Audit

The TVA developed an integrated resource plan (IRP) to guide the organization in meeting future energy demand. Due to the importance of the TVA's IRP as a directional document for TVA's future, the OIG evaluated the adequacy of TVA's development process for the 2015 IRP, including demand-side and supply-side strategies. We determined TVA's process for developing the 2015 IRP was adequate in considering potential future uncertainties and associated responses. Specifically, we determined the IRP project team met stakeholder input objectives by engaging numerous stakeholders and incorporating public opinions into the development of the IRP; considered project risks, including those related to project management; and incorporated practices commonly seen in integrated planning processes, as well as best practices, into the IRP. In our opinion, the IRP team improved on integrated resource planning efforts as the 2015 IRP incorporated lessons learned from the 2011 IRP, where applicable. Additionally, we determined scenario and strategy development and consideration of IRP inputs were consistent with those of other organizations. TVA developed metrics to analyze the portfolios generated in the 2015 IRP that reflected stakeholder input, where applicable, and were consistent with TVA's strategic mission and imperatives. Lastly, we determine considerations included in the Supplemental Environmental Impact Statement were adequate.
