Overview
Updated 1 hour agoThe 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.

Historical Context
3 moments from history that rhyme with this story — and how they unfolded.
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.
The lease expired in 2017 and the project was abandoned - no turbine was ever installed.
Cape Wind showed a single offshore energy project could be stalled for over a decade by permitting and legal fights.
PacWave South's pre-permitted model lets device developers skip the years-long permitting path that killed Cape Wind.
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.
The Portuguese wave farm shut down within months and its machines never returned to commercial service.
Pelamis's collapse showed wave energy developers cannot survive without sustained testing infrastructure and reliable funding.
PacWave South gives wave developers the real-world, grid-connected testing venue and permitting relief that Pelamis never had.
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.
EMEC hosted the first wave and tidal devices to feed a UK grid and established testing norms for the industry.
EMEC became the template for marine energy test sites worldwide - including PacWave South.
PacWave South brings EMEC's proven pre-permitted, grid-connected model to US continental waters for the first time.
