Background
The Many Islands pipelines began operating between 1966 and 2021, each with their own capacities. The system connects to the Nova Gas Transmission (NGTL) Pipeline, TransGas Pipeline, Williston Basin Gas Pipeline, Foothills System Gas Pipeline, and NorthWestern Energy pipeline system.[1]
The Steelman-North Portal segment is located on the Saskatchewan-North Dakota border and historically exported SK gas to the US. Many Islands Pipe Lines (Canada) filed an application in 2019 to make this segment bi-directional due to declining gas production in SK.[1]
The Loomis-Herbert segment is 131km and located on the Saskatchewan-Montana border. It entered service in 1972, importing gas from Montana. Gas has not been imported on this segment since 2015. In 2017, Many Islands Pipe Lines (Canada) filed an application to make the segment bi-directional.[3]
The Shaunavon Interconnect segment is 2km and connects the Many Islands system to the Foothills System Gas Pipeline via the Loomis-Herbert segment. It was complete in 2020.[1]
The Norquay-Benito segment is 37.3km of 6 inch diameter steel pipeline located on the Saskatchewan-Manitoba border. It came into service in 2000, with some segment replacement occurring in 2020.[4][5]
The Macklin-Unity segment is located on the Saskatechewan-Alberta border and connects with the Nova Gas Transmission (NGTL) Pipeline.[1]
The Husky-Marwayne segment is 15km and is located on the Saskatchewan-Alberta border.[1]
The Husky Bi-Provincial Upgrader segment is 7.5km of 12.75 inch diameter pipeline on the Saskatchewan-Alberta border. It came into service in 1992.[6]
The Cold Lake-Beacon Hill Segment is 31km of 20 inch diameter pipeline on the Saskatchewan-Alberta border. It was completed in 2021.[1]
The Esther-Smiley segment is a 31.5km, 8.6 inch diameter pipeline located on the Saskatchewan-Alberta border that was partially abandoned in 2022. The remaining portion was sold to TransGas.[1][7]
