California ISO updated roadmap advances electric vehicle plan

The California Independent System Operator Corporation (California ISO) has released an updated roadmap that will help guide electric vehicle (EV) integration into the power grid as well as support California Gov. Edmund G. Brown Jr.’s 2012 executive order to get 1.5 million zero-emission vehicles on California roads by 2025.

The California Vehicle-Grid Integration Roadmap: Enabling Vehicle-Based Grid Services is among one of the first strategies outlined in the governor’s ZEV action plan published in March 2012. This strategy along with others in the action plan will be featured at the upcoming governor’s Office Summit on Zero Emission Vehicles.

The ISO roadmap outlines the strategies that lead to implementing the technologies and policies that would support electric vehicles providing valuable services that contribute to the reliable operation of the power grid. This includes policies that promote smart charging and vehicle-to- grid integration.

Smart charging involves one-way communication and power flow from the grid to the vehicle and occurs when customers choose when to charge their vehicle based on price or other signals. Vehicle-to-grid integration involves two-way communication as electricity flows from the grid to the EV battery and from the EV back to the grid.

The roadmap points out some near-term wins, such as using smart charging strategies that align with grid conditions so electric vehicle owners, individuals and fleet owners can keep their batteries full while not increasing peak load. This will help avoid the need to build additional generation and transmission costing millions of dollars.
