Utilities Concerns

Utilities concerns

Time of Use

PEVs charging at same time

Exacerbate peak loads

Create new peak load periods

Can be influenced by rate programs

//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)

//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

//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

//plug-in ready michigan

Resulting Issues

Transformer overloads

Subsystem upgrades

Local control panel

Power drop to location

Wiring

Economics – increased demand charges

//plug-in ready michigan

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

//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

//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
