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

LEAWOOD, Kan.–(BUSINESS WIRE)–Tallgrass Energy Partners, LP (NYSE: 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 (NYSE: APC) and DCP
Midstream, LP (NYSE: 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 (NYSE: 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.”
