Sets Forth Three Routes to Electric Vehicle-Grid Connectivity:
Vehicle-Grid Integration Using V2G Can Enhance Value of EVs

California Independent System Operator Corp, which manages the California electric grid on behalf of the state’s three large utilities, has released a document it says will help integrate electric vehicles into the grid, and thereby improve their value. updated December 31

Cal ISO’s 44-page California Vehicle-Grid Integration Roadmap: Enabling Vehicle-based Grid Services ‘builds upon efforts already underway in both the private and public sectors to enable EV aggregations.’

Cal ISO’s 44-page California Vehicle-Grid Integration Roadmap: Enabling Vehicle-based Grid Services ‘builds upon efforts already underway in both the private and public sectors to enable EV aggregations.’

The Vehicle-Grid Integration Roadmap: Enabling Vehicle-based Grid Services “outlines three inter-dependent tracks to assess how consumer use of electric vehicles could benefit electric reliability, and to determine policies and technologies necessary to elicit that value through appropriate market signals for a more reliable, sustainable electric grid,” Cal ISO says.

“Vehicle electrification promises to not only help fight climate change, it presents an opportunity to provide grid services that complement other energy sources to meet the reliability needs of the grid,” ISO president and CEO Steve Berberich said in a release.

VGI Encompasses V2G

A key aspect of VGI is V2G – for vehicle-to-grid – whereby electricity stored in electric vehicle batteries can be given back to the grid in times of peak demand. Cal ISO calls it “the bidirectional flow of power.”

“As the electricity system in the state evolves, now is the time to advance coordination with state agencies and stakeholders to realize the untapped benefits from widespread use of electric vehicles,” ISO regulatory affairs director Heather Sanders says in the Roadmap announcement.

“Creative approaches identified in this roadmap are expected to lead to EV charging behavior that is beneficial or at least not adverse to grid reliability,” states the executive summary. “This roadmap also promotes the aggregation of EV resources that can be bid into the ISO’s wholesale market as grid services – leveraging the synergies between EVs and the grid.”

1.5 Million California ZEVs by 2025?

The three interdependent “tracks” are determining VGI value, developing enabling policies, and supporting technologies and product to make it all work.

The organization says it is following up on a 2012 executive order by Governor Jerry Brown setting a target of 1.5 million zero-emission vehicles on California roads by 2025, with a ZEV action plan calling for Cal ISO to lead a coordinated effort in league with the California Energy Commission, California Public Utilities Commission, California Air Resources Board, the Governor’s office and industry stakeholders.
