The marked numbers differ from the Flexible Capacity Need table (Figure 7) by 1 megawatt in the Flexible Capacity Assessment filed May 1, 2014. For allocation among LSEs we will use numbers in the above table. In addition, the CAISO proposes to divide the flexible capacity needs into three categories. These categories are defined based on the CAISO’s assessment of the different types of flexible capacity needed to address the CAISO’s needs. Specifically, in the flexible resource adequacy criteria and must offer obligation (FRAC-MOO) stakeholder initiative, the CAISO proposed the following flexible capacity categories: Category 1 (Base Flexibility): Operational needs determined by the magnitude of the largest 3-hour secondary ramp. Category 2 (Peak Flexibility): Operational needs determined by the difference between 95% of the maximum 3-hour net-load ramp and the largest 3-hour secondary net-load ramp.
