  39. 39.  Electric vehicles represent a new type of load for us – one that is mobile, temporary and that can stress or fail local infrastructure in small numbers.
  40. 40.  Electric vehicles represent a new type of load for us – one that is mobile, temporary and that can stress or fail local infrastructure in small numbers. We need to understand the impacts even one electric vehicle can have on our system and decide how we are going to address them going forward
  41. 41.  This one load can be plugged in at multiple points on your distribution system.  The charger can be used by multiple EVs
  42. 42.  This one load can be plugged in at multiple points on your distribution system. It can also be plugged in while inside another utility service area.  Do we care about this?
  43. 43.  This one load can be plugged in at multiple points on your distribution system. It can also be plugged in while inside another utility service area.  Do we care about this?  Vehicle to grid (V2G) impacts – we would likely want to know where the vehicle is located before we dispatched the energy in the battery.
  44. 44.  People trade cars on a fairly regular basis. Wrecks, dissatisfaction, selling of a home, even divorce can create a “here today, gone tomorrow” situation.
  45. 45.  People trade cars on a fairly regular basis. Wrecks, dissatisfaction, selling of a home, even divorce can create a “here today, gone tomorrow” situation.  How does this impact your service policies?
  46. 46.  People trade cars on a fairly regular basis. Wrecks, dissatisfaction, selling of a home, even divorce can create a “here today, gone tomorrow” situation.  How does this impact your service policies? ▪ Example - Will you upgrade a transformer and service on the same basis as for the addition of more permanent load?
  47. 47.  The Nissan Leaf will require about 6.6KW for charging in a typical residential setup. Other models will have different charging requirements.
  48. 48.  The Nissan Leaf will require about 6.6KW for charging in a typical residential setup. Other models will have different charging requirements. For MTEMC, this is equivalent to an additional home on the transformer.

  59. 59.  A consistent process of notification would be ideal, but as yet it does not exist.
  60. 60.  A consistent process of notification would be ideal, but as yet it does not exist. Education is the key – let the different groups know how important it is for the utility to be involved from the beginning.
  61. 61.  A consistent process of notification would be ideal, but as yet it does not exist. Education is the key – let the different groups know how important it is for the utility to be involved from the beginning. We do not want to be seen as a roadblock to the early adoption of the new breed of electric vehicles
  62. 62.  Anything we require that results in additional cost to the vehicle purchaser will be scrutinized.
  63. 63.  Anything we require that results in additional cost to the vehicle purchaser will be scrutinized. However, we must not lose sight of the impacts that subsidizing electric vehicles could have on the rest of our customer base.
  64. 64.  Anything we require that results in additional cost to the vehicle purchaser will be scrutinized. However, we must not lose sight of the impacts that subsidizing electric vehicles could have on the rest of our customer base. This will be a challenge, and there are already differences in the way TVPPA members are approaching this.
  65. 65.  Do we need to add a separate meter for the EVSE?
  66. 66.  Do we need to add a separate meter for the EVSE?  Who pays for the separate meter? ▪ Separate EV rate ▪ Data only
