Plans and proposals

For planning purposes, we divide our service area into five zones representing distinct geographic or usage areas. Within each zone, we compile and assess the transmission system needs.

Project classificationszonemap

Within each zone, we have recommended network and asset renewal projects to address system limitations. The network projects are classified into one of three possible categories – Planned, Proposed or Provisional – depending upon the stage a project may be in. These categories are consistent with those used by MISO.
