Smart Wires Inc. – Powering the Future


We design and manufacture advanced power flow control solutions that dynamically push or pull power on the high voltage electric grid: Gregg Rotenberg, CEO & President.

With technology evolving, the energy and utility industry is facing a time of unprecedented uncertainty. This has created complex challenges and opportunities across the sector, with new solutions and a growing number of industry players.

In light of the above mentioned, we are delighted to present Smart Wires, Inc. – dedicated to providing grid optimization solutions for transmission organizations worldwide. The firm offers power flow control solutions to utilities.

Smart Wires was established in 2011 and is headquartered in California’s San Francisco Bay Area with additional offices in Ireland, the United Kingdom, and Australia.

Interview Excerpt: Gregg Rotenberg, President/CEO

Why was the company set up? How did you select the vertical and decide to be a part of the global platform?

Smart Wires technology was developed by utilities for utilities, led by a consortium of large U.S. utilities at the National Electric Energy Testing Research and Applications Center (NEETRAC). This core group of utilities, which included Southern Company and the Tennessee Valley Authority (TVA), defined the vision for the original modular power flow control system. Today, the technology is rapidly becoming part of the utility tool kit as more and more electric utilities explore new ways to mitigate future uncertainties surrounding load and generation, alleviate congestion, improve network utilization and maintain reliable electric service.

What learnings helped you to set this company up?

The need for Smart Wires breakthrough technology could not be greater. Electric grids across the world are facing a power congestion crisis, costing everyday consumers billions of dollars in higher energy costs each year. Congestion on the electric grid is the result of physical limitations of specific grid components. As a result, it prohibits the amount of power that can flow over to portions of the transmission network without jeopardizing system reliability. Bottlenecks on the system prevent lower cost, cleaner power from reaching consumers. System limitations for transporting clean power mean that a higher polluting generation source may be used instead.

Tell us about your first product that was launched.

In 2012, TVA  installed 100 Power Line Guardian devices. This installation was the first deployment of Smart Wires’ innovative power flow control solutions and a significant step for TVA as they sought to develop their future grid. TVA’s fleet of PowerLine Guardians has been operating reliably for the past five-and-a-half years.

What do you feel is the reason behind your product’s popularity?

Today’s electric grid has become extremely difficult to manage, due to a rapidly changing power generation mix, evolving electricity consumption patterns and challenges associated with permitting and building new infrastructure. Utilities are demanding more economic, flexible solutions. Industry experts have drawn attention to the fact that global power grids were built without “valves” to control the flow of power. Visionary utilities have recognized it is time for a new paradigm for designing and managing their grids.

Our solutions provide the first highly intelligent “valve” for transmission grids. We design and manufacture advanced power flow control solutions that dynamically increase or decrease line reactance. With these tools, utilities can push power away from congested lines on to underutilized paths and unlock the excess capacity that exists on their networks today. These solutions install quickly and can be easily relocated, providing the flexibility needed in today’s uncertain landscape. With Smart Wires, utilities can actively dispatch transmission lines, just like generation or load, and create a dynamic grid.
