The River Mersey has been at the heart of the fortunes of Liverpool City Region for hundreds of years, from the first ferries across it and the world’s first commercial wet dock to today’s Port of Liverpool. How we use this great natural asset has always evolved.
Now, in a time of climate crisis, we are turning to our great river once more to harness its natural power to secure a greener, cleaner, and more prosperous Liverpool City Region for this and future generations. We have one of the UK’s largest tidal ranges and a long history of research into tidal power. We can harness this heritage and the power of our tides to generate a plentiful, reliable supply of clean, green energy, powering hundreds of thousands of homes.
Starting on 1 October and running until 15 November 2024, this section will contain links to an online survey so you can have your say about our plans to create the world's largest tidal power scheme. It will also contain further detailed information about the scheme.
Frequently Asked Questions
Who is leading the project?
The Mersey Tidal Power Project is being developed by the Liverpool City Region Combined Authority (LCRCA).
The LCRCA is a local authority represented by the elected Metro Mayor and elected councillors from the councils of Halton, Knowsley, Liverpool, St Helens, Sefton and Wirral. The LCRCA is the strategic decision-making body for the Liverpool City Region.
The LCRCA committed to the development of Mersey Tidal Power in its 2022 Plan for Prosperity which sets out the LCRCA policy framework up to 2035.
The Project is also included in the LCRCA Five Year Climate Action Plan and the LCRCA Spatial Development Strategy.
What are you consulting on?
We are consulting with the public to share an early idea of what the project could look like and understand any concerns or questions you have as we progress into future development stages.
The Mersey Tidal Power Project consists of the following main components:
- A tidal range barrage located within the channel of the Mersey Estuary which contains:
- A Power Generation System with control equipment and a sub-structure housing turbines with an expected electrical output of up to 1 GW;
- A Hydro Control System (including sluice gates);
- A Marine Navigation System (including locks);
- A Power Export System;
- Onshore operational facilities including maintenance, stores and office buildings; and
- Associated rock armour and breakwaters.
- An onward grid connection to a National Grid substation; and
- Utilisation of the surrounding port facilities during the construction phase in addition to other potential associated developments which may support the construction phase.
We are continuing to develop our understanding of our river and costal environment, what a scheme would look like, and how we can balance the benefit of a renewable marine energy scheme into the natural environment.
What are the next steps after consultation?
Following the close of this consultation, the project team will review all responses received and consider feedback provided, alongside ongoing ecology studies, engineering design, ground investigation and stakeholder engagement to refine our proposals further. We will present our refined proposals for comment at a further round of statutory consultation, which we intend to hold in 2025. Feedback received to the statutory consultation will help us shape our final proposals before we submit our application for a DCO.
Who makes the decision on granting permission for the Mersey Tidal Power Project?
As the Mersey Tidal Power Project will consist of the construction of a generating station with a capacity of over 50MW, the project is classified as a Nationally Significant Infrastructure Project (NSIP) under section 14(1)(a) the Planning Act 2008.
This means that one of the main types of permission we will be seeking to obtain is a Development Consent Order (DCO) from the Secretary of State for Energy Security and Net Zero.
The Secretary of State for Energy Security and Net Zero will make the final decision on whether to grant a DCO for the Mersey Tidal Power Project. The decision will be made after the examination of the application for a DCO, following which the Planning Inspectorate will provide a report and recommendation to the Secretary of State to help inform their decision.
More information on the DCO process is available at: infrastructure.planninginspectorate.gov.uk
Public Events
We are consulting on our proposals for a tidal barrage between the Wirral and Liverpool. This would use our greatest asset, the River Mersey with its large tidal range, to generate clean, green electricity to power homes in the city region for more than a hundred years.
Come along to our public events where you can learn more about the Mersey Tidal Power Project and meet the team. Your views are important in helping to shape our proposals.

Please note this timeline is indicative and may be subject to change
2024 to 2025
Further project development
Following the initial (Autumn 2024) consultation, we will consider all feedback received alongside our ongoing engineering design and environmental assessment work, and ongoing stakeholder engagement to further develop our proposals.
2025
Statutory consultation
We will consult with stakeholders, local communities and landowners on our refined proposals and Preliminary Environmental Information Report, in accordance with the requirements of the Planning Act 2008.
2026
Submission
Once we have finalised our proposals after considering all feedback received at statutory consultation, we will submit our application for a Development Consent Order to the Planning Inspectorate. This will include a Consultation Report which will demonstrate how consultee feedback has shaped our proposed scheme.
2026 to 2027
Examination
The Planning Inspectorate will carry out an examination of our application, which usually takes up to 6 months. During this time, hearings will be held, representations can be submitted by interested parties, and questions posed to us.
2027
Decision
After the Planning Inspectorate has made a recommendation, the Secretary of State for Energy Security and Net Zero will decide on whether to grant a Development Consent Order.
2028
Ready for construction
We will then construct the tidal barrage and associated infrastructure using a staged approach to minimise impacts to river users, the environment, and local communities.
