Description
The Marine Energy Test Center Area (META) consists of eight pre-consented (non-grid connected) sites in and around the Milford Haven Waterway, for testing devices, sub-assemblies, and components. The site aims to help developers deploy, de-risk and develop their marine energy technologies. META is supported by the European Regional Development Fund, through the Welsh Government, and the Coastal Communities Fund. The test site is part of Pembroke Dock Marine, a collaborative project aimed at developing marine energy in Pembrokeshire.
There are five Quayside Sites, which are accessible via existing Pembroke Port infrastructure.
- Site 1 - Carr Jetty: 9m depth; 71 ha area; mud/sandy mud seabed; maximum tidal currents <1 knot 0.5 m/s.
- Site 2 – Mainstay Quay: 6m depth; 0.87ha area; mud/sandy mud seabed; maximum tidal currents <1 knot 0.5 m/s; limited wave exposure.
- Site 3 – Ferryside: 1m – 6m depth; 59ha area; mud/sandy mud seabed; maximum tidal currents <1 0.5 m/s; very limited wave exposure.
- Site 4 - Quay 1: 8m depth; 2.39ha area; accommodates devices up to 164m length; mud/sandy mud seabed with manmade causeway of rubble and rock; maximum tidal currents <1 0.5m/s; very limited wave exposure.
- Site 5 – Criterion Jetty: 18m depth; 0.48ha area; mud/sandy seabed; maximum tidal current <1 m/s; higher wave exposure.
There are three open water test sites, which are within or adjacent to the Milford Haven waterway and provide real-sea testing.
- Site 6 – Warrior Way: Supports scaled and micro tidal devices (2m – 20m depth; 9.3ha area; mixed sediment seabed; tidal stream resource - 1.5 m/s.
- Site 7 – Dale Roads: Supports scaled and full-scale wave energy converter (WEC) devices (6m – 11m depth; 19.56ha area; mixed sediment seabed with rock and reef; wave resource - 0.6m Hs (annual mean), 9-second peak period (annual mean), 5.68 Hmax.
- Site 8 – East Pickard Bay: Supports scaled and full-scale wave energy converter devices (10m – 29m depth; 123ha area; predominantly sand seabed with small areas of hard substrate; wave resource – 1.52 Hs (annual mean), 9-second peak period (annual mean), 13.6 Hmax).
Location
Milford Haven Waterway, Pembrokeshire, Wales
Licensing Information
META is a pre-commercial, pre-consented test facility, that has consents required to install an agreed ‘envelope’ of device types and activities at it’s 8 sites. Relevant licenses and consents include:
- Marine License from Natural Resources Wales (Marine and Coastal Access
- Seabed lease from the Crown Estate
- Marine Works License from Milford Haven Port Authority
- Town and Country Planning Consent from Pembrokeshire County Council
A list of all licenses can be viewed at Natural Resources Wales.
Project Progress
META acquired all relevant permissions and became operational in 2021.
Previous deployments:
- Porpoise Power – Oscillating hydrofoil tidal energy converter

- Installed in January 2023 and removed March 2023; Installed January 2024 and removed March 2024
Key Environmental Issues
Benthic habitat is considered a sensitive feature within the Warrior Way and Dale Roads test sites. META has conducted detailed benthic habitat mapping at these sites so seabed devices / components can be micro-sited away from sensitive benthic habitats.
Tidal devices must have minimum 2m blade tip clearance to sea surface to avoid impact on diving bird Little Grebe.
There is a requirement to design out fish and bird ingress in to wave devices.
A full Environmental Impact Assessment (EIA) was carried out to understand the potential impacts of the project during construction, operation and decommissioning stages. Topics assessed included:
- Marine sediment and water quality
- Natural heritage, benthic ecology, marine mammals, fish and shellfish, ornithology, terrestrial and coastal ecology
- Seascape and landscape
- Shipping and navigation
- Archaeology and cultural heritage
- Tourism and recreation
Device-specific pre-installation: Monitoring Plans must be produced and approved by the regulator prior to installation to supplement information in the EIA Report (as appropriate).
Post-installation monitoring: Device-specific Environmental Monitoring Plans must be produced and approved by the regulator prior to installation.
