Summary
This Nodal Protocol Revision Request (NPRR) introduces Fast Frequency Response (FFR) as a subset of Responsive Reserve (RRS). FFR is designed to support frequency at 59.8 Hz instead of 59.7 Hz leaving existing Load Resources other than Controllable Load Resources providing RRS intact at 59.70 Hz so that they will have higher probability of being available for the next worst event. Once deployed, FFR can reset in 15 minutes and be ready for the next event.
