Current Status

The first regional planning cycle for this region is complete. The Regional Infrastructure Plan (RIP) for the region was published in December 2015. It is expected that the next planning cycle for this region be initiated in the next three to five years.

This region was the subject of an Integrated Regional Resource Plan (IRRP). Two projects have been identified in the IRRP to address the near and medium-term needs in this region: (1) the Guelph Area Transmission Reinforcement (GATR) project, and (2) the M20D/M21D in-line switches project. The GATR Section 92 application filed by Hydro One was recently approved by the OEB. Further information and relevant documents about these projects are provided below.
