BISMARCK, N.D., Aug. 13, 2025 /PRNewswire/ — MDU Resources Group, Inc. (NYSE: MDU) today announced the election of Charles M. Kelley and Tammy J. Miller to its board of directors, effective Aug. 12, 2025.
Kelley brings more than four decades of experience in the natural gas industry, including a distinguished 25-year career at ONEOK, Inc., where he most recently served as senior vice president of Natural Gas Pipelines. He led strategic growth initiatives and commercial activities for ONEOK’s natural gas pipeline segment, overseeing more than $600 million in capital projects and significantly increasing EBITDA during his tenure. His deep expertise in pipeline development, regulatory strategy, and capital planning is expected to provide valuable insight as MDU Resources’ pipeline subsidiary, WBI Energy, continues to pursue growth opportunities in natural gas transmission and storage.
“I’m honored to join MDU Resources’ board and contribute to the projected growth of its natural gas infrastructure,” said Kelley. “I look forward to supporting the company’s efforts to deliver safe, reliable energy to its customers.”
Miller, a former lieutenant governor of North Dakota, offers a strong combination of executive leadership and public service. She is the former CEO and board chair of Border States, a North Dakota-based electrical distribution company that grew from $485 million to nearly $2.5 billion in annual sales during her tenure. With deep North Dakota roots and a track record of working with utilities and policymakers alike, Miller’s experience aligns well with MDU Resources’ mission and geographic footprint. She currently serves on the board of directors of SkyWater Technology, a publicly traded company, and brings valuable perspectives on public policy, finance, and corporate governance.
Miller commented, “It’s a privilege to serve on the board of a company rooted in North Dakota. I’m excited to help MDU Resources’ mission through my experience in both business and public service.”
In addition to their general responsibilities on the board, Kelley and Miller will each serve on the Audit Committee.
“We’re pleased to welcome Chuck and Tammy to the MDU Resources board,” said Darrel Anderson, chair of the board. “We expect Chuck’s extensive pipeline experience will be a strong asset to our natural gas transmission business, and Tammy’s leadership in both business and government will bring valuable insight as we continue to grow and serve our communities. We look forward to the contributions they will make to our board and our company.”
