Transmission reliability margin
Currently, the ISO implements certain adjustments to intertie schedules within operating hours. Using a mechanism known as Transmission Reliability Margin, the ISO will be able to anticipate these transmission constraints in advance by reflecting them in market processes before schedules are awarded in the hour-ahead scheduling process. In this initiative, the ISO will develop tariff revisions and the NERC-required transmission reliability margin implementation document. The document will provide greater clarity regarding ISO management of transmission constraints in the real-time market.
