How “The Big Blue Cart” Revolutionized Battery Installation for Alliant Energy’s Decorah Project

In the heart of Decorah, Alliant Energy’s cutting-edge battery storage project is a testament to innovation and efficiency. The Decorah Battery Project features state-of-the-art energy storage technology housed in several robust containers.

Innovative Energy Storage Solutions

The project’s central component includes racks that accommodate twelve batteries each, ranging from compact units to those towering well over head height. According to Rick Zimmerman, Alliant Energy Senior Strategic Project Engineer, the challenge was clear: “We needed to make the installation process not only easier but also safer.”

The Role of RackLift™ in Efficient Installation

Enter RackLift™, an essential tool powered either by a hand crank or an electric drill, which has proven invaluable in the installation process. To streamline the operation, Alliant Energy and RackLift™ engineers collaborated to design a custom loading cart specifically for this project.

Custom Loading Cart: A Game Changer

The result was the Big Blue Cart, which significantly alleviated the physical strain on contractors by lifting 3,660 pounds off their shoulders. With each of the 360 lithium-ion modules weighing around 100 pounds and roughly the size of a desktop computer, the Big Blue Cart made a remarkable difference.

Mike McArthur, Project Manager at Eilertson Inc. (Alliant Energy’s installation contractor), emphasized the impact: “I can’t imagine loading all those modules without the RackLift™. Once we got the hang of it—unpacking a battery, cranking it up to the right height, and sliding it into place—we significantly sped up the process.”

Enhanced Efficiency and Future Applications

The ease of use was not lost on the technicians. “The RackLift™ has transformed the installation process,” noted McArthur. “They can unpack and install a battery in the time it takes to unpack the next one, allowing them to work in a smooth, efficient rhythm.”

Sarah Martz, Alliant Energy Manager of Distribution Engineering, reflected on the project’s success: “We’ll certainly look to replicate what we’ve learned here in future battery projects.”

A New Era of Energy Storage

The 2.5-megawatt, 2.922-megawatt-hour battery system will function as a crucial “electron bank,” storing excess solar power for a community known for its high concentration of customer-owned generation.

By leveraging innovative tools like the Big Blue Cart, Alliant Energy is setting new standards for efficiency and safety in energy storage solutions.
