Tallgrass Energy Announces Open Season to Link Natural Gas from the Denver-Julesburg Basin to Markets Across the Country

Tallgrass Energy Partners, LP TEP is pleased to announce the launch of an open season to transport natural gas on the Cheyenne Connector pipeline ("Cheyenne Connector") from the Denver-Julesburg Basin ("DJ Basin") to the Rockies Express Pipeline ("REX") Cheyenne Hub just south of the Colorado-Wyoming border. Cheyenne Connector has signed long-term precedent agreements to transport 600 MMcf/d of natural gas with affiliates of Anadarko Petroleum Corporation APC and DCP Midstream, LP DCP. Cheyenne Connector will provide takeaway solutions for DJ Basin gas producers, connecting natural gas to REX's Cheyenne Hub where it can then be delivered to numerous demand markets across the country on either REX or other interconnected pipelines.

Cheyenne Connector, to be operated by Tallgrass, will be a large-diameter pipeline approximately 70 miles long, with an initial capacity of at least 600 MMcf/d and significant capability for expansion. Tallgrass is jointly developing the pipeline with Western Gas Partners, LP WES and DCP, who both hold an option to invest in Cheyenne Connector at a later date. Cheyenne Connector is expected to be in service in Q3 2019, subject to certain conditions, including required approvals from the Federal Energy Regulatory Commission.

"We are pleased to support this takeaway solution which will facilitate continued growth of the DJ," said Scott Moore, Senior Vice President for Anadarko.

"We believe this project is another important step in developing and expanding market access to serve our customers and meet their DJ production growth," said Don Baldridge, President of Commercial for DCP.

TEP's Chief Commercial Officer Matt Sheehy agreed, saying, "Tallgrass is excited to work with Anadarko and DCP to serve the needs of the producing community in the DJ Basin. As production increases in the basin, additional pipeline capacity is needed, and by taking gas to the REX Cheyenne Hub, Cheyenne Connector will further link Rockies gas to diverse end-user markets across the country."
