The studies are performed to ensure that system reliability criteria and standards for no adverse impact are met. They typically consist of thermal, voltage, stability, and short-circuit analyses, and include studies related to:
Projects listed in the ISO’s Interconnection Queue are studied as a Cluster of projects associated with Interconnection Requests submitted during the related Cluster Request Window. In certain circumstances, projects can be supported by a Cluster Enabling Transmission Upgrade (“CETU”) identified by a Cluster Enabling Transmission Upgrade Regional Planning Study (“CRPS”) in accordance with the CETU provisions in Schedules 22, 23, and 25 of the Open Access Transmission Tariff. The study reports and other materials related to CETUs can be found below, and the study reports for interconnection request studies can be found on the Interconnection Request Studies page.
