Eng, MBA Director of Engineering Milton Hydro Distribution Inc. 8069 Lawson Rd. Milton, ON, L9T 5C4 Dear Mr. Pereira: Subject: Regional Planning Status In reference to your request for a regional planning status letter, please note that Milton Hydro Distribution Inc. (Milton Hydro) belongs to GTA West and Kitchener-Waterloo-Cambridge-Guelph (KWCG) Regions. Both regions are in Group 1. A map of all planning regions and groups, and a list of Local Distribution Companies (LDCs) in each region is attached in Appendix A and B, respectively. GTA West Region GTA West Region is divided into two sub-regions: Northern (referred to as Northwest GTA) and Southern Subregions. An Integrated Regional Resource Planning (IRRP) Report for Northwest GTA Subregion was completed in April 2015. The IRRP Report s recommendations included a plan to provide additional supply capacity to Milton and southern Halton Hills area, currently served by Halton TS. Based on the current load forecast, a new transformer station (Halton TS #2) will be required by 2020 to meet load growth in Milton Hydro service area. The budgetary estimate for the new TS is $29M, and Milton Hydro may be required to make a capital contribution, which will be determined when Milton Hydro formalizes the request for a new transformer station. In addition, Milton Hydro will have to undertake distribution investments in order to integrate the new TS to supply load from this station. Some of the other needs, such as restoration needs on circuits T38B/T39B, identified in the Northwest GTA IRRP will be addressed through the Independent Electricity System Operator s (IESO) bulk system planning process, or in the next regional planning cycle. The rest of the needs are expected to have no impact on Milton Hydro. A Scoping Assessment for Southern Subregion was completed in September 2014. Milton Hydro is supplied from Palermo TS, Tremaine TS, and Glenorchy MTS in this Subregion. The study team determined that the needs identified in this subregion can be addressed by wires approach by Hydro One and relevant LDCs or by the IESO s bulk system planning process. The needs in Southern Subregion are expected to have no impact on Milton Hydro.

The RIP will provide a consolidated wires-only plan to meet the needs in the region for the next 10-year planning horizon. Hydro One will formally notify your organization prior to initiating the RIP phase for this region. KWCG Region Milton Hydro is an embedded LDC served by Fergus TS in KWCG Region. An IRRP Report for this region has been completed in April 2015. The RIP process for KWCG Region is planned to begin by the end of Q2 2015. This RIP will provide a consolidated wires-only plan to meet the needs in the region for the next 10-year planning horizon. Hydro One will formally notify your organization prior to initiating the RIP phase for this region. Two transmission projects have been identified in this region to address the near- and medium-term needs in this region: the first being the Guelph Area Transmission Reinforcement (GATR) project, and the second being the installation of switches on circuits M20D and M21D. Execution of the first project is already underway while the second in the project development phase. One component of the GATR project involves the installation of two load interrupter switches on 230 kv circuits D6V/D7V at Guelph North Junction. The switches will minimize the impact of interruptions to Milton Hydro customers in the event of the loss of both circuits D6V and D7V. The investments associated with the GATR project are proposed as a network pool cost, and there is no cost implication for Milton Hydro. Hydro One looks forward to working with Milton Hydro in executing the regional planning process. Please feel free to contact me if you have any further questions. Sincerely, Ajay Garg, Manager Regional Planning Coordination Cc: Bing Young, Director System Planning, Farooq Qureshy, Manager System Planning (Central and East),
