At the ARPA-E Energy Summit in Washington, D.C. last month, Smart Wire Grid had something of a coming-out party. The company has been around for a few years after growing out of Georgia Tech, but it was at the annual summit that Smart Wire Grid, a power flow controls company, was showcased as one of the successes of the Department of Energy’s research program.

Smart Wire Grid sells a device that clamps onto transmission lines to control the flow of power. Originally developed at Georgia Tech, the technology can monitor and even help redirect power flow. Once a problem has been studied at one location, the devices can be moved to other lines.

Power flow control hardware has been a particular focus of the GENI program — Smart Wire Grid, a startup that’s deploying distributed power flow control devices on transmission lines in a project with the federal Tennessee Valley Authority (TVA), was one company highlighted at the conference.
