Project Summary


This is a preliminary mapped developed through a partnership with Michigan Energy Options and the Western Upper Peninsula Planning and Development Region. This map displays the capacity for creating photovoltaic solar generation projects on brownfield sites located in Houghton and Marquette Counties.

This interactive map reflects the findings of a localized, preliminary study on the solar potential of brownfield sites in two regions of Michigan’s Upper Peninsula.


Brownfields are sites in which the redevelopment or reuse of the property may be complicated by the presence or perception of contamination. The map sites and examines the solar potential of contaminated lands and retired landfills and mines in the Marquette and Houghton/Hancock regions.


All sites have been identified through discussion with local officials and available online data provided by the Michigan Department of Environmental Quality. Data reflects site areas that are mostly free of existing structures or tree growth. All data is approximated and is not intended to replace the need for a detailed, site-specific assessment for solar development.


Attributes are broken down as follows:

1. Sun Symbol: Brownfield sites that have been examined for their solar potential. Features highlighted include:

- Potential Solar Capacity: This number reflects the potential size of a solar PV system that can be installed on a particular site based on its acreage. This is based on an average of 4 acres per Megawatt of installed solar (DC).

- Utility Service Territory: The utility that serves the area of the site’s location.

- Proximities to Infrastructure: Given their inherent prior use, a benefit of redeveloping brownfields with solar generation is their typical convenience of location in regards to existing infrastructure. For siting solar, we focus on four key details: Distance to Transmission, Distance to Substations, Distance to Graded Roads, Distance to Urban Centers.

- Ownership: Public lands labeled by city, county or state. Utility-owned lands labeled by utility. Privately-owned lands noted as private.
