Rockies Express Pipeline (REX)

Click to see larger, detailed image Rockies Express Pipeline LLC (REX) is one of the largest pipelines ever constructed in the United States. The 1,698-mile pipeline stretches from northwestern Colorado and Wyoming to eastern Ohio and boasts 1.8 billion cubic feet per day of long-haul design capacity. REX became fully operational in November 2009.

In addition to providing an outlet for Rockies gas production, the pipeline has recently begun firm service from Appalachian basins to Midwest markets. In particular, Rockies Express is developing firm, bi-directional capability in its rate Zone 3 between Ohio and Illinois. As a consequence, Midwest markets (including local distribution companies, industrial customers, power plants, and third party pipelines) will have access to abundant natural gas sources in the Rockies and Appalachian basins. This supply optionality should benefit consumers in terms of pricing and reliability.

Rockies Express is owned by Tallgrass Development (through a subsidiary, Tallgrass Development owns a 50 percent interest in and operates the pipeline), Sempra US Gas & Power and Phillips 66.
