The ISO performs annual studies to identify the minimum local resource capacity required in each local area to meet established reliability criteria. As part of this study process, the ISO obtains input from stakeholders on the criteria, methodology and assumptions used as inputs into the studies, and feedback on the study results. Based on the study results, load serving entities receive a proportional allocation of the minimum required local resource capacity by transmission access charge area, and submit resource adequacy plans to show that they have procured the necessary capacity.
