EV Strategic Plans
30
Sagewell, a consultant, developing EV Strategic Plans for power agency members with 50/50 grantApex, Wake Forest, and Shelby, have worked with Sagewell to develop plans; Greenville starting a plan nowStrategic plans evaluate the impact that EVs could have on the electric distribution system, marginal revenue potential, market availability of EVs, consumer savings, and positive CO2 impact
Passive Load Shifting via Bring Your Own Charger (BYOC) Program
31
Sagewell uses the Bring Your Own Charger (BYOC) program to passively shift 95% of EV load to off peak hours
Uses the electric vehicles on board programming capability to schedule when the car will charge
EV charging behavior verified one of two ways:
AMI dataOEM telematics (no hardware)
32
AMI Analytics of EV Load Profile• Sagewell uses real-world AMI data
from known electric vehicles to
calculate EV value and assess load
and peak impacts.
• Actual EV behavior isn’t quite what
is assumed
• Average afternoon peak load
contribution, for even high kW
vehicles, is between 1kW and
1.5kW

475,000 buses
School Bus Industry
• Operations - Predictable 4 to 6 hours of daily AM/PM routes• Low utilization – Used 180 days/year and typically stored in centralized parking depot• Across Dominion’s VA and SC service territory, there are over 12,000 school buses

Vehicle to Grid Technology
Increased Safety
Cleaner Air & Zero Emissions
Phase 1 Deployment

50 Thomas Built C2 Jouley Buses • 77 Passenger Bus with 3-point seat belts• 220 kWh battery system with 130+ mile range• Battery system and V2G chargers provided through Proterra• Dominions owns battery and related components• Electric bus acquired at no extra cost to district vs diesel bus*• School districts to retain fuel & O/M savings, likely at least
$7000/bus/year
Charging Infrastructure• 60kW bi-directional power control system (PCS)• Each PCS feeds either one dispenser or two dispensers sequentially• Infrastructure cost & installation is covered by Dominion Energy
Locations• 15 school districts in Dominion Energy Virginia’s service territory• Charging infrastructure installed at the district’s bus depot
Length of Program• Each bus will operate for at least 15 years• Battery is covered by warranty through this entire period• Agreements are signed by each locality for participation
* District is required to purchase 3-point seat belts option in order to participate in the program
Dominion Energy & VA Deployment Plan
Phase 1 - 2020/2021• 50 buses to be fully operational within VA service territory by Jan 2021
Phase 2 - 2021/2025*• At least 1000 buses over 5-year period to replace aging diesel fleet• V2G impact, 1000 buses equates to 220 MW, enough energy to power
roughly 10,000 homes for about 4 hours
Phase 3 - 2025/2030*• 2025 Goal that 50% of all diesel bus replacements will be electric• 2030 Goal that 100% of all diesel bus replacements will be electric
41
VW Settlement Funds• Dominion Energy will collaborate and assist with Virginia’s DOE &
DEQ with their allotment of $20 million dollars towards accelerating electric school bus deployments outside of Dominion’s territory
* Pending Virginia General Assembly Approval
Innovations Heading into Phase 2
42
School Bus Offerings*• A fourth key market player, Navistar with it’s IC Bus, will start
offering an electric school bus in 2021 that is V2G capable• Existing market includes Thomas, Lion, and Blue Bird
Charging Systems• Proterra is moving from a 60kW PCS to 1.5MW PCS
o Charges up to 20 buses at 75kW simultaneously• Nuvve partnering with Blue Bird and Lion
o Currently offering 60kW bi-directional charger
Battery Sizes• Battery sizes now exceeding 220kWh
o Navistar announced a battery option up to 315kWh
*Dominion Energy plans to award buses from at least 2 bus vendors in future phases
