America’s first major wave energy testing site just opened off the Oregon coast, and it turns the ocean’s rise and fall into electricity sent straight to the grid

Over the past year, federal energy policy has seen dramatic shifts. The administration canceled billions of dollars in clean energy grants, repurchased offshore wind leases, and raised barriers to renewable development.

Yet against this backdrop, one of the most significant ocean energy milestones in recent memory cleared federal review. Tucked inside a complex regulatory landscape, a pioneering marine project successfully navigated federal scrutiny to unlock a vast source of clean power.

A clean energy milestone in an unlikely political moment

Surviving federal review was far from guaranteed. After President Trump returned to office in 2025, the project faced a mandatory “go/no-go” evaluation at the Energy Department requiring personal sign-off from the energy secretary.

While the government spent nearly $4 billion repurchasing offshore wind leases and canceled hundreds of green grants, marine energy carved out a unique exemption.

Project Director Dan Hellin confirmed that approval arrived last summer, clearing the way for grid connection this summer.

The contrast with broader policy remains stark. While the government spent nearly $4 billion repurchasing offshore wind leases and canceled hundreds of green grants, marine energy carved out a unique exemption.

Administration officials set marine hydrokinetics apart from offshore wind, viewing wave energy as a distinct political category. That distinction allowed this offshore testing facility to move forward while the broader sector faced headwinds.

What PacWave South actually is—and why it matters

Developed by Oregon State University with nearly $150 million in Department of Energy investment dating back to 2016, the facility serves as a utility-scale proving ground.

Rather than generating commercial power itself, the site allows developers to test full-scale wave energy converters under real ocean conditions.

Its primary advantage is its pre-permitted status. Normally, renewable energy startups spend years and millions navigating complex environmental permits before deploying hardware.

At this facility, that groundwork is complete. The site features four test berths accommodating point absorbers, oscillating water columns, attenuators, and emerging technologies simultaneously.

As Dan Hellin noted, full-scale open-water testing connected to an active grid has long been the primary bottleneck for the global marine energy sector. Providing this infrastructure removes decades of regulatory friction.

How wave energy converters actually work

The facility supports three main device types, each capturing ocean kinetic energy differently.

Point absorbers are the most common, using floating buoys that ride the ocean’s vertical movement. As waves move the buoy up and down, internal mechanical systems drive a generator to produce electricity.

Oscillating water columns rely on hollow, partially submerged chambers. Incoming ocean waves compress and decompress an enclosed air column, driving air back and forth through a top-mounted turbine that spins continuously in both directions.

Attenuators feature long, segmented floating structures positioned parallel to wave movement. Passing waves cause the hinged sections to flex against one another, driving mechanical systems that generate power.

Heavy-duty subsea cables running along the ocean floor deliver electricity from all three device types to shore.

The national security argument that changed the conversation

The decisive factor in securing federal approval was the Department of Energy’s framing of wave energy as a national security asset.

While federal officials opposed offshore wind development over potential military radar interference, they concluded wave energy converters are uniquely suited to provide low-profile power for defense applications.

Key applications highlighted by officials include powering remote ocean sensors, recharging autonomous underwater vehicles, and supplying resilient off-grid electricity to forward military bases.

By reframing marine energy as a defense priority, project leaders successfully protected the site’s funding and operating licenses.

An industry still waiting to prove itself

Despite the facility’s readiness, wave energy remains commercially nascent. Federal estimates suggest ocean waves could theoretically supply up to 57% of U.S. electricity needs, though capturing even a small fraction would meaningfully strengthen the national grid.

Developers currently face delays tied to federal funding uncertainties, making open-water testing a critical next step.

That context sets up a landmark moment: America’s first major wave energy testing site just opened off the Oregon coast, and it turns the ocean’s rise and fall into electricity sent straight to the grid.

Situated off Newport, PacWave Energy South is now officially operational, offering four berths linked directly to the continental U.S. power grid. Whether wave energy moves from promising concept to viable power source now depends on the pioneering devices that deploy in these Pacific waters.
