Summary of key findings 

• All longer term area needs were described and addressed in the Zone 2 – 2012 study results and Zone 2 – 2016 study results sections.

There was one thermal limitation and three area bus voltage limitations that appeared in Table ZS-3. All of these limitations are addressed by generation adjustments and/or the projects outlined in Zone 2 – 2012 study results and Zone 2 – 2016 study results. In addition, further explanation can be found in the ATC Energy Collaborative – Michigan section.

No performance limits were exceeded for Category A conditions for all 2021 analysis.

The lead times necessary to implement the corrective plans that are scheduled for 2017 through 2021 were considered and taken into account prior to assigning an in-service date for each associated project. All of the projects scheduled for the longer term planning horizon have an “In-service date” that matches the “Need date”, except the following projects:

Projects whose “Need date” precedes the “In-service date”

• None

Projects whose “In-service date” precedes the “Need date”
