Low cost offshore wind survey technique based on environmental DNA (eDNA) analysis

Specialist consultancy and service provider with a sole focus on supporting renewable energy projects.


25 years of experience advising on offshore wind projects, with expertise from site-selection and consenting to decommissioning / repowering.


International team of >500 headquartered in Scotland.

Business profile

Natural Power has been operating in the renewable energy sector for over 25 years. Its OWGP-funded project was focussed around demonstrating the validity of a survey method for offshore wind consenting – environmental DNA (eDNA) sampling. By analysing small fragments of DNA found in seawater, this method reveals data on the abundance and distribution of fish species around offshore wind farms. Collecting such information is an important part of environmental impact assessments and compliance monitoring that support the consent of new offshore wind farms.

OWGP-funded collaborative project looking to demonstrate environmental DNA (eDNA) sampling as a survey method around offshore wind farms, enabling lower-cost, faster and more precise environmental data for consent applications.


Compared with traditional trawl surveys, eDNA sampling requires only small samples of seawater; reducing damage to habitats and eliminating the need for specialised vessels.


Reveals information on spatial distribution of different fish species around offshore wind farms.

Rather than trawling fish with nets from specialised vessels and manually recording different species, eDNA sampling requires only samples of seawater to be collected from above the seabed. This offers a non-intrusive sampling method, improving the reliability and precision of offshore wind environmental data collection, from a wider range of vessels which can be combined with other site-based surveys and activities.

profile

OWGP grant funded around 50% of the project costs with Natural Power collaborating with NatureMetrics and EDF Renewables.

Successful trial of eDNA demonstrated several benefits over traditional methods, and generated novel insights that could improve understanding of offshore wind’s local environmental effects.

Results of the trial presented and made publicly available in November 2023, with the long-term aim to gain regulatory approval for the method.

Before

Natural Power was already a well-established provider in the renewable energy sector, having supported numerous offshore wind projects throughout their lifecycle. Natural Power was seeking partners to trial environmental DNA (eDNA) as a cheaper and more efficient alternative to fish trawls during offshore wind environmental impact assessments and ongoing compliance monitoring.

What they say

As we rapidly transition to renewable energy sources to help tackle climate change, supply chain resources are under pressure so there’s never been a greater need for new technology and practices that help to maximise resources. This study, made possible in part due to OWGP Innovation Grant Funding; demonstrates that eDNA-based surveys offer a market-ready solution to optimise consenting phase surveys of offshore wind site development, as well as ongoing monitoring and targeted mitigation strategies. Regulator and stakeholder acceptance of eDNA methods for use in offshore baseline setting and monitoring will now be a key step towards accelerating and improving environmental monitoring for future offshore wind development.
