We’re planning now to meet your community’s future electricity needs

Demand for electricity in the South Nepean area has almost doubled since 2002. Over the next twenty years, electricity needs in your community are expected to more than double once again due to planned residential and commercial development.

In order to ensure that South Nepean has the power to grow, Hydro Ottawa Limited (Hydro Ottawa) and Hydro One Networks Inc. (Hydro One) are planning for new electricity facilities to strengthen the electricity system that serves your community.

Draft ESR Available for Public Review

The Draft Environmental Study Report (ESR) is now available for public review. The ESR is a document that describes the Class Environmental Assessment (EA) activities that have been undertaken for the project, including a description of the project, environmental features, potential environmental effects and mitigation measures.

The ESR is available for a 45 day public review period that ends on April 26, 2019, during which time the project team invites you to review the document and to provide any comments or questions.

The ESR is available to download and view online here. The ESR is also available to review as a hard copy. It can be found by visiting one of the seven places listed below and requesting to review the document.

Project Description and Map

The Power South Nepean project proposes:

  • a new municipal transformer station (MTS) that would be owned and operated by Hydro Ottawa and located within the study area shown on the map below; and
  • to rebuild the existing Hydro One 115 kilovolt (kV) transmission line to a new double circuit line with 230 kV capacity. This transmission line would connect the new MTS to the 230 kV line south of West Hunt Club Road, while continuing to supply other stations in the area.

Map Date: November 2018


Determining the need for new facilities

The need for new electricity transmission facilities in the South Nepean area was identified by the Independent Electricity System Operator (IESO), Hydro Ottawa and Hydro One as part of the Integrated Regional Resource Plan (IRRP) for the Ottawa area. The IESO leads the IRRP process with industry partners across different regions in Ontario. The Integrated Regional Resource Plan identifies the region’s unique electricity reliability needs and considers conservation, generation, transmission and distribution, and innovative resources to meet these needs.

The electricity needs of the Ottawa area over the next 20 years and recommended solutions are identified in the IESO’s Ottawa Area Integrated Regional Resource Plan (April 28, 2015) and its Appendices. The IRRP was developed based on consideration of planning criteria including technical feasibility, reliability of the electricity system, cost for electricity ratepayers, and seeking to maximize the use of existing electricity infrastructure, where possible. To learn more about the IESO and regional supply planning in the Ottawa area, please visit:  http://www.ieso.ca/en/get-involved/regional-planning/east-ontario/ottawa-sub-region

In addition, Hydro One’s Greater Ottawa Regional Infrastructure Plan (December 2, 2015) was developed in partnership with local distribution companies in the region , including Hydro Ottawa, in accordance with the requirements of Ontario’s Transmission System Code. This plan identifies investments in transmission facilities, distribution facilities, or both, that should be developed and implemented to meet the electricity infrastructure needs within the Greater Ottawa Region.
