The Rockies Express Pipeline has undergone significant expansion and capacity upgrades over the years. It now stretches over 1,700 miles from the Rocky Mountains to the Midwest.

In 2011, the pipeline's capacity was increased by 25% to 1.98 billion cubic feet per day. This upgrade enabled the pipeline to transport more natural gas to meet growing demand.

The expansion and upgrade have helped to improve the pipeline's efficiency and reliability. It has also enabled the pipeline to transport more gas from the Marcellus and Utica shale regions.

Technical Details

The Rockies Express Pipeline is a massive infrastructure project that spans over 1,679 miles. The pipeline's diameter varies between 36 and 42 inches, with the majority being 42 inches.

The pipeline's capacity is impressive, with the ability to transport 3.6 billion cubic feet of natural gas per day, or 37 billion cubic meters per annum. It operates at a maximum allowable pressure of 1,480 pounds per square inch.

The initial cost of the pipeline was around US$5 billion, making it a significant investment in the energy infrastructure of the United States.

Pipeline Zone 3 Capacity Upgrade is a notable project that enhanced the Rockies Express Pipeline's capacity.

The project was completed in December 2016. It involved a 0.8 billion cubic feet per day expansion by reversal of the pipeline's Zone 3 east-to-west capacity, via compression additions.

The project was filed for authorization with FERC by REX, Rockies Express Pipeline LLC. The operator and owner of the pipeline are Rockies Express Pipeline LLC and Tallgrass Energy Partners (75%), Phillips 66 (25%) respectively.

Here are the key details of the project:

  • Operator: Rockies Express Pipeline LLC
  • Owner: Tallgrass Energy Partners (75%), Phillips 66 (25%)
  • Capacity: 800 million cubic feet per day (MMcf/d)
  • Cost: US$532 million
  • Status: Operating
  • Start Year: 2017

Location and Capacity

The Rockies Express Pipeline spans a significant distance, stretching from the Rocky Mountains of Colorado to eastern Ohio. This lengthy pipeline is a testament to the country's vast energy infrastructure.

The pipeline's capacity is also noteworthy, with a maximum allowable operating pressure of 1,480 pounds per square inch (10,200 kPa). This ensures that the pipeline can efficiently transport large volumes of natural gas.

Here's a breakdown of the pipeline's key statistics:

  • Length: 1,679 miles (2,702 km)
  • Capacity: 3.6 billion cubic feet per day (37 billion cubic metres per annum)
  • Diameter: varies between 36 and 42 inches (910 and 1,070 mm), primarily 42 inches (1,100 mm)
  • Cost: around $5 billion

Rex — East is a 638-mile long pipeline from Audrain County, Missouri, to Clarington in Monroe County, Ohio.

It's a 42-inch pipeline that's part of the larger Rockies Express Pipeline system. The pipeline was constructed in two segments, with the 444-mile leg completed in June 2009 and the 195-mile leg completed in November 2009.

The construction of Rex — East was approved by the Federal Energy Regulatory Commission (FERC) on 30 May 2008. The cost of this phase was around $3,132 million.

This pipeline has increased the capacity of the Rockies Express Pipeline system, with the 444-mile leg adding an additional 1600 Mmcf/day and the 195-mile leg increasing the capacity to 1800 Mmcf/day.

The pipeline operates at a maximum allowable operating pressure of 1,480 pounds per square inch (10,200 kPa).

Location

The pipeline spans a significant distance, running from the Rocky Mountains of Colorado to eastern Ohio. This route takes it through diverse landscapes and climates.

The pipeline's starting point is in the Rocky Mountains of Colorado, where the terrain is rugged and mountainous.

The Rockies Express Pipeline has undergone several expansion projects to increase its capacity and reach. The first expansion project, completed in 2015, added 600 million cubic feet per day of capacity to the pipeline.

Several expansion projects have been proposed to transport gas further to the northeast. These projects include the Northeast Express project, which would run from Clarington and Lebanon, Ohio, to Princeton, New Jersey, and the TIME III Project, which would expand the Texas Eastern Transmission pipeline by 4 billion cubic meters per year.

The Rockies Express Pipeline has also expanded to the west, with the REX – West project adding a 713-mile pipeline from Weld County, Colorado, to Audrain County, Missouri. This project was commissioned in 2008 and has a capacity of 3.6 billion cubic feet per day.

The pipeline system has a diameter that varies between 36 and 42 inches, with a maximum allowable operating pressure of 1,480 pounds per square inch. The initial cost of the pipeline was around $5 billion.

Here are some key statistics about the expansion projects:

  • Expansion Project 1: 600 million cubic feet per day (MMcf/d), 14 miles, $75 million
  • Expansion Project 2: 1,200 MMcf/d, no new length, $79 million
  • REX – West: 713 miles, 42-inch diameter, $5 billion
  • Cheyenne Hub Enhancement Expansion: 1,000 MMcf/d, $185 million

Announcements and Agreements

Tallgrass has announced anchor shipper precedent agreements for a new pipeline that will transport natural gas from the Permian Basin to the Rockies Express Pipeline and other points of delivery.

The pipeline project is designed to be capable of up to 2.4 Bcf of natural gas transportation.

Firm transportation commitments under the already executed precedent agreements are sufficient to financially justify construction of the pipeline project, subject to customary regulatory and corporate conditions and approvals.

The pipeline project has a target in-service date in late 2028.

Partnership

The Rockies Express Pipeline is a notable example of a partnership in action. The pipeline is operated by Rockies Express Pipeline, LLC, a partnership between Tallgrass Energy Partners, Phillips 66 and Sempra Energy.

Kinder Morgan Energy Partners and Sempra Energy acquired Entrega Gas Pipeline Inc. from EnCana Corporation in February 2006. This significant move marked a major development in the pipeline's history.

ConocoPhillips acquired 24% of the project in June 2006, further solidifying the partnership.
