US Aggregates Supplies Material to Multiple Indiana Renewable Energy Projects

US Aggregates has been the primary supplier for nearly all renewable projects located in White, Jasper and Starke Counties since 2019. The wind farms consist of many regular and what is now known as ‘Super Turbines’ built to capture the energy generated by the wind. Solar farms consists of many solar panels strategically aligned to capture as much of the sun’s light throughout the day. The energy captured by these farms is then used to provide power to the Northeastern Grid of the United States. Wind and solar farms produce what is considered ‘green energy’ because they generate power while emitting very little greenhouse gases into the atmosphere. The wind farm projects include Rosewater and Crossroads I & II. The solar farm projects include Crossroads, Twin Lakes, Dunn’s Bridge I & II, Calvary and Stark.

The aggregate supplied to the renewable energy farms have constructed more than 350 miles of roads between all farms, built inverter stations, switchyards and laydown yards. To date, more than 1 million tons of aggregates have been supplied to the nine solar and wind farms since 2019 with more still on the way.

The bulk of the material supplied to these farms are INDOT 53’s and INDOT 73’s used as a base for the roads, as these products meet the Indiana Department of Transportation (INDOT) requirements for road construction. Fine aggregates called Screenings and INDOT 2’s were also included in the base mix in the roads for their thermal resistivity qualities. The energy that wind and solar farms produce transfers underground through electrical lines. The thermal resistivity of our materials helps reduce the loss of energy as it flows underground to the switchyards. INDOT 8’s are also being supplied to allow for proper drainage to help prevent flooding during storms and continued ease of access.
