ERLANGER, Ky. -- One gizmo allows you to run the dishwasher when electricity is cheapest. Another decides when to fire up the water heater if you plan on a 6 a.m. shower. Another routes solar energy from a rooftop panel to a battery in your garage and the wiring in your house.
Outside, towers equipped with sensors tell the electric company exactly where a storm has knocked out power. The power grid itself can react to trouble, rerouting juice from a healthy part of the system or isolating itself to prevent a larger meltdown.
So far, this dramatization of "smart grid" technology is confined to an office park in northern Kentucky, but sponsor Duke Energy is one of many large utilities confident they can turn theater into reality for millions of customers, aided by billions of dollars in the federal stimulus package.
Smart grid is an essential component of President Obama's plan to change the nation's energy habits and reduce U.S. dependence on fossil fuels, especially foreign oil. It would energize his hopes for more jobs and fewer pollutants while remaking a network still moored to the 1950s.
