Atlantic Marine Energy Test Site (Full Scale)

The Atlantic Marine Energy Test Site (AMETS) is being developed by Sustainable Energy Authority of Ireland (SEAI) to facilitate testing of full scale wave energy converters in an open ocean environment.

AMETS will be located off Annagh Head, west of Belmullet in County Mayo and will be connected to the national grid.

The test site is an integral component of Ireland’s Ocean Energy Strategy and is being developed in accordance with the national Offshore Renewable Energy Development Plan  (OREDP).

The site will be focused on wave energy and will provide two separate test locations at various depths of water to allow for a range of devices to be tested.

It is envisaged that the test site will provide a grid connected national test facility, to which full scale wave energy converters could be coupled during their final stages of pre-commercial development.  

The test site will comprise of both onshore and offshore components.

Currently offshore there will be two test areas:

  • Test Area A will be at 100m water depth and will be  located some 16km out from Belderra Strand; Test Area A will be 6.9 km2 (2.02 nautical square miles).
  • Test Area B will be at 50m water depth and will be located 6km from the strand. Test Area B will be 1.5 km2 (0.44 nautical square miles).

The onshore element comprises a small substation which will be constructed close to the landing point of the offshore cables on Belderra Strand.

The substation site will be 2 acres.

Build of the substation is planned for 2018.  

The test sites will be accessible via Frenchport Pier.

The proposed test site in Belmullet will focus on wave powered technologies. The test site is not yet in operation for developers but SEAI can offer interested developers a  suite of detailed information such as live met-ocean data measurements, numerical wave modelling reports including wave propagation and wave energy assessments, offshore site investigations including vibrocores and multi-beam surveys.

Real-time observations from the Atlantic Marine Energy Test Site Data Dashboard wave buoys known as Belmullet Inner (Berth B) and Belmullet Outer (Berth A) include:

  • Wave Height
  • Wave Period

The Atlantic Marine Energy Test Site data dashboard is a set of graphs and tools that display real-time performance indicators related to the wave climate at the Belmullet Inner (Berth B) and Belmullet Outer (Berth A) sites. Historical data is also available.  

Observations gathered from the wave measurement buoys include:

  • Significant Wave Height (metre)
  • Average Wave Period (secs)
  • Mean Wave Direction (degree)
  • Maximum Wave Height (in measured period)
  • Wave Spectra


SEAI are currently undertaking a review of the AMETS and would appreciate feedback from all ocean technology developers who have an interest in utilizing the site.

We have compiled a high-level report on the current status of the site, the wave and wind resources at the location, and an outline of data collected at AMETS to date.

Also included is a survey which we would appreciate your feedback on. The results of the survey will determine the way forward for AMETS.

Any floating wind technology specifications provided will be included in an upcoming Environmental Impact Assessment Report (EIAR), which is being compiled as part of an application for a lease/licence for floating wind technologies at AMETS. The EIAR will accompany the consent application which is due to be submitted in 2022.

The lease/licence application will use an envelope approach, which would enable a range of floating offshore wind technologies to be installed. To allow for a multitude of technologies to be included in the EIAR a range of technology specifications will be screened. If you wish your technology to be included in the EIAR, please indicate this by providing the relevant specifications in as much detail as possible in the accompanying questionnaire.

AMETS already has a lease in place which covers the deployment of wave conversion devices, and interest is also sought from anyone interested in deploying such devices at the site.

We appreciate your interest in AMETS and your time spent in reviewing the report and filling in the questionnaire.
