2. //plug-in ready michigan //powerpoint// Objectives Perspective from utilities on impact of PEVs Assess utilities state of readiness Identify primary issues and concerns Offer recommendations

3. //plug-in ready michigan //powerpoint// Process Active engagement with utilities MPSC PEV Readiness Taskforce MPSC Smart Grid Collaborative Other related programs Primary research Secondary research

4. //plug-in ready michigan //powerpoint// Report Structure Background Information PEV Readiness – Current State PEV Readiness – Future Perspective Summary, Conclusions, Recommendations

5. //plug-in ready michigan //powerpoint// Background Information The role of utilities Michigan utilities Types in the State of Michigan Service areas Scale Generation sources Energy loads

6. //plug-in ready michigan //powerpoint// PEV Readiness – Current State Initial data on charging behavior Charging locations Charging levels Utilities process for addressing new loads Evaluation Planning Issue identification and resolution

7. //plug-in ready michigan //powerpoint// PEV Readiness - Future State Engagement in market evolution MPSC Readiness Taskforce MPSC Smart Grid Collaborative EPRI Programs NARUC Activities

8. //plug-in ready michigan //powerpoint// PEV Readiness – Future State Reality of timing and scale Demonstration programs Vehicles Infrastructure Historical ability to respond

9. //plug-in ready michigan //powerpoint// Utilities Concerns Utilities concerns Time of use Lack of notification Clustering Higher charging levels

10. //plug-in ready michigan //powerpoint// Time of Use PEVs charging at same time Exacerbate peak loads Create new peak load periods Can be influenced by rate programs

11. //plug-in ready michigan //powerpoint// Lack of Notification Direct impact on localized load Notification provides the opportunity to apply evaluation process in a timely manner Small number of PEVs can result in localized issues (clustering)

12. //plug-in ready michigan //powerpoint// Clustering Multiple vehicles in close proximity Residential Commercial Localized load on infrastructure More critical in older neighborhoods Difficult to plan

13. //plug-in ready michigan //powerpoint// Higher Charging Levels Current market emphasis is on AC Level 2 Early data suggesting AC Level 1 sufficient for many customers Market being influenced by “range anxiety” and nature of current gas based system Higher levels, e.g. fast charging, more applicable to BEV Anything beyond basic AC Level 2 increases potential for issues with the grid

14. //plug-in ready michigan //powerpoint// Resulting Issues Transformer overloads Subsystem upgrades Local control panel Power drop to location Wiring Economics – increased demand charges

15. //plug-in ready michigan //powerpoint// Summary, Conclusions Michigan utilities actively engaged Michigan utilities creating and implementing strategies to address major issues Michigan utilities have policies, procedures and plans in place to respond to the growth of PEVs

16. //plug-in ready michigan //powerpoint// Recommendations Promote open and timely communications with the utilities Expand education tools and publications to include all phases of PEV ownership Continue to allow utilities to experiment with and offer PEV/TOU rate programs Develop and institute a consistent means of notification on the location of PEV owners

17. //plug-in ready michigan //powerpoint// Recommendations Support education and implementation programs that promote workplace charging The Michigan legislature should consider an increase in the RPS to reduce Michigan’s carbon footprint associated with PEV charging
