The U.S. Energy Information Administration reports that the real price of electricity has dropped by a factor of 45 over the last 120 years in the United States. Ongoing innovation is required to continue delivering low-cost and reliable electricity. Recent initiatives to increase the intelligence and control of the power system have transformed planning, operations, and maintenance.
KNOXVILLE, Tenn. ─ The Tennessee Valley Authority is testing a promising “smart grid” technology that may help utilities enhance reliability, efficiency and the ability to keep power flowing.
Ninety-nine devices designed to reroute electricity, automatically or by remote control, from potentially congested transmission lines onto underused lines have been installed on a 161-kilovolt transmission corridor […]
Tennessee Valley Authority (TVA) is a strong advocate of finding new and innovative ways to modernize the grid. Through the Smart Wire Focused Initiative (SWFI), spon- sored by the National Electric Energy Testing, Research and Applications Center (NEETRAC), TVA has teamed up with the U.S. Department of Energy’s (DOE’s) Advanced Research Projects Agency–Electric (ARPA-E) and Smart Wire Grid Inc. (SWG) to deploy an array of distributed series reactance (DSR) units.
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.

Smart grid technology, on the other hand, doesn’t require extensive replacement, but only add-on information systems. Implementation of smart grid technology can speed up repairs and isolate damaged sections while keeping intact sections powered up. Smart Wire Grid, a startup out of Oakland, CA, has been installing its information devices, Distributed Series […]
Out of the hundreds of energy innovations on display this week at the annual ARPA-E Summit just outside of Washington D.C., it’s been rare to find a group actually selling and shipping products. But a startup out of Oakland, Calif. called Smart Wire Grid has quietly begun delivering devices that clamp onto transmission lines and control the flow of power.
A pilot demonstration of Smart Wire technology is now under way on the Tennessee Valley Authority’s power transmission system. Installed on a 161-kilovolt transmission line near Knoxville, Tenn., the Smart Wire system is designed to provide congestion relief by redistributing power flow onto underused lines, thereby optimizing transmission system operations.
