Impact analysis of Entergy-MISO integration on power system economics

As five Entergy utilities announced their agreement to join Mid-Continent Independent Transmission System Operator (MISO) at the end of 2012, significant shift in the structure of electric operating territories was expected. Consequently, a large portion of electrical region in the South would become part of MISO single dispatch area. US regional electricity map has to be redrawn and power flow pattern is expected to change dramatically. Entergy areas could become southern region of MISO, which we call MISO-South area. This paper analyzes and reports on the impact of Entergy integration into MISO on economics of neighboring power systems.
