ITC seeks public input on $21.8B Midwest power transmission expansion
ITC Michigan requests public input on a 50-mile power line connecting Eaton and Livingston counties as part of MISO’s $21.8 billion regional transmission expansion.
ONEIDA TOWNSHIP, MICHIGAN — ITC Michigan is seeking public feedback on a proposed 50-mile power transmission line connecting Oneida Township in Eaton County to Cohoctah Township in Livingston County. This is part of a regional energy infrastructure expansion.
The Novi-based transmission company needs to secure a Certificate of Public Convenience and Necessity from state energy regulators before moving forward with the project. This is one component of the Midcontinent Independent System Operator’s plan to enhance electricity reliability across the Midwest.
Regional Expansion Project Details
In 2024, MISO approved the second phase of its infrastructure initiative, which includes 3,631 miles of transmission lines to create a 765-kilovolt backbone throughout the region. The $21.8 billion plan aims to improve energy reliability across multiple states.
ITC’s proposed line would connect the company’s existing Oneida substation to a new facility planned for Livingston County. The transmission company operates the energy transmission system for much of Michigan’s Lower Peninsula.
Regulatory Requirements and Community Engagement
Michigan law requires transmission companies seeking to construct lines longer than five miles with voltage exceeding 345,000 volts to obtain state approval, according to ITC Michigan President Charles Marshall, who spoke with reporters on Tuesday.
“Under Michigan law, any transmission company looking to build a line that’s longer than five miles with a voltage of 345,000 volts or more must seek a Certificate of Public Convenience and Necessity from state energy regulators,” Marshall explained.
The regulatory process requires ITC to submit a construction plan to the Michigan Public Service Commission, distribute the plan to affected municipalities, offer meetings with their highest elected officials, and conduct public meetings in each community where transmission lines would be built.
Public Input Process Underway
Before filing their application with the public service commission, ITC must identify a preferred route along with alternative options. Marshall noted that community engagement is essential for gathering information and refining proposed routes.
Ben Tirrell, a regional manager for local and government affairs for ITC, said community discussions on the project began with local officials and community leaders in 2025. The company continues seeking input from residents and stakeholders as it develops its formal proposal.
The transmission line project faces ongoing opposition from some landowners along the proposed corridors, though ITC maintains that public feedback will help shape the final route selection and design specifications.
