Station 148 Unit Addition


TransCanada PipeLines Limited (TCPL) applied to the Canada Energy Regulator (CER) for an order approving the construction and operation of the Station 148 E1 Unit Addition, located in the municipality of Les Cèdres, Québec. 

The Project is a component of a larger project (Projet Rive-Nord) that requires new facility sets on the Canadian Mainline and Trans Québec & Maritimes Pipeline Inc. (TQM) systems owned by TCPL and TQM respectively, that are required to meet contracted natural gas demand to the Énergir Eastern Delivery Area and East Hereford. The anticipated in-service date for the facility is November 2021. 

The Project application was submitted to the CER concurrently with TQM’s application for the Blainville Compressor Station and East Hereford Electrical Upgrade Project, which are TQM’s components of Projet Rive-Nord. More information about the TQM project is available on the TQM site.
