  1. 1. Electric Vehicles Utility PerspectiveModesto Irrigation District
  2. 2. Timing is Everything
  3. 3. Typical Utility Pad Mount Transformer
  4. 4. Potential Impacts to Electric Distribution System  Typical 240 volt charging station could nearly double the electrical demand of the average home
  5. 5. Mitigation for New EV Charging Loads Invest in expensive infrastructure upgrades Optimize existing infrastructure with Smart Grid technologies and pricing signals
  6. 6. ARRA Smart Grid Grant MID has received a $1.5 million Smart Grid grant from the department of energy (1 of 100 utilities nationwide) MID was one of the first California utilities to have full deployment of “Smart” meters
