Duke Energy completes sale of its Tennessee Piedmont Natural Gas business to Spire
- Close of transaction previously announced in July 2025
- Proceeds to help fund industry's largest regulated capital plan
CHARLOTTE, N.C., March 31, 2026 /PRNewswire/ -- Duke Energy (NYSE:DUK) today announced it has completed the sale of its Tennessee Piedmont Natural Gas business to Spire – one of the largest publicly traded natural gas companies in the country – for $2.48 billion. The agreement was previously announced on July 29, 2025.
Approximately $800 million of the proceeds will be used to pay down debt at Piedmont Natural Gas to maintain its capital structure. The remaining $1.5 billion proceeds, net of tax, will help efficiently fund the industry's largest regulated capital plan – $103 billion of investments over the next five years – to support a growing system and serve increasing load while keeping customer costs as low as possible.
"Today marks a significant milestone with the successful transition of our Tennessee natural gas business to Spire," said Harry Sideris, Duke Energy president and chief executive officer. "As we enter a period of record investment, this transaction helps efficiently fund our capital plan – a plan built on safely and reliably meeting our communities' growing energy needs while managing costs for our more than 10 million customers."
Sideris added, "I want to thank our Tennessee natural gas teammates for their commitment to industry-leading customer service, safety and operational excellence, as well as the Nashville community for trusting us to serve its growing energy needs for more than 40 years. Spire will carry forward best-in-class service and continue delivering value for Tennessee employees, customers and communities."
"We're pleased to welcome Piedmont customers and employees in Tennessee to Spire," said Scott Doyle, president and chief executive officer of Spire. "This acquisition allows us to expand our core utility business while continuing to do what we do best as a company – safely delivering reliable natural gas to the communities we serve."
The sale agreement for the Piedmont Natural Gas Tennessee business included nearly 3,800 miles of distribution and transmission pipelines serving more than 200,000 customers. The primary operations will remain in the Greater Nashville area, and the Piedmont Natural Gas employees who primarily support the business have transitioned to Spire to maintain business continuity for its operations and customers.
