Alternative operations study (AOS)

The Upper Great Plains Region and the other IS owners have studied several forms of potential regional transmission organization participation since the 1990s. Beginning in 2001, the IS participants began to evaluate potential options of joining SPP, joining the Midcontinent Independent System Operator, or continuing operations on a stand-alone basis. These studies identified the option to join SPP as having the most benefit and the least risk.
