Hardy Storage Company is a West Virginia limited liability company that owns an underground natural gas storage field in Hardy and Hampshire Counties, West Virginia, built by converting a depleted production reservoir and regulated by the Federal Energy Regulatory Commission. Gas is injected in summer and withdrawn in winter for utilities serving the mid Atlantic and southeast, with working capacity of roughly 12 billion cubic feet and peak deliverability that stepped up to about 176,000 dekatherms a day by 2009. The venture pairs a subsidiary of Columbia Gas Transmission, which operates the facility and provides the pipeline connection, with a subsidiary of Piedmont Natural Gas, which became part of Duke Energy in 2016 and subscribes to roughly 40 percent of the capacity. FERC certificated the roughly 100 million dollar project in 2005, first service began in April 2007, and full service levels were reached in April 2009. All of the storage capacity is sold under firm long term service agreements, producing revenue of about 23.5 million dollars in the year to October 2016.
Source
Hardy Storage 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 Piedmont Natural Gas Co., Inc. Form 10-K for FY2016 (SEC), Columbia, Piedmont to Develop New West Virginia Storage Field (NGI) and Hardy Storage Facility Comes On-Line in West Virginia (NGI). 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 Hardy Storage Company, LLC where a holder stated one, and are missing where no holder did.
