This report delves into the historical framework and current analysis regarding the Nebraska Public Power District's (NPPD) involvement with the Mid-Continent Area Power Pool (MAPP) and its transition towards the Southwest Power Pool (SPP). It discusses the operational and economic benefits of joining the SPP over MISO, the drivers behind these decisions, and outlines the outcomes of various modeling analyses. The recommendation advises full membership in SPP, aiming to enhance efficiency and reliability for the Nebraska utilities, while navigating the complexities of new policies and processes that accompany this membership transition.
