Our Story
Cadens began with a simple mission: bring affordable, small-scale hydropower to sites long ignored by traditional turbine manufacturers. When we searched for a 25–35 kW unit for the Rome Mill, we hit a wall—quotes were sky-high, options were limited, and none were practical for low-head applications. The takeaway was clear: the market lacked scalable, cost-effective solutions for micro-hydro.
From the Ground Up: How Cadens Is Reinventing Hydro
Founded in 2011 by Randal Mueller and Dan Gieschen, Cadens LLC was built to change that. By merging time-tested hydropower principles with modern engineering tools—like CFD, FEA, and large-format 3D printing—we developed efficient, cost-effective turbine systems tailored to each site. Early support from the U.S. Department of Energy, The BREW, and WERCBench Labs laid the foundation for our Rome Mill Test Facility and a new era in small hydro innovation.
Where Others Saw Limits, We Engineered Solutions
Today, Cadens is transforming untapped waterways into dependable clean energy with our TurbineBuilder software and custom 3D-printed components. Whether it’s a farm, factory, or rural community, we make low-head hydropower viable—where others said it wasn’t.
