PacWave South has opened off the Oregon Coast, completing a major federal and state investment that gives Oregon the nation’s first pre-permitted, utility-scale, grid-connected open-ocean facility dedicated to testing wave-energy technology.
Located approximately seven miles southwest of Newport, the Oregon State University facility provides four offshore testing berths where developers can place full-scale wave-energy converters into Pacific waters and connect them to the regional electrical grid. The site covers approximately two square nautical miles and can accommodate as many as 20 devices with a combined testing capacity of 20 megawatts.
The opening follows more than a decade of site selection, environmental review, federal licensing, engineering and construction. Oregon State selected the Newport-area location in 2013 after evaluating coastal sites, including Reedsport, and considering ocean conditions, commercial fishing activity, marine habitat, port access and routes for bringing electrical cables ashore.
Much of PacWave South’s infrastructure is hidden beneath the Pacific. Four subsea power and data cables run approximately 12 miles from the offshore testing area to shore facilities near Seal Rock. The cables allow developers to transmit electricity and operating information from experimental equipment at sea, providing researchers with continuous performance data while testing machinery under open-ocean conditions.
Each of the four testing berths can support up to 5 megawatts of generating capacity. Electricity produced by future wave-energy converters can travel through the cable network to PacWave’s Utility Connection and Monitoring Facility before entering the regional electrical system. An arrangement involving Oregon State University and the Bonneville Power Administration provides for the purchase of as much as 20 megawatts of electricity produced during testing.
PacWave South is operational, although wave-energy converters have not yet begun generating electricity at the facility. Its 20-megawatt rating represents available testing capacity rather than electricity currently entering Oregon’s power supply. Developers will install their own technologies at the site as individual projects advance to offshore testing.
Federal funding supplied much of the money behind the project. The U.S. Department of Energy awarded Oregon State University $35 million in 2016 for the design, permitting, construction and operation of PacWave South, while Oregon contributed approximately $3.8 million. Federal investment connected with PacWave’s development, siting and construction has since approached $150 million.
The Bureau of Ocean Energy Management issued Oregon State University a research lease for the offshore site in 2021, establishing the first wave-energy research project in federal waters off the West Coast. The Federal Energy Regulatory Commission also issued Oregon State a 25-year license to construct and operate the facility following an extensive federal environmental review.
The completed permitting creates an offshore testing location capable of hosting several major categories of wave-energy equipment without requiring individual developers to establish separate research sites. Technologies eligible for testing include point absorbers, attenuators, oscillating water columns and hybrid systems designed to convert ocean movement into usable electricity.
The work now shifts from construction to deployment and testing. Developers will be able to measure electrical output, mechanical reliability, maintenance requirements and equipment durability while exposing full-scale machinery to the conditions that have challenged wave-energy development for decades. Pacific storms, saltwater corrosion, powerful currents and prolonged mechanical stress remain among the engineering obstacles facing equipment intended for commercial ocean operation.
PacWave South also expands Newport’s established marine research sector. Offshore testing requires vessel operations, technicians, engineers, equipment deployment and recovery, environmental monitoring, maintenance crews and data analysis, adding wave-energy research to the scientific and maritime activity already concentrated along Oregon’s central coast.
Commercial and recreational fishing interests were among the groups involved during the project’s lengthy planning process. The offshore site was positioned over predominantly sandy seafloor and away from heavily used fishing reefs. Fishing is not universally prohibited within the PacWave area, although deployed equipment, anchors, mooring systems and monitoring instruments can restrict navigation around active testing operations.
Southern Oregon residents are unlikely to experience a direct change in electricity costs or power availability from PacWave South. The facility is a research installation centered near Newport rather than a commercial generating station supplying communities in Josephine, Jackson, Klamath, Douglas or Curry counties. Any broader economic activity involving other Oregon ports, manufacturers or marine-service companies would depend upon future expansion of wave-energy technology beyond the testing stage.
PacWave South joins PacWave North, a smaller Oregon State University testing area approximately two nautical miles offshore near Newport. PacWave North operates in state waters and supports smaller-scale research without a connection to the electrical grid, while PacWave South was constructed for larger equipment and utility-scale testing in federal waters.
With the offshore cables, shore facilities, federal licenses and grid connection now in place, PacWave South moves into its intended role as an operating research facility. The first deployments will bring full-scale wave-energy machines into the Pacific and begin producing the performance data needed to measure their electrical output, durability and operating costs under actual ocean conditions.
