One component of the Super Circuit project is a microgrid: a small generation and distribution grid that can be self-sufficient locally but also operates tied to the utility grid. Microgrids are conceived of as a way of integrating home- or neighborhood-scale generation sources into the larger system and a way of reducing the scope and severity of outages, but they introduce variables that utilities need to understand better.

The Super Circuit microgrid installation — a 160-kilowatt natural gas generator, a 40-kilowatt solar array and three lithium-ion batteries that can put out a total of 24 kilowatts of power for two hours, all to be wired into two commercial buildings at Research Ridge technology park in Morgantown — will serve as a laboratory for exploring those variables.
