Coos Bay OPT Wave Park



OPT is proposing to develop a utility-scale, commercial wave park in North America at Coos Bay, Oregon. The planned size of this park is up to 100 megawatts, and it is expected to be the largest wave energy project in the world when it is completed. The wave park will be located approximately 2.7 miles off the coast of Oregon, west of the towns of Coos Bay and North Bend. The Coos Bay OPT Wave Park will utilize OPT’s next generation PB500 PowerBuoys®. The wave park will consist of up to 200 PowerBuoys, 20 undersea substations, and a sub-marine cable to deliver the electricity generated from this wave park into the grid served by the Pacific Northwest power grid. Each PB500 PowerBuoy is planned for a maximum sustained generating capacity of 500 kilowatts.

OPT will be engaging the project stakeholders in a collaborative process similar to the process used at Reedsport which led to OPT’s application for a full FERC license for that project. We believe that using the foundation begun at Reedsport further demonstrates our commitment to collaborative, responsible development of wave power which maximizes benefits to all stakeholders. This “do it right” approach demonstrates our long-term commitment towards environmental stewardship of coastal resources.

Proposed Site of the Coos Bay
OPT Wave Park



The Coos Bay OPT Wave Park will supply 275,000 megawatt hours annually to the grid based on the wave resource at this location. This community-based renewable energy project will provide enough power for 24,900 homes1. Electricity generated by OPT’s clean, renewable PowerBuoy system will displace 140,250 tons of carbon dioxide each year the project is in operation2. This is the equivalent of removing 29,000 cars off the road annually3.
