Westcoast Energy Inc., doing business as Spectra Energy Transmission, is seeking National Energy Board (NEB) approval to construct and operate a loop of the Fort St. John Mainline in northeast British Columbia.

The proposed Wyndwood 36-inch expansion project is in the Peace River district southwest of Chetwynd near Stone Creek and extends roughly 28 kilometres west to Westcoast’s existing Compressor Station No.2 (CS 2) at Willow Flats. In addition to a loop of the existing 30-inch mainline along with pig sending and receiving facilities, the project will include minor modifications to piping at CS2.

The Wyndwood expansion will enable Westcoast to provide incremental firm transportation service from receipt points along the Fort St. John Mainline.

In a regulatory filing, Westcoast said it has received requests for additional Zone 3 firm transportation service in order to accommodate increasing levels of production from the Montney formation in northeast B.C. In response to a binding open season conducted in the summer of 2015, Westcoast received bids from, and subsequently entered into expansion service agreements with, shippers for 50 mmcf per day of incremental firm service. The weighted average term of the expansion service agreements is approximately 12 years.

Westcoast said it hopes to receive NEB approval in March 2017 and start CS2 work in May. Pipeline construction would begin in August 2017 with a planned in-service date for the proposed expansion facilities in the first quarter of 2018.

Westcoast’s Toll and Tariff Task Force has unanimously supported Westcoast’s proposal for the cost of the project to be included in the Zone 3 cost of service and tolled on a rolled-in basis.
