| Description: | This Nodal Protocol Revision Request (NPRR) adds language to specify the need for ERCOT to post to the Market Information System (MIS) Certified Area the current time since a Generation Resource last went Off-Line (in hours) and the corresponding startup time ERCOT is using for of all Off-Line Generation Resources which may be considered in any Reliability Unit Commitment (RUC) process. |
| Reason: | The posting of this information increases reliability by allowing Qualified Scheduling Entities (QSEs) with Resources the ability to verify the temporal constraints ERCOT is using in the RUC process so that commitment decisions will be made with accurate availability information. If ERCOT’s Security Sequence is utilizing changes to the telemetered Resource Status to detect the temporal condition of a Resource, there may be inadvertent changes to the Resource Status in the QSE’s control system that do not reflect the actual condition of the Generation Resource. Posting of the Resource’s current Off-Line hours and corresponding startup times will allow QSEs to verify the assumed condition used by RUC in the Security Sequence. |
