#Grid May or May Not Be Ready For Electric Vehicles - #EVs


 “Now is the time for everyone to prepare.”

Some Americans appear increasingly ready to give up their gas cars for electric vehicles. But are the country’s electric grids prepared for them?

The question is a critical one in the quest to address climate change, because transportation is now the single largest sector contributing to U.S. greenhouse gas emissions. EVs are widely viewed as a key way to help change that.

“The broad answer is actually yes, the grid can handle the introduction of large amounts of EVs,” said Matt Stanberry, vice president of Advanced Energy Economy, a business association dedicated to development of clean and affordable global energy systems. “The capability is there,” Stanberry said. “The question is how do you get there.”

Stanberry, along with others looking at the issue, believes what’s needed is not more power, it’s more efficiently and strategically provided power.

“Cars sit around 20, 21 hours a day. There’s plenty of time to charge – so quite a bit of flexibility,” said Dan Bowermaster, program manager for electric transportation at the Electric Power Research Institute, an independent non-profit center for public interest energy and environmental research, which has been looking at grid readiness for EVs.

But he said with new technology coming, such as storage and the ability to use a vehicle’s battery to power a home or to provide extra power to the grid, “Now is the time for everyone to prepare.”
