Four Key Takeaways from Seven States' Recent Energy Deployments
February 18, 2026

Seven States continues to deploy battery energy storage system (BESS) projects and advance regional infrastructure initiatives. Recent projects—including the Montgomery Bell State Park (MBSP) installation—have provided valuable lessons that are shaping our approach moving forward. From operational insights to market signals, these experiences are informing how we deliver value to our member utilities.


1. Experience
Our experience at MBSP confirmed that integrating battery storage into existing electric systems is well within current technical capabilities. The greater challenge lies in managing the additional workload alongside the daily priorities of utilities. Capturing lessons learned with each installation and applying them at scale to future projects allows each deployment to benefit from the last by reducing costs and increasing speed. 


2. Performance tracks expectations
To date, system performance at MBSP has been reliable, with no material operational issues. Financial results are also aligning with projections, reinforcing confidence in the technology itself. The primary risk areas are: forecasting peak demand and scheduling dispatch accurately to capture expected value—an operational nuance that becomes increasingly important as storage portfolios grow. Demand reduction assets are best served to be installed at reliable grid locations, which tend to be distribution substations, to minimize operational downtime due to extrinsic factors.


3. Integration impacts performance
While standalone battery controllers can manage basic operations, deeper system integration delivers meaningful benefits. In particular, SCADA integration can significantly reduce the risk of missing peak events by improving visibility and responsiveness. This lesson is informing how Seven States designs future BESS projects, ensuring storage assets are fully integrated into utility operations rather than standalone resources.


4. Interest in BESS is growing
Across the region, the market for battery storage and Reliability as a Service is shifting from early skepticism to informed curiosity. Utility interest continues to rise, though many are waiting for greater clarity before moving forward. Key sources of hesitation include uncertainty around TVA rates, evolving TVA programs, and open questions related to federal tariffs and tax policy. As these issues come into focus, we expect interest to translate into action. 


Together, these takeaways are guiding Seven States as we advance upcoming BESS projects and broader infrastructure initiatives. By applying proven lessons, prioritizing integration, and maintaining a regional focus, we are building a more resilient and flexible energy future for the communities we serve.

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.

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.

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.
