Regional Electricity Planning - Kitchener Waterloo Cambridge Guelph

Forecasting and Planning

Regional electricity planning for the Kitchener-Waterloo-Cambridge-Guelph (KWCG) region was completed in May 2021 with the release of a long-term electricity plan – Integrated Regional Resource Plan (IRRP). A Regional Infrastructure Plan (RIP) led by Hydro One is expected to be completed by mid-to-late-2021. This engagement initiative provided communities and stakeholders with an opportunity to offer input for consideration into the development of the IRRP.
