Fabricators have completed work on the pontoons and chassis for a second tidal river power system, called RivGen, for Ocean Renewable Power Co. of Maine. Its first system has been generating electricity since October 2019 in the Kvichak River in Igiugig, Alaska, about 240 miles southwest of Anchorage.

Company chief engineer Ryan Tyler says lessons learned during the building and installation of the first RivGen device were applied when his team worked with vendors to improve quality while reducing fabrication complexity and cost of the second RivGen unit.
