Zone 3 Capacity Enhancement

Two weeks ago, Tallgrass Energy, operator of the Rockies Express Pipeline (REX) received final approval to begin construction on its Zone 3 Capacity Enhancement (Z3CE) expansion project, its second east-to-west flow capacity expansion in as many years. The last one went into service last August and has been running at capacity near 1.8 Bcf/d for much of winter 2015-16. The Z3CE expansion will again increase westbound takeaway capacity on the mainline from the heart of the Marcellus/Utica shale by another 0.8 Bcf/d, on top of the existing 1.8 Bcf/d. Today we bring you the up-to-the-minute scoop on the latest REX expansion.
