I have written about vehicle to grid (V2G) technology and pilot projects in the past but real tangible projects are now coming thick and fast. In this instance EMotorWerks are aggregating their network of 10,000 EV chargers in California to provide demand response services to the California ISO. They are also looking at accessing frequency regulation markets in the near future and other grid services markets which would provide additional income for EV owners. California has the volume of infrastructure required to aggregate to provide these services and as other regions and providers get to that critical point we should see this as commonplace worldwide.
The company oversees more than 10,000 electric vehicle chargers in California and can delay charging schedules across that fleet based on a signal from the grid operator, while factoring in drivers’ needs and letting them opt out of events if necessary. Drivers earn compensation based on the flexibility that they provide. Of the 10,000 chargers, 6,000 have been installed since the start of 2017, amounting to 30 megawatts of flexible capacity.
