From Negative to Positive: A Balance-Sheet NPV Profile of the Trans Mountain Pipeline under State Ownership

Abstract

Governments periodically acquire capital-intensive infrastructure projects that private actors are unable or unwilling to complete, often under conditions where conventional net present value (NPV) analysis indicates strongly negative project economics. Such interventions are typically framed as political rescues or fiscal failures, with limited attention paid to how forward-looking project value evolves once construction risk is resolved. This paper examines the Trans Mountain Expansion Project (TMX), acquired by the Government of Canada in 2018, as a detailed empirical case of infrastructure completion under state ownership. Using publicly available financial statements, the paper constructs a balance-sheet Net Present Value Profile that evaluates the project at successive points in time based solely on remaining future cash flows, treating all past expenditures as economically irrelevant for valuation. The results show that TMX’s forward-looking NPV was strongly negative at the time of acquisition but became decisively positive as construction risk was eliminated, stabilizing at a high steady-state value upon commissioning. This transition occurs without any revision to historical costs or operating assumptions and is robust to discount-rate variation. The analysis demonstrates how state intervention can function as risk absorption rather than capital misallocation, converting uncertainty into a valuable operating asset. By distinguishing completion dynamics from project failure cases, the paper clarifies why static ex ante NPV calculations can mischaracterize the economic logic of public intervention in long-lived infrastructure projects
