Recent Successes

MountainWest Pipeline (MWP) held an open season from October 16, 2023 to November 16, 2023, to solicit bids for its proposed Uinta Basin Expansion (UBE) project. The UBE project would provide incremental firm transportation up to 113,300 Dth/d capacity from MWP’s Brundage Mountain meter station to the Chipeta Processing delivery point. MWP received anchor shipper bids from four shippers as part of the open season. As a result of the open season, and shipper elections in their open season bids, three of the four anchor shipper bidders were awarded a pro rata share of the entire amount of UBE project capacity. MWP has executed precedent agreements with the three winning bidders and filed a Prior Notice request with the FERC on January 16, 2024. MWP is targeting a July 1, 2024 in-service date for the UBE project facilities.
