  2. TEMP48_20358 • Monitored Element- LONGWOO – OAK_PHEC 138 kV LN • Contingent Element- SWSHREV XFR MIDI S 345/138 KV • Reason for Violating: Ongoing outage of xfmr; high load in area and a resource was offline, relieving resource was maxed out; it took some time to get into a good ramp range for unit to provide relief.

  4. TEMP05_20411 • Monitored Element- Bell – KSCO3 69kV LN:230 • Contingent Element- SUMNER – OXFO 138kV LN: OXFO_SUMNER • Reason for Violating: Local issue; Local generation came offline and relieving generation was not fixing the issue; Local generation brought back on line.

  5. TEMP05_20411 • Monitored Element- Bell – KSCO3 69kV LN:230 • Contingent Element- SUMNER – OXFO 138kV LN: OXFO_SUMNER • Reason for Violating: One-day outage of 138kV line; generation able to control the constraint, but a low ramp rate and the unit not staying right on dispatch led to a lot of violations.

  7. SHAHAYKNOXFR • Monitored Element- South Hayes • Contingent Element- Knoll1 XFR • Reason for Violating: High load in NW Kansas/Hays area, violated until a local resource came online after noon and another came online around 16:00

  8. SHAHAYKNOXFR • Monitored Element- South Hayes • Contingent Element- Knoll1 XFR • Reason for Violating: High load in NW area; Unit shut down, effective limit was lower than SOL and we violated until load in the area dropped off.

  10. TEMP50_20450 • Monitored Element- Ogalala – Brule 115kV • Contingent Element- Stegall 345/230 kV Xfmr • Reason for Violating: Planned outage of a Line; normal reconfigurations were not an option. TLR needed to control external impacts on the flowgate; low GSFs on SPP market resources contributed to needing to violate the flowgate up to 102% of the effective limit just to start dispatching down the primary Decrement unit. During the violations on 7/30, we ran out of dispatchable room and had to create a post-contingent load shed plan.

  12. TEMP63_20466 • Monitored Element- Mustang – Denver 115kV C.1 • Contingent Element- Mustang – Denver 115kV C.2 • Reason for Violating: A CA requested more of a resource to be brought online after a unit tripped. The plant was operating with a high Eco Min due to testing for HE 15, and the others were dispatched to their Eco Min and we had no more room to move down on the resources.

  14. OSGCANBUSDEA • Monitored Element-OSAGE CANYON 115 kV • Contingent Element-BUSHLAND DEAFSMITH 230 kV • Reason for violating: We shut down two resources, and wind in north SPS increased as well; it took some time for RTBM to resolve the loading.

  15. OSGCANBUSDEA • Monitored Element-OSAGE CANYON 115 kV • Contingent Element-BUSHLAND DEAFSMITH 230 kV • Reason for violating: Ran out of room to move down on nearby Dec units; had room to move up on Inc units but prices at the time required a violation to 101% to get those units to move up

  16. OSGCANBUSDEA • Monitored Element-OSAGE CANYON 115 kV • Contingent Element-BUSHLAND DEAFSMITH 230 kV • Reason for Violating: Resource came offline very fast; took some time for RTBM to solve and more generation at another was brought on shortly after

  18. TEMP67_20472 • Monitored Element- Renfrow7 – RenfrowWF 138kV • Contingent Element- Hunters – Woodring 345kV • Reason for Violating: Ran out of room to move up on generation; low shift factors and other flowgates binding were competing for Incs/Decs coming across peak load. Nearby wind had very low offers, so prices did not get low enough to dispatch them down.

  19. TEMP67_20472 • Monitored Element- Renfrow7 – RenfrowWF 138kV • Contingent Element- Hunters – Woodring 345kV • Reason for Violating:Online generation maxed out; high wind at windfarm, forced outage on a line made Dec GSFs a little bit lower, making it more difficult for RTBM to solve the constraint; also, this flowgate was fighting with another flowgate as well.

  21. TEMP09_20424 • Monitored Element- GORD 345/138 XFR: WICH_12 • Contingent Element- GORD 345/138 XFR: WICH_11 • Reason for Violating: Initially not much generation online in Wichita with high load, but generation came online to relieve that constraint, but it hurt Temp43 (which was also loading up due to increasing load and wind dropping in west Kansas). Temp43 violated until generation came online to support the load in the area

  22. TEMP09_20424 • Monitored Element- GORD 345/138 XFR: WICH_12 • Contingent Element- GORD 345/138 XFR: WICH_11 • Reason for Violating: Outage on 138kV line; all online local generation maxed out; generation brought online to resolve loading

  23. TEMP09_20424 • Monitored Element- GORD 345/138 XFR: WICH_12 • Contingent Element- GORD 345/138 XFR: WICH_11 • Reason for Violating: Ongoing outage of line and the return of another; high load in area; resource committed to relieve the loading

  25. TEMP43_20311 • Monitored Element- RENO 345/1kV XF: 2P • Contingent Element- SUMM 345/15kV • Reason for Violating: Initially not much generation online in Wichita with high load, but generation came online to relieve that constraint, but it hurt Temp43 (which was also loading up due to increasing load and wind dropping in west Kansas). Temp43 violated until generation came online to support the load in the area

  27. TEMP22_2092 • Monitored Element- CRSW – KSCO4 69kV • Contingent Element- HAYS – PECK 69kV • Reason for Violating: Load pocket issue; generation is the only generation that can help this constraint, and they were not following the dispatch up, so the market couldn't drive them up high enough to relieve the loading.

  29. NORXFRNORXFR • Monitored Element- NOWST1 • Contingent Element- NOWST1 • Reason for Violating: Increasing load all the nearby Inc generation was already maxed out, no relief left available across afternoon peak

  30. NORXFRNORXFR • Monitored Element- NOWST1 • Contingent Element- NOWST1 • Reason for Violating: High/increasing load. Online generation in the city was already maxed out, nothing left to move up/down to relieve the flowgate

  31. NORXFRNORXFR • Monitored Element- NOWST1 • Contingent Element- NOWST1 • Reason for Violating: Approved derate of generation and resources already at max; other generation brought online, but still not enough generation with short enough lead times; directed wind farm to 0 to try to get relief, then came up with post-contingent load shed plan

  33. TEMP119_20525 • Monitored Element- Tarby1 161/69kV • Contingent Element- AES5 – BONTP 161kV • Reason for Violating: Outage of 161kV line; this is an outlet for issue for generation. We initially violated the flowgate because unit was OOMEd (in preparation for the outage) and not dispatchable. Once we released the OOME, they did not follow dispatch or their ramp rate, so they were OOMEdagain.

  34. TEMP119_20525 • Monitored Element- Tarby1 161/69kV • Contingent Element- AES5 – BONTP 161kV • Reason for Violating: Outage of line; this is an outlet for issue for generation. Unit did not follow dispatch or their ramp rate, they had to be called to tell them to go down to resolve the loading.

  36. TEMP125_20532 • Monitored Element- Rose – El Paso 138kV • Contingent Element- Rose – Weaver 138kV • Reason for Violating: Ongoing outage of a line; no generation online in area. Units were committed to relieve the loading, but it took a while for load to drop and the constraint to be relieved.

  38. TEMP127_20536 • Monitored Element- Seward – St. John 115kV • Contingent Element- Finney – Hitch 345 kV • Reason for Violating: Sharp increase in the area wind; wind farms limited themselves, which resolved most of the loading.
