2. Page 2 | What is an Electric Vehicle (EV)? Tesla is another example of BEV.

3. Page 3 | Increasing Availability of Models and Brands

4. Page 4 | How Widespread is EV? Georgia tax credit of $5000 (now expired) on top Federal $7500 were the stimulants that pushed metro-Atlanta on top of the list of cities having highest concentration of PEV. But with state tax credit gone, will PEV continue to grow?

5. Page 5 | Gas Price Trend (from 2005) High gasoline price at the pump in 2011 – 2014 also drove up demand for PEV. In 2015-2016, depressed gas price may have the opposite effect.

6. Page 6 | Why EV? Individual Level Lower and more predictable fuel prices Lower maintenance costs Reduce/eliminate trips to gas station Quiet performance Quick acceleration Improve local air quality Fuel expenditures are local Higher customer satisfaction Macro Level Reduce/eliminate Green House Gas emissions Reduce national oil dependency

8. Page 8 | Impact of EV charger on Residential Load Depiction of typical residential electricity usage throughout the day and the impact of PEV charger against the City’s peaking period. 12PM-7PM is the most frequent peak periods for the East Point’s aggregated load All other hours are non-peak hours. Residential PEV rate should incentivize consumers to avoid charging PEV during peak period, yet stimulate charging during non-peak period.

9. Page 9 | Average Market Price (2010 – 2015 YTD) East Point’s excess energy was traded at the price above (on average). Note that summer has one continuous peaks, while winter have two separate peaks.

10. Page 10 | Proposed East Point’s EV Charging Rate Residential Plug-in Electric Vehicle (RPEV) Requirement: Charging station separately metered from standard residential usage  Summer (May - October)  Peak: Monday – Friday 12:00 PM – 7:00 PM excluding holidays  Off-Peak: All other hours & holidays  Winter (November – April)  Peak: Monday – Friday 7:00 AM – 11:00 AM, 7:00 PM – 9:00 PM excluding holidays  Off-Peak: All other hours & holiday Holidays include New Year, MLK, Memorial, Independence, Labor, Thanksgiving, Christmas)

11. Page 11 | Georgia Power’s Plugin EV Rate Time of Use Plug-in Electric Vehicle (TOU-PEV-5)  On-Peak (June – Sep, 2PM – 7PM, non-holidays)  Super Off-Peak (11PM – 7AM, every day)  Off-Peak (all other hours) Based on TOU-PEV-5, ECCR-5, NCCR-5, DSM-R-6, TOU-FCR-TP-1, NuclearWasteFundRider, MFF-4 http://www.georgiapower.com/residential/rate-plans/residential-tariffs.cshtml

12. Page 12 | Evaluating $200 Incentive for EV At $200 per account and 100 customers  $20,000 per years in cost Payback depends on charging station type and distance of trip  Charging stations In home/residential: Level 1 and Level 2 Commercial/Gas station: Level 3  Distance driven 30 miles daily commute

13. Page 13 | EV Chargers Level 1 Charger:  Inexpensive  Take longer  Charging for 30 miles requires  8 hours at 1.3 kW per hour = 10.4 kWh Level 2 Charger  Moderately expensive  Charging for 30 miles requires  3 hours at 3.3 kW per hour = 9.9 kWh  1.5 hours at 6.6 kWh per hour = 9.9 kWh Average about 10kWh per charge for 30 miles commute
