Wales eyes £47 billion in renewable energy investment by 2035
WALES is on the cusp of a £47 billion renewable energy investment wave that could transform its economy, create thousands of jobs, and breathe new life into communities. This promising outlook was unveiled today at the Future Energy Wales 2024 conference at Newport’s ICC, showcasing preliminary analysis by BiGGAR Economics on the economic potential of renewable energy across the nation.
Commissioned by RenewableUK Cymru, in partnership with Solar Energy UK and Marine Energy Wales, the study highlights the substantial economic gains Wales could achieve by meeting its renewable energy targets across onshore wind, offshore wind, solar, and tidal power.

The research projects an average annual investment of nearly £4 billion, reaching a peak of £7 billion by 2028. Offshore wind alone is expected to attract £32.4 billion, forming the foundation of Wales’ economic growth through 2035. However, capturing this opportunity requires an effective industrial strategy and substantial port infrastructure upgrades to support thousands of new, high-quality jobs.
While offshore wind presents long-term growth, onshore wind offers Wales a rapid boost, with a potential £4.5 billion in investments enabling an increase to over 3 GW capacity by 2035, contingent on addressing planning and grid capacity challenges.
The NESO 2030 Clean Power report underscores the need for grid reform to expedite renewable energy across the UK, but Wales remains hampered by immediate planning resource shortages.
The latest data from the 2024 Welsh wind power report shows a surge in renewable project interest, with Wales’ pipeline expanding by 18% this year, from 9 GW in 2023 to over 10.5 GW in November 2024, largely due to new onshore wind projects. However, with current deployment rates, Wales is forecast to contribute only 5% of the UK’s total wind capacity by 2035—well behind Scotland’s 64 GW target.
RenewableUK Cymru’s Call for Strategic Support
Jess Hooper, Director of RenewableUK Cymru, said:
“Wales stands at the threshold of a historic opportunity. By harnessing this renewable investment potential, we can secure Welsh jobs and build a robust, long-term local economy. But achieving this vision requires strong, immediate support from both the UK and Welsh governments.
“We urge a coordinated, four-nations approach to accelerate wind deployment and grid upgrades. With strategic investment in grid capacity and planning, wind energy can become central to Wales’ clean energy future—delivering real benefits for our climate, economy, and communities.”
£47 Billion Equals 208 Principality Stadiums
Nikki Keddie, Director at BiGGAR Economics, added:
“The scale of Wales’ renewables potential is extraordinary. The £47 billion needed to reach our targets is equivalent to building 208 Principality Stadiums. Investment in renewables will boost energy security, employment, industrial growth, and rural development.
“To maximise economic benefits, it’s crucial to dismantle barriers to project delivery and create opportunities for local businesses to capture value. We look forward to the next phase of this report, where we will detail the economic share Wales can secure.”

New deal aims to unlock Wales’ renewable energy potential
Sector partnership targets 100% renewable electricity by 2035
A NEW deal has been launched to help Wales meet its renewable energy targets while ensuring greater benefits for local communities.
The Renewable Energy Sector Deal will see the Welsh Government and industry work in strategic partnership to unlock the full economic potential of Wales’ renewable energy future.
The announcement coincides with the publication of the latest Energy Generation and Energy Use in Wales report, which shows renewable electricity generation in 2024 was equivalent to 54% of Wales’ electricity consumption.
The Welsh Government has set a target for renewable electricity to meet 70% of demand by 2030 and 100% by 2035. It also aims to deliver at least 1.5 gigawatts of locally owned renewable energy capacity by 2035.
The Sector Deal is intended to accelerate deployment across onshore and offshore wind, solar, marine and hydro projects. It will also focus on strengthening supply chains, developing skills, and ensuring communities across Wales benefit directly from renewable energy developments.
Cabinet Secretary for Economy, Energy and Planning, Rebecca Evans, is launching the deal during a visit to the Morlais tidal energy project on Anglesey.
The Morlais scheme, owned and managed by social enterprise Menter Môn, is set to become the largest consented tidal energy project in Europe. The Welsh Government holds an £8 million equity stake in the project.
Rebecca Evans said: “Our ambition is to become a world leader in renewable energy, creating jobs and green growth to make families in Wales more prosperous and help with the cost of living.
“The current conflict in the Middle East has further highlighted the importance of energy independence. Our Renewable Energy Sector Deal will provide a strong foundation for future delivery, benefiting our economy, environment and energy security.
“The Morlais project shows how sustained partnership can unlock Wales’ natural energy resources and turn them into lasting economic opportunities for local communities and businesses.
“The latest energy report shows we are making progress towards our targets. Combined with the record 20 major renewable projects, totalling 1,400MW, backed in the most recent UK Government Contracts for Difference auction, it is clear we are building a more resilient, renewable-powered future.”
Dafydd Gruffydd, Managing Director of Menter Môn, added: “The Renewable Energy Sector Deal is an important step in accelerating growth in Wales and across the UK.
“It recognises the role marine energy schemes like Morlais can play in strengthening energy security, creating high-quality jobs and delivering long-term economic benefits for communities such as Anglesey.”
The Sector Deal was co-produced by a task and finish group made up of developers and community organisations.
Responding to the Welsh Government’s Renewable Energy Sector Deal, Welsh Liberal Democrat Leader Jane Dodds MS said: “This so-called ‘sector deal’ raises more questions than it answers.
“There is no clear plan for how we build the workforce needed, with no detail on training, skills or apprenticeships to deliver the green jobs Wales needs.
“Ministers also promise benefits for communities, but without minimum standards or enforcement, there is no guarantee local people will see the rewards.
“Most concerning is the lack of focus on energy bills. Families are struggling, yet there is no clear explanation of how this will bring down costs. Renewable energy should mean cheaper bills, but as long as electricity prices are tied to gas, households won’t feel the benefit, something Labour in Westminster has failed to fix.”

Research vessel begins mission to study seabed carbon in Irish Sea
Bangor University scientists join £2.1m project investigating the impact of bottom trawling on carbon stored beneath the seabed
A STATE OF THE ART research vessel has set sail from Liverpool to investigate how bottom trawling may affect carbon stored in the seabed of the Irish Sea.
The scientific expedition is part of a £2.1 million research project funded by the Natural Environment Research Council and led by Professor Jan Geert Hiddink of Bangor University.
A team of eighteen scientists has embarked on the RRS Discovery, one of the world’s most advanced research vessels, for a three-and-a-half-week voyage studying the impact of fishing activity on carbon held in seabed sediments.
Before the ship departed, a number of local dignitaries were invited aboard for a tour of the vessel, including Liverpool City Region Mayor Steve Rotheram and National Oceanography Centre Operations Director Natalie Campbell.
Professor Jan Geert Hiddink, from Bangor University’s School of Ocean Sciences, said bottom-trawl fishing is both vital to global food supply and a major disturbance to seabed environments.
“Bottom-trawl fishing provides around a quarter of global seafood but is also the most extensive physical disturbance caused by human activities to stocks of carbon locked in seabed sediments,” he said.
“This is important because recent evidence suggests that disturbing the seabed could lead to the release of significant amounts of greenhouse gases from the seabed into the atmosphere.
“There are still major uncertainties about how this disturbance affects carbon stored beneath the seabed. As a result, the impact of these disturbances is largely unquantified and currently unregulated.
“The aim of this project is to gain a much clearer understanding of what is happening so that scientists, policymakers and regulators can make informed decisions in the future.”
Seven research organisations are collaborating on the project: Bangor University, the Centre for Environment, Fisheries and Aquaculture Science (CEFAS), Heriot-Watt University, the University of Leeds, Plymouth Marine Laboratory, the University of St Andrews, and Imperial College London.

Green hydrogen plant approved for Milford Haven Freeport site
Major investment expected to boost low-carbon industry and create skilled jobs in West Wales
A MAJOR green hydrogen project planned for the Milford Haven Freeport tax site has taken a significant step forward after developers approved the final investment decision.
Energy company MorGen Energy has confirmed it will proceed with the West Wales Hydrogen project, one of the first schemes backed through the UK Government’s Hydrogen Allocation Round (HAR1) to reach this stage.
The facility will be built within the Milford Haven Tax Site, part of the Celtic Freeport zone covering Pembrokeshire and Neath Port Talbot.
Construction is expected to begin in 2026, with the plant scheduled to become operational in early 2028.
Once completed, the site is expected to produce around 2,000 tonnes of low-carbon hydrogen each year, meeting the UK’s Low Carbon Hydrogen Standard.
The hydrogen produced will support a range of industries, including port operations, manufacturing and industrial heating, as well as use as a chemical feedstock.
Supporters say the development will help reduce carbon emissions while strengthening Milford Haven’s role in the UK’s emerging hydrogen economy.
The project is also expected to create skilled jobs and provide work for local contractors during the construction phase.
Further expansion may be possible in future phases as demand for hydrogen grows, potentially helping establish Milford Haven as a major hub for low-carbon energy production serving South Wales and beyond.
Luciana Ciubotariu, Chief Executive of Celtic Freeport, said the decision marked another milestone for the region.
She said: “MorGen Energy’s decision is another major step forward for the hydrogen economy in South West Wales.
“Projects like this within the Milford Haven Tax Site show how the Celtic Freeport is accelerating decarbonisation while creating high-value jobs.”
The UK Government’s Hydrogen Allocation Round scheme provides revenue support to help scale up the country’s low-carbon hydrogen sector and bring early projects to market.
