Who owns Roadrunner Gas Transmission Holdings, LLC

Roadrunner Gas Transmission Holdings, LLC - Profile

Roadrunner Gas Transmission is the holding vehicle for a bidirectional interstate natural gas pipeline that carries Permian Basin gas from West Texas to the Mexican border. The line runs roughly 200 miles of 30 inch pipe from the ONEOK WesTex Transmission system at Coyanosa, Texas, west to an international crossing near San Elizario, Texas, where it ties into Fermaca's Tarahumara Gas Pipeline for onward delivery into northern and central Mexico. Built in phases from 2016, it can move up to 640 million cubic feet per day, of which up to 570 million cubic feet per day is destined for Mexican markets, and its capacity was contracted under long term take or pay transportation agreements with Mexico's state electricity utility CFE and with Fermaca. The venture pairs ONEOK, which supplies the Texas gathering and transmission connection and operates the pipeline, with Fermaca Infrastructure of Mexico City, which supplies the downstream Mexican pipeline network.

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.
