Atlantic Coast Pipeline, LLC - Profile

Type
joint venture
Based in
United States
Founded
2014

Atlantic Coast Pipeline, LLC was the joint venture set up in 2014 by Dominion Energy and Duke Energy, with Southern Company Gas also taking a stake, to build and operate a roughly 600 mile underground natural gas transmission line running from the Marcellus and Utica shale fields in West Virginia across Virginia and into eastern North Carolina. The line was intended to feed gas fired power stations, local distribution utilities, military installations and industrial customers in a region the partners argued lacked supply diversity. Costs rose from an initial 4.5 to 5.0 billion dollars to about 8 billion, and after a Montana court decision vacated the Nationwide Permit 12 water crossing authorisation and a Ninth Circuit ruling made a successful appeal unlikely, the partners cancelled the project on 5 July 2020 without the pipeline ever entering service.

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 Atlantic Coast Pipeline, LLC where a holder stated one, and are missing where no holder did.
