Southern Company, Georgia Institute of Technology (Georgia Tech), Smart Wires, and other partners have announced that they are collaborating on a new U.S. Department of Energy-funded project. Scheduled for 2025, the project will jointly implement advanced power flow control (APFC) and dynamic line rating (DLR) technologies to support the connection of renewable energy sources and new demand more quickly.

This project, led by the Georgia Tech Center for Distributed Energy with professor Deepak Divan as Principal Investigator, was selected by the U.S. Department of Energy in November 2021 as one of four projects to receive funding for grid enhancing technologies (GETs) that improve grid reliability, optimize existing grid infrastructure, and support the connection of renewable energy. It will use Smart Wires’ APFC solution— SmartValve™—in a mobile deployment combined with its DLR software—SUMO—and also develop control algorithms that improve and fine-tune how these solutions can work in synergy to optimize use of the grid. 

“The launch of this innovative project represents an important step toward more efficient and reliable integration of cleaner energy sources,” said Tim Lieuwen, interim executive vice president for Research at Georgia Institute of Technology. “This collaboration allows us to identify, develop and test new ways to manage the power grid in Georgia by co-deploying APFC and DLR technologies.” 

While the effectiveness of these solutions is well documented in multiple third-party reports, such as RMI’s GETting Interconnected in PJM, this project will be the first large-scale implementation of both technologies together. It will specifically examine their combined impact and result in the development of design control algorithms to unlock the combined power of these solutions and maximize their efficiency.  

SUMO identifies when lines have spare capacity based on real-time weather conditions, while SmartValves can redirect power flows to quickly utilize this spare capacity. This also applies in reverse, with SUMO identifying when the dynamic ratings of lines are less than the static rating. If it’s a hot day, for example, SmartValves can redirect power flows away from these circuits to others with capacity, reducing the risk of system faults while improving operational safety.   

The mobile deployment of SmartValves can be installed and in-service within one week. This provides a rapidly deployable solution that avoids extended outages and can be easily moved between sites as system needs evolve over time. 

“We’re delighted to provide both SmartValves and SUMO in this project to move the dial in terms of deploying multiple GETs in synergy and optimizing their use,” said Joaquin Peirano, General Manager for the Americas at Smart Wires. “The commitment of utilities like Southern Company to get the most from their existing grid with GETs, combined with the positive regulatory developments such as FERC’s recent Order 1920, positions the U.S. to capture the full value these technologies can provide on transmission grids.”  

The project will be delivered in 2025 and will involve a one-year performance period to provide Southern Company with operational experience that can be shared with other utilities and pave the way for greater use of GETs in the U.S.

In today's increasingly volatile world, the frequency of disruptions—whether due to natural disasters, geopolitical events, or supply chain interruptions—has grown. Recent challenges such as hurricanes, port strikes, wildfires, and global disruptions like the Suez Canal blockage, Panama Canal delays, and Red Sea freight issues have proven that the risk of major interruptions to business and personal life is no longer hypothetical. With the probability of a disruption higher than ever, the key question becomes: What prudent, no-regrets steps can individuals, families, and businesses take to assess and mitigate risk?

Assessing Risk: The First Step

A critical starting point for risk management is assessing the risks specific to you or your business. For individuals and small businesses, this process doesn’t have to be exhaustive. Rapid risk assessments can identify the most significant vulnerabilities with minimal effort, like assessing how a hurricane or supply chain disruption might impact access to essentials such as power or food. Larger businesses or municipalities might benefit from more systematic assessments, which can be conducted as part of an annual review.

Appetite for Risk vs. Potential Impact

Once risks are identified, it's important to balance your appetite for risk with the potential impact. An individual might be able to weather a short-term power outage, but a logistics provider or hospital must maintain continuous operations. For businesses, supply chain vulnerabilities—especially single-source suppliers—present a significant risk. By understanding where dependencies lie and preparing contingency plans, businesses can significantly reduce potential disruptions.

Low or No-Regrets Actions

The next logical step is to focus on low or no-regrets actions. These are relatively simple actions that provide immediate benefits with little downside. For individuals and families, this can be as straightforward as ensuring access to working flashlights, batteries, and emergency staples like water, rice, and beans to last at least a week.  Developing communication plans with family or neighbors is another critical preparedness step that costs very little but can be lifesaving.

For businesses, conducting an annual risk review is a no-regrets action that can identify critical risks and supply chain weaknesses. For single source suppliers, it may not be easy or practical to find a second supplier.  If not, go deep on that supplier and understand their upstream risks and ensure they are focused on risk mitigation. Small businesses can often a risk review in just a few hours, while larger organizations may need a more comprehensive review. Understanding infrastructure risks—such as power, water, and data reliability—is essential for businesses of all sizes. With each major disruption, such as wildfires or hurricanes, we see large companies caught off guard, often due to inadequate preparation for these well-known risks.

Tools and Resources for Deeper Risk Management

1. Failure Modes and Effects Analysis (FMEA)

FMEA is a widely used tool that helps businesses identify where and how processes might fail. It evaluates the severity, likelihood, and detectability of different failure points, allowing businesses to prioritize actions. In supply chains, FMEA is invaluable for identifying single-source suppliers or fragile logistical routes that could break down under pressure.

2. Business Impact Analysis (BIA)

BIA assesses the potential effects of a disruption on business processes. By identifying critical functions that must continue during an emergency, BIA helps businesses prioritize resources and plan for worst-case scenarios. This is especially useful for small businesses with limited resources, as it pinpoints where to focus recovery efforts during a crisis.

3. Risk Heat Maps

A risk heat map offers a visual way to assess risk by plotting the likelihood and potential impact of various disruptions. By color-coding risks, businesses can quickly see which areas require immediate attention. These maps are especially useful when making quick decisions in the face of a crisis, such as prioritizing responses to supply chain issues or extreme weather events.

4. Scenario Planning

For businesses with complex supply chains or operations, scenario planning helps explore different risk scenarios and develop flexible response strategies. This approach allows businesses to stay agile, with contingency plans ready for natural disasters, industrial actions, or global supply chain disruptions.

Structured Actions: Resources and Support

For those looking to dive deeper into risk management, there are several resources and programs available:

Executive Education Programs: For supply chain professionals, attending executive education programs such as those offered by Georgia Tech’s Supply Chain & Logistics Institute can provide in-depth knowledge and strategies for managing risk. These programs often cover real-world case studies and actionable risk management strategies.

Federal and State Resources: Agencies like the CDC provide accessible resources for disaster preparedness, such as the Zombie Survival Guide, a lighthearted yet effective framework for emergency planning. FEMA also offers guides for Business Continuity Planning (BCP), helping organizations design robust continuity strategies.

State Economic Development Agencies: Many state agencies, chambers of commerce, or small business associations provide business continuity support tailored to specific regions. For example, states prone to hurricanes or wildfires often provide detailed guides on how to prepare for natural disasters and mitigate infrastructure risks.

Building a Resilient Future

The key takeaway for both individuals and businesses is that resilience starts with proactive action. For individuals, preparedness may be as simple as having an emergency kit and communication plan in place. For businesses, risk management should be part of a structured, ongoing process. Annual reviews, risk assessments, and low-regrets actions can protect against significant disruptions, ensuring continuity even in the face of unpredictable events. By incorporating readily available tools and resources, we can all build a more resilient future, whether in supply chain operations, daily life, or community preparedness.

Nature doesn’t waste energy, and nature finds ways to adapt to a changing world. Understanding those two principles led David Frost to his interest in bio-inspired design. Frost, the Elizabeth and Bill Higginbotham Professor in Georgia Tech’s School of Civil and Environmental Engineering, has spent the last dozen years searching for ways to use nature’s efficiency and ingenuity to improve the civil engineering field. His efforts are paying off. In the last year alone, research from his lab has resulted in multiple patent filings, licensing agreements, and product launches — all of which take their inspiration from the biological world.

Many of those research projects have been the subjects of doctoral research by Frost’s students, with support and advisement from Michael Helms, co-director of Georgia Tech’s Center for Biologically Inspired Design (CBID) and the Brook Byers Institute for Sustainable Systems lead for biologically inspired design. The CBID mandate is to encourage researchers to find inspiration in the biological world, where design solutions have been in development for three-and-a-half billion years as life has on Earth has evolved. Building on the concept that nature isn’t wasteful, one of the goals of bio-inspired design is to develop products that are both energy and materially efficient, and therefore more sustainable.

As the subsurface exploration and excavation thrust leader for the National Science Foundation (NSF) Center for Bio-mediated and Bio-inspired Geotechnics (CBBG), Frost focuses on what’s going on below the planet’s surface. His inspiration comes from things like tree roots, earthworms, spider webs, and ant colonies. In fact, ants are what first got him interested in bio-inspired design.

“There are many organism systems that have not been thought of as necessarily the most intelligent systems. But in fact, they are following a set of rules, approaches, or guidelines and are producing things that, in the end, are both energy- and resource-efficient and adaptive,” said Frost. “One of these is ant colonies. We see the hills above ground, but what’s going on below the ground, with the tunnels and chambers, is fascinating.”

Early in his time with CBBG, Frost came across a Florida artist who made metal castings of ant colony structures. Frost acquired some, made more castings of his own, and then built digital models of ant colonies to understand how the structures maintain their strength. He also studied exactly how ants build such complex structures so efficiently.

“They take advantage of capillarity, arching effects, and the strength of spirals,” explained Frost.

Ants dig by carefully and quickly probing each grain of sand or dirt, in the same way a human might test a Jenga piece, before deciding whether it can be safely removed without damaging the tunnel. As a result, ants are extremely energy efficient as they dig, continually removing the least encumbered pieces of material. Based on this information, Frost and his team are exploring ways to improve the effectiveness and energy usage of tunnel-boring machines.

Other bio-inspired projects from Frost’s research that are further along in the development process include building anchors inspired by tree roots, a ground heat-exchange system based on spirals and plant xylem, a geogrid (or stabilization mesh) design based on spiderwebs, a worm-inspired soil probe, and another probe design influenced by a vortex and centipedes that would displace a minimum amount of soil.

“I'm convinced that just about any system in nature we look at will help us think about analogs for things that, as human engineers, we’d like to do — and do better,” said Frost. “The opportunities for inspiration and improvement are endless.”

Take the Root-Inspired Ground Anchor (RIGA), for example. Anchors are an essential element in construction, stabilizing retaining walls and other foundation structures. Traditionally, anchors are straight poles inserted into the ground. Looking at tree roots, Frost wondered if there was a better way. That thought led him to inventing an anchor that can be driven into the ground and then expanded under the surface, similar to the structure of tree roots. The expandable anchor improves load capacity by up to 75% and is about two-thirds as long as a conventional anchor. After years of refinement, the device has been patented, licensed, and is the basis of a startup founded by Ph.D. student John Huntoon.

Frost takes the most pride in the real-world impact of his bio-inspired designs. Since 2023, Georgia Tech has filed, or is in the process of filing, utility patents for five of them. Like the RIGA system, those patents will be available for licensing for commercial use. Companies have already contacted Frost about his heat-exchange and geogrid concepts.

“Civil engineering doesn’t traditionally have a culture of patent-producing research,” noted Frost. “It’s exciting to see these filings and how they can generate energy and enthusiasm for studying natural systems and using what we learn to improve the world. Practical application has always been very important to me.”

Frost is finding that practical application also appeals to the next generation of civil engineers — specifically K-12 students interested in the profession who tour the CBID affiliated labs on campus. The students study nature’s designs and figure out how to apply them, rather than learn traditional construction methods.

“Ants, spiders, and worms are immediately relatable for middle- and high-school students,” Frost said. “They think engineering is all math and science, and that doesn’t sound fun to them. Instead, we show them they can be inspired by anything and then use that to make it about conservation and adaptation and energy minimization. Those are things they are interested in.”

Frost is hopeful that the students of today and tomorrow will continue to take inspiration from nature, enabling humans to adapt to a changing world as effectively as nature has.
