Record year for Welsh heat pumps and solar panels
RECORD numbers of solar panels and heat pumps were installed in Welsh homes and businesses last year.
2023 saw more than double the amount of certified renewable installations in Wales than the previous year, bringing the total number of Welsh homes and businesses with renewable energy to over 100,000. 2023 was also the first year that installations rose above 20,000 in a single year, according to the MCS database of certified installations.
Solar panels made up the majority of the new renewable energy, with 14,730 MCS-certified installations across Wales. This represents a twelve-year high and is the highest level since Feed-In Tarriff grants were cut in 2011.
But the largest increase was in the heat pump sector, with a 147% increase in certified installations between 2022 and 2023. Experts at the MCS Foundation, which compiled the figures, said that Government grants introduced in 2022 have helped drive the rise in uptake. Households can now get £7,500 off the cost of a heat pump under the Boiler Upgrade Scheme, with applications for the grants rising rapidly.
Grants available for homeowners via the Welsh Government’s Nest scheme have also helped with the rollout of renewables. The Nest scheme is coming to an end, and is due to be replaced by a new scheme with a greater focus on low carbon technologies for the home.
Nearly one-in-ten households in Wales now have MCS-certified renewable installations, the highest proportion anywhere in the UK.
David Cowdrey, Director of External Affairs at the MCS Foundation, said: “The rapid rise of renewables in Wales is good news for people’s energy bills and for the climate.
“However, while the upward trend is encouraging, we need to be installing many more heat pumps, much faster, to meet climate change targets. Government policies like mandating heat pumps in all new-build homes and reducing the price of electricity so that heat pumps are guaranteed to be cheaper to run than a gas boiler will help to increase uptake.”
Nick Salini, Director of heat pump installer Thermal Earth, said “It is positive to see the increased uptake of renewables in Wales. Heat pumps are the future of home heating systems and viable in every type of building with correct design and installation.
“While this growth is welcome, we need significantly higher growth to get anywhere near the long term targets set by UK Government and reduce our national dependency on fossil fuels. In addition to installation financial support such as the BUS, we need lower electricity costs for heat pumps to further increase the running cost savings and more positive messaging of the advantages heat pumps offer homeowners to transition to away from traditional fossil fuel systems.”

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.
