Modular RivGen Power System
ORPC’s Modular RivGen Power System harnesses energy generated from river currents and is designed for integration into existing or new infrastructure such as electric vehicle charging stations, hydroelectric facilities, irrigation canals and bridges, piers, breakwaters, and flood controls systems. Designed for lower-velocity sites, the Modular RivGen Power System can be adapted to both utility-scale and distributed energy uses. The device utilizes ORPC’s patented cross-flow turbine generator unit, designed and constructed using advanced composites. It’s engineered to enhance hydrodynamic performance while withstanding harsh marine conditions.
Each device has one turbine, which can currently produce up to 7 kW of energy during peak flow. The array of two devices can produce 14 kW of power in total. ORPC is continuing to evaluate and test design efficiencies so that a single Modular RivGen device can eventually produce 18 kW, or 36 kW for an array of two devices. For context, 18 kW is enough to power essential appliances and systems in a small- to medium-sized home.
