the Leaf to be used as an electricity storage device for houses in preparation for power outages – a particular concern in Japan, where power supplies have continued to suffer interruptions following the Fukushima nuclear crisis earlier this year.http://www.environmentalleader.com/2011/08/04/nissan-leaf-to-help-power-homes 20
  21. 21. Ford electric vehicles sold with solar PV systems and solar sunroof option Ford and solar panel maker SunPower Corp. have teamed up to offer a residential solar system designed to offset the electricity used to charge Ford’s new Focus Electric vehicle, which debuts later this year. ` In January, Ford announced an agreement with consumer electronics retailer Best Buy to offer a 240-volt home charging station for electric vehicle owners.
