Our Story

Cadens started in this venture with an exhaustive market search to purchase a small 25-35 kW unit for the Rome Mill. Acquiring a used turbine runner proved unsuccessful. Turbine suppliers seemed reluctant to engage and sell a low head, micro hydro unit, but eventually we received quotes of $90,000-$120,000 for a well-known 18” Francis design (wicket gates, runner w/shaft) – no generator, no controls, no installation. A startup quoted $150,000 F.O.B. San Francisco, for an unproven design, now defunct – no installation. None of the available options were economically feasible and demonstrated that the turbine runner was the single most expensive component but the other custom components were not economical either. It also became clear that proven hydropower theory and modern computational tools should be used to design the system for highest efficiency. CFD and FEA are critical in designing high-efficiency components to be robust for system longevity.
