I asked BRAVE search engine this…
when did the planning start for the copperton hign power lines begin in michigan ? and why?
The reply ….
Planning for the Copperton Projects began several years prior to 2026, as part of the Midcontinent Independent System Operator's (MISO) Long-Range Transmission Planning (LRTP) process. The specific segment for Michigan, known as Project 32, was approved by the MISO Board of Directors in December 2024 as part of the larger LRTP Tranche 2.1.
The planning was initiated to address several critical grid needs:
Grid Reliability and Resilience: To strengthen the electric transmission system, reduce the risk of blackouts, and improve resilience against extreme weather.
Renewable Energy Integration: To enable the integration of cheaper renewable energy sources, such as wind and solar, which are currently hindered by transmission limitations.
Growing Demand: To accommodate increasing electricity demand driven by factors such as data center development, electric vehicle adoption, and the electrification of homes.
Economic Efficiency: To unlock cleaner, lower-cost power and provide ratepayers with value estimated to be two to three times the cost of the infrastructure investment.

How will Project 32 impact local property values?
The impact on property values from Project 32 (part of the Copperton Projects) is a major concern for affected landowners, with different effects depending on property type and proximity:
Directly in the right-of-way:
Landowners whose properties are crossed by the 345-kV lines will have easements placed on them, restricting structures, vegetation, and land use. An attorney representing affected farmers noted that ITC's option agreements have been criticized as "raw deals" that allow the company to use the rest of a property as a construction staging ground without additional compensation, and that signing could lock in rights that limit future compensation if the voltage or number of lines increases later.
Nearby residential properties:
Residents along the proposed routes have raised concerns about depressed property values, lost views, and the visual impact of 100-foot towers. Studies on high-voltage transmission lines generally find a 5–10% decline in residential property values within close proximity (within ~200–600 feet), diminishing with distance. One South Dakota PUC study found 84% of surveyed residents near HVTLs believed their property value was negatively affected, with an average estimated decline of about 10%.
Agricultural land:
Farmers face operational disruptions — interrupted drainage tiles, irrigation systems, and forced changes to planting patterns around towers — which can reduce crop yields and diminish lease value for the affected parcels.
Broader area:
Some residents also worry that the new transmission capacity will enable increased development pressure (e.g., data centers) in the surrounding area, which could shift the local housing and land market in unpredictable ways.
It's worth noting that the Michigan Public Service Commission, when it approved the routes in 2025, acknowledged these concerns but proceeded, citing the demonstrated need for the infrastructure. Landowners who object can pursue compensation through eminent domain proceedings once the project moves forward.
