State of North Carolina, ex rel. Roy Cooper, Attorney General, v. Tennessee Valley Authority

Analysis Group was retained by the Attorney General of the State of North Carolina in a public nuisance lawsuit brought against the Tennessee Valley Authority (TVA) to assess whether additional pollution control devices requested by the State of North Carolina were economically reasonable and financially feasible for TVA to implement. An Analysis Group team including Managing Principals Andrea Okie and Pavel Darling and Principal Paul Hibbard supported Senior Advisor Susan F. Tierney over the course of this multi-year engagement. Dr. Tierney provided expert testimony including multiple reports and trial testimony, in which she examined the relevant market landscape, assessed TVA's financing capability and debt obligations over time, and analyzed the impact of the proposed pollution controls on electricity rates paid by TVA's customers.
