There were no DRUC commitments in November. There were 3 HRUC commitments in November.

There were thirty-one instances of activity on the Generic Transmission Constraints (GTCs) in November. Notable Constraints for November 26 reportable events (49 for October 2016) 167 congestion events (347 for October 2016, 228 for November 2015) Nodal protocol section 3.20 specifies that ERCOT shall identify transmission constraints that are active or binding three or more times within a calendar month. As part of this process, ERCOT reports congestion that meets this criterion to ROS. In addition ERCOT also highlights notable constraints that have an estimated congestion rent exceeding $1,000,000 for a calendar month. These constraints are detailed in the table below. Rows highlighted in blue indicate the congestion was affected by one or more outages. For a list of all constraints activated in SCED for the month of November, please see Appendix A at the end of this report. # of Days Overloaded Congestion Transmission Contingency Name Comments Element Rent Project Active Panhandle Multiple area line Basecase Panhandle GTC 20 $17,822,792.99 Upgrade outages Planned Outage on 345 DCKT Hill Country - Marion and Cibolo - Schertz Cibolo to Schertz kV line from SKYLINE 11 $7,220,084.57 Elmcreek 345 kV 138kV T-Line (T303) to MARION and ELMCREEK DCKT Gibbons Creek - Jewett - Singleton Houston Import Unavoidable extension 1 $6,665,002.04 Singleton 345 kV 345kV Project on 345 kV bus
