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.

PIGEON FORGE, Tenn. — October 3, 2025 — Seven States Power Corporation (Seven States), in partnership with Sevier County Electric System (SCES), and Dollywood is proud to announce the ribbon cutting and official unveiling of 7 new electric vehicle (EV) charging stations with 14 charging ports, and 10 solar-powered umbrella charging units at Dollywood, one of the nation’s leading theme park destinations. The new EV charging stations mark another exciting step forward in advancing transportation infrastructure to support the growing demand for electric vehicles in East Tennessee. Designed, developed, and deployed by Seven States, the project reflects a commitment to innovation, community partnership, and serving Dollywood guests. The ten solar-powered umbrellas will be installed in the Country Fair area, providing guests with a convenient place to charge their devices while they enjoy watching ride goers from the comfort of the shade. “Dollywood is a treasured landmark for families and visitors from across the country,” said Betsey Kirk McCall, President and CEO of Seven States. “We are honored to partner with SCES and Dollywood to deliver technology that adds convenience for guests while enhancing innovation in the region.” The addition of the charging stations and umbrellas highlight the shared vision of Seven States Power and SCES to expand access to energy solutions across the region. SCES provides electric power to more than 61,000 customers across Sevier County, Tennessee. As a locally owned public power utility, SCES has served the community for over 80 years with a focus on reliability, affordability, customer service, and innovation. “These projects represent our commitment to supporting innovation to meet the needs of our community. By working together, we’re helping ensure that both residents and visitors have access to the energy solutions of tomorrow, right here in Sevier County," said Allen Robbins, CEO of SCES. The ribbon cutting ceremony celebrates not only the completion of these projects, but also the growing collaboration between local utilities, community partners, and attractions to create a more modern energy future for Tennessee. “This partnership with Seven States and Sevier County Electric highlights the importance of regional collaboration to build infrastructure that supports both the local community and the millions of visitors to the Great Smoky Mountains each year. By investing in this technology, we are helping pave the way for a more sustainable future, while reinforcing our role as a leader in both the tourism industry and the community we call home," said Eugene Naughton, Dollywood Parks & Resorts President. “These investments further enhance our guest experience by providing services to help meet two emerging needs of those who visit.”  The charging stations will be available for use to patrons in the Preferred Parking Lot of Dollywood Theme Park beginning October 6, 2025 while the umbrellas are available for use immediately.

With his extensive experience in the industry, Kendall Bear’s leadership as General Manager of Rockwood Electric Utility has given him the opportunity to ensure his community is prepared for the future. “Although we’ve had many of the following systems implemented for a few years now, looking back, I would say that building a fiber network between our main office and our substations has been beneficial in a variety of ways for Rockwood Electric. This opened the door for additional technology developments such as AMI, SCADA, distribution automation, Dispatchable Voltage Regulation, a 900 Mhz radio system, and a Meter Data Management System. Implementing a GIS system was extremely valuable as well, as we are now able to export that information to other systems such as Outage Management. We have a business and customer portal from CSA that is used extensively by our employees and customers—everyone really benefits from it.” Kendall knows his LPC is responsible for both the present and future of his community’s needs, and he wants his community to know that he is always looking for ways to better their lives. “We are working very hard to provide a reliable power supply to all our customers and using these different technologies helps us manage the power system. We want to be able to provide real-time information to our customers; something they would not normally have access to without these technologies. I would also want our community to know that we are their ‘trusted energy advisor’ and every employee at Rockwood Electric is committed to helping them make good decisions about the power they use.” With so much technological advancement in the Valley, Kendall encourages fellow leaders to make a strategic plan and collaborate with their peers.  “The possibilities for innovation are almost endless, and there are a variety of products that are offered by many vendors. It is more than a little overwhelming! I would encourage a new GM to develop a strategic plan if the utility doesn’t already have one that is up-to-date. This may involve getting input from the many stakeholders in the community. After prioritizing your goals, get to work. Finally, I would tell a new GM to talk to his or her peers and colleagues a LOT. They will tell you what they have done that has been a colossal flop so you’ll know to avoid it, or they will tell you what they have been successful with. I guarantee every manager will share their story if you ask.”

Marty Ivy knows that when it comes to the energy industry, innovative partnerships and technology help prepare everyone for the unexpected. Leading Mayfield Electric and Water System as General Superintendent, Marty has overcome his community’s fair share of devastating weather events. His experienced leadership has allowed him to place an emphasis on technological diversity and preparedness. We asked him to share his experience with various projects with Seven States: “Most recently, Seven States helped us develop an RFP and select a 1.3-megawatt solar installation that we’re preparing to deploy. Projects like this take time, but once it’s in place, it will serve as our generation to help offset TVA’s requirement. Seven States has also been a major supporter for us in mutual aid during disasters. We’ve had three FEMA events — the remnants of Hurricane Ike in 2008, the ice storm in 2009, and the tornadoes in 2021. So, between disaster recovery and now helping us with solar, Seven States has really been there for us. That’s what makes partnership so valuable — you all make things easier, and we see you not just as partners but as friends who help keep our communities strong. We’re grateful for that support and excited about the projects still to come.” To Marty, the most important thing he wants his members to know is that every decision is made with their needs in mind. “Mayfield Electric and Water System strives to be an efficient and innovative utility while managing both reliability and rates. That’s really what it comes down to — being reliable and keeping costs low for our customers. We’ve already seen how innovation can transform our operations. For example, our customer service representatives have been amazed at how much new technology has improved our outage management system. It’s made responding to customers easier, faster, and far more efficient, especially during storms. There’s so much potential we haven’t even discovered yet in the Valley.” With 34 years of industry experience, Marty knows that change is inevitable. He offered this advice to general managers who might be wondering where to start when it comes to bringing innovation to their LPC. “The best advice I can give anyone is this: you can’t effectively manage what you don’t know. That’s why technology is so important — it puts knowledge of your system right at your fingertips. My advice is, don’t be afraid of change. I’ve been with Mayfield Electric and Water System for 34 years, serving as manager since 2001. Over that time, I’ve seen the industry cycle and evolve about every five years. The one constant is that change always comes, and if you’re afraid of it, you’ll get left behind. So, for future managers and anyone in this industry, my advice is to dive in, get your feet wet, and embrace the changes that move us forward.”
