Tallgrass to Develop New Cushing to St. James Crude Oil Pipeline and Gulf Coast Liquids Export and Import Terminal


Producers get Greater Optionality and Wellhead to End-Market
Batching Capability

Tallgrass Energy, LP (NYSE:TGE) ("Tallgrass") today announced plans to
develop a new crude oil pipeline from Cushing, Okla., to the St. James,
La., refining complex, as well as a separate new export-capable liquids
terminal strategically located near the mouth of the Mississippi River.

The proposed Seahorse Pipeline ("Seahorse") is expected to be 30 inches
in diameter and approximately 700 miles long, with the capacity to
transport up to 800,000 barrels of crude oil per day from Cushing to the
Louisiana Gulf Coast. The pipeline will operate as a common grade batch
system that, along with Tallgrass' Pony Express Pipeline, will ensure
domestic refiners and international markets have access to "clean"
barrels from five different production basins.

The proposed new terminal, Plaquemines Liquids Terminal ("PLT"), is a
joint development project with Drexel Hamilton Infrastructure Partners,
LP and is being structured as a Public-Private Partnership (P3) in
concert with the Plaquemines Port & Harbor Terminal District (PPHTD), a
Louisiana state agency. The terminal is expected to be fully operational
in 2Q 2020 and is permitted for up to 20 million barrels of storage. PLT
will have the ability to fully load and unload Post-Panamax vessels
(each with a capacity of about 1 million barrels) and barges on its
multiple deep-water docks. Tallgrass anticipates building a separate
offshore pipeline extension that would give PLT the added capability of
loading Very Large Crude Carriers ("VLCC") by 3Q 2021.

"The Seahorse Pipeline and Plaquemines Liquids Terminal projects build
on our strategy to provide diversity of supply and greater market
optionality to our customers," said Tallgrass Energy President and CEO
David G. Dehaemers Jr. "These projects provide highly desired take-away
capacity from Cushing to the St. James refining complex, providing
interconnectivity to more than 2.5 million barrels per day of refining
capacity and access to international markets."

"Our customers can rest comfortably knowing that their barrels will be
transported on Seahorse in common grade batches from Pony Express
direct-connected supply basins and Cushing sourced supplies, which will
protect the integrity and help preserve the value of their product all
the way to Seahorse's St. James and export terminal destinations," said
Tallgrass Chief Operating Officer Bill Moler. "From there, our customers
will be able to access international refining markets."

Tallgrass expects to launch its initial open season for the Seahorse
Pipeline on Aug. 15, 2018. The open season is expected to run for 45
days. Prospective shippers may review details of the open season after
executing a confidentiality agreement obtained by contacting Tallgrass
representatives Kyle Quackenbush, 303.763.3319; Andrew DiPaolo,
303.763.3329; or Dean Dick, 307.232.4430.

Project investment is dependent upon obtaining satisfactory customer
interest and receiving applicable state and federal permits, among other
