PacWave South opens as first grid-connected wave energy test site in continental US

PacWave South opens as first grid-connected wave energy test site in continental US

Built World

Ten-year, $150 million federal effort puts wave energy testing on the US grid

August 26th, 2026: PacWave South opens as first continental US wave energy site

Overview

Updated Aug 27

The first wave energy test site connected to the continental US electric grid opened off Oregon's coast this week. PacWave South took a decade to permit and build, backed by nearly $150 million in federal investment.

The site is pre-permitted, so developers can test devices like point absorbers and oscillating water columns without securing their own permits. No machines had arrived as of the opening; funding delays have slowed developers. The infrastructure for wave energy's real-world trial is in place.

Why it matters

Wave energy could provide steady, round-the-clock power, but proving it works requires real-world grid testing. PacWave South removes the biggest barrier: years of permitting.

  1. PacWave South opens as first continental US wave energy site

    Latest Milestone

    Facility opens, but no test devices have arrived yet; developers cite federal funding delays.

  2. PacWave South connects to the grid

    Infrastructure

    The facility is wired into Central Lincoln People's Utility District's network.

  3. Energy secretary approves PacWave opening

    Regulatory

    PacWave passes a required 'go/no-go' review at the Energy Department before opening.

  4. Construction of PacWave South completed

    Milestone

    The offshore site and its cable system to shore are finished in early 2025.

  5. FERC issues PacWave South operating license

    Regulatory

    Federal Energy Regulatory Commission issues 25-year license, pre-permitting most wave devices.

  6. DOE selects Oregon State to build wave energy test site

    Selection

    US Department of Energy chooses the OSU-led team to develop PacWave South.

Scenarios

1

Wave Energy Devices Deploy and Power the Grid

Likely Resolves by Sep 1, 2027

Discussed by: PacWave director Dan Hellin and DOE officials expect testing to start within months of the opening

Developers secure federal funding and deploy their converters in PacWave South's four berths. Power flows through the site's cables to Central Lincoln's grid. The first devices will test performance, reliability, and cost under real ocean conditions - the data wave energy needs to attract private investment.

2

Federal Funding Delays Keep PacWave South Idle

Possible Resolves by Q2 2028

Discussed by: AP News and OPB reporting on developers facing federal funding delays

Device developers cannot secure the federal funds needed to build and ship their converters. The site stays connected to the grid but generates no power. PacWave's pre-permitting advantage means little if no one can afford to test.

3

Wave Energy Nears Commercial Viability

Uncertain Resolves by End of 2030

Discussed by: DOE's Water Power Technologies Office expects the site to move wave energy toward commercial readiness

Successful testing at PacWave South shows wave energy can generate power reliably at acceptable cost. Private investment follows, and the first commercial wave energy project outside a test facility is announced in the US. This would echo how early test sites helped wind and solar bring costs down.

Historical Context

3 moments from history that rhyme with this story — and how they unfolded.

2001-2017

Cape Wind (2001-2017)

Developer Jim Gordon spent 16 years pursuing permits for 130 turbines in Nantucket Sound off Cape Cod, Massachusetts. The project faced lawsuits from opponents including local tribes and utility interests, and never secured a buyer for its power.

Then

The lease expired in 2017 and the project was abandoned - no turbine was ever installed.

Now

Cape Wind showed a single offshore energy project could be stalled for over a decade by permitting and legal fights.

Why this matters now

PacWave South's pre-permitted model lets device developers skip the years-long permitting path that killed Cape Wind.

2004-2014

Pelamis Wave Energy (2004-2014)

Edinburgh-based Pelamis built the world's first offshore wave machine to feed a national grid off Portugal in 2008. The company went bankrupt in 2014 after a decade of funding struggles and technical setbacks.

Then

The Portuguese wave farm shut down within months and its machines never returned to commercial service.

Now

Pelamis's collapse showed wave energy developers cannot survive without sustained testing infrastructure and reliable funding.

Why this matters now

PacWave South gives wave developers the real-world, grid-connected testing venue and permitting relief that Pelamis never had.

2004-present

European Marine Energy Centre, Orkney (2004-present)

The European Marine Energy Centre (EMEC) opened in Scotland's Orkney Islands in 2004 with pre-permitted, grid-connected berths for wave and tidal devices. It has since hosted hundreds of deployments and became the global standard for marine energy testing.

Then

EMEC hosted the first wave and tidal devices to feed a UK grid and established testing norms for the industry.

Now

EMEC became the template for marine energy test sites worldwide - including PacWave South.

Why this matters now

PacWave South brings EMEC's proven pre-permitted, grid-connected model to US continental waters for the first time.
