Service Provided: MTC provided construction materials testing and observation throughout the site. In-place nuclear density testing was performed to evaluate subgrade conditions for site grading and road construction. Pile testing was conducted to assess the tension and pullout capacity of the solar foundations, verifying that they could withstand wind loads and structural demands. Additional testing supported the installation of AC and DC lines, ensuring proper backfill and compliance with project specifications.
Project Description: The Riverstart III Solar Park, located near Modoc in Randolph County, Indiana, is a 100 MW utility-scale solar development completed in early 2025. As part of EDPR NA’s expanding Indiana portfolio, it generates enough clean energy to power over 19,000 homes and supports the region’s grid reliability. Standout features include extensive photovoltaic arrays, multiple access roads, and both AC and DC electrical collection systems—all integrated with pollinator-friendly landscaping to support local ecosystems
