Northern Area Reliability Assessment

ATC initiated a Northern Area Reliability Assessment effort in 2014 to engage stakeholders and identify potential reinforcements due to generation uncertainties in the northern portion of the ATC system. The 10-year project list includes the following preliminary projects:

  • Plains-National 138 kV line
  • Plains-Arnold 138 kV line uprate
  • Increased Plains 345-138 kV transformer capacity
  • Morgan-Thunder-Crivitz 138 kV project

ATC had collaborated with MISO to include Plains-National in MTEP15 Appendix A and the other projects in Appendix B. ATC is supportive of Michigan’s generation addition efforts in this area and will continue to assess the need for these projects as generation proposals mature.
