Staying Connected: New Transmission Line in Southwest Ontario – March 31, 2021

The IESO has requested that Hydro One initiate the work and engagement activities to develop a new transmission line between Lambton and Chatham. This new line is one more step that the IESO is taking to support the rapid agricultural growth in the Windsor-Essex and Chatham areas.

A webinar will be held on March 31 at 2:00 pm with IESO Interim President and CEO Terry Young to provide an overview of this project and answer any questions from the broader community.

The IESO has been engaging with local communities and regional stakeholders since 2018 to better understand and plan for the future electricity needs in the near-, medium- and long-term periods – particularly in the areas west of the city of London. Given the rate of growth, the implementation of a variety of solutions is already underway including investments in conservation programs, innovative pilot projects, sector studies and recommendations for new infrastructure.

This project is the result of long-term electricity planning underway in the area, and is one component of a broader plan to be announced in the coming months to support growth in the region.

To learn more about this announcement, please join this Staying Connected webinar - New Transmission Line in Southwest Ontario - on March 31 at 2 p.m. (The webinar will be recorded and available afterward.)

Is the IESO applying a climate lens in planning out its projects? If yes, how so?
Also, how can municipalities partner with the IESO and other utilities to reduce their GHG emissions when implementing large-scale projects in rural areas, given the electricity grid there is just adequate?

Thank you for your question, Huda. Studies are being undertaken to examine future options for fuel mixes with multiple potential solutions to supply challenges and these may include DERs and storage solutions. Hear more about our response in the event recording at 25:34.

Will a grid scale generation facility be needed at Lambton GS location to offset the net nuclear reduction in the GTA?
Is a grid scale energy storage option at Lambton GS location a benefit for the grid long term given the demand increase forecasts?

Refurbishments at Darlington and Bruce are being looked at. We do expect to have the resources available to address challenges around refurbishments, but at the end of the decade we are starting to see that new resources will be needed. Hear more about how community-based resources may play a future role in the event recording at 28:41.

Thank you for your question, Tim. The Windsor-Essex IRRP Addendum Study and West of London Bulk Study are still underway; another virtual meeting will be held in the coming weeks to cover how we are investigating potential non-wires alternatives going forward to meet those needs. Hear more about this in the event recording at 31:06.

Thank you for your questions, Wilfred. The IESO is highly supportive of the involvement of Indigenous communities in Ontario’s electricity sector. Our goal is to build the capacity of Indigenous people and communities, and create opportunities in support of fair and equitable participation in the electricity sector.

As part of the identification of need for a new transmission line from Lambton to Chatham, the IESO has engaged local Indigenous communities and offered opportunities to discuss the outcomes of our recent studies, and incredible growth in electricity demand in the region. We look forward to those ongoing conversations, including with the HCCC.

Hear more about this in the event recording at 33:33.

For example, will fibre-optic cable be included?

Thank you for your questions, Marshall and Carol. We have not specifically spoken with the transmitter about tower and other technical specifications to accommodate more wires in the future, but it is an important consideration given the high growth in this area. These details will come out of the transmitter’s detailed design at the later stages of development. Hear more about this in the event recording at 32:34.

Thank you for your question, Carol. Hydro One will initiate work, engagement and activities, including seeking Environmental Assessment and Leave-to-Construct approvals for this next stage of development. As part of that process, Hydro One will engage with the local community, including Indigenous communities, and consult where appropriate before a final route is selected and announced.

Hydro One has indicated costs for the project may range between $210 million to $290 million depending on the preferred route.
