UK wind power reaches historic 30GW milestone
The UK’s wind energy sector has achieved a significant milestone, reaching a total generation capacity of 30 gigawatts (GW). This landmark was attained following the opening of the Viking Wind Farm on the Shetland Islands, which added 443 megawatts (MW) to the country’s capacity.
The UK’s combined onshore and offshore wind capacity now stands at 30,299MW, according to RenewableUK’s EnergyPulse, the industry’s leading market intelligence service. This capacity is sufficient to meet the annual electricity needs of over 26 million homes and is expected to reduce carbon emissions by more than 35 million tonnes annually.
Wind power has been instrumental in the UK’s shift towards renewable energy, with wind energy accounting for a record 28.1% of the nation’s total electricity generation in 2023. In the same year, renewables provided 46.4% of the UK’s electricity, with wind power contributing over 60% of this total.
The journey to 30GW has been one of steady growth. The UK’s first commercial onshore wind farm in Delabole, Cornwall, began operations in 1991, followed by the first offshore project off Blyth, Northumberland, in 2000. It took until 2005 to reach 1GW of capacity, with growth accelerating in the subsequent years: 5GW was reached in 2010, 10GW in 2013, and 15GW in 2017. The latest milestone, 30GW, marks a doubling of capacity in just seven years.
The Viking Wind Farm, a project 15 years in the making and costing around £1.2 billion, is the largest onshore wind farm to be built in the UK in nearly a decade. With its 103 turbines, it will harness Shetland’s robust wind resources, delivering renewable energy via a 260km High Voltage Direct Current (HVDC) subsea cable. Viking is expected to become the UK’s most productive onshore wind farm, generating approximately 1.8 terawatt hours (TWh) of electricity annually, enough to power a city the size of Birmingham.
Commenting on the achievement, Ana Musat, RenewableUK’s Executive Director of Policy & Engagement, hailed the milestone as a testament to the industry’s rapid progress. “It took 26 years to install the first 15GW of wind energy in the UK, so to double that to 30GW in just seven years represents a tremendous success for the industry,” she said. Musat emphasised the importance of wind energy in the UK’s transition away from fossil fuels, highlighting research that suggests doubling the UK’s onshore wind capacity by 2030 could boost the economy by £45 billion and create 27,000 jobs.
Stephen Wheeler, Managing Director of SSE Renewables, expressed pride in the Viking Wind Farm’s contribution to the milestone. “As the largest onshore wind farm to be built in the UK in nearly ten years, the completion of the project is a big moment in its own right – and contributing to this milestone for the industry makes it even more special,” Wheeler remarked. He also noted the urgency of further expanding renewable energy to meet the UK’s zero-carbon targets by the end of the decade.
The achievement of 30GW is a significant step towards a cleaner energy future for the UK, but industry leaders warn that continued rapid expansion is essential to achieving the country’s long-term environmental and economic goals.
It is important to note: While the UK has reached an impressive 30GW of installed wind capacity, it’s important to note that actual electricity generation from wind power can vary due to the fluctuating nature of wind. On average, onshore wind farms operate at around 30% of their capacity, while offshore wind farms typically achieve around 40%. This means that at any given moment, the amount of electricity generated can be significantly lower than the total installed capacity. The development of efficient and affordable energy storage solutions will be crucial for maximising the potential of wind power in the UK’s energy mix.

Urgent calls for action on Pembroke Commons flooding
TWO PEMBROKESHIRE councillors have submitted an urgent call for action following recent heavy flooding in parts of Pembroke.
Pembroke councillors Aaron Carey and Jonathan Grimes have submitted an urgent notice of motion ahead of tomorrow’s December 12 meeting of Pembrokeshire County Council following heavy flooding in the town’s Commons and Castle Pond area.
The notice of motion covers six points.
“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 till 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 submission also includes a question for Cabinet Member Cllr Rhys Sinnett.
“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?”
A Pembrokeshire County Council spokesman has confirmed the 11th hour call will be heard by full council tomorrow.

UK marks 25 years since first offshore wind farm began generating power
Sector now powers millions of homes and supports 40,000 jobs
THE UK today (Dec 8) marks a significant milestone: 25 years since the country’s first offshore wind farm began generating electricity. Blyth Offshore Wind Farm, built off the Northumberland coast in 2000, consisted of just two turbines producing four megawatts of power — enough for three thousand homes — and laid the foundations for what has become one of the UK’s most important energy industries.
In the space of a single generation, offshore wind has grown into the UK’s largest source of clean electricity. In 2024 it provided more than thirty-four per cent of all renewable power and generated a record seventeen per cent of the UK’s electricity overall, totalling 48.5 terawatt hours. The current fleet has a combined capacity equivalent to five large nuclear power stations.
Across UK waters, 2,878 turbines are now in operation — ten floating and 2,868 fixed — with a total generating capacity of 16.1 gigawatts. That is enough to power more than sixteen million homes each year. Industry estimates suggest that, without this development, the UK would have had to burn an additional twenty million tonnes of gas over the past twenty-five years, producing more than sixty million tonnes of CO₂.
The sector’s growth has also reshaped the economy. Nearly two thousand companies now operate within the UK wind supply chain, including one hundred and sixty factories. Their combined activity is forecast to contribute £18.2bn to the UK economy over the next decade. Around forty thousand jobs are currently supported by offshore wind — a figure projected to rise to ninety-four thousand by 2030.
Construction is accelerating. More than 7.5GW of new offshore wind is already being built and is due to become fully operational within the next two years, with a further 22GW consented through to 2033.
‘Britain is once again leading the world in clean power’
Energy Minister Michael Shanks MP said: “Twenty-five years after the first offshore wind turbines began to turn, Britain is once again leading the world in clean homegrown power. Offshore wind is at the heart of our 2030 mission – helping us reduce our dependence on volatile fossil fuel markets, lower bills for good, and support one hundred thousand jobs by 2030.”
RenewableUK’s Deputy Chief Executive Jane Cooper said the sector’s progress had brought “jobs, investment, energy security, and environmental benefits in equal measure,” adding that next month’s clean power auction could secure a record amount of new offshore capacity. “A consistent pipeline of projects is vital to trigger new investment in factories and supply chain companies,” she said.
Julia Rose, Head of Offshore Wind at The Crown Estate, said the UK’s first 25 years demonstrated “the transformative power of collaboration and strategic vision,” noting that 45 operational wind farms are now in UK waters with a 95GW development pipeline. The Crown Estate plans to bring a further 20–30GW of new leasing opportunities to market by 2030.
Ed Daniels, CEO of Venterra Group, highlighted the role of the UK’s supply chain: “Offshore wind’s success has created tens of thousands of skilled jobs, rejuvenated coastal communities and established the UK as a global exporter of expertise. Continued investment is essential to deliver economic growth and energy security over the next twenty-five years.”

Fishguard ‘battery box’ scheme near school refused
PLANNERS have refused a Pembrokeshire ‘battery box’ electricity storage unit near a Pembrokeshire town school, which has seen local objections including fears of a potential risk to nearby school children.
In an application recommended for approval at the December meeting of Pembrokeshire County Council’s planning committee, AMP Clean Energy sought permission for a micro energy storage project on land at Fishguard Leisure Centre Car Park, near Ysgol Bro Gwaun.
The application had previously been recommended for approval at the November meeting, but a decision was deferred pending a site visit.
The scheme is one of a number of similar applications by AMP, either registered or approved under delegated planning powers by officers.
The battery boxes import electricity from the local electricity network when demand for electricity is low or when there are high levels of renewable energy available, exporting it back during periods of high demand to help address grid reliability issues; each giving the potential to power 200 homes for four hours.
The Fishguard scheme, which has seen objections from the town council and members of the public, was before committee at the request of the local member, Cllr Pat Davies.
Fishguard and Goodwick Town Council objected to the proposal on grounds including visual impact, and the location being near the school.
An officer report said the scheme would be well screened by a Paladin Fence, with a need to be sited close to an existing substation.
Speaking at the December meeting, Ben Wallace of AMP Clean Energy conceded the boxes were “not things of beauty” before addressing previously raised concerns of any potential fire risk, saying that “in the incredibly unlikely” event of a fire, the system would contain it for up to two hours, giving “plenty of time” for it to be extinguished, an alarm immediately sounding, with the fire service raising no concerns.
“These are fundamentally safe, the technology is not new,” he said, comparing them to such batteries in phones and laptops.
One of the three objectors at the meeting raised concerns of the proximity to homes and the school, describing it as “an unsafe, unsustainable and unnecessary location,” with Cllr Jim Morgan of Fishguard Town Council, who had previously raised concerns of the “nightmare scenario” of a fire as children were leaving the school, also voicing similar issues.
Local county councillor Pat Davies, who had spoken at the previous meeting stressing she was not against the technology, just the location and the potential risk to pupils, said the siting would be “a visual intrusion,” with the school having many concerns about the scheme, adding it had been “brought forward without any dialogue of consultation with the school”.
Cllr Davies added: “It is unacceptable that a micro-storage unit should be proposed in this area; someone somewhere has got it wrong.”
Following a lengthy debate, committee chair Cllr Mark Carter proposed going against officers in refusing the scheme; members unanimously refusing the application.
