Canada's Independent Electricity System Operator (IESO) has requested that Hydro One continue to expand electricity infrastructure in southwestern Ontario by building a 230-kV double circuit transmission line, which, if approved by the Ontario Energy Board, would be in service by 2028. A new transmission line between Hydro One’s Lambton transformer station and its Chatham switching station would provide electricity to support rapid agricultural growth in the Windsor-Essex and Chatham areas.
“This transmission line is another step in a multi-faceted planning approach to ensuring electricity is available now and into the future for Ontario’s fastest-growing region in terms of electricity demand,” said Terry Young, Interim president and CEO of the IESO. “Over the last number of years, we have engaged with communities in the region, seeking their input so we can better understand how to develop cost-effective solutions to meet their energy needs.”
As a result of extensive planning, analysis and community engagement, the IESO is expecting agricultural electricity demand in the Windsor-Essex and Chatham areas to grow from roughly 500 MW today to about 2,000 MW by 2035 -- equivalent to adding a city the size of Ottawa to the grid. The IESO’s studies also concluded that a Hydro One transmission line is the most cost-effective and timely next step to supply the region.
The IESO has been engaging with local and regional stakeholders to better understand electricity needs in the area to support economic development and job growth. Feedback has shown there is strong community interest in an integrated solution of both traditional infrastructure and innovative options to meet electricity needs. Further action will be required to address the pace of demand growth in the area and additional steps will be identified in IESO studies to be released this spring.
