It's wrong, Trans-Mountain is most certainly NOT operating at a loss. I can forgive the IEEFA authors for getting this wrong though.
Settle in for a Pipeline Regulation Thread.
Trans Mountain as a regulated asset is not running a loss. It basically can't as it is a regional monopoly, with excess demand. But it faces regulated tolls.
The distinction is probably best explained by the back and forth between Robyn Allen:
apps.cer-rec.gc.ca/REGDOCS/File/D…
A) work out the cost to run the pipe (call this "C")
B) work out the undepreciated capital costs of the pipe (Call this "K")
and
Then, this adds up to the "revenue requirement": RR
RR= C + rK
Tolls are then set to recover this amount from the shippers. i.e.-
Toll = RR / Quantity Shipped
As stated in the above excerpt from the CER decision letter:
The regulation enforced by the CER requires "K" include only the undepreciated capital associated with the EXISTING pipe.
