Solar Project Update: North Rock

A new year means new construction for our North Rock Solar Project. The 50-megawatt project in Fulton, Wisconsin is part of our Clean Energy Blueprint, a strategic roadmap to accelerating renewable energy and reducing carbon emissions. Once complete, the project will generate enough clean, low-cost energy to power approximately 13,000 Wisconsin homes.

Habitat Happenings

We’re big fans of creating pollinator-friendly habitats in and around our solar projects, and our North Rock site is no exception. Seeding was completed this fall, and vegetation growth throughout the project is making great progress.

North Rock SolarTo create a perfect pollinator playground, we utilize a specially selected, Wisconsin Department of Natural Resources-approved mix of grass and seed varieties designed to promote a safe and healthy environment. It includes prairie natives such as slender wheatgrass, sideoats grama, perennial ryegrass and little bluestem. This low-growth grass mix reduces the need for frequent mowing and maintenance.

These varieties of native vegetation attract pollinators, including bees, butterflies, moths and other beneficial wildlife populations.

Construction Continues

Crews are currently installing pilings, the metal columns which anchor the solar array structures to the ground. Once pilings are placed, crews will begin to install the racking systems that will support the solar panels.
