Waldinger – Alliant Deere Run Solar

Located in Cedar Rapids, IA

Shive-Hattery and our design-build partners worked with Alliant Energy to provide customers with the ability to purchase blocks of solar power that will become bill credits for 20 years.

The design for this project began in 2020 and construction was completed in 2024. Work included two 480V services to two transformers and switchgear for centrally located inverters. The system is 4.5 MW (AC) and 5.599 MW (DC) with 10,268 bifacial modules.

This project involved two key components. The first focused on the installation of ground-mounted solar, and the second component focused on a utlity scale Battery Energy Storage System that was adjacent to the utility substation that feeds to the solar project. The BESS project included 5.0MW/10.0MWH battery capacity. Two 2500 KVA pad mounted transformers were utilized to connect the BESS to the 12,470 volt three phase utility. The BESS was utilized to absorb access power for the solar project during peak production and load demand events.

The components on the electrical system were not constructed by Shive-Hattery. Shive-Hattery was a designer of the project and provided over 40 percent of the design services for the project.
