Why does Edison Sault use MISO?
The transmission assets formerly owned by Edison Sault are now owned by ATC (American Transmission Company). MISO manages the flow of electricity over many transmission lines, including those owned by ATC. MISO was specifically configured to comply with FERCs (Federal Energy Regulatory Commission) concept of an independent organization that will ensure the smooth regional flow of electricity in a competitive wholesale marketplace. The commission concluded that these RTOs could address the operational and reliability issues confronting the industry and eliminate undue discrimination in transmission services that can occur when the operation of the transmission system remains in the control of a vertically integrated utility.
