4. Typical Utility Pad Mount
Transformer

5. Potential Impacts to Electric
Distribution System
 Typical 240 volt
charging station
could nearly double
the electrical
demand of the
average home

6. Mitigation for New EV Charging
Loads
 Invest in expensive infrastructure
upgrades
 Optimize existing infrastructure
with Smart Grid technologies and
pricing signals

utilities to have full deployment of
“Smart” meters

8. Some Benefits of Smart Grid and
Advance Metering Infrastructure
 Monitor System Status
 Pricing Signals – TOU Rates, Real Time
Pricing
 Interruptible Options – delay charging,
threshold

9. Solar PV Customer Rebates
 MID has a solar PV
incentives to

price
 Smart Grid interface with Smart
Charging technologies
