The Lambton Generating Station was a coal-fuelled power plant located on the St. Clair River near Corunna, Ontario, delivering up to 950 MW of power to the grid. It is owned by Ontario Power Generation. The plant previously had a total generating capacity of 1,976 MW, prior to the permanent shutdown of generating units 1 and 2 (of four) in October 2010. The remaining units were shut down in September 2013. It was connected to the power grid via numerous 230 kV lines, and also had two interconnections with Detroit Edison and ITC Transmission via a 230 kV line (Lambton-St. Clair #1) and a 345 kV line (Lambton-St. Clair #2). It is located almost exactly across the St. Clair River from Detroit Edison's St. Clair Power Plant in East China, Michigan. The facility had three 168-metre (551 ft) smokestacks, one of which was equipped with flue-gas desulfurization units, commonly called "scrubbers", to remove sulfur oxide. Emissions from scrubbers at the Lambton station could be seen for over 16 km, although with the scrubbers operating properly, these plumes likely had over 90% less SO2 compared with other coal-fired stations without scrubbers. On November 22, 2016, it was announced that Ontario Power Generation was no longer looking at alternative uses for Lambton Generating Station, and that the facility would be decommissioned in 2017. It was definitively closed in 2020. Demolition work is in progress and should last 2 years. On February 12, 2022, the majority of buildings at Lambton Generating Station, including the three large stacks, were imploded.

Mooretown is a community in the Township of St. Clair, Ontario, Canada, located on the east bank of the St. Clair River. It was first established as Sutherland's Landing.Mooretown gained in prosperity during the 19th century as a port of call for sail born vessels requiring assistance to pass "The Rapids" where steamboats driven by cord wood stacked on Mooretown's piers could be towed up river into Lake Huron. The original Scottish settlers established a church at Sutherland's Landing (now between Mooretown and Courtright) which was then moved to Mooretown in the 1860s when the oak logs of the original structure rotted out. The 1860s structure was struck by lightning in 1918 having been built of local timber with a copper clad steeple known to mariners as a navigation point. The 1919 replacement structure is now on the Moore Museum's grounds having been preserved by artist Christine Anne Wingfield-Brandon. The structure retains the steeple bell from the original Sutherland's Landing Church.Mooretown served as a regional center for salt mining and oil refining before these industries move to neighboring communities. In the 19th century Mooretown was a regional seat with a considerable population with hotels and a municipal seat, it exists today as a quiet and distinctive community.

Belle River Power Plant is a major coal-and-natural gas-fired power plant owned by Detroit Edison, a subsidiary of DTE Energy. It is located in St. Clair County, Michigan, on the peninsula formed by the St. Clair and Belle rivers. The plant was built across M-29 from the St. Clair Power Plant in East China, Michigan, and shares the coal delivery terminal with it. The Belle River plant also shares cooling water from the St. Clair River with its sister plant. Five oil-fueled internal combustion generators (named IC1, IC2, 3, 4, and 5) were built in 1981, with a total output 13.75 megawatts. Coal-fired unit 1 of the Belle River plant was completed in 1984, followed by a similar unit 2 in 1985. Each unit has a nameplate capacity of 697.5 MWe, however the coal-fired plant as a whole generates 1260 MWe all year around. In 1999, three peaker natural-gas fired turbines (named 12-1, 12-2, and 13-1) were added, with a total name-plate capacity of 256 MWe. Belle River is Detroit Edison's third largest producer of electricity. The power plant has a significant impact on the local economy, employing many residents. The Lansing Board of Water and Light owns a small portion of the power plant and buys electricity from DTE during peak demand periods. The plant will be fully converted to natural gas by 2026.

The Saint Clair Power Plant was a major coal- and oil-fired power plant owned by DTE Electric, a subsidiary of DTE Energy.

It was Detroit Edison's second largest power producer. The power plant has a large impact on the local economy, employing about 300 workers. The plant shut down in May 2022.
