| Sections: | 1.4 |
| Description: | This Nodal Operating Guide Revision Request (NOGRR) deletes the definition of Credible Single Contingency from the Operating Guides. |
| Reason: | The original intent of this NOGRR was to respond to the 2/14/13 ROS directive to the Operations Working Group (OWG) and based on the recommendation of the Operations and Planning Synchronization Task Force (OPSTF) regarding Issue 6 of the OPSTF Issues List Matrix, which relates to the "[u]se of double circuit contingencies to develop operating limits." The OPSTF recommendation is as follows: "OPSTF discussed a proposal that a DCKT outage be considered only if it caused a reliability problem. The 'push-back' was that it is hard for the market to model contingencies that are sometimes run and sometimes not. ERCOT commented that this would be complex, burdensome and require new tools for System Operations. OPSTF recommends that ROS direct OWG to modify the Operating Guides language (pg. 1-15) to better reflect the actual practice." After further review, the OWG has agreed to delete the definition of Credit Single Contingency from the Nodal Operating Guides. The definition will be incorporated in the Protocols as the use of the term is being introduced in Nodal Protocol Revision Request (NPRR) 540, Clarification of Credible Single Contingency. |
