Pembroke Power Station marks 10,000th turbine start
Milestone highlights growing importance of flexible gas generation as renewables expand
PEMBROKE POWER STATION has reached a major operational milestone after recording the 10,000th start of its combined cycle gas turbine (CCGT) units — underlining the plant’s continuing role in keeping the UK electricity system stable as renewable energy increases.
The RWE-owned power station, which opened in 2011, was originally designed to run almost continuously. However, as wind and solar generation have grown, the facility now operates far more flexibly, starting and stopping units to respond to changes in electricity demand and renewable output.
All five generating units now operate across multi-shift patterns, helping to balance the grid when renewable supply drops or when rapid increases in power are required.
Engineers at the site have also significantly improved performance over time. Start-up times have been reduced from around 70 minutes to just 41 minutes, allowing the station to respond more quickly to fluctuations in supply and demand. The units have also completed multiple major maintenance cycles while maintaining high reliability, including during the Covid-19 pandemic.
Gas-fired power remains a key part of Britain’s energy mix, providing what industry experts describe as “firm and flexible” generation capacity. While renewable sources are expected to supply the majority of electricity in the future, gas stations continue to provide backup and stability when renewable output is low or unpredictable.
Roland Long, RWE Pembroke Power Station Manager, said: “Reaching 10,000 unit starts is a proud moment for everyone at Pembroke. It highlights not just our operational capability but the vital contribution that flexible gas generation makes to the UK’s energy system.
“As the grid becomes increasingly driven by renewables, our ability to start quickly and run when needed ensures security of supply and reinforces Pembroke’s role as a dependable partner in the nation’s energy transition.”
The milestone reinforces the ongoing importance of flexible gas generation in supporting homes and businesses across the UK with secure and reliable electricity, particularly as the country continues to move towards lower-carbon energy sources.

Slebech Park wedding venue ran without planning permission for years
A CALL to keep a wedding venue, erected without permission at a Georgian Pembrokeshire hotel whose site once belonged to the Knights Hospitallers, has been given a five-year period of grace.
In a listed building application to Pembrokeshire Coast National Park, Traverse Development Ltd, through agent Harries Planning Design Management, sought retrospective permission for the temporary retention of a wedding marquee at Slebech Park Restaurant and Rooms, Slebech; works having started back in 2009.
Grade-II*-listed Slebech Park once belonged to the Knights Hospitallers of the order of St John, later becoming the seat of the powerful Barlow family.
The present house was completed in 1776, built by Anthony Keck. This is his largest known house and the biggest Georgian single build in the country.
The grade-II-listed stables, which have the marquee on their eastern terrace, were converted to a hotel, conference centre and restaurant after 2003.
A supporting statement accompanying the application said: “The proposal seeks to retain the already erected temporary marquee used for weddings to allow the site to continue to host weddings, whilst a permanent solution is developed and approved by planning.
“The marquee will continue to operate as it has for over 10 years, with no changes proposed. The marquee is completely removeable without any permanent fixtures.”
It added: “The marquee is only affixed temporarily and will be removed with no damage to any of the listed buildings or the overall site once a permanent solution has been agreed.
“By retaining the marquee in the same location, it ensures that continuation of the site is as existing, reduces the potential impact of moving the marquee to a potentially more harmful site and ensures any ecology is not further disrupted. Once removed the site will return to its historic state.”
An officer report recommending approval said no adverse comments have been received from consultees towards the current proposal, and no third-party representations raising issues relating to listed building matters have been received, the proposed scheme “in keeping with the character of the listed building, and its setting in terms of design and form”.
It added: “Temporary consent for this marquee has been granted on four previous occasions and a letter submitted in support of the current application states that an application for a permanent solution for a wedding venue at Slebech Park is imminent, in line with the original proposals for the terrace restaurant.
“The effect on character and setting is not considered acceptable long-term but short-term retention in the interests of retaining the complex of buildings in viable use (and repair) whilst a suitable permanent solution is found is considered reasonable. As such, the application can be supported for a temporary period subject to conditions.”
The application was approved, conditions including a five-year period of grace.

Celtic Freeport chief steps down less than two years after taking the job
THE HEAD of the Celtic Freeport has stepped down from the role less than two years after being appointed.
Luciana Ciubotariu officially left the post on April 16, with the organisation confirming her departure in a brief statement.
No explanation has been given for the move, but board members praised her contribution during a key period in the freeport’s development and said details of the search for a successor would be announced later.
Ms Ciubotariu joined the Celtic Freeport in May 2024 after previously working with Thames Freeport in London. She was brought in to help steer the project through its formative stages and played a central role in shaping its early direction.
Her exit comes at an important time for the scheme.
Only weeks ago, Neath Port Talbot Council approved a memorandum of understanding with the UK Government, Welsh Government, Pembrokeshire County Council and Celtic Freeport Company Limited. The agreement is intended to confirm the council’s role as the accountable body as the project moves into its next stage.
The Celtic Freeport, which was formally launched in late 2024, is a joint initiative involving Associated British Ports, the Port of Milford Haven, Pembrokeshire County Council and Neath Port Talbot Council.
The project is designed to create designated tax and customs zones aimed at attracting major investment and boosting economic growth across south-west Wales.
In a statement, the organisation said Ms Ciubotariu had led the freeport through the approval of its full business case and helped secure the memorandum of understanding with both the UK and Welsh governments.
That agreement is expected to unlock £25 million in public funding for the project.
The board said it was grateful for her work in helping establish the freeport and wished her well for the future.

Milford Haven dry dock pitched as home for giant £480m superyacht yard
Port says dock is being actively marketed as company unveils vast shed plan that could transform town skyline and create up to 3,000 jobs
A HUGE plan to turn Milford Haven’s dry dock into the heart of a £480 million superyacht construction and refit yard has been unveiled, in what could become one of the most dramatic development proposals ever put forward for the town.
Renderings released alongside the announcement show a colossal enclosed build hall covering the existing dry dock and dominating the waterfront skyline. Based on the images, the proposed structure appears likely to be nearly as long as some of the German submarine pens built on the French Atlantic coast during the war.

The scheme has been put forward by Superyacht Sales UK, which says it is in early-stage discussions with Milford Haven Port Authority over the possible use of the Port’s 180-metre dry dock as part of a long-term vision for a major new marine engineering hub in Pembrokeshire.
The company says the wider project could eventually support up to 3,000 skilled jobs and generate around £150 million a year in social value, while helping establish Milford Haven as a centre for superyacht refit, construction and green marine technology.

Port’s response cautious
Despite the eye-catching scale of the proposal, the Port has given only a limited response.

In a statement to The Herald, a spokesperson for Milford Haven Port Authority said: “The dry dock is commercially available for rent and is being actively marketed. We have responded to various organisations that have shown an interest. We are unable to comment further due to commercial sensitivities.”
That response makes clear the dry dock is being marketed commercially and that Superyacht Sales UK is not the only organisation to have shown interest.
The release issued by Superyacht Sales UK says the company is also exploring the possible development of a custom new-build shipyard on the site of the former Royal Naval Armaments Depot on the edge of Milford Haven. However, it acknowledges that no contact has yet been made with the current landowners and that the entire proposal remains at concept and feasibility stage.
Kerry Ballard, founder of Superyacht Sales UK, described the plans as a long-term ambition and said discussions with the Port were exploratory.
She said: “This is a long-term vision, and we are at a very early stage. Our discussions with Milford Haven Port Authority are exploratory, focused on understanding what may be possible in respect of the existing dry dock facilities.
“Milford Haven presents a compelling opportunity. The combination of deep-water access, industrial heritage, and alignment with the Celtic Freeport strategy, particularly around hydrogen and green energy, creates a highly attractive proposition for a next-generation shipyard.”
She added that any development of this scale would need to be shaped in partnership with the local community, stakeholders and education providers.
Questions over scale
There is no doubt the vision is bold. If built in anything like the form shown in the released images, the structure would completely alter the appearance of the docks and create a huge new industrial landmark visible across much of the town.
Rather than sitting beside the dry dock, the proposed shed appears designed to swallow it almost whole, enclosing the dock within a giant shell intended for superyacht construction and refit work under cover.
The sheer scale of the concept is likely to prompt both excitement and scepticism locally.
Supporters will point to Milford Haven’s deep-water access, industrial heritage, marine infrastructure and long association with heavy engineering and energy industries. In theory, those strengths could make it a credible location for specialist shipyard activity if sufficient private investment and commercial demand existed.
The company says the international market for superyachts over 30 metres is growing, with existing European yards facing capacity constraints. Its pitch is that West Wales could capture part of that market while also linking the development to future propulsion systems, including hybrid, battery-electric and hydrogen-powered vessels.
The proposal also includes talk of partnerships with colleges and universities to create training pathways in advanced composites, precision engineering and sustainable marine technologies.
Speculative at this stage
For Milford Haven, the attraction is obvious. A project on this scale would not just mean another industrial tenant taking over an existing dock facility. It would represent a major shift in ambition for the waterfront and could, if realised, bring a new type of high-value engineering work into Pembrokeshire.
But serious questions remain.
No planning application has been submitted. No formal development agreement has been announced. The Port has not indicated support for any specific proposal. At this stage, there is no public evidence of secured funding for a project on anything like the scale being discussed.
There are also likely to be wider questions about land control, infrastructure demands, environmental considerations, traffic, visual impact and whether local people would genuinely benefit from the promised jobs and training.
For now, the proposal remains an ambitious vision rather than a confirmed development.
If the idea progresses, it could mark the start the biggest waterfront development discussions the town has seen in years.
