To meet the growing demand for natural gas, we are constructing the 2021/2022 Storage Enhancement Project. The Project -- located in St. Clair Township, in the County of Lambton -- will allow us to store additional natural gas and to improve the deliverability of our storage operations. The Project involves:

  • Increasing the maximum operating pressure (“MOP”) of three existing storage pools (Ladysmith, Corunna and Seckerton);
  • Re-entering the stratigraphic test well in the Ladysmith Storage Pool and converting it to a horizontal natural gas storage well and connecting the well to the gathering system;
  • Upgrading the existing gathering system at the Ladysmith Storage Pool from Nominal Pipe Size (NPS) 16 to NPS 20;
  • Constructing approximately 2.2 kilometres (km) of NPS 24 natural gas pipeline to connect the Payne Storage Pool to the Corunna Compressor Station located on Tecumseh Road, in St. Clair Township, Ontario;
  • Re-routing the existing Ladysmith Storage Pool pipeline to connect with the Payne Storage Pool Pipeline at the existing Payne/Kimball Station; and
  • Upgrading and installing new equipment at existing stations.

The Project was approved by the Ontario Energy Board in 2021, and the vast majority of construction will occur in 2022.

The Project Study Area (PSA) was developed to identify the Preferred Pipeline Route and other infrastructure works associated with the Project, as well as to develop the "limits of analysis" of background environmental and socio-economic baseline conditions to be assessed as part of the Environmental Report (ER). The PSA is generally bounded approximately by Ladysmith Road to the west, Petrolia Line to the north, Tecumseh Road to the east and Courtright Line to the south.
