New Research Includes Integration of Batteries
May 13, 2020

Battery storage. It isn’t typically something to get powered up about, but as the Seven States Power team recently discovered, there are some exceptions.

Our team recently received three 13.5 kwh batteries from EPB in Chattanooga for use in our Smart Grid Lab and installed one on each phase of electrical service at our headquarters.

“Most energy storage providers are focused on large grid-scale batteries or small residential batteries. We’re interested in understanding energy storage for our many small and medium businesses,” explained Lance Irwin, EPB’s Director of Energy Solutions Technology. “Seven States Power’s Smart Grid Lab is a great opportunity for our vendors and other LPC’s to learn from a real-world application.”

The units are flat, wall-mounted lithium-ion batteries that store electricity for solar self-consumption, time of use load shifting, backup power, and off-the-grid use. The modular system offers the flexibility to add multiple batteries for homes or businesses with high energy demands. Part of the testing with the manufacturer is a new load forecasting function that will automatically dispatch the batteries for optimal cost savings based on the building load and the electricity rates.

“In our laboratory, we will test how the batteries work, how well they perform, and how these batteries compare to other products on the market,” said Steve Noe, director of strategic energy solutions. “Battery storage will be an integral part of microgrids in the future, so we’re particularly interested in how it combines with technologies that could be used as a microgrid and how well it integrates into the DER Management System (DERMS).”

Our load management simulation laboratory is designed to integrate technologies that could benefit our members, show how DERMS software works in real time, and to explore the capability it offers those seeking to manage costs by filling valleys and shaving peaks.

The next phase of our Smart Grid Lab development includes the addition of load forecasting capabilities and controllable lighting.

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.
