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.

Source: Chattanooga Times Free Press | 2 August 2026 | BY DANIEL DASSOW Nearly 20 years ago, the Tennessee Valley Authority and its main customers -- local electric utilities -- formed a new power company with a specific and unprecedented goal. Seven States Power Corp. , a cooperative owned by the region's local utilities, like EPB in Chattanooga , would co-own power plants with TVA. The cooperative would put ownership of power plants in local hands rather than with the U.S. government, which owns TVA and its assets. Seven States would help the federal agency stay below its $30 billion legal debt limit. From 2008 to 2013, Chattanooga-based Seven States owned a 90% stake in TVA's Southaven gas plant in Mississippi. After TVA lowered its debt and bought Seven States out of the plant, the cooperative pivoted to being a development partner for local utilities as they installed solar panels, electric vehicle charging stations and grid-level batteries. Now, Seven States leadership and members say the group is ready to return to its full founding mission of owning a stake in TVA power plants as the federal utility faces many of the same challenges from two decades ago. (READ MORE: Trump budget does not propose privatizing TVA as utility's debt rises) In a video interview, several managers of utilities in the region said Seven States had an opportunity to help TVA stay under its debt limit and meet higher power demand while keeping assets in local hands. "That original intent has never gone away," said Jeff Dykes, CEO of Johnson City-based utility BrightRidge and chair of the Seven States board. "Even though not a lot of action has happened over the years, it's always come back to that hope and desire and intent. We want TVA to be successful at the end of the day. We need TVA to be successful." Seven States is a generation and transmission cooperative , a model in which utilities band together to form a group that can own power plants. While the model is common in other parts of the U.S., TVA's central authority over its seven-state domain is its own model. "TVA is unique in that it owns the generation, it owns the transmission, it's self-regulating and it regulates its own customers," Wes Kelley, CEO at Huntsville Utilities, said in a video interview. "There's nothing else in the country that fits that paradigm." TVA customers have benefited from the model for more than 90 years, Kelley said, though there is room to integrate best practices from other parts of the country. TVA's debt is expected to rise from $23.8 billion at the beginning of 2026 to $27.3 billion by the end of 2027, according to a recent White House budget. The utility has found ways to offload some of the debt, including by entering lease-purchase agreements. The deals allow TVA to receive payment from a third party in exchange for a master lease on a power plant. TVA continues to own the plant while making payments back to the third party, similar to a mortgage. TVA entered a $2 billion lease agreement in May for its Cumberland gas plant in Middle Tennessee, scheduled for completion by the end of the year. The value of the deals is even greater if Seven States is the third party, said Doug McGowen, CEO of Memphis Light, Gas and Water, TVA's largest customer. Because Seven States is owned by the end customers of the product, its interest in maintaining low power costs is the same as residents of the region. "If Seven States was to take ownership of some of the assets through alternative financing, now you have the customers of TVA who are de facto owners of the assets that are generating the electricity that they are ultimately buying," McGowen said. "For us, that means there is a built-in hedge of protection or inherent checks and balances." Seven States is prepared to finance deals on the magnitude of the Cumberland deal, said Betsey Kirk McCall, CEO of the cooperative. The U.S. Department of Agriculture awarded Seven States $439 million in loans and grants last year, which the cooperative is using to build battery systems for its members. The award made Seven States eligible for greater financing, potentially up to the billions of dollars needed to take stake in a major gas plant, McCall said. Funding agencies include the USDA and the U.S. Department of Energy, she said. "None of them have shied away from numbers and volume of plants that we've put in front of the organizations we've been interacting with," McCall said. Seven States is a "force multiplier" for TVA that acts as an extension of its local power customers for the purpose of increasing power supply, McCall said in a later email. She told the TVA board of directors in May that Seven States had completed 222 projects with 80 utilities and received $475 million in state and federal funds since its founding. At its founding in 2007, the cooperative was designed to issue bonds backed by long-term contracts to purchase power. TVA was building gas plants at the time to meet power demand. The TVA board of directors, the members of which are nominated by the president and confirmed by the Senate, approved negotiations with Seven States in 2008. The move was meant to provide stability in ownership if TVA assets were ever sold by the U.S. government. (READ MORE: Climate groups, senators criticize TVA for fossil gas expansion plans) In the process, Seven States would empower local distributors that operate in a power system where one entity has historically owned and operated all the power plants and transmission lines. "(TVA was) up against the same challenges we're up against today," said Edward Kemp, general manager of Starkville Utilities in Mississippi. "At that time, as well as today, all the local power companies really want to be a part of the solution. We want to help. We're not just depending upon TVA to do everything for us." In 2020, TVA granted its local power companies the ability to generate or buy up to 5% of their electricity. Seven States found a niche in helping local utilities develop their own generating sources, work it continues to do. But as TVA's power demand is rising again after a period in the 2010s marked by flat demand growth, Seven States sees a chance to go big again. The cooperative could once again become a major finance partner to TVA, said Chris Jones, president of the Middle Tennessee Electric Membership Corp. The move would only enhance the public power model that's characterized the region since Congress created TVA during the Great Depression. "It can be even better whenever local power companies are given more priority as a practical partner," Jones said. "I think we're seeing that day come, and Seven States is going to be part of it."

Source: Hoodline | 21 July 2026 | By Bob Norris Memphis Light, Gas & Water is gearing up for a massive battery play that could reshape how Shelby County keeps the lights on and the bills in check. Utility leaders say a new countywide battery storage network could cut pricey wholesale power purchases and help keep electric rates steady well into the next decade. The idea is simple enough, even if the hardware is anything but. MLGW wants large-scale batteries stationed at key substations around the county, ready to kick in when demand spikes and wholesale prices jump. What’s Being Proposed MLGW outlined a plan to install 125 megawatts of battery storage spread across nine substations in Shelby County. The systems would quietly charge up overnight when power is cheaper, then discharge during peak hours to reduce what the utility has to buy from the Tennessee Valley Authority at premium prices. Locations floated by officials include Cordova, Collierville, Whitehaven and North Memphis, according to Action News 5 . It is a far cry from a backup battery in your hallway closet. Project Partners And Funding Regional developer Seven States Power, which is leading the broader Energy Express initiative, is lining up the pieces behind the scenes. The MLGW portion is expected to account for roughly 100 megawatts of a 220-megawatt rollout across Tennessee, supported by about $439 million in zero-interest loans and grants from USDA’s Rural Utilities Service. Seven States Power says construction is scheduled to start in 2027, with a goal of having the full system up and running by December 2028. What City Leaders Were Told Speaking to the Memphis City Council, MLGW President Doug McGowen framed the storage push as a direct play to keep customer bills from climbing. He said the strategy is “designed to push rates downward, down, not up,” and MLGW told council members it does not expect an electric rate increase until after 2030, according to Action News 5 . How This Fits With MLGW’s Earlier Plans This battery push did not come out of nowhere. In March 2025, MLGW issued a request for proposals seeking roughly 100 megawatts of solar generation paired with about 80 megawatts of utility-scale battery storage, along with smaller distribution-level projects. According to MLGW , that RFP let vendors pitch either utility-owned projects or third-party power purchase deals as the utility began testing the waters on local generation and storage. Benefits And Outstanding Questions Seven States estimates the combined battery installations would support power needs for roughly 12,000 homes and create construction jobs along the way. The setup is also expected to limit MLGW’s exposure to the most expensive peak market purchases. But some big pieces still have to fall into place. Siting, permitting and contract details have not been finalized, and the partners say they plan public outreach and technical reviews before any shovels hit the ground, as outlined by Seven States Power . Next steps include more detailed technical studies, regulatory sign-offs, and public briefings before contracts are locked in and crews mobilize in 2027. If the schedule holds, the batteries would be online by December 2028, giving MLGW a new tool to shave peak costs and put continued downward pressure on rates across Shelby County.
