SIGNIFICANT issues with a part of Pembroke’s tidal barrage are not expected to be fully fixed before late January, councillors heard.

Pembroke councillors Aaron Carey and Jonathan Grimes submitted an urgent question heard at the December meeting of Pembrokeshire County Council, which said: “In light of the repeated flooding events across the county – including the recent overflow at Castle Pond and the acknowledgement by your own Coastal, Rivers & Drainage Team that the barrage tipping gate remains inoperable until mid-January can you explain what assessment has been made of the adequacy of our tidal outfall infrastructure in the face of current and projected future storm surges and sea-level rise?

“If no such assessment has yet been undertaken, will you commit now to commissioning an immediate structural and risk-capacity audit, with a report to full council within three months, and with proposals for funding any remedial works required — to avoid recurring damage and disruption to residents, highways, and public amenities?”

Responding to the urgent question, Cabinet Member for Residents Services Cllr Rhys Sinnett said a significant assessment of the Pembroke Tidal Barrage had already been undertaken over the past two years, with regular inspections.

He said “a comprehensive package of works” began in September which were due to be completed before Christmas but said there had been “significant issues” with the tipping gate hydraulic ram, with a significant overhaul now taking place, with reinstatement expected by late January.

He told members additional mitigation measures were now in place and, once works are completed, enhanced works will provide improved resilience and “long-term reliability,” with further reports due to come to Cabinet.

Cllr Carey and Cllr Grimes had also submitted a notice of motion saying: “That this council notes with concern the repeated and increasingly severe flooding experienced in our coastal, estuarial and river-fringe communities over recent weeks — in particular the flooding events affecting the Commons/Castle Pond area.

“That the council further notes that, according to correspondence from the Coastal, Rivers & Drainage Team Manager, the tipping gate at the barrage remains out of operation until mid-January due to mechanical issues; meanwhile high tide, heavy rain, wind-driven tidal surges and overspill at the sluice have combined to overwhelm the drainage/outfall infrastructure.

“That we recognise the current maintenance schedule (delayed ‘til after the summer season) and the justification given — but further that such planning failed to foresee the likelihood of severe winter storm and surge events, which climate change makes more frequent and more intense.

“That this council therefore calls on the Cabinet to commission an urgent review of:

The adequacy of the current drainage/outfall and tidal-sluice infrastructure (barrage tipping gate, sluice/sluice-valve, flap valve, outfall capacity) for current and projected climate/tide conditions.
The maintenance scheduling policy for coastal and estuarial flood-risk assets, with a view to ensuring critical maintenance is completed before winter high-tide / storm-surge season, rather than — as at present — being delayed until after summer for ‘recreational / biodiversity’ reasons.

“That, pending the outcome of the review, the council should allocate appropriate emergency capital funding to remediate the barrages / sluices / outfalls at risk of failure or blockage — to safeguard residents, properties, highways and public amenities from further flooding.

“That, further, this council resolves to publish a public flood-resilience plan for the county, identifying all coastal and river-fringe ‘hotspots,’ maintenance schedules, responsible teams, and a transparent timeline for upgrades or remedial works — so residents have clarity and confidence in flood prevention measures.”

The notice of motion itself will be considered by the council’s Cabinet at a later date.

A MAJOR construction materials company has signed a long-term deal to use renewable energy from Welsh windfarms as part of efforts to cut carbon emissions.

Energy firm RWE has agreed a 15-year contract to supply electricity to Breedon Group plc, which operates sites across Great Britain producing materials including concrete, asphalt and cement.

Under the agreement, RWE will provide around 70 gigawatt hours of renewable electricity each year from its windfarm portfolio.

The power will initially come from the Gwynt y Môr offshore windfarm, about 24km off the coast of North Wales in the Irish Sea. From 2033, supply will switch to the Brechfa Forest West onshore windfarm in Wales.

The electricity will support the production of key building materials, helping Breedon reduce emissions linked to its energy use in a sector widely regarded as difficult to decarbonise.

RWE said the agreement highlighted the role renewable energy can play in helping heavy industry move towards lower-carbon operations.

Olaf Lubenow, head of commodity solutions at RWE, said: “This agreement underlines our commitment to supporting the construction materials sector on its journey towards a more sustainable future.

“By supplying renewable electricity from our wind portfolio, we are helping to reduce the carbon footprint of Breedon’s operations.”

Breedon said the deal would also provide long-term energy stability while supporting its wider sustainability plans.

Donna Hunt, the company’s sustainability director, said the agreement marked “a meaningful step forward”.

She said: “It secures long-term energy supply and helps accelerate the reduction of emissions from our operations.”

The company has set targets to cut emissions across its business by more than 20% by 2030 and to reach net zero by 2050.

The agreement reflects a growing trend of major industrial firms turning to renewable energy to help meet climate targets while managing rising energy costs.

Pembroke Power Station National Grid shutdown power plans

A CALL to site specialist diesel generators at Pembroke Power Station to help keep the lights on in the event of a National Grid shutdown has been lodged with county planners.

In a screening application to Pembrokeshire County Council, RWE Generation UK PLC, through Ove Arup & Partners Ltd, wants to site up to six containerised diesel generators, diesel storage tank(s) and electrical connections at Pembroke Power Station, Pwllcrochan, near Pembroke.

The application site is within the site of the existing Pembroke Power Station, a combined-cycle gas turbine (CCGT) station which began commercial operation in September 2012, with a gross consented capacity of about 2,199 megawatts electric (MWe), replacing the previous oil-fired power station which operated for almost 30 years and was decommissioned in 1999.

A supporting statement says, subject to confirmation, it is considered to comprise permitted development, the scheme “a standalone plant, with its own fuel supply, capable of starting up, operating and shutting down independently from the power station”.

It adds: “It is required only in an emergency to maintain plant status and keep the power station operationally ‘ready’ in the event of a total or partial shutdown of the National Grid system. It is not required for the normal operation of the power station and does not extend its capacity, which remains as already consented, therefore it is not considered a change or extension.”

On need, it says it is mandatory that all electricity generators of over a megawatt have to adopt a new minimum standard of asset resilience; power stations “must be capable of restoring demand on the National Grid electricity transmission system in the event of a total or partial shutdown of the National Grid system”.

“The Power Station does not currently meet this new asset resilience standard, therefore new back-up power, control philosophy and on-site services that support site critical systems enabling the power station to remain ready to operate must be implemented.

“RWE is required to install a new enhanced emergency site auxiliary solution (diesel generators and diesel storage tanks) at the power station for resilience against the failure of the interconnected electricity distribution network into which it is normally connected in order to satisfy the Grid Code requirements by the mandated implementation deadline of December 31, 2026.

“RWE will make operational and fuelling provision, within its new resilience design at Pembroke power station of up to 120 hours, in order to provide capability to a slightly enhanced standard known to be valued by the National Energy System Operator (‘NESO’) in certain emergency network scenarios.”

It says construction is hoped to start in July 2026, lasting approximately nine to 12 months, the main part across the summer months.

The call will be considered by county planners at a later date.

PLANS for a green energy scheme at a Pembrokeshire former country house which is now holiday apartments have been given the go-ahead.

In an application to Pembrokeshire Coast National Park, HPB Ltd, through agent Acanthus Holden Architects, sought permission for a biomass boiler plant and installation of 16 rows of solar panels to the south of the tennis courts, St Brides Castle, St Brides, along with the removal of two tennis courts, two polytunnels, two sheds and relocation of a container.

Marloes and St Brides Community Council: Supporting

An officer report recommending approval said: “St Brides Castle. Listed Grade II* is a former country house (now holiday apartments) just south-west of the small settlement of St Brides.

“The house and its listed ancillary buildings stand prominently within a large grade-II-registered park and garden. The development site lies immediately south of the registered asset, outside of its boundary.”

It added: “Although in a sensitive location, the proposed scheme is well-screened, utilising an existing hedged enclosure. The proposed panels do not protrude over the hedge line, the proposed extra planting to the south and west providing further screening. The proposed building, also well-screened, is of traditional design, proportions and materials.”

The application was conditionally approved by park planners.
