Report: VW Exec Talks Sending Power Back into Grid with EVs

While consumers may worry about the effect of a fleet of EVs on the nation’s electrical grid, Volkswagen says that all of these batteries hooked up to the grid could help both it and consumers while potentially reducing electric bills.

Speaking with journalists in Berlin, VW chief strategist said that “By 2025 we will have 350 gigawatt hours worth of energy storage at our disposal through our electric car fleet. Between 2025 and 2030 this will grow to 1 terawatt hours worth of storage,” Reuters reports.

“That’s more energy than is currently generated by all the hydroelectric power stations in the world. We can guarantee that energy will be used and stored and this will be a new area of business”

Because EVs aren’t driven all of the time, their large batteries can be used as storage for the grid, even being used to power homes in cases of outages. Don’t have a long commute home or the car’s sitting in your driveway? Let the grid pull power out during the day, easing peak loads, then let it charge back up at night when demand is less and power rates are cheaper. This type of charging could also help balance peak and off-peak loads, helping to make the existing grid more efficient, especially with sources like wind power, where the wind still blows even if demand is low.

How this could be used to make money for consumers or automakers is still being worked on, but we have confidence someone will find a way to profit from it.
