Plans and proposals for the transmission system

For planning purposes, ATC divides 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.

	Planned	Proposed	Provisional
Status of ATC planning activities	Studies complete	Studies not complete	Studies not complete
Application for regulatory approval	Application pending or issued	None	None
Project status	Project in construction planning phase or under construction	Project identified as preferred alternative	Project is not necessarily the preferred project alternative
Asset-renewal projects generally fall into the Provisional or Planned categories.
