Connecticut solar is changing the electric grid. Here's what it could mean for electric bills here
On a sunny drive through Connecticut, rooftop solar is easy to spot on homes, barns and businesses. Its effect on the electric grid is less visible. Though the panels generate power close to where it is used, they do reduce how much electricity the regional grid must supply. Then, as the sun sets and solar production fades, demand on the grid climbs again. That daily dip and rise is called a "duck curve." It describes a day when electricity demand served by the grid is lower at midday than overnight. On a chart, demand falls when solar output is high, then rises in the evening as that output declines, forming a shape that resembles a duck. Duck-curve days are a sign, in one sense, of solar's growing contribution. When the weather cooperates, rooftop panels reduce how much electricity New England needs from the grid during the day. But as solar output fades at sunset, grid operators must…
