Massoud Amin is director of the University of Minnesota’s Technological Leadership Institute, an organization dedicated to forming connections between engineering, science, business and technology. Amin, a professor of electrical and computer engineering, recently was listed as a mover and a shaker in the smart grid industry by GreenTech Media. He is also chairman of the IEEE Smart Grid Newsletter. In an abridged email interview, Amin discusses the smart grid with Government Technology.
Scenarios for a smart grid vary wildly. But a common understanding [is] that in the coming years, electricity will play a much greater role in global society. It is entirely possible that nations, regions and cities that best implement new strategies and infrastructure could reshuffle the world pecking order. It’s very possible that emerging markets could leapfrog other nations in smart grid markets and deployment.

How can we have one? Smart grids have the potential to substantially reduce energy consumption and CO2 emissions. In fact CO2 emissions alone could be reduced by 58 percent in 2030, compared to 2005 emissions.
Microgrids that localities build to serve campuses, communities and cities will contribute to smart grid sustainable benefits. Microgrids are wonderful examples of the “think globally, act locally” principle. They draw their energy from locally available, preferably renewable resources. They use smart grid technologies to continually monitor customer demand, and they offer innovative pricing and other programs to manage the load and encourage customers to conserve energy. The microgrid ships any excess capacity back into the grid.
I’ve mentioned the overloaded grid conditions we have today. Yet the situation is certain to get much worse, especially with the increasingly digital society. Twitter alone puts a demand of 2,500 megawatt hours per week on the grid that didn’t exist before. Because of increasing demand, experts believe that the world’s electricity supply will need to triple by 2050.
It needs a self-healing infrastructure to ensure that [the] power grid can continue to operate reliably for businesses and consumers who depend on it. A smart grid that is overlaid with the various sensors, communications, automation and control features that allow it to deal with unforeseen events and minimize their impacts will be resilient and secure.
Not only can a self-healing grid avoid or minimize blackouts and associated costs, it can minimize the impacts of deliberate attempts by terrorists or others to sabotage the power grid.
