The primary power system facilities serving this region are Pickering NGS and four 500 / 230 kV transformers at Cherrywood TS. Load in south Durham Region is almost 900 MW, growing at about 1% to 1.5% per year.

Transformation relief required for Cherrywood TS once Pickering NGS retires. Local supply reliability in the area also needs improvement. Transformation relief required for Cherrywood TS once Pickering NGS retires. Local supply reliability in the area also needs improvement.

for the region was about 770 MW (summer peaking) in 2015
to continue developing as targets for the greater golden horseshoe are pursued
in the GTA East Region since 2014.This group consists of the Independent Electricity System Operator (IESO), Hydro One Networks (Transmission and Distribution), Veridian Connections Inc, Whitby Hydro Electric Corporation and Oshawa PUC Networks Inc.
and Oshawa-Clarington based on the types of needs identified:
– Needs in the Oshawa-Clarington sub-region were assessed by a Hydro One led Local Planning Working Group in 2015. This report is now complete and can be found on Hydro One’s website – An Integrated Regional Resource Plan (IRRP) for the Pickering-Ajax-Whitby Area is currently underway. This plan will assess the needs and recommend integrated solutions to meet the identified needs.
the foundation for continued planning to address future needs as they arise.

this sub-region was completed by Hydro One in May 2015
is recommended for the area to address near- term capacity needs
Oshawa Hydro, Hydro One Distribution and Hydro One Transmission is under development for this transformer station.
Near-Term Needs
transformer capacity required to be in-service by 2018 to support urban and Greenfield growth in Pickering
for meeting restoration criteria for rare failure events
20
Options Considered for Meeting Capacity Needs 1. A new transformer station near the community of Seaton and reinforcement of existing line 2. New 27.6 kV distribution feeders from other transformer stations 3. A combination of the above

Details of Option 1-Reinforcement of Existing Circuits
Existing tower type: single circuit Approximate portions of circuit to be reinforced (dependent on the preferred site)
Options Considered for Restoration 1. Do Nothing, because the risk does not justify the cost. 2. Establish distribution infrastructure and process for transferring load between distribution stations during these unlikely failure events. 3. Install remote control motorized switches on the 230 kV circuits to isolate the faults from the rest of the Region’s system.
25
Status of Near-Term Needs and Options
– Economic analysis comparing the three different options is complete, and a new 230/27.6 kV transformer station which is
– Given the near-term nature of the need, implementation of the recommendation is under development
– Economic analysis is underway to compare the cost and benefits
transfers – Results of this analysis to be shared at the next LAC meeting

Are there other items that should be considered? – strategic growth plans, community energy plans, economic development discussions, update to Official Plans?
