Who owns Gulfstream Natural Gas System, L.L.C.

Gulfstream Natural Gas System, L.L.C. - Profile

Gulfstream Natural Gas System operates an interstate natural gas pipeline that carries gas produced in the Gulf Coast region from southern Mobile County, Alabama, across the floor of the Gulf of Mexico and into peninsular Florida, where laterals reach power plants, local distribution companies and municipal utilities. The system runs about 745 miles in total, roughly 419 of them offshore and 294 onshore in Florida, and can move approximately 1.3 billion cubic feet of gas a day. It entered commercial service in 2002 as the first new natural gas pipeline built into Florida in more than forty years, was developed originally by Duke Energy and Williams, and is now held jointly by Williams and Enbridge. Capacity is contracted under long term firm transportation agreements with customers including Florida Power and Light and Duke Energy Florida, and the pipeline has been extended several times through numbered phase projects.

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.

• The Williams Companies, Inc., as of 31 Dec 2025. Equity-method LLC interest, not denominated in shares, so shares is null. FY2025 10-K Note 8 (Investing Activities) equity-method investments table: 'Gulfstream 50% $185 $196' (2025 and 2024 carrying value in millions). The Q2 2026 10-Q reconfirms the 50 percent interest but does not restate an individual Q2 2026 carrying value for Gulfstream, so the FY2025 figure is used. source
