RICHLAND, Wash.--PNNL scientists foresee problems with electric grid. Scientists look ahead and see problems if too many electric cars are charging at the same time.
As more electric cars are purchased here is a worst case scenario. After work drivers plug in at the same time. That could cause rolling blackouts from too much demand in the early evenings.
PNNL Scientist Michael Kintner-Meyer says "as this level grows shorter and shorter the utility company will perform what's usually called rolling blackouts which will drop loads."
Scientists are anticipating new technology to prevent blackouts. The creation of energy demand response technology and more smart charge technology that can be used for more items than just cars.
