Pacific Marine Energy Center South Energy Test Site (PMEC-SETS)

You are here

The Pacific Marine Energy Center South Energy Test Site (PMEC-SETS) is an Energy Department-funded, grid-connected, full-scale test facility for wave energy conversion technologies—the first of its kind in the United States. The site is currently being developed off the coast of Newport, Oregon, by faculty and staff in the College of Earth, Ocean and Atmospheric Sciences (CEOAS) and the Northwest National Marine Renewable Energy Center (NNMREC) at Oregon State University (OSU). The Energy Department announced the selection of the OSU-led team to develop the facility in December 2016 and initial operation is expected to begin in summer of 2021.

The test facility will be able to accommodate up to twenty wave energy converters (WEC)—devices that convert wave energy into electricity—in four separate test berths simultaneously. Each berth will have a dedicated transmission cable and the site will be prepermitted for a variety of WEC technologies. WECs are one range of devices in the Energy Department’s research and development portfolio that generate energy from the ocean. Others include tidal and current energy converters as well as ocean thermal energy conversion technologies. These devices are part of a collective suite of marine and hydrokinetic (MHK) technologies that convert the energy of waves, tides, and river and ocean currents into electricity.

The test site will provide a grid-connected platform for advanced testing of utility-scale wave energy converters in a high-energy, open-coast environment. Transitioning wave energy technologies to full-scale commercialization requires both in-water tests of performance and efficiency and extended demonstrations of reliability, operations, and maintenance in an open-ocean, grid-connected operational site. Improved environmental monitoring systems coupled with a 25-year Federal Energy Regulatory Commission (FERC) operating license will help expedite the testing process at reduced costs for technology developers. The ability to more quickly and cost-effectively test devices and demonstrate iterative design improvements will allow technology developers to more rapidly improve performance, drive down costs, and attract investment and financing for future projects.

MHK technologies are still at relatively early stages of development. Fundamental scientific and engineering challenges of generating power from dynamic, low-velocity and high-density waves and currents while surviving in corrosive ocean environments present significant barriers to advancing the MHK industry. The Energy Department’s Water Power Technologies Office (WPTO) supports testing infrastructure to enable technology development by industry at multiple scales. The PMEC-SETS site will enable technology developers to prove device performance in dynamic wave environments for long periods of time-thereby, demonstrating technical viability, determining methods for cost reduction, and advancing technologies toward cost-effective power delivery and commercial readiness.

Frequently Asked Questions

Where will the site be located?

Roughly six nautical miles off the Oregon coast, southwest of Newport, Oregon, in the Pacific Ocean.

What did the competitive selection process entail?

In 2013, the Pacific Marine Energy Center and the California Wave Test Center were both selected as Energy Department Funding Opportunity Announcement (FOAs) awardees. These FOAs allowed projects to begin design and permitting of deep-water, high-energy, open-ocean test facilities with the ability to test multiple devices and arrays simultaneously. A second competitive FOA was released for final design, final permitting, constructio,n and initial operations in August 2016, and the Pacific Marine Energy Center was selected in December 2016.

What types of wave energy converters can be tested?

Testing of most WEC types will be allowed, including point absorbers, attenuators, oscillating water columns, and hybrid devices.

What is the relationship between MHK and wave energy converters? 

Wave energy converters are one of a range of devices that the Energy Department is researching to generate energy from the ocean. Other examples include tidal and current energy converters as well as ocean thermal energy conversion technologies. These devices are collectively referred to as MHK technologies. 

What is the expected depth range for the test site?

The test site will be in water between 65 to 78 meters (213 to 256 feet) deep.

How many WECs will be able to be tested at the site at once?

The test site will have a maximum capacity of 20 utility-scale WECs and will have the ability to test multiple arrays of wave energy devices simultaneously. The maximum power output from the test site will be 20 megawatts.

How long will the FERC license and associated Bureau of Ocean Energy Management lease be for?

Twenty-five years, unless relicensed for a longer duration in order for the facility to stay compliant with The Energy Policy Act of 2005.

Types of Wave Energy Converters

Point absorbers: Floating or submerged structures with components at or near the ocean surface that capture energy from the motion of waves, which drives a generator. Point absorbers may be fully or partly submerged. They typically have a relatively small surface area compared to the wave length.

Attenuators: Structures that respond to the curvature of the waves rather than the wave height. These WECs may consist of a series of semisubmerged sections linked by hinged joints. As waves pass along the length of the WEC, the sections move relative to one another. The wave-induced motion of the sections is captured and used to drive a generator.

Oscillating water columns (OWC): Structures that are partially submerged and hollow, open to the sea below the water line and enclosing a column of air on top of a column of water. Waves cause the water column to rise and fall, which in turn compresses and decompresses the air column. This air is allowed to flow to and from the atmosphere via a turbine, which usually has the ability to rotate regardless of the direction of the airflow.

Hybrid: WEC types that utilize use two or more of the above-listed technology types. For example, some devices that are the relative size and shape of a point absorber may generate power through movements that resemble an attenuator. Another example is a class of devices with moving masses that are internal to a hull with no external moving parts exposed to the ocean. The vertical-axis pendulum WEC is such a device; it has a structural hull that contains all moving parts; inside, a pendulum rotates due to the kinetic energy of the ocean waves.
