As states across the country brace for the wave of electric plug in vehicles to hit the streets, utility companies warn that there could be glitches. A smarter electrical grid has been developed to accommodate the surge in power usage, and utility companies have been working with the automakers to ensure a smooth transition, but too many drivers trying to charge their vehicles at the same time, could lead to low voltage situations.

Executive vice president and chief operating officer of Novi-based ITC Holdings Corp., said that as plug-in use grows and more public charging stations are installed, substations or lines may need to be upgraded. Experts, however, don’t believe electric vehicles will be widespread until 2020, giving utilities at least a decade to figure out ways to handle new loads and educate consumers about scaling electricity during peak times.

For now, utilities are installing smart meters in homes and businesses to help consumers better manage electricity use. The meters allow utilities to charge rates based on peak and off-peak use and track that data. This will encourage drivers to charge in off peak hours as well as give information on where upgrades need to be made. As technology advances, cars plugged in for recharges could actually help the grid, said Scott Miller, director of Coulomb Technologies’ ChargePoint America. “These can act as remote storage units, transferring some of the energy from the cars back to the electrical grid in times of need.”
