For a co-owner of a nuclear power plant project in the Southeastern US, evaluated the prudency of past decisions to start and continue construction until the project was eventually terminated. These investment decisions by the co-owners of the project were subject to multiple class-action lawsuits regarding the appropriateness of recovering the past investment costs from the utility’s customers. Assessed the ranges of long-term outlooks on major market fundamentals and project costs as of the past decision points in order to assess the projected economics of continuing the project against options involving termination and replacement by other new resources.
