LCR pushes Mersey tidal power timeline back two years
A need for a government funding commitment has led Liverpool City Region Combined Authority to adjust its estimated planning application submission date from 2026 to 2028.
The Mersey Tidal Power project was floated by LCR Mayor Steve Rotheram in 2019. It would stretch across the river between Birkenhead and Liverpool and be capable of generating up to 1GW of energy – just under a third of what Sizewell C nuclear power station is set to create.
In addition to being a powerhouse of renewable energy generation, a tidal barrage on the River Mersey could provide flood protection and an active travel route between Liverpool and the Wirral. It would have an operational lifespan of up to 120 years, according to government data.
Ed Miliband, secretary of state for Energy Security and Net Zero, as well as other “senior figures” in government are supportive of the scheme, according to a Liverpool City Region Combined Authority report.
However, the drafting of a full business case for the project will require development funding – something the combined authority is working with various government departments to secure.
Because of that delay, the submission of a planning application is now set for 2028, with a financial investment decision for construction to come in 2030.
A lack of a funding decision has not dampened the city region’s ambition however. The project is continuing to phase four, with the combined authority being asked on Friday to approve continued procurement activity to move the scheme along.
Phase four includes sorting the social value potential of the project, crafting the full scope of project and ancillary assets, and the other consenting, engineering, project development, and commercial activity required to turn the scheme into reality.


We won’t even get bendy buses by 2028. Steve Rotheram is proof anyone can get elected in Liverpool in a serious city someone like him would never get reelected.

They dont have the tory excuse anymore. Remember when Starmer said he would put “Rocket boosters” up Liverpool. Not much evidence that anything has changed.
By Liverpool lacks ambition
We will probably have a reform govt in 2029 so we know what the excuse will be. Its all very predictable.

Someone needs to tell Steve that his white elephant is never going to get built. Give up and move up before wasting any more money!

Why does Steve Rotheram continously think that most people in the Liverpool City Region want this ugly monstrosity that will affect shipping, wildlife, and totally ruin the vista out to Liverpool Bay and the Irish Sea forever. He tries to sell this project by showing cyclists streaming across the river in glorious sunlight with avenues of trees to help the aesthetic, but that won’t fool the public. Why doesn’t he spend his time getting more practical things done that would do more for people in their daily lives, like building a proper tram network, expanding the Merseyrail network, or bring a ferry terminal back to New Brighton.

Nearly a year on from my comments about the barrage on 30th January 2025 in a PNW posting and nothing has changed….. apart from the planning application being put back two years or will that be two and twenty years!!!!!! There is still no detail as to where the barrage will go in the River Mersey. Will it be north of the Pier Head or to the south of the Pier Head? As soon as that information is known I suspect that the LCR will be deluged with objections from businesses and organisations that will be affected by it not least the Mersey Ferries! I still consider it to be Mayor Rotheram’s ‘flight of fancy’ that will hopefully never be built but which will of course be good business wise for all the consultants involved.

Starmer needs to put rocket boosters under himself.

An utter waste of time and effort designed to make the Mayor look busy. Worst of all, it’s laying uncertainty within the maritime industry and bringing caution to investment decisions. This fantasy may be good for Mr Rotherham’s politics, but it’s definitely bad for business. Time to kill it off.

This is a monumentally cool idea. I hope it goes ahead!

Is it viable. What’s the cost per mw.

Nothing ever happens
Nothing happens in LCR
The needle returns to the start of the song
The Echo prints CGIs like before
Steve Rotheram says no jam today, definitely jam tomorrow…

I stopped ready the Liverpool Echo years ago due to all the pie in the sky projects that they reported on. Which never ever materialised. I think I should give up reading PNW as I am still reading about pie In the sky projects E.G the Misery Mersey Barrage for example. If LCR & Ali Bongo Rotherham had any economic gumption about them. Then they should have courted private enterprise to gain the necessary funding. Rather than go cap in hand and beg Central government for handouts. I truly despair when I look at how regressed Liverpool has become in comparison to other large UK Cities.

I think this would be a very good scheme. Tidal power is very predictable. There are broader benefits beyond energy generation as stated above (flood protection, transport connection). Additionally, it would generate lots of jobs and potentially be another tourist feature. It is also a lot cleaner than nuclear. Depending on design, berths for docking can be included too. It can generate construction on both sides of the Mersey, which I am sure some folk would also moan about. I see this on both the bigger Liverpool and Manchester projects – people moaning about investing in the north, jobs, and home – and then complaining about when these things are planned or happen. As an aside, people were dead against the Eiffel Tower, Sydney Opera House, Golden Gate Bridge etc etc!

Liverpool i can truly say that your city has been once again side lined now under a Labour Government, remember that.

We will find out about aliens building the pyramids before this project gets any serious consideration
By Realist
For goodness sake concentrate on something more realistic and that will benefit the LCC as a whole- Waterfront there!!! full of potential or extend rail link or tram line to Airport ?

It’s perfectly sensible for Mayor Steve’s spinners to plan announcements on a grid so there’s always something to say, but every time they have to return to the Barrage Blag it just shows he has nothing new or even interesting to offer. It might even be better he just sticks to following Andy round and nodding. Expect more of this in the run-up to the May local elections.

A brilliant idea. Ignore the naysayers, get this built. It would be a vital piece of sustainable infrastructure in the LCR, provide shed loads of jobs and linked investments and put this wonderful city even more on the map than it already is. Think big Steve!
By Ox
My neighbour has a saying that if you put a pig in a Rosette as the Labour candidate the people of Liverpool would vote it in as long as it’s Labour. So many people say this won’t happen and it’s costing LCRCA in excess of £3m per year on studies and ecology surveys just to keep the project alive to get it to a DCO will cost even more and then there’s the construction costs £3.5bn
By Bob Dawson
Merseyside County Council looked at this in the 80s. Why doesn’t he just read the old reports in the city library to see why it won’t work and divert the cash to a tram network.
By Frank
Its never going to happen, I was involved in building an hydraulic model of the mersey tidal flows 30 years ago to access the concept of a barrage , the test results indicated numerous problems relating to silt, tidal flows, wild life, location, shipping, and more…pie in the sky except idea,except for the consultants ,money, money,money

There is more chance of a squadron of flying pigs going down the Mersey in formation with red and blue smoke shooting out of their little piggy arses than this happening in our lifetime!
By Paul Thompson
So this would basically cancel the Mersey ferry that is loved by all another example of MPs conjecturing up just what the city doesn’t need when a dedicated cruise terminal that would bring thousands of people and pounds into the city is he in collaboration with Southampton in some way to delay and stall a much needed cruise terminal for the city ? I just don’t get the hold up .

LCC planning team will reject it lol

Yet no transport links to a new stadium ? and Labour council then introduce parking restrictions …you couldn’t make it up.

The Mayors pending tray must spilling over by now, we’ve got the Barrage, Littlewoods Studios, Baltic Station, his 3 other stations at Daresbury, Carr Mill, and Woodchurch, Bendy Trams, Astra Zeneca discussions, etc

Nice plan, im sure it courld be great. In the meantime, something useful that people can use , like a train on tram to Liverpool Airport.

Can anyone point to any major investment driven by the mayor that has come to fruition? I can’t think of any, but am happy to be put right.

The land of “Make believe ” always tomorrow,trust me, sounds like a cue for a Steve Rotheram Musical.

Why not a dedicated mini bus service on the top of the barrage, it would help connect both communities.

I think people forget just how difficult it is to get any major infrastructure completed in this country now. It’s only going to get worse. Bureaucracy doesn’t vote for its own demise it takes a revolution and we are some way from dealing effectively with the blob.

The only big schemes Mayor Steve is backing that might come off are NPR to Manc Airport, and to Manc Piccadilly.
Pity he can’t do anything for the city region he represents, why do we need Lpool to Manc Airport anyway when scores of trains must currently go there everyday from all over the North, if ever there was a pure vanity project this is it, and Steve backs it to the hilt.

The general tone of cynicism in most of the comments is understandable. After a decade in power, most people now realising that the CA is more of a PR machine than actual delivery body.

Latest news concerning LCR is the Baltic railway station significantly delayed.
Everything this Mayor is involved in does not proceed, time for change.

The Mersey Estuary is the 10th best place in the UK for birds and the best place for Dunlin and Shelduck. A tidal barrage will have a damaging effect on these birds.
By Dermot Smith
It theory, the tidal barrage seems like a great, reliable, generator of green energy.I’m just curious on it’s barraging/ damming effects during a tidal surge? Where will surge wave energy be dispersed? Seems like this could benefit Liverpool, but how will this affect Sefton’s highly flood vulnerable coastal towns and wildlife habitats?
By Anonymous
With how energy expending, co2 emiting/polluting, a concreate structure of that magnitude would be to build, you’d think this tidal barrage system would be guaranteed useful for well over 120 years.
