This Nodal Protocol Revision Request (NPRR) clarifies the difference between Ancillary Service capacity deployment and energy deployment and how it affects Security-Constrained Economic Dispatch (SCED). This NPRR also proposes non-substantive administrative changes, such as correcting acronym and defined term usage and section references.
This NPRR is needed to provide more clarity and make the Nodal Protocols consistent with Energy Management System (EMS)/Market Management System (MMS) whitepaper and current MMS implementation.
