Expected In Service Date: 6/1/2020 Estimated Cost: $5,900,000 System Needs: For an outage of Sioux-Belleau kv Line with Callaway generation offline, the existing conductor would be loaded to about 104% of its rating in 2021 summer case, with 1- in-10 load levels. Target Appendix: B in MTEP13 Preliminary Project Type: Other Reliability

16 Projects Moving to Appendix B Less than $5M Target Appendix PrjID Project Name Project Description B in MTEP Meramec Watson kv Line Reconductoring Reconductor 3.7 miles of 795 kcmil AA conductor between Watson Substation and the Mackenzie Switch Rack with conductor capable of carrying 1200 A under summer emergency conditions. Expected ISD Estimated Cost System Need 1 Jun 18 $2,107,484 C3: Existing conductor would be loaded to 123.6% of its 233 MVA rating for the coincident outage of the Central Watson 1 and Baumgartner Watson kv Lines, based on 2011 analysis. Possible loss of Watson Substation load should this line trip. B in MTEP Maurer Lake 161 kv Capacitor Bank Install 30 Mvar, 161 kv capacitor bank and PCB. B in MTEP Pike Substation Transformer Reconnectiion Reconnect Pike kv Transformer #1 to 161 kv Bus #1. B in MTEP Rush Joachim kv Position Upgrade Rush Island 345 kv Switchyard Upgrade the Rush Island terminal of the Rush Island Joachim kv line to a minimum of 2500 A capability by replacing the 2000 A wavetrap and reconnecting the 2000:5A CTs to 2500:5A. 1 Jun 15 $1,250,000 Need voltage support to Maurer Lake for the outage of the Missouri City Maurer Lake 161 kv Line. Maurer Lake 161 kv voltage would be about 87% in 2016 summer following the line outage, based on 2011 analysis. 1 Jun 14 $100,000 Voltage support to Pike area in response to outage of Pike Bus Tie Breaker #16082 or Pike Peno Creek outage. Pike 161 kv voltage would be 94% in 2016 summer following these outages or an outage to Pike Dundee 3 with Peno Creek generation offline, based on 2011 analysis. 1 Jun 17 $100,000 Maintain import capability into Ameren Missouri.
