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.

Seven States Power Corporation’s Board Chairman, Jeff Dykes, and President & CEO, Betsey Kirk McCall, met with Congressional leaders earlier this summer as part of a strategic initiative to advance funding to install technologies that make power more efficient, reliable, and abundant. Dykes and McCall sought to amplify the need for greater federal support to Tennessee Valley LPCs for increasing America’s energy infrastructure during a time where creative options are needed against the backdrop of unprecedented growth. A primary objective of the trip was to listen to legislators’ areas of focus and educate the leaders on how Seven States supports the Valley through times of transition. Many LPCs have voiced concerns over the volume of requests they are receiving to supply energy to data centers. Dykes and McCall emphasized the opportunities Investment Tax Credits (ITC) and alternative financing provide for accelerating large-scale projects that can supply this growing demand for energy. To date, more than 1200 data centers are in development across the U.S. that will consume an estimated 149.6 -239.3 TWH annually. That represents the equivalent of 15-25 large nuclear plants running continuously to supply the need. Dykes and McCall stressed how cooperatives like Seven States can leverage funding models that alleviate the capital outlays for and accelerate construction of projects that can accommodate the expected growth in the Valley over the next decade from these data centers. “It will take LPCs, TVA, communities, companies, and developers working together on such projects to meet the need and keep the lights on,” said Dykes. “We understand that these data centers represent an opportunity for investment in the region. These dollars will improve communities and attract high quality economic development prospects. We want to ensure our member LPCs and TVA are supported and prepared to deliver this opportunity to the Valley,” said McCall. Dykes and McCall also underscored that Seven States was created by LPCs, in partnership with TVA, as a strategic solution to TVA’s debt ceiling limitations—without amending the TVA Act. From 2007 to 2013, Seven States became the first —and remains the only— LPC-led organization to successfully negotiate a sale/leaseback agreement with TVA to co-own a utility-scale generation asset: the Southaven 800MW Combined Cycle Gas Plant. This makes Seven States uniquely qualified as an in-Valley solution to finance and co-own generation assets with TVA.  “Seven States was created for moments like this. We often serve as the designer or developer, deploying capital and project management expertise to build reliable or advanced energy infrastructure on behalf of LPCs. This allows LPCs to avoid the burden of raising capital or navigating complex regulatory issues,” said McCall. Another key focus of the trip was to share project updates on the $439 million in funding secured earlier this year through the U.S. Department of Agriculture’s New ERA program. Dykes and McCall outlined how this investment will be used to deliver 250MWs of additional power—aligning with national priorities on energy dominance and security. While in Washington, the team also met directly with USDA officials to provide a progress report on the project. “We are at a pivotal moment where federal partnerships can accelerate the progress our members are already making,” McCall said. “Our goal is to ensure their contributions—and their challenges—are clearly understood as Congress shapes the future of energy policy.” More recently, McCall was also in the area conducting meetings during President Trump’s One Big Beautiful Bill event where Zach Stewart of Sequachee Valley Electric Cooperative was among those recognized for their service to the nation in the energy industry. McCall was on site as the new Rural Utilities Services Administrator at USDA, Karl Elmshaeuser, was announced. McCall met with Christopher McClean, former Acting RUS Administrator as part of a series of meetings to further map project details related to the $439 million awarded to Seven States by USDA. By engaging directly with lawmakers and federal agencies, Dykes and McCall are working to ensure that regulatory frameworks reflect on-the-ground realities. These Washington outreach efforts reinforce Seven States’ commitment to building an energy system that is affordable, reliable, and future-focused. Dykes and McCall expect continued conversations throughout the year as the Valley’s energy future takes shape.

Seven States recently had the privilege of partnering with the Chattanooga Area Food Bank to provide consulting support for energy efficiency upgrades at their main distribution facility. Serving 20 counties across Southeast Tennessee and Northwest Georgia, the Food Bank distributed over 15 million pounds of food last year—equivalent to more than 12 million meals for families in need. With such a vital and energy-intensive operation, improving energy performance means more resources can go directly toward feeding the region. Our team conducted a comprehensive energy assessment, identifying key opportunities to reduce utility costs through more efficient lighting, refrigeration, and HVAC systems. These recommendations are expected to cut energy use by up to 25%, translating into substantial cost savings over time. By optimizing energy performance, the Chattanooga Area Food Bank can reinvest those savings into expanding food access, enhancing logistics, and continuing their mission to eliminate hunger and promote healthier communities.  This collaboration not only underscores the connection between energy efficiency and social good, but also highlights how thoughtful upgrades can deliver lasting value for mission-driven organizations. We're proud to support the Food Bank’s critical work and look forward to seeing the positive ripple effects of this project across the communities they serve.

Leading Forked Deer Electric Cooperative as General Manager & CEO, Jeff Newman has firsthand knowledge of how vital technology is to the Valley and what a difference it has made in his community. “In our footprint, two of the most critical technology developments were broadband expansion and system automation. Bringing our system up-to-date has been a top priority, and that started with implementing SCADA across the network—a process that’s still ongoing. SCADA has already made a significant difference by improving our ability to detect and respond to outages quickly, which greatly reduces downtime for our members. On the broadband side, we now serve over 6,800 folks, which represents a substantial portion of our total meters. In a rural area like ours, access to high-speed internet isn’t just a convenience, it’s a necessity. It’s been a game changer, and the revenue from broadband has helped stabilize our electric rates by offsetting the need for larger increases. So, these technology developments haven’t just modernized our infrastructure—they’ve directly improved quality of life and economic resilience for the people we serve.” As the Valley continues to evolve and technology changes, Jeff views Seven States as a trusted partner that can help LPCs find the best fit for their community. “The biggest thing for us, as a rural utility, was having someone to help us get connected with the right people—whether that’s suppliers, vendors, or experts. We really leaned on Seven States for that support because, honestly, we didn’t even know where to begin. Every utility is different, and there’s no one-size-fits-all solution. You have to do what makes sense for your system and your community. A cookie-cutter approach just doesn’t work in this industry, and Seven States knows how to tailor a project or service to fit your exact needs.” Jeff’s advice to GMs who want to bring innovation to their communities is to stay open to progress by listening, learning, and ensuring new ideas truly serve the needs of the ratepayers. “I don’t take credit for the changes we’ve made, but progress happens when you don’t stand in its way. It’s important to evaluate new ideas carefully, make sure they align with your system’s needs, and support what makes sense. The key is to always consider what’s best for your LPC or co-op—and not become an obstacle to improvement.” ###
