Grid Reliability — on Wheels

Within about four years, the total electricity stored in electric vehicles in Texas will equal the entire capacity of the ERCOT power grid. 

Electric vehicles are now one out of every eight cars purchased in the world and about one in 20 in Texas. More than 179,000 Texans now own electric vehicles. And EVs have an average battery capacity of 67kWh. So right now, at the very dawn of this boom, Texans now have 12,000 megawatts of power sitting in their garages. That’s enough to power the entire Houston area for an hour.
