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 Coalition ,  ChargePoint ,  Seven States Power Corporation , the  Upper Cumberland Human Resource Agency , the  University of Texas at Austin ,  Phoenix Motorcars ,  Lyft  and  Oak Ridge National Laboratory.

Valley Update: Tennessee Valley Corridor & USDA

By Jessica Bradshaw • April 7, 2026
Seven States Power Corporation President and CEO, Betsey Kirk McCall, attended the Tennessee Valley Corridor (TVC) Board of Directors meeting in Washington, DC on March 4, 2026, joining regional leaders to discuss economic development, infrastructure investment, and the TVC’s upcoming National Summit. The TVC brings together stakeholders from government, industry, and academia to strengthen the region’s competitiveness and support long-term growth. McCall’s participation reinforced Seven States’ commitment to collaborating with regional partners to ensure the Valley’s energy systems continue to support economic expansion and community prosperity. During this visit, McCall also met with the U.S. Department of Agriculture's Rural Utilities Service staff to discuss additional federal financing opportunities that could support energy development across the Tennessee Valley. The conversation focused on Seven States’ request for nearly $6 billion in funding to acquire natural gas generation resources across the Valley. An additional $320 million could support distribution-scale Battery Energy Storage Systems (BESS), helping utilities strengthen grid reliability and modernization of the region’s power infrastructure. By strengthening relationships with federal leaders and advocating for policies that support growing energy demands in the Valley, McCall reinforced Seven States’ commitment to reliable, affordable and abundant power supply. McCall plans to attend the TVC's National Summit on May 28-29, 2026 in Chattanooga, TN to highlight the region's growth for economic prosperity.

State Update: Advocacy at the Tennessee State Capitol

By Jessica Bradshaw • April 7, 2026
Seven States President & CEO, Betsey Kirk McCall, spent time at the Tennessee State Capitol on February 4, 2026, meeting with legislators including members of the Senate Energy, Agriculture and Natural Resources Committee, and the House Commerce Committee. A central focus of the meetings was providing an update on Seven States’ Energy Express project, an initiative designed to support growth in the Tennessee Valley with 220MW of battery storage. This project will be funded with a $439 million award by the U.S. Department of Agriculture’s Rural Utilities Service (USDA RUS) New ERA program. McCall shared how Seven States will leverage federal financing opportunities, such as their USDA award of $439 million along with access to additional federal funds, to build or acquire generation and capacity to meet energy demand across the region, particularly as TVA navigates its debt constraints. She updated the legislators on how funding available to Seven States complements and amplifies TVA’s efforts to maintain a reliable energy system. By pairing federal financing with regional expertise in project deployment, Seven States can help utilities of all sizes move energy projects forward. The Seven States team also successfully engaged in state-level advocacy efforts to help stop proposed legislation that would have imposed an additional tax on electric vehicle (EV) charging. Working alongside partners and stakeholders, Seven States communicated to lawmakers how the proposed tax could create unnecessary barriers to EV infrastructure development and slow innovation within Tennessee’s evolving energy and transportation sectors. These advocacy efforts serve to refine and advance initiatives that impact a rapidly changing energy landscape. Together with partner LPCs, Seven States is building and energizing the grid of the future.

Federal Update: APPA Legislative Rally

By Jessica Bradshaw • April 7, 2026
Seven States Power Leadership traveled to Washington, D.C., February 23–25 to meet with members of the Tennessee Valley congressional delegation while attending the American Public Power Association (APPA) Legislative Rally with the nation’s public power electric utilities. Seven States Board Chair, Jeff Dykes, (CEO, BrightRidge) and President & CEO, Betsey Kirk McCall engaged with federal leaders to advocate for more power supply, educate on the flexible financing available to Seven States as a generation and transmission cooperative, and build relationships with federal representatives on key energy issues. A central focus of the meetings was providing an update on Seven States’ Energy Express project, an initiative designed to support growth in the Tennessee Valley with 220MW of additional capacity. This project will be funded with a $439 million award by the U.S. Department of Agriculture's Rural Utilities Service. McCall and Dykes also led discussions highlighting how Seven States serves as an in-Valley solution to the Tennessee Valley Authority’s current debt constraint challenges. Through its financing capabilities, Seven States can own utility-scale power plants and double the impact of TVA’s capital investments, thereby expanding production and modernizing grid infrastructure. McCall and Dykes worked to educate policymakers about how aligning objectives and encouraging the use of Seven States as a mechanism for short- and mid-term financing solutions can unleash American energy faster. McCall plans to attend the NRECA Legislative Conference April 26 – 28 in Washington D.C. to continue these efforts with the nation’s electric cooperatives.
