TN Clean Fuels Press Release: Tennessee Tech Unveils New DCFC Unit in Cookeville as Part of “EV Testbed” Project
July 29, 2020

On July 22,  Tennessee Technological University  (Tennessee Tech, or TTU) unveiled a new  Direct Current Fast Charging  (DCFC) station that will serve a  U.S. Department of Energy -funded project started in 2019, as well as the greater Cookeville area. The unit was installed in a TTU parking lot along a busy corridor in Cookeville and will be the primary refueling site for an all-electric E450 shuttle bus that is part of the same DOE project. Lead project infrastructure partner  Seven States Power Corporation  managed the installation.

TTU was awarded and started that three-year DOE project last year, towards “developing an Electrical Vehicle (EV) Testbed in the 14-county ‘Upper Cumberland’ region of Tennessee.” The region is a largely rural area and includes a number of economically distressed counties (see map below). The grant’s Principal Investigator,  Dr. Pingen Chen , is an Assistant Professor in TTU’s Department of Mechanical Engineering and has brought a diverse group of about 10 partners into the project.

One component of this multifaceted project is the installation of nine EV charging units throughout the Upper Cumberland region. The first of the nine EV charging units is the DCFC unit that was installed at  320 University Drive, Cookeville, TN 38501. In the coming months, the remaining eight EV charging stations – all of which will be Level-2 stations – will be installed in select locations in the surrounding counties in the following cities:  Lafayette, Carthage, Livingston, Byrdstown, Jamestown, Smithville, Sparta and Spencer.

The 14-county region in the project is along the Cumberland Plateau and in the central part of Tennessee, and has Cookeville as its largest city with a population of just over 35,000.

Combined, they will produce the beginnings of a charging network for the entire region that has largely had no focused EV-development efforts within it to date. Once the project is completed, it will have produced a “proof of concept roadmap” for how other rural areas across the U.S. can follow suit and help accelerate their development of EV charging and growth in use.

Another facet of the project includes procuring five electrified vehicles, which include three  Nissan Leafs , one all-electric E-450 passenger shuttle, and one plug-in hybrid F-250. “The three Nissan Leafs are ready to be used now for educational purposes, such as showcasing the value of electric vehicles through Ride and Drive or Show and Tell types of experiences specifically for our rural community,” said Dr. Chen. “Many times, in our state, we see plenty of EV opportunities and accessibility available in metropolitan cities, whereas rural communities are not prioritized. Our goal is to provide information, education, and a variety of EV experiences and opportunities for business leaders and community members to have access to this new automobile technology and to help inform their buying decisions.”

Also, in attendance at the DCFC unveiling was TTU’s President, Dr. Phillip Oldham. “We are pleased with Dr. Chen’s EV initiative at TTU. This project fits well within TTU’s Grand Challenge Initiative called  Rural Reimagined which focuses on how the university will harness science, technology, and innovation to transform rural living,” said President Oldham. “Tennessee Tech serves more distressed counties than any other state university in Tennessee and is centrally located to eight counties in great need. We have an opportunity where this EV initiative can drive change through developing partnerships that will help transform our rural community. We find this opportunity energizing and a step-forward for Tech and our community overall.”

While the Nissan Leafs will be utilized to showcase EV operations and driving ease to individuals and fleets in the entire region, the E-450 shuttle will be used specifically by the transportation department of the Upper Cumberland Human Resource Agency. They plan to first utilize a TTU and downtown Cookeville route to operate the shuttle, but after any initial problems are worked out and the shuttle has proven its reliability in service, the department plans to move it to other routes around the 14-county region. Finally, the plug-in hybrid F-250 was specifically chosen as ‘best choice’ for getting farmers in the counties to test drive an electric vehicle. Jonathan Overly of ETCleanFuels notes, “if we really wanted to change the region’s farmers opinions about EVs, we thought that range restriction could make them test driving an EV a nonstarter. Thus, we elected to go with a plug-in hybrid so that they could finish any chore or task that they might handle on any given day.” The three Leafs are already in use, while the E-450 and F-250 are still in the process of being converted by those respective partners, Phoenix Motorcars and XL Fleet.

 

TTU’s project includes partnerships with  Nissan North America , the  East Tennessee Clean Fuels CoalitionChargePointSeven States Power Corporation , the  Upper Cumberland Human Resource Agency , the  University of Texas at AustinPhoenix MotorcarsLyft  and  Oak Ridge National Laboratory.

It’s easy to forget that the excitement of a potential “snow day” is not shared by everyone. Winter storms are felt differently depending on where you stand. When news of Winter Storm Fern first began to circulate, many of us debated whether it would amount to much at all—whether we’d “actually get any snow,” or whether the warnings would quietly fade away. For our local power companies (LPCs), though, there is no room for debate. Preparation begins long before the first snowflake falls. Crews mobilize. Capacity is recruited. Logistics are coordinated—meals, lodging, equipment—on the assumption that the storm will come, and that its impact could be catastrophic for the communities they serve. As Winter Storm Fern made her way across the Tennessee Valley, what unfolded in the weeks that followed was nothing short of remarkable. The storm itself was a spectacle – both terrifying and beautiful. In its aftermath, we saw images of deep snowbanks, children sledding, and intricate ice formations clinging to trees and fences. But those of us in the energy industry understand the other side of that beauty—the weight of ice on lines, the strain on equipment, and the fragile balance that keeps electricity flowing. Once again, we were reminded that society moves at the pace of electricity. In the days after the storm passed, we witnessed something even more powerful than the weather itself: the best of our humanity. The people we are proud to work alongside woke up day after day, coffee in hand and hot stick over their shoulder, ready to face whatever challenge waited beyond the truck door—all so that power, and a sense of order, could be restored. Was the work harder than expected? Probably. Did it reaffirm what it means to put service above self? Without question. While many of us remained sheltered at home, LPC crews from across the Valley stepped up. They melted the storm inch by inch, knocking ice from lines and equipment so electricity could move again without the crushing weight pulling it back down. They followed the sound of silence, tracing outages through snow-buried lines until they found a snapped conductor lying quiet in a ditch. Bucket trucks crept through ice-locked streets, their booms lifting linemen into sleet-soaked darkness to replace shattered crossarms and transformers split by the cold. The grid returned not all at once, but by touch—each repaired connection passed hand to hand through crews spread across miles of frozen ground.  As Mike Partin, President of the National Rural Electric Cooperative Association (NRECA) and President & CEO of Sequachee Valley Electric Coop, recently shared, “It’s more than a principle on paper—it’s a promise we live out when disaster strikes. These men and women leave their own families to help other families. They go wherever they’re needed, whenever they’re needed, without hesitation.” And they were not alone. Businesses across the region stepped in as well, delivering hot meals—Taco Bell, Chick-fil-A, the unmistakable fuel of long days and longer nights. Electricity and kindness—two commodities that can feel in short supply—were both restored through collective effort. Moments like these force us to pause and reflect on the grit, resilience, and stamina that make our communities strong. Sometimes, Mother Nature reminds us not only of our vulnerabilities, but of our better angels. Today, homes are warm. Restaurants are open. Kids are back in school. Life has returned to something resembling normalcy—because of the unity, sacrifice, and hard work of LPCs across the Tennessee Valley. So we wanted to take a moment to simply say: Thank you.

Seven States continues to deploy battery energy storage system (BESS) projects and advance regional infrastructure initiatives. Recent projects—including the Montgomery Bell State Park (MBSP) installation—have provided valuable lessons that are shaping our approach moving forward. From operational insights to market signals, these experiences are informing how we deliver value to our member utilities. 1. Experience Our experience at MBSP confirmed that integrating battery storage into existing electric systems is well within current technical capabilities. The greater challenge lies in managing the additional workload alongside the daily priorities of utilities. Capturing lessons learned with each installation and applying them at scale to future projects allows each deployment to benefit from the last by reducing costs and increasing speed. 2. Performance tracks expectations To date, system performance at MBSP has been reliable, with no material operational issues. Financial results are also aligning with projections, reinforcing confidence in the technology itself. The primary risk areas are: forecasting peak demand and scheduling dispatch accurately to capture expected value—an operational nuance that becomes increasingly important as storage portfolios grow. Demand reduction assets are best served to be installed at reliable grid locations, which tend to be distribution substations, to minimize operational downtime due to extrinsic factors. 3. Integration impacts performance While standalone battery controllers can manage basic operations, deeper system integration delivers meaningful benefits. In particular, SCADA integration can significantly reduce the risk of missing peak events by improving visibility and responsiveness. This lesson is informing how Seven States designs future BESS projects, ensuring storage assets are fully integrated into utility operations rather than standalone resources. 4. Interest in BESS is growing Across the region, the market for battery storage and Reliability as a Service is shifting from early skepticism to informed curiosity. Utility interest continues to rise, though many are waiting for greater clarity before moving forward. Key sources of hesitation include uncertainty around TVA rates, evolving TVA programs, and open questions related to federal tariffs and tax policy. As these issues come into focus, we expect interest to translate into action. Together, these takeaways are guiding Seven States as we advance upcoming BESS projects and broader infrastructure initiatives. By applying proven lessons, prioritizing integration, and maintaining a regional focus, we are building a more resilient and flexible energy future for the communities we serve.

Chattanooga Times Free Press | 15 Feb 2026 | BY SEVEN STATES POWER CORPORATION BOARD OF DIRECTORS Demand for energy is climbing while extreme weather events like Winter Storm Fern and Winter Storm Elliott continue to challenge an already constrained electric system. Fortunately, there is a ready-now solution. Seven States Power Corporation is a cooperative designed to help meet demand for affordable, abundant and reliable power. Since the 1930s, the Tennessee River Valley has thrived under a vital network of the wholesale power provider — the Tennessee Valley Authority — and the electric utility customers that together form the public power model. More than 150 electric utility customers distribute affordable energy across a seven-state region of Tennessee, Alabama, Georgia, Mississippi, Kentucky, Virginia and North Carolina. In 2007, TVA and the electric utilities joined forces to form Seven States as an in-valley solution to finance power assets, expand energy production and modernize infrastructure. THE ‘IN-VALLEY’ SOLUTION Seven States is a nonprofit generation and transmission cooperative headquartered in Chattanooga. It is member-owned by the electric utility customers of TVA across the seven-state region. The cooperative is uniquely positioned to operate outside established debt constraints and regulatory limitations that restrict other entities. This means Seven States can own large power plants and transmission towers, which frees up debt for TVA to build and operate more power supply. When the electric utility customers collectively own assets through Seven States, it also ensures that rates in the region remain affordable. This flexibility allows Seven States to move quickly to supplement the valley’s energy needs with reliable sources of power. In January 2025, Seven States was awarded $439 million by the U.S. Department of Agriculture, consisting of a zero-interest loan and grant to build new capacity. The first initiative under this award is a utility-scale power project that will enhance grid stability and reliability, benefits that can be shared across the valley. Where demand for capital and power are soaring, Seven States makes it happen. Seven States has a proven history of filling critical gaps when needed. One of its earliest projects with TVA was financing a large power asset — an 800-megawatt gas plant located in Southaven, Mississippi. By partnering with Seven States, the energy sector can nearly double its capital investment to accelerate generation projects. Where finances are constrained, Seven States makes it happen. In addition, Seven States has stepped up to deliver distribution technologies that bridge the past, present and future of a modern energy grid. With projects deployed across the valley at the U.S. Space & Rocket Center in Huntsville, Alabama, Dollywood Parks and Resorts in Pigeon Forge, Montgomery Bell State Park in Burns, Tennessee, Rock City in Lookout Mountain, Georgia, and the National Corvette Museum in Bowling Green, Kentucky, and with more than 500 electric vehicle chargers installed to date, Seven States has proactively advanced infrastructure to support economic development across the region. Where innovation and infrastructure are needed, Seven States makes it happen. In July 2025, the Seven States Board of Directors — representing 17 major electric utilities that purchase power from TVA — unanimously passed a resolution affirming Seven States as an additional supplier of abundant, reliable energy within the valley. By advancing an in-valley solution owned by the customers, the public power model can thrive and evolve from within, guided by those who know the region best. Seven States has built a foundation for the energy future through its cooperative structure and access to affordable capital. It represents a real opportunity to expand power production and light the way for prosperity across the Valley.
