Modular RivGen Test in Millinocket Maine
In January 2023, ORPC deployed its new low-flow Modular RivGen hydrokinetic power system in Maine's Millinocket Stream followed by a second device in May 2023. These devices were deployed at One North, a renewable energy hub and industrial park located at a former paper mill site and managed by local nonprofit Our Katahdin. The project goal was to demonstrate the system’s potential to provide resilient baseload power for uses like electrical vehicle (EV) charging and critical infrastructure. The project has provided an opportunity for teams at top U.S. research universities and national labs, including University of Washington and Sandia National Laboratories, to conduct research through the U.S. Department of Energy’s TEAMER program.
The width of the two devices when connected was about 51 ft, while the width of Millinocket Stream at the project site is approximately 100 ft wide. Considering that recreation use (e.g., paddlers, fishing vessels) was possible during testing, the devices' corners were marked by four buoys, with one additional buoy marking the location of an upstream anchor.

Site Characteristics
Geographic characterization for the project location:
- Open Ocean: Main body of ocean, not enclosed or partially enclosed by land
- Coastal: Open water near the coast, spanning between land and shelf boundary
- Enclosed Bay: water that is partially surrounded by land, with a mouth open to larger water
