Guide to Referencing MISO

Effective April 26, 2013, MISO amended its Certificate of Incorporation on file with the State of Delaware to reflect a change in its legal name to “Midcontinent Independent System Operator, Inc.”  No other changes to the MISO business resulted from this change.

Because of the recent growth of MISO operations, “Midcontinent” better represents our expanding footprint.
