Editor's note: There’s no question that electric vehicles are a hot topic. They can potentially increase our energy independence while reducing our reliance on fossil fuel. Yet barriers are slowing adoption. We are all aware of common challenges such as cost, range, and the lack of charging infrastructure. But Michael Edmonds, the Vice President of Strategic Solutions for S&C Electric Company, says there is a "hidden" barrier -- the grid itself. When he explained his reasoning with me, I asked if I could share his insights with readers. I hope you will use the Comment form to explain if you agree or disagree. -- Jesse Berst

·         AMI and demand response offer a limited solution. For these technologies to reduce peak load, consumers must change their behavior. But that won’t happen without a reasonable price incentive that compensates consumers for their inconvenience. By contrast, grid-based technologies such as volt/VAR optimization and energy storage, shave peak demand without any consumer involvement.   

·         An optimized grid makes renewable energy available for EV charging.  Grid-based technologies can address the intermittency of wind and solar so EV owners can charge with green electricity, thereby reducing our dependency on fossil fuels such as oil and coal (in coal-fired plants).

·         An optimized grid provides the needed reliability. Electricity, the fuel source for EVs, must be at least as reliable as today's gasoline. Consumers will be even less tolerant of outages if it means they won’t be able to drive whenever they want. Grid solutions like distribution automation can lead to major improvements in electric service reliability.
