May 2019Charging Sessions By Start Time

11

VTA working with Prospect Silicon Valley, and Bay Area tech companies to pilot a cutting-edge system that will manage charging and energy consumption on electric buses while reducing the impact on the state’s electricity grid.

Funding from the California Energy Commission will serve as a major case study for transit agencies throughout the country

Connected & Making Real Time Decisions

Vehicle to Grid Integration (VGI) Collaboration: PARTNERS

12

Primary Goals of the VGI Solution

1. Ensure buses are charged and ready to go before pullout time2. Provide visibility into charging process3. Send alerts when issues in the charging process or during daily operation need to be addressed4. Support the assignment of bus to block process5. Minimize PG&E utility bill6. Simulate Grid interactions with system 7. Simulate New Block & Charging Options

What Are The Major Innovations?

• Creating charge plans that support more buses than charge stations

• Energy Management Platform that interoperates with VTA and grid systems

• Dashboard and alerting system supporting vehicle charging & operations NEXT STEPS

Smart Microgrid +Second Life Li-IonEnergy Storage

Expanded Solar

• Realtime cost minimization process through demand leveling and time of use aware charging

• Performing grid service simulations while not jeopardizing the bus charging operations

Key Takeaways

• Going zero emission will dramatically reduce an agency’s carbon footprint and improve air quality

• Sustainability Programs can help ensure that electricity is used as efficiency as possible and is as clean as possible

• Sustainable fleet electrification will require managing electricity usage and cost on a regular basis
