Forecasting and Planning
Regional planning for the Windsor-Essex electrical region was completed in April 2025. This engagement initiative provided Indigenous communities, municipalities, customers and interested parties with an opportunity to offer input for consideration into the development of the 2025 Windsor-Essex Integrated Regional Resource Plan (IRRP). A Regional Infrastructure Plan (RIP) led by Hydro One will be initiated next, as part of the regional planning process.
Technical Working Group - A Technical Working Group, consisting of E.L.K. Energy Inc. (E.L.K.), Entegrus Powerlines Inc. (Entegrus), Enwin Utilities Ltd. (ENWIN), Essex Powerlines Corporation (EPL), Hydro One Networks Inc. (Hydro One) and the IESO will continue to stay in touch on the implementation of recommendations and timing of the next regional planning cycle. To stay informed on future electricity planning activities for this region, subscribe to receive updates on Windsor-Essex.
All comments and enquiries in this engagement initiative can be directed to engagement@ieso.ca.
