Cardinal Pipeline Company, LLC owns and operates an intrastate natural gas transmission pipeline in North Carolina, regulated by the North Carolina Utilities Commission rather than by federal regulators. The line runs about 105 miles of 24 inch pipe from Rockingham County in the north of the state to a point southeast of Raleigh, with a design capacity of roughly 279,000 dekatherms a day. It has no gas supply of its own: it takes gas at an interconnection with the interstate Transcontinental Gas Pipe Line (Transco) system and carries it east to the local distribution companies that serve the Piedmont and Triangle markets. A $39 million system expansion was placed in service in 2012 to add firm transportation for growth on those distribution systems, including a gas fired power station in Wayne County. Its members are subsidiaries of Williams, Piedmont Natural Gas and Public Service Company of North Carolina, the same distributors that take most of its capacity under firm service agreements.
Source
Cardinal Pipeline Company, LLC files nothing with the SEC, so none of this comes from a filer record. The description was written for this site in August 2026 from Duke Energy Form 10-K for the year ended 31 December 2025, Cardinal Pipeline Signs Contracts to Serve North Carolina Natural Gas Growth (PR Newswire) and Piedmont Natural Gas Company Form 10-K (fiscal 2013). The ownership figures below come from the holders' filings instead, and are sourced row by row.
The disclosed stakes
One row per position. Where a holder reports the same company in two share classes, both rows are shown rather than summed, because the class is part of a position's identity.
Where each figure comes from
A private stake has no ownership form behind it, so the source is always the holder's own filing or disclosure. Anything modelled says so, with the arithmetic.

What this page is not
It is not a complete register. It lists the holders who happen to be inside the researched set and disclosed the stake themselves. A private company can have many other shareholders, and nothing here rules them out: venture investors, founders and employees usually appear in no public filing at all. Percentages are of Cardinal Pipeline Company, LLC where a holder stated one, and are missing where no holder did.
