Construction begins this week – and will end in early 3Q17 – on the Lambton-St. Clair upgrade project, which involves both ITC Michigan and Ontario-based Hydro One, an ITC spokesperson told TransmissionHub on May 2.
The existing lines connect the St. Clair substation, which is located adjacent to the St. Clair power plant in East China Township, Mich., to Hydro One’s Lambton Transformer Station #2, which is located in Courtright, Ontario, the spokesperson said, noting that the project is “one of many points on the border that exemplify the interconnectedness of the American and Canadian power systems.”
The project involves an upgrade from the existing static ground wire to optical ground wire (OPGW), which combines the grounding and communication functions, and it “is an example of the ongoing commitment to reinforce infrastructure not just in Michigan but across an international border,” she said.
The project involves about four miles of 230-kV line and about three miles of 345-kV line, the spokesperson said.
The 230-kV line will go back into service in late 2Q17, followed by the 345-kV line in early 3Q17, she said.
“It is our policy not to disclose financial details for specific projects, but the Lambton-St. Clair project is an example of ITC’s ongoing commitment to the operational efficiency and reliability of Michigan’s high-voltage transmission grid,” the spokesperson said of the project’s total estimated cost.
Since 2003, the company has invested more than $3.4bn in capital project maintenance and transmission infrastructure improvements in Michigan, improving the reliability and safety of the equipment, while ensuring its ability to meet new energy demands, she added.
ITC has secured permits from the Michigan Department of Environmental Quality and U.S. Army Corps of Engineers, and is working with the Michigan Department of Transportation for a permit, the spokesperson said.
“Additionally, ITC and Hydro One have been working closely with the U.S. and Canadian Coast Guards and Ontario Provincial Police to coordinate” the St. Clair River crossing, she said.
Furthermore, she noted that Hydro One has received approval from the National Energy Board in Canada.
ITC is a Fortis (NYSE:FTS) company.
