Things are different in Australia, but eventually the V2G will become common in America soon. Also VPP – virtual power plant, which combines many residential solar storage systems into a virtual power plant. This is being done right now in California.
What is really heartbreaking is there has been so much badmouthing about EVs – electric vehicles are going to overload the grid. The truth is the growth of EVs is about 8% which is less than the growth of the grid in the past. Plus if the grid gets VPPs and V2G the EVs and home batteries will help save the grid from being overloaded.
But these will cause changes in the financial ways electric utilities run their business. They will have to pay their customers for sending electricity back to the grid. The VPPs would be generating power and selling it back to the utilities during peak times when power is the most expensive.
