Plans and proposals for the transmission system

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 classifications

Network and asset renewal projects have targeted in-service dates that are designed to address system limitations and condition needs. The network projects are classified into one of three possible categories – Planned, Proposed or Provisional – depending upon the stage of the project.
