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:
The projects listed in the ISO's Interconnection Queue are typically studied serially, according to the order in which the Interconnection Requests are received. In certain circumstances, projects can be studied in a Cluster, in accordance with the Clustering provisions in Schedules 22, 23, and 25 of the Open Access Transmission Tariff. The study reports and other related materials for projects that are studied as part of a Cluster can be found below, and the study reports for projects that are being studied serially can be found on the Interconnection Request Studies page.
