Seven States Power Corporation Expands Team Amidst Substantial Growth
December 7, 2021

Less than one year after Seven States Power Corporation launched as an independent business under the leadership of Betsey Kirk McCall, the trusted energy and technology solutions provider is expanding with the addition of two full-time team members.

Joining the team are Marleen Hamilton and Joe Knox, who bring unique experience to help Seven States deliver industry-leading expertise in electric vehicle charging infrastructure; solar power generation technology; middle-mile fiber connectivity; battery storage; and other game-changing technologies designed to empower the Tennessee Valley’s local power companies to deliver on the promise of safe, reliable, and innovative energy projects.

“As we have defined our brand and built out a portfolio of projects over the past year, we have been blown away by the need for our services,” said Betsey Kirk McCall, President and CEO of Seven States Power Corporation. “The substantial growth we are experiencing affirms the decision our board made less than a year ago to launch Seven States as an independent business. By bringing Marleen and Joe on board, Seven States will be better positioned to support the growing number of projects across the Valley as we continue to serve as the ‘easy button’ for our member-owners.”

Marleen Hamilton joins Seven States as Director of Finance and Accounting. With more than 26 years of corporate accounting experience with both for profit and not for profit organizations, Hamilton is uniquely positioned to lead finance efforts for Seven States. Most recently, she oversaw day-to-day operations for 19 separate entities, with experience in budgeting, cash management, compliance, accounts payable, accounts receivable, balance sheet reconciliations, and audits. Hamilton holds a bachelor of science in accounting from Lee University and resides in Cleveland.

“I could not be more excited to join the Seven States team during this time of explosive growth,” said Marleen Hamilton, Director of Finance and Accounting. “The energy and excitement around the innovative work being done here is palpable, and I look forward to helping the team fulfill its mission as we continue to best serve our member-owners across the Tennessee Valley.”

Licensed professional engineer Joe Knox joins Seven States as Director of Technology Deployment from Knox Consulting Services, a consulting business he started in 2015 to provide technical services to a wide range of clients. His extensive engineering and project management experience will be invaluable as Seven States continues to partner with local power companies to meet the growing demand for technology in the Valley. Knox is a native of Middle Tennessee and graduated from Tennessee Technological University with a bachelor of science degree in civil engineering. He currently resides in Hendersonville with his wife and two children.

“With my extensive background in electrical systems and vehicle fueling technologies, combined with my engineering experience, I am excited to serve local power companies in the Tennessee Valley and assist the team as we execute on the vision for Seven States,” said Joe Knox, Director of Technology Deployment.

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.
