Summary
This Nodal Protocol Revision Request (NPRR) expands the use of the Security-Constrained Economic Dispatch (SCED) Base Point Below High Dispatch Limit (“SBBH”) flag to signify that ERCOT has instructed an Intermittent Renewable Resource (IRR) or Direct Current (DC)-Coupled Resources not to exceed its Base Point. These changes improve the control of IRRs in order to more efficiently manage Generic Transmission Constraint (GTC) stability limits. Additionally, the Base Point Deviation Charge threshold for IRRs is adjusted to encourage better SCED Base Point control.
