Massive investment needed in electricity grid to hit net zero, says expert report
Pembrokeshire will play vital role in UK’s green energy future
A NEW report from the Institution of Engineering and Technology (IET) has warned that the UK’s electricity transmission network must undergo its biggest upgrade since the 1960s if the country is to meet its legally binding net zero targets.
The independent study, released on Tuesday (Apr 29), outlines the huge financial, engineering and environmental considerations involved in expanding the high-voltage grid – and has implications for areas like Pembrokeshire, where wind and marine energy potential is among the highest in the UK.
The IET says a “massive increase” in grid capacity is essential to tap into Britain’s renewable energy resources – especially offshore wind – and deliver clean electricity to homes and businesses across the country.

The report compares the costs of overhead lines, underground cables, and subsea systems, showing that undergrounding is around 4.5 times more expensive than using pylons, while building a network of offshore high-voltage cables could be up to 11 times more expensive.
Despite the high costs, the report urges planners and policymakers to consider all factors – including visual impact, engineering feasibility, and environmental disruption – when selecting technologies for each location.
Local relevance
With projects like the proposed floating wind farms off the West Wales coast and grid reinforcements already underway in Pembrokeshire, the report’s findings are directly relevant to the region.
Much of the power generated by offshore wind farms in the Celtic Sea will need to be transmitted across long distances – requiring new infrastructure across rural parts of West Wales.
The Herald understands that National Grid is actively exploring routes for new transmission corridors in the area, and campaigners have already raised concerns about the visual impact of pylons on the Pembrokeshire landscape.
Expert views
Professor Keith Bell, Chair of the IET report’s Project Board, said: “Access to a cleaner, more secure supply of electricity will only be possible if we invest in transmission. This is the largest programme of network development in more than half a century.”
Professor Andrew Lovett, one of the report’s authors, added: “There are no easy answers. Whether it’s pylons across farmland, cables under the ground or subsea options off the coast, each approach comes with trade-offs that need to be carefully considered in context.”
David Reid from engineering firm Mott MacDonald, which led the research, said: “The grid must expand and evolve to meet the demands of net zero. This report helps clarify the real costs and benefits of each option.”
Impacts in Pembrokeshire
Energy developments in Pembrokeshire – including potential connections at Pembroke Dock, the Valero refinery, and Milford Haven port – will be critical to the UK’s energy transition.
The Herald has previously reported on concerns raised by residents and local councils about how new pylons and substations might affect views, wildlife, and tourism. The IET’s report calls for transparency and open discussions with communities before decisions are made.
The full report, Electricity Transmission Technologies Report, is available from the IET’s website.

Could Primark be coming to Haverfordwest? Major retailer in talks for former Wilko site
Council confirms advanced discussions as speculation grows over high street boost
HAVERFORDWEST could soon see a major high street revival, with a national retailer in advanced talks to take over the former Wilko building in the town centre.

Pembrokeshire County Council has confirmed that negotiations are ongoing, with a deal potentially just weeks — or even days — away.
Speaking to The Herald, Deputy Leader Cllr Paul Miller said the authority is in “detailed discussions with a major national retailer” over the prominent vacant unit.
However, he declined to name the business involved, citing commercial confidentiality.
Speculation grows
Despite the secrecy, speculation has been mounting locally that clothing giant Primark could be the retailer preparing to move into the site.
The size of the former Wilko store — one of the largest retail units in the town — has led many to believe only a handful of national chains would be able to occupy the space.
When asked directly whether Primark was involved, Cllr Miller did not confirm the claim, but also did not deny it.

Work already underway
The council has taken steps to prepare the building for a new tenant following Wilko’s collapse into administration.
This includes carrying out essential structural repairs, particularly to the roof, funded through a combination of council investment and an interest-free Welsh Government town centre loan.
Cllr Miller said the aim is to deliver a “blank canvas” for a new retailer, who would then invest further in fitting out the store.
He added that any incoming tenant would likely spend “millions” preparing the unit before opening.
Boost for town centre
The arrival of a major national retailer would represent a significant boost for Haverfordwest, which has faced challenges in recent years with declining footfall and the loss of several well-known stores.
The Wilko closure left a large gap in the town centre, both physically and economically, and securing a new anchor tenant is seen as key to revitalising the high street.
If confirmed, the move could increase visitor numbers, support surrounding businesses, and help restore confidence in the town’s retail future.

Deal ‘close’
Cllr Miller indicated that negotiations are at an advanced stage.
He said: “I’d like to think we’re talking weeks, not months — maybe even days, but these things can change.”
While no formal agreement has yet been announced, the timeline suggests a decision could be imminent.
What happens next
Until a deal is formally signed, the identity of the retailer remains unconfirmed.
However, with negotiations progressing and work underway on the building, expectations are growing that a major announcement could soon follow.
For now, all eyes remain on Haverfordwest — and on whether one of the UK’s biggest retail names is about to arrive.
We have contacted Primark for a comment.

Rail investment ‘could unlock 40,000 jobs and £11bn for Wales’ says new report
RAILWAY stations across Wales could help unlock around 40,000 jobs and more than £11 billion for the economy by 2036, according to new research.
A report by Development Economics, published on Monday (Mar 23), highlights how rail infrastructure is acting as a major driver of growth, supporting housing, business development, and employment across the country.
The findings suggest that development within 800 metres of railway stations alone could generate more than 40,000 jobs and contribute £11.3 billion to the Welsh economy over the next decade.

Stations driving growth
The report identifies what it calls the “rail catalyst effect”, where stations attract investment and act as hubs for regeneration.
Recent examples across Wales and the South West show the impact of rail-linked development. Over the past five years, areas around nine stations, including Carmarthen, have delivered 3,500 new homes, 67,000 square metres of commercial space, and supported 4,500 jobs.
Proposed new stations, including Cardiff Parkway and Newport West, are expected to create around 900 permanent jobs and generate £64 million annually over the next ten years.
Economic case for investment
The report comes as Wales continues to face economic challenges, with inactivity rates standing at 25.6%, higher than the UK average of 21.6%.
Researchers say continued investment in rail infrastructure will be key to boosting regional economies and improving access to jobs and opportunities.
Mark Hopwood, Managing Director of Great Western Railway, said: “The findings of this report are clear. The railway, its stations, and the trains that serve them are powerful drivers of economic growth, community prosperity and regeneration.
“Across our network, development around the railway is delivering thousands of homes, new commercial space and thousands of jobs, generating hundreds of millions of pounds in economic value for the communities we serve.”
National impact
Across the wider Great Western Railway network, stations are projected to support 238,000 jobs and generate £14.25 billion in annual economic value by 2036.
Nationally, the report suggests railway stations could support more than one million permanent jobs and contribute £78.7 billion to local and regional economies.
Wider benefits
The report also highlights the social impact of rail, particularly for households without access to a car, estimated at around one in five in Wales.
With more than 1.6 billion passenger journeys made each year across the UK rail network, the study says improved connectivity is helping people access work, education, and services more easily.

205-unit storage site at Pembrokeshire farm submitted to planners
A CALL to allow a Pembrokeshire farm to keep a storage facility for more than 200 caravans, boats, cars and farm machines as a form of diversification has been submitted to county planners.
In an application to Pembrokeshire County Council, Mr & Mrs Davies, through agent A.D Architectural Design Consultants Ltd, seek retrospective permission for a farm diversification scheme to accommodate the storage of caravans, boats, cars and farm machinery in four of eight agricultural sheds and on hard-standing concrete courtyards at Froghall Farm, Spittal.
The works were completed back in 2019.
A supporting statement accompanying the application said: “At present, four of the eight shed structures on the site form part of the caravan and boat storage scheme, with additional touring caravans stored externally on the concrete courtyards.”
It said the storage provision was split as follows: Shed 1 – farm workshop, and 30 caravans, motorhomes, boats & cars; shed 2 – 16 caravans; shed 3 – 28 caravans, motorhomes, boats & cars – 28; shed 8 – cubicle shed, 11 units of farm machines, motorhomes & caravans; courtyard storage of 120 touring caravans, for an overall storage of 205 units.
The statement added: “It would take place in an accessible location, would incorporate sustainable transport and accessibility principles and would not result in a detrimental impact on highway safety or in traffic exceeding the capacity of the highway network; access road is a no-through road with no increase in traffic due to the nature of development.
“There won’t be a constant stream/flow of traffic as the site’s used for storage. Our client offers a towing service to sites in and around Pembrokeshire, which is used by 45 per cent of their customers, who are unable or prefer not to tow themselves. This gives our client control over the flow of traffic.”
The application will be considered by county planners at a later date.
