Rich Quattrini - ChargePoint

2. High Level Goals
Provide utilities fine-grained individual and aggregated visibility to residential PEV charging loads
Establish communication protocols and information flows to allow utilities to use PEV charging as a tool to proactively manage local distribution circuit load
Leverage vehicle to charger emerging communication standards to vary and optimize the rate of individual vehicle charging while ensuring the total PEV charge needed is not compromised

4. Key Project Activities
ISO/IEC integration
Test and qualify a prototype interface enabling ISO/IEC communication with EVSE
Integrate ISO/IEC prototype interface stack into ChargePoint Home charger
Add proof of concept stack to BMW i3
Test and validate communication with BMW i3 and ChargePoint Home charger
OpenADR integration
Implement a communications interface via OpenADR 2.0b
Provide utilities visibility of the fine-grained individual and aggregated near real time charging data
Enable utilities to provide signals or TOU pricing to help manage within specified load limits
Builds on existing OpenADR 2.0a capability – adds critical features for 2.0b
Enhance existing ChargePoint driver application and NOS
Will accommodate additional elements for customer defined preferences, opt-out, and information exchange as it relates to project
Requires changes or enhancements to existing driver notification and interactivity features

5. Key Project Activities (cont.)
Identify, with input from SDG&E, preferred target systems/feeders for pilot-scale residential application
Educate, recruit drivers and install 30 ChargePoint chargers with pilot customers at San Diego Gas & Electric
Implement pilot in SDG&E area
Pilot Project Report – evaluation of benefits
Knowledge transfer / Production readiness

8. Topics for Further VGI Research
More studies on the future value of grid services and payback
What is the impact and economics for all the players involved?
Driver
Site owner / host at metering point
Aggregator
Control systems / optimization software provider
Scheduling coordinator
LSE / utilities
Vehicle OEM’s
Some studies make aggressive assumptions
Basing grid value of EV services on FR market value in PJM not realistic
As more resources bid in, prices will come down
What will the value be in California for AS and FR services in the future?
What other markets might make the “juice worth the squeeze?”
Are values sustainable and predicable enough to recover costs?
Better estimates on the future value of local services
Local area market pricing
Avoided costs of distribution upgrades, etc.
