The ISO performs an annual study to identify the flexible capacity needed on the ISO system, which guides flexible resource adequacy procurement for each year. The study process includes gathering stakeholder input on the criteria, methodology and assumptions used to build the assessment. Then, based on the study results, load serving entities receive an allocation of the total flexible capacity required.
