3. 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

5. 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

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
6. Phase 1 Deployment
6
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
7. Innovations Heading into Phase 2
7
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
JM cited - https://www.atu.org/work/school
Every year, school districts spend about $22 billion on student transportation and 500,000 yellow buses travel our roads daily. 55 percent of K-12 students ride the bus to school. School bus drivers across the country are entrusted with the care and safety of more than 25 million children as they are transported to and from school and school-related activities. In total, school buses provide 10 billion annual student rides.

Phase 1 VA applications: fleet size of applicants = 9,481
Same Acquisition Cost + Less Maintenance
Cost to upgrade from a diesel to electric model covered by program, including infrastructure
Reduce operation & maintenance costs for schools by 60%
Districts to keep O&M savings
Electric Bus Charging
Equivalent of 17 MPG compared to 6 MPG for diesel
Charging stations & infrastructure provided at no cost to school
Increased Safety
Electric buses are quiet, allowing for better communication between drivers and students
Every bus is equipped with 3-point seatbelt for each student
Cleaner Air & Zero Emissions
The air quality inside a diesel bus is 5x worse than outside the bus. Replacing a diesel bus with an electric bus significantly improves air quality for students inside the bus and for the communities we serve.
One electric bus reduces C02 emissions by 54,000 pounds each year
Replacing 1,050 buses over 5 years with new electric ones will reduce emissions by 810 million pounds, the equivalent to taking 78,000 cars off the road!
Vehicle to Grid Technology
① The buses are all electric & can be used as portable batteries.
② When not in use, they can be tapped as an energy resource through vehicle-to-grid technology.
③ If energy needs are high or if renewable resources are intermittent, the batteries can provide stability to the grid.
④ During a power outage or emergency, the batteries could serve as mobile power stations.
VW Settlement Funds
The Virginia DEQ will be helping to accelerate the deployment of school buses through it’s allocation of $20 million dollars from the VW settlement funds
Dominion Energy will assist the DOE and DEQ in this initiative
