Rideshare services like Uber and Lyft are offering more electric vehicles, boosting the need for fast charging. That may help the grid in high-solar states like California.
Electric-vehicle charging at scale could be a blessing or a curse for the grid.
In the best-case scenario, plug-in vehicles charge up at times that align with needs of the power grid. In the worst case, they strain the system, creating a new challenge for grid operators.
