OPG is advancing early-stage exploration of potential new electricity generation at its Nanticoke and Lambton sites.
The company is providing $500,000 in early Growth Readiness Funding to municipalities to support local planning and engagement.
These sites could play a role in helping meet Ontario’s growing energy needs with potential new power generation, including nuclear.
OPG is advancing the exploration of new electricity generation potential at its Nanticoke and Lambton sites in southwestern Ontario.
This summer, Minister of Energy and Mines, Stephen Lecce, announced $500,000 in early Growth Readiness Funding to Haldimand County, home to Nanticoke, and St. Clair Township, home of the Lambton site, to support the municipalities as they assess development opportunities, including potential nuclear generation.
In addition to these sites, OPG continues to explore the potential for new generation at its Wesleyville site in Port Hope, where a new large-scale nuclear development is being proposed.
With Ontario’s electricity demand forecasted to increase significantly by 2050, these three sites could play an important role in meeting the province’s future energy needs.
Previously, the 900-acre Nanticoke site hosted the Nanticoke Generating Station, which was North America’s largest coal-fired generating station, operating from 1972 to 2013. The plant was safely demolished in 2019.
Meanwhile, the 1,200-acre Lambton site was formerly home to the Lambton Generating Station, a coal-fired facility capable of producing 1,976 megawatts of electricity. The four-unit station began operating in 1969 and was shut down in 2013.
Both sites are already zoned for electricity generation, close to transmission infrastructure, and located in a region experiencing significant growth. They also offer the potential to reuse certain site features from previous operations.
OPG's Lambton site previously hosted the Lambton Generating Station, which operated from 1969 to 2013.
“OPG understands the critical importance of engaging with communities early when considering siting new generation infrastructure,” said Nicolle Butcher, OPG’s President and CEO. “This funding will ensure Haldimand County and St. Clair Township have the capacity to engage fully on behalf of its residents as we work collaboratively to explore generation options for these sites.”
The Growth Readiness Funding will be used at the municipalities' discretion to support their assessment of potential development opportunities. This could include assessing municipal infrastructure upgrades needed to support new generation. OPG will continue to build respectful, collaborative relationships with Indigenous Nations, while understanding rights impacts and pursuing potential opportunities for future partnerships, reflecting OPG’s commitment to ensure local First Nations benefit from new developments.
As part of this early phase of engagement, OPG will continue working with Indigenous Nations, municipal leadership, and local stakeholders to better understand community priorities and perspectives on potential generation technologies.
OPG will also continue discussions with the municipality and Indigenous Nations about potential economic and social benefits that could flow to host communities.
