Tallgrass Tight-Lipped on Proposed Natural Gas Pipeline Moving Supply From Permian to REX

Natural Gas Intelligence · last updated

Tallgrass Energy Partners LP is preparing to launch a binding open season on Monday (July 21) to solicit firm commitments for a pipeline project that would move up to 2.4 Bcf/d of natural gas from the Permian Basin to the Rockies Express Pipeline LLC (REX), though the company has kept details of the proposed route under wraps.

Dashed lines indicate speculative paths under evaluation.

Tallgrass announced in May it had secured anchor shipper precedent agreements sufficient to justify construction. The open season would seek to fill up the remaining available capacity on the pipeline. Tallgrass did not provide a closing date. The system could begin service, depending on commitments, in late 2028.

“The new pipeline project is unique in that it will enable affordable and plentiful natural gas to access markets broadly across the U.S., including multiple major markets that are key hubs of activity for industrial, agricultural and data center development,” Tallgrass stated.
