Over the past year, an Oregon State University-led team made significant progress on the construction of the PacWave South test facility. PacWave South will be a grid-connected and pre-permitted wave energy testing facility off the Oregon coast. 

The team conducted tests to determine sediment conditions on the seafloor where cables will be laid to connect the test site to the shoreside Utility Connection and Monitoring Facility (UCMF). Evaluating and understanding seafloor conditions are critical for the team as it prepares to lay and bury subsea cable over the next year. The team also made significant progress on construction of the UCMF. Construction began in early 2023, and the team has completed the building frame and the road leading up to the facility. Located near the PacWave South facility and test site, the UCMF will allow researchers to monitor the data collected at PacWave South and distribute the energy generated by test devices to the local grid.

The team also began the manufacturing process for the cables that will connect the test site to the UCMF. The team developed power and data cables that will transmit generated power and information on device performance and environmental monitoring back to the UCMF. This information will help developers better understand why their devices are performing a certain way, how to improve them, and how to respond to conditions devices may face in the open ocean.

Meanwhile, researchers from the National Renewable Energy Laboratory completed the PacWave Anchoring and Mooring Study, which evaluates options for mooring system components that developers are expected to need at PacWave.
