The Midcontinent Independent System Operator's (MISO's) geographic footprint extends down the middle of the U.S. Because of the structure of its market, MISO has artfully avoided some nasty policy and economic issues that characterize its neighbors in the Mid-Atlantic and Northeast. However, MISO still faces many of the same market forces that are transforming the electric generation and distribution business across the country. The scope of the Midcontinent Independent System Operator (MISO) is vast. One of the original regional transmission and wholesale market operators growing out of the Federal Energy Regulatory Commission's (FERC's) restructuring of much of the U.S. electricity business in the late 1980s and early 1990s, MISO stretches from Manitoba in central Canada to the Gulf of Mexico in Southern Louisiana (Figure 1).
