Regional Planning Progress Update

The most recent regional planning cycle for the region was completed with the release of an Integrated Regional Resource Plan (IRRP) and the supporting Appendices in November 2021. The plan is to monitor load growth in the Kingston area and trigger development work, and ultimately construction, for a new 230 kV transformer station, when required; and meanwhile, also continue development of energy efficiency programs for the area. In the meantime, distribution load transfers will be implemented to help balance load growth between the transformer stations in the Kingston area.

The plan also recommends a new transformer station in Belleville at the site of the existing Belleville TS. In addition, the plan makes recommendations regarding the scope of replacement of transmission facilities at their end-of-life, and some minor station upgrades to improve supply in the area.

Prior to the development of the IRRP, a Scoping Assessment Outcome Report and Terms of Reference for the Peterborough to Kingston Region IRRP was developed and posted following a two-week public comment period.

The next planning cycle will begin again in 2025, unless there is sufficient load growth or an event that requires it to begin earlier.
