Description: This Nodal Protocol Revision Request (NPRR) revises the calculation of Physical Responsive Capability (PRC) to more accurately indicate the amount of capacity that is available to respond to a frequency disturbance, as discussed during the Energy Emergency Alert (EEA) Workshop. Accurate monitoring of the level of frequency-responsive reserves is important during all conditions and especially during Emergency Conditions where capacity providing Responsive Reserve Service is released to Security-Constrained Economic Dispatch (SCED), so that operators know how much remaining capacity is available on the system to respond to disturbances and can take appropriate actions.
