Battery Storage Is Charging Up
January 23, 2023

The Tennessee Valley has an opportunity to lead the nation in battery storage technology .  As its members, the Local Power Companies (LPCs), explore battery storage options, Seven States is the go-to partner to streamline the process, aggregate projects for grant funding, and facilitate a successful deployment. Seven States has broad experience building partnerships to deploy a variety of different storage technologies, including at the US Space and Rocket Center , the University of Memphis , and Nissan’s manufacturing plant in Smyrna, TN.

Through their work with battery storage, LPCs continue to explore how this technology can enhance the reliability, resiliency, affordability, and sustainability of their operations.  For example, battery storage units can be dispatched effectively during valley-fill generation periods and provide high confidence generation for day-ahead programs that complement demand response programs. Reducing the monthly on-peak and all-peak demand can save an LPC more than $10 for each kW reduced. Understanding typical monthly load curves and strategically deploying battery storage units are key to optimizing this untapped opportunity.

Additionally, battery storage allows for end-of-line voltage support and serves as a core generation source for a microgrid. In other parts of the US, battery storage is used to provide ancillary transmission support services.

True to its purpose as a hub for innovation and information sharing, Seven States released two RFIs in 2022 to study the battery storage market. The results revealed two primary approaches to pricing for LPCs: leasing or owning. While leasing costs over the life of the project are expected to be higher than if the LPC purchases the system directly, it allows the LPC to minimize risk.  Direct ownership may yield lower costs; however, the LPC assumes operational risk.

In 2022, the battery storage market experienced unprecedented demand as well as unprecedented supply issues with core materials associated with lithium batteries. Battery prices increased by 7% in 2022, according to a recent Bloomberg report. Several utility battery manufacturers are switching to lithium iron phosphate (LFP) batteries because core materials are available and less expensive. As this transition continues and new battery manufacturing plants open in the US, prices are expected to levelize.

The Inflation Reduction Act of 2022 (IRA) provided new tax incentives for battery storage both by expanding the number of entities who are eligible and by raising the maximum potential savings percentages.

State and local governments (and political subdivisions thereof) are now eligible to receive the investment tax credit (ITC). Standalone battery storage projects are now eligible for ITCs (previously, battery storage was not eligible for the ITC unless it was tied to a solar array). The legislation also raised the maximum ITC rate from 26% to 30% — with some projects now even eligible to receive up to 50% in credit if the project meets additional requirements.

Federal tax incentives and market forces are combining to make battery storage solutions a better bet for LPCs in the Valley. If you want to learn more about battery storage for your LPC, give Seven States a call.

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.”
