| NPRR381 | Registration Requirements for Interconnecting Entities | This Nodal Protocol Revision Request (NPRR) creates a new type of Market Participant called an “Interconnecting Entity” (IE). The NPRR requires Entities who wish to interconnect a new Resource or make certain changes to a Resource to register with ERCOT and to comply with ERCOT standards and procedures during the interconnection or change process. Entities that are not presently registered as Resource Entities will now be required to register as IEs before they may seek registration as Resource Entities. Existing Resource Entities who seek interconnection of a new Resource or certain changes to an existing Resource must amend their registration to add the IE designation, and may amend the registration to withdraw the IE designation when the new Resource is energized or the proposed changes are implemented. This NPRR does not require current Resource Entities to seek retroactive registration as an IE for Resources already energized. However, this NPRR would require Entities currently involved in the interconnection process to register as IEs. | 06/08/2011 | ERCOT | No | 1.6.5, 2.1. 2.2, 3.3.1, 16.5, Registration as a Resource Entity 16.16, (new) 16.16.1, new) 16.16.2, Registration Process for an Interconnecting Entity (new) 16.16.2.1,(new) 16.16.2.2, 16.16.2.3, (new) 16.16.3, (new) 22, Attachment A, 22, Attachment C, | Withdrawn | ||
| NPRR409 | Outage Planning Criteria Clarifications and Enhancements to Narrow Gap Between Real-Time Operations and Outage Planning | This NPRR adds a new definition of Outage Planning Contingencies to be consistent with NOGRR078 and PGRR011. This NPRR also revises factors used by ERCOT to evaluate requests for Generation and Transmission Outages received from Market Participants to allow for 90th percentile variation of weather driven Load, generation availability, and transmission line ratings of dynamically rated lines. This NPRR ensures that Outage planning studies do not double count generation capacity as being available simultaneously for both congestion management and Ancillary Services including Responsive Reserve (RRS), Regulation Up (Reg-Up), and Non-Spinning Reserve (Non-Spin), unless ERCOT Operations has processes in place to allow for location specific deployment of the Ancillary Service reserves for congestion management purposes. Finally, this NPRR ensures that, if in Real-Time operations ERCOT determines that a generic constraint definition and associated transfer limit(s) is required for secure operation of the ERCOT System, then this same generic constraint shall be similarly modeled in Outage planning studies. | 09/07/2011 | Luminant Energy | No | 2.1, 2.2, 3.1.5.11 | Withdrawn | ||
