Current Status

The second regional planning cycle for this region is complete. The Regional Infrastructure Plan (RIP) for the region was published in December 2020. It is expected that the next planning cycle for this region be initiated in the next three to five years.

The Needs Assessment (NA) determined that the needs identified in the Outer Ottawa Sub-region can be addressed directly by Hydro One and Local Distribution Companies (LDCs) and further regional coordination is not required. 
As recommended by the NA, the Local Plan for B5D/D5A Load Restoration was completed. A Local Plan was also completed to address the Supply to East Ottawa Area, as identified in the IRRP phase.
