A record-breaking amount of new offshore wind capacity has been secured at the UK’s latest auction for renewable energy projects.
Five fixed-foundation projects, amounting to 8.25 gigawatts (GW), secured fixed-price “contracts for difference” (CfDs) to supply electricity for an average of £91 per megawatt hour (MWh).
Additionally, two floating offshore wind projects with a combined capacity of 192.5 megawatts (MW) won contracts, securing a “strike price” of £216/MWh.
This new capacity, totalling 8.4GW, marks a significant increase from last year’s sixth auction, when 5.3GW had been secured as part of a bounce back from the “failed” fifth round.
While the latest auction saw offshore wind prices rising by around 10% since the previous round, analysis suggests that the outcome will, nevertheless, be roughly “cost neutral” for consumers.
Contrary to simplistic and misleading comparisons made by some opposition politicians and media commentators, this is because CfD payments would be balanced by lower wholesale costs.
The government welcomed the “stonking” results, saying that it put the country “on track” to reach its 2030 targets for clean power, create jobs and bring new investment.
Below, Carbon Brief looks at the auction results, what they mean for bills and the implications for the UK’s target of “clean power by 2030”.
- What happened in the seventh CfD auction round?
- What does the record offshore-wind auction mean for bills?
- What does AR7 mean for reaching clean power by 2030?
What happened in the seventh CfD auction round (AR7)?
The UK government announced the results of the seventh auction round (AR7) for new CfDs on 14 January 2026, hailing the outcome as a “historic win”.
The CfD scheme was introduced in 2014 and offers fixed-price contracts to generators via a “reverse auction” process. The first auction was held in 2015.
Projects bid to secure contracts to sell electricity at a fixed “strike price” in the future.
If wholesale prices are lower than this set amount, the project receives a payment that makes up the difference.
However, if the market prices are higher than this level, then the project pays back the difference to consumers. For example, according to a report from thinktank Onward, between November 2021 and January 2022, CfD projects paid back £114.4m to consumers.
For the seventh auction round, the results have been split into two, as part of reforms to help expedite the process for offshore wind. As such, the publication of results on 14 January covers fixed-foundation offshore wind and floating offshore wind.
A second set of results will be released between 6-9 February 2026, covering technologies including large-scale solar and onshore wind.
A total of 17 fixed-foundation offshore wind projects totalling 24.8GW of capacity were competing for contracts at this auction, meaning many have missed out.
Still, a record 8.4GW of offshore wind secured contracts, making it the biggest ever offshore wind auction in Europe, according to industry group WindEurope.
This includes 8,245 megawatts (MW) of fixed-foundation offshore wind and 192.5MW of floating offshore wind, which, collectively, will generate enough to power more than 12m homes.
As such, there was an increase of more than 3GW in offshore wind capacity compared to the sixth allocation round, as shown in the chart below.
(The 2.4GW Hornsea 4 scheme, which had been awarded a CfD at the previous auction round, went on to be cancelled in May 2025, with developer Ørsted citing cost inflation.)
This follows on from the “fiasco” of the fifth allocation round in 2023, where no offshore-wind projects secured contracts due to the limit on prices set by the government.
Carbon Brief analysis suggests that the capacity secured in the latest auction will generate around 37 terawatt hours (TWh) of electricity each year, around 12% of the nation’s total demand.
With onshore wind and solar results still to come, this means that projects with CfDs will generate some 135TWh of power by the time they are all completed, or nearly half of current demand.
When the current Labour government took office in 2024, a number of changes were made to encourage offshore wind capacity bids. This included separating the technology from solar and onshore wind into a separate “pot”, an allowance for “permitted reduction” projects in AR6 and a significant increase to the “budget” for the auction overall.
Since then, there have been continued reforms to help meet the government’s target of decarbonising power supplies by 2030. (See: What does AR7 mean for clean power by 2030.)
This includes extending the contracts from 15 years to 20 years, relaxing eligibility requirements related to planning consent and legislating to allow the secretary of state for energy – currently, Ed Miliband – to see anonymised bid information ahead of setting a final budget for that technology.
Initially, the government set a total budget of £900m for fixed-foundation offshore wind projects and £180m for floating offshore wind.
The budget for fixed-foundation offshore wind projects was then raised to £1,790m.
(Note that the “budget” is a notional limit on the amount of CfD levies that can be added to consumer electricity bills. This does not come from government coffers and – as explained below – it does not translate into an equivalent increase in consumer costs, because CfD projects also reduce wholesale electricity prices, which make up the bulk of bills.)
Ahead of the auction, the maximum “administrative” strike price was set at £113/MWh for offshore wind and £271/MWh for floating offshore wind.
The four winning fixed-foundation offshore wind projects in England and Wales secured a strike price of £91.20/MWh in 2024 prices and the one in Scotland £89.49/MWh, as shown in the table below. This comes out at a blended average of £90.91/MWh.
| Projects (fixed-foundation) | Capacity (MW) | Owners | Strike price (2024 prices) | Delivery year (phase one) |
|---|---|---|---|---|
| Awel y Mor | 775 | RWE, SWM, Siemens Financial Services | £91.20/MWh | 2030/31 |
| Dogger Bank South | 3,000 | RWE, Masdar | £91.20/MWh | 2030/2031 |
| Norfolk Vanguard East | 1,545 | RWE | £91.20/MWh | 2029/2030 |
| Norfolk Vanguard West | 1,545 | RWE | £91.20/MWh | 2028/2029 |
| Berwick Bank | 1,380 | SSE Renewables | £89.49/MWh | 2030/2031 |
The two floating offshore-wind projects will see a strike price of £216.46/MWh, shown below.
| Projects (floating) | Capacity | Owners | Strike price (2024 prices) | Delivery year (phase one) |
|---|---|---|---|---|
| Pentland | 92.5 | CIP, Eurus Energy, Hexicon | £216.46/MWh | 2029/2030 |
| Erebus | 100 | TotalEnergies, Simply Blue Energy | £216.46/MWh | 2029/2030 |
These prices are around 19% below the maximum level set ahead of the auction – a figure that had been cited by opposition politicians as “proof” that the round would be a “bad deal” for consumers.
Successful projects include RWE’s Awel Y Mor (775MW), the first Welsh project to win a CfD contract in more than a decade.
Dogger Bank South in Yorkshire and Norfolk Vanguard in East Anglia – which will be two of the largest offshore windfarms in the world – at 3GW and 3.1GW, respectively – both secured contracts.
Additionally, Berwick Bank in the North Sea became the first new Scottish project to win a CfD since 2022. At 4.1GW, the project being developed by SSE Renewables is the largest planned offshore-wind project in the world.
The projects are located around the UK, which is expected to ease grid connections. Nick Civetta, project leader at Aurora Energy Research, noted in a statement:
“83% of the capacity connects in areas of high power demand and greater network capacity, lowering the cost of managing the system.”
In terms of companies, German developer RWE has dominated the auction outcome, with 6.9GW of the capacity being developed overall.
What does the record offshore-wind auction mean for bills?
The auction results arrive at a moment of intense interest in energy bills, which remain significantly higher than before the global energy crisis in 2022.
The government, along with much of the energy industry, said the new offshore wind projects would lower bills, relative to the alternative of relying on more gas.
Meanwhile opposition politicians and right-leaning media used misleading figures to argue that gas power is cheap or that the new offshore wind projects would add large costs to bills.
Broadly speaking, there is some evidence to suggest that electricity bills will rise over the years to 2030 – largely as a result of investment in the grid – before starting to decline.
However, this is the case whether the UK pushes forward with its efforts to expand clean power or not – and is mainly dependent on the timing of electricity network investments and the price of gas.
At the same time, electricity demand is starting to rise as the economy electrifies – as shown in the figure below – and many of the UK’s existing power plants are nearing the end of their lives.
This means that new electricity generation will be needed, whether from offshore wind, gas-fired power stations or from other sources.
Adam Berman, director of policy and advocacy at industry group Energy UK, said ahead of the auction that renewables were the “cheapest” source of new supplies.
Similarly, Pranav Menon, senior associate at consultancy Aurora Energy Research, tells Carbon Brief that the key question is how to meet rising demand most cost-effectively. He says:
“Here, it is quite clear that the answer is renewables (up to a certain price and volume), given that new-build gas is much more expensive…(even after accounting for costs and intermittency for renewables).”
The government said that the price for offshore wind secured through AR7 was “40% lower than the cost of building and operating a new gas power plant”. It added:
“Britain has taken a monumental step towards ending the country’s reliance on volatile fossil fuels and lowering bills for good, by delivering a record-breaking offshore wind result in its latest renewables auction.”
In a similar vein, Dhara Vyas, head of Energy UK said in a statement that the results would “deliver lower bills”. She added:
“Today’s auction results will deliver critical national infrastructure that will strengthen our energy security and deliver lower bills, as well as provide jobs, investment and economic growth right across Great Britain.”
These statements rely on updated government estimates of the cost of different electricity-generating technologies, published alongside the auction results.
They also rely on two studies published by Aurora and another consultancy, Baringa, both commissioned by renewable energy firms involved in the auction.
The government’s new cost estimates reflect the inflationary pressures that have hit turbines for gas-fired generation, as well as offshore wind supply chains.
Carbon Brief analysis of the latest and previous figures suggests that the government thinks the cost of building a gas-fired power station has more than doubled. (Reports from the US point to even steeper three-fold increases in gas turbine costs.)
As such, building and operating new gas-fired power stations would be relatively expensive, at £147/MWh, according to the government. (This assumes the gas plant would only be operating during 30% of hours in each year, in line with the current UK fleet.)
While the offshore wind prices secured in AR7 are around 10% higher than in AR6, at £91/MWh, they would still be considerably lower than the cost of a new gas plant.
However, these figures for new gas and for offshore wind in AR7 do not reflect the wider system costs of keeping the electricity grid running at all times.
In late 2025, Baringa concluded that a strike price of up to £94.50/MWh for up to 8GW of offshore wind would be “cost neutral”. This does not include system balancing costs, which the study argues are relatively modest for each additional gigawatt of capacity.
Carbon Brief understands that, when taking this into account, the “cost neutral” price for further offshore capacity would be reduced by a few pounds. This implies that the AR7 result at £91/MWh is likely to be in or around the “cost-neutral” range, based on Baringa’s assumptions.
Also, in late 2025, Aurora concluded that new offshore wind could be secured at “no net cost to consumers”, provided that contracts were agreed at no more than £94/MWh.
In contrast to Baringa’s work, this study is based on what an Aurora press release describes as a “total system cost analysis”. This means it takes into account the cost of dealing with the variable output of offshore wind, such as system balancing and backup.
In an updated note following the results of the auction, Aurora said that it would “generate net consumer savings of just over £1bn up to 2035”. This is relative to a scenario where no offshore wind had been procured at the latest auction.
(In its pre-auction analysis, Aurora pointed to a reduction in consumer electricity bills of around £20 per household per year by 2035, relative to relying on more gas power instead.)
Writing on LinkedIn, Aurora data analyst Ivan Bogachev said that this was the case, even though it might appear to be “counterintuitive”. He added:
“Moreover, AR7 projects are primarily clustered in areas which see few network constraints, limiting any contribution to higher balancing costs.”
In contrast, Conservative shadow energy secretary Claire Coutinho and right-leaning media commentators cited misleading figures to claim that the auction was “locking us in” to high prices.
Coutinho has repeatedly cited a figure for the cost of fuel needed to run a gas-fired power station in summer 2025 – some £55/MWh – as if this is a fair reflection of the cost of electricity from gas.
However, this excludes the cost of carbon, which gas plants must pay under the UK emissions trading system and the “carbon price support”. It also ignores the cost of building new gas-fired capacity, which as noted above has soared in recent years.
Dr Callum McIver, a researcher at the UK Energy Research Centre (UKERC) and research fellow at the University of Strathclyde, tells Carbon Brief that “you can’t credibly strip out the cost of carbon” and that the £55/MWh figure is not an “apples-to-apples” comparison with the AR7 result.
McIver says that a fairer comparison would be with a new-build gas plant, which, according to the latest DESNZ cost of generation report, would come in at £147/MWh – and would remain at £104/MWh, even if the cost of carbon is ignored.
UKERC director Prof Robert Gross, at Imperial College London, tells Carbon Brief that Coutinho’s £55/MWh figure for gas is “unrealistically low” because it is below current wholesale prices, which averaged around £80/MWh in 2025.
Gross adds that, as well as ignoring carbon pricing, the figure is also for “existing and not new gas stations, which we will need and which will need to recover much increased CAPEX [capital cost]”.
Another factor often not taken into account by those criticising the price of renewable energy contracts is that these projects reduce wholesale prices, as noted in Aurora’s modelling.
Separate analysis published by the Energy and Climate Intelligence Unit (ECIU) thinktank finds that wholesale power prices would have been 46% higher in 2025 – at £121/MWh rather than £83/MWh – if there had been no windfarms generating electricity.
This is because windfarms push the most expensive gas plants off the system, reducing average wholesale prices. This is a well-known phenomenon known as the “merit order effect”.
What does AR7 mean for reaching clean power by 2030?
Offshore wind is expected to be the backbone of the UK’s electricity mix in 2030, making the stakes for this CfD auction particularly high.
Under the National Energy System Operator’s (NESO) independent advice to the government, half of electricity demand will be met by offshore wind by 2030. It says this requires between 43GW and 51GW of generating capacity from the technology.
This advice informed the government’s action plan for meeting 100% of electricity demand with clean power by the end of the decade, which also sets a target of 43-50GW of offshore wind.
Currently, the UK has around 17GW of installed offshore wind capacity, leaving a gap of 27-34GW to the government’s target range.
A further 10GW of capacity already had a CfD prior to the latest auction, excluding the cancelled Hornsea 4 project. The additional 8.4GW contracted in AR7 means the remaining gap to the minimum 43GW end of the government’s range is just 7GW, as shown below.
Speaking to journalists after the auction results were announced, Chris Stark, who is head of “Mission Control” for clean power 2030, told journalists that securing 8.4GW in AR7 put the UK on track for its targets. He added:
“The result today actually takes us now to within touching distance of the goals that we set for 2030 – more to come on that, as I mentioned, with the onshore technologies and the storage projects up and down this country.
“But this is, I think, a real endorsement for the steps that Ed Miliband has taken to bring about that goal of clean power by 2030, it will bring huge benefits to people here in the UK.”
There remain a number of challenges with the delivery of these offshore-wind projects – including securing a grid connection – that could threaten delivery before 2030.
Writing on LinkedIn, Bertalan Gyenes, consultant at LCP Delta, says that with a third of the new capacity set to deliver before 2030, a “swiftly delivered and ambitious [allocation round eight] would put DESNZ within touching distance of its targets”. However, he adds:
“The job is not over yet, the windfarms need to be connected, the network upgraded, consenting pipelines de-clogged – there can be no more delays and certainly no cancellations like what we had seen with Hornsea 4 after last year’s auction.”
McIver wrote on LinkedIn that the auction result “takes us into the goldilocks zone that just about keeps CP30 targets alive, if AR8 can similarly deliver”. He added:
“OK, looking at delivery years [for the contracted projects], maybe we’re aiming for roughly CP33 [clean power by 2033] now? Maybe that would be no bad thing.”
Within the briefing for journalists, Stark highlighted a number of steps undertaken by the government over the past 18 months to ease the challenges around the expansion of the renewable energy sector.
This includes removing “zombie projects” from the queue for connecting projects to the electricity network and announcing £28bn in investment for gas and electricity grids.
As such, the auction results fit within a “host of policies” designed to make the ambitious clean power by 2030 target possible, said Stark.
The second half of the CfD results, covering technologies such as onshore wind and solar, are expected out next month. DESNZ’s action plan set a range of 27-29GW and 45-47GW of capacity for the two technologies, respectively, if the country is to meet its 2030 clean-power target.

DeBriefed 6 February 2026: US secret climate panel ‘unlawful’ | China’s clean energy boon | Can humans reverse nature loss?
Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
Secrets and layoffs
UNLAWFUL PANEL: A federal judge ruled that the US energy department “violated the law when secretary Chris Wright handpicked five researchers who rejected the scientific consensus on climate change to work in secret on a sweeping government report on global warming”, reported the New York Times. The newspaper explained that a 1972 law “does not allow agencies to recruit or rely on secret groups for the purposes of policymaking”. A Carbon Brief factcheck found more than 100 false or misleading claims in the report.
DARKNESS DESCENDS: The Washington Post reportedly sent layoff notices to “at least 14” of its climate journalists, as part of a wider move from the newspaper’s billionaire owner, Jeff Bezos, to eliminate 300 jobs at the publication, claimed Climate Colored Goggles. After the layoffs, the newspaper will have five journalists left on its award-winning climate desk, according to the substack run by a former climate reporter at the Los Angeles Times. It comes after CBS News laid off most of its climate team in October, it added.
WIND UNBLOCKED: Elsewhere, a separate federal ruling said that a wind project off the coast of New York state can continue, which now means that “all five offshore wind projects halted by the Trump administration in December can resume construction”, said Reuters. Bloomberg added that “Ørsted said it has spent $7bn on the development, which is 45% complete”.
Around the world
- CHANGING TIDES: The EU is “mulling a new strategy” in climate diplomacy after struggling to gather support for “faster, more ambitious action to cut planet-heating emissions” at last year’s UN climate summit COP30, reported Reuters.
- FINANCE ‘CUT’: The UK government is planning to cut climate finance by more than a fifth, from £11.6bn over the past five years to £9bn in the next five, according to the Guardian.
- BIG PLANS: India’s 2026 budget included a new $2.2bn funding push for carbon capture technologies, reported Carbon Brief. The budget also outlined support for renewables and the mining and processing of critical minerals.
- MOROCCO FLOODS: More than 140,000 people have been evacuated in Morocco as “heavy rainfall and water releases from overfilled dams led to flooding”, reported the Associated Press.
- CASHFLOW: “Flawed” economic models used by governments and financial bodies “ignor[e] shocks from extreme weather and climate tipping points”, posing the risk of a “global financial crash”, according to a Carbon Tracker report covered by the Guardian.
- HEATING UP: The International Olympic Committee is discussing options to hold future winter games earlier in the year “because of the effects of warmer temperatures”, said the Associated Press.

Captured
Solar power, electric vehicles and other clean-energy technologies drove more than a third of the growth in China’s economy in 2025 – and more than 90% of the rise in investment, according to new analysis for Carbon Brief (shown in blue above). Clean-energy sectors contributed a record 15.4tn yuan ($2.1tn) in 2025, some 11.4% of China’s gross domestic product (GDP) – comparable to the economies of Brazil or Canada, the analysis said.
Spotlight
Can humans reverse nature decline?
This week, Carbon Brief travelled to a UN event in Manchester, UK to speak to biodiversity scientists about the chances of reversing nature loss.
Officials from more than 150 countries arrived in Manchester this week to approve a new UN report on how nature underpins economic prosperity.
The meeting comes just four years before nations are due to meet a global target to halt and reverse biodiversity loss, agreed in 2022 under the landmark “Kunming-Montreal Global Biodiversity Framework” (GBF).
At the sidelines of the meeting, Carbon Brief spoke to a range of scientists about humanity’s chances of meeting the 2030 goal. Their answers have been edited for length and clarity.
Dr David Obura, ecologist and chair of Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES)
We can’t halt and reverse the decline of every ecosystem. But we can try to “bend the curve” or halt and reverse the drivers of decline. That’s the economic drivers, the indirect drivers and the values shifts we need to have. What the GBF aspires to do, in terms of halting and reversing biodiversity loss, we can put in place the enabling drivers for that by 2030, but we won’t be able to do it fast enough at this point to halt [the loss] of all ecosystems.
Dr Luthando Dziba, executive secretary of IPBES
Countries are due to report on progress by the end of February this year on their national strategies to the Convention on Biological Diversity [CBD]. Once we get that, coupled with a process that is ongoing within the CBD, which is called the global stocktake, I think that’s going to give insights on progress as to whether this is possible to achieve by 2030…Are we on the right trajectory? I think we are and hopefully we will continue to move towards the final destination of having halted biodiversity loss, but also of living in harmony with nature.
Prof Laura Pereira, scientist at the Global Change Institute at Wits University, South Africa
At the global level, I think it’s very unlikely that we’re going to achieve the overall goal of halting biodiversity loss by 2030. That being said, I think we will make substantial inroads towards achieving our longer term targets. There is a lot of hope, but we’ve also got to be very aware that we have not necessarily seen the transformative changes that are going to be needed to really reverse the impacts on biodiversity.
Dr David Cooper, chair of the UK’s Joint Nature Conservation Committee and former executive secretary of the Convention on Biological Diversity
It’s important to look at the GBF as a whole…I think it is possible to achieve those targets, or at least most of them, and to make substantial progress towards them. It is possible, still, to take action to put nature on a path to recovery. We’ll have to increasingly look at the drivers.
Prof Andrew Gonzalez, McGill University professor and co-chair of an IPBES biodiversity monitoring assessment
I think for many of the 23 targets across the GBF, it’s going to be challenging to hit those by 2030. I think we’re looking at a process that’s starting now in earnest as countries [implement steps and measure progress]…You have to align efforts for conserving nature, the economics of protecting nature [and] the social dimensions of that, and who benefits, whose rights are preserved and protected.
Neville Ash, director of the UN Environment Programme World Conservation Monitoring Centre
The ambitions in the 2030 targets are very high, so it’s going to be a stretch for many governments to make the actions necessary to achieve those targets, but even if we make all the actions in the next four years, it doesn’t mean we halt and reverse biodiversity loss by 2030. It means we put the action in place to enable that to happen in the future…The important thing at this stage is the urgent action to address the loss of biodiversity, with the result of that finding its way through by the ambition of 2050 of living in harmony with nature.
Prof Pam McElwee, Rutgers University professor and co-chair of an IPBES “nexus assessment” report
If you look at all of the available evidence, it’s pretty clear that we’re going to keep experiencing biodiversity decline. I mean, it’s fairly similar to the 1.5C climate target. We are not going to meet that either. But that doesn’t mean that you slow down the ambition…even though you recognise that we probably won’t meet that specific timebound target, that’s all the more reason to continue to do what we’re doing and, in fact, accelerate action.

Key developments
Solar and wind eclipsed coal
‘FIRST TIME IN HISTORY’: China’s total power capacity reached 3,890 gigawatts (GW) in 2025, according to a National Energy Administration (NEA) data release covered by industry news outlet International Energy Net. Of this, it said, solar capacity rose 35% to 1,200GW and wind capacity was up 23% to 640GW, while thermal capacity – which is mostly coal – grew 6% to just over 1,500GW. This marks the “first time in history” that wind and solar capacity has outranked coal capacity in China’s power mix, reported the state-run newspaper China Daily. China’s grid-related energy storage capacity exceeded 213GW in 2025, said state news agency Xinhua. Meanwhile, clean-energy industries “drove more than 90%” of investment growth and more than half of GDP growth last year, said the Guardian in its coverage of new analysis for Carbon Brief. (See more in the spotlight below.)
DAWN FOR SOLAR: Solar power capacity alone may outpace coal in 2026, according to projections by the China Electricity Council (CEC), reported business news outlet 21st Century Business Herald. It added that non-fossil sources could account for 63% of the power mix this year, with coal falling to 31%. Separately, the China Renewable Energy Society said that annual wind-power additions could grow by between 600-980GW over the next five years, with annual additions of 120GW expected until 2028, said industry news outlet China Energy Net. China Energy Net also published the full CEC report.
STATE MEDIA VOICE: Xinhua published several energy- and climate-related articles in a series on the 15th five-year plan. One said that becoming a low-carbon energy “powerhouse” will support decarbonisation efforts, strengthen industrial innovation and improve China’s “global competitive edge and standing”. Another stated that coal consumption is “expected” to peak around 2027, with continued “growth” in the power and chemicals sector, while oil has already peaked. A third noted that distributed energy systems better matched the “characteristics of renewable energy” than centralised ones, but warned against “blind” expansion and insufficient supporting infrastructure. Others in the series discussed biodiversity and environmental protection and recycling of clean-energy technology. Meanwhile, the communist party-affiliated People’s Daily said that oil will continue to play a “vital role” in China, even after demand peaks.
Starmer and Xi endorsed clean-energy cooperation
CLIMATE PARTNERSHIP: UK prime minister Keir Starmer and Chinese president Xi Jinping pledged in Beijing to deepen cooperation on “green energy”, reported finance news outlet Caixin. They also agreed to establish a “China-UK high-level climate and nature partnership”, said China Daily. Xi told Starmer that the two countries should “carry out joint research and industrial transformation” in new energy and low-carbon technologies, according to Xinhua. It also cited Xi as saying China “hopes” the UK will provide a “fair” business environment for Chinese companies.

OCTOPUS OVERSEAS: During the visit, UK power-trading company Octopus Energy and Chinese energy services firm PCG Power announced they would be starting a new joint venture in China, named Bitong Energy, reported industry news outlet PV Magazine. The move “marks a notable direct entry” of a foreign company into China’s “tightly regulated electricity market”, said Caixin.
PUSH AND PULL: UK policymakers also visited Chinese clean-energy technology manufacturer Envision in Shanghai, reported finance news outlet Yicai. It quoted UK business secretary Peter Kyle emphasising that partnering with companies “like Envision” on sustainability is a “really important part of our future”, particularly in terms of job creation in the UK. Trade minister Chris Bryant told Radio Scotland Breakfast that the government will decide on Chinese wind turbine manufacturer Mingyang’s plans for a Scotland factory “soon”. Researchers at the thinktank Oxford Institute for Energy Studies wrote in a guest post for Carbon Brief that greater Chinese competition in Europe’s wind market could “help spur competition in Europe”, if localisation rules and “other guardrails” are applied.

Clean energy drove China’s economic growth in 2025
New analysis for Carbon Brief finds that clean-energy sectors contributed the equivalent of $2.1tn to China’s economy last year, making it a key driver of growth. However, headwinds in 2026 could restrict growth going forward – especially for the solar sector.
Below is an excerpt from the article, which can be read in full on Carbon Brief’s website.
Solar power, electric vehicles (EVs) and other clean-energy technologies drove more than a third of the growth in China’s economy in 2025 – and more than 90% of the rise in investment.
Clean-energy sectors contributed a record 15.4tn yuan ($2.1tn) in 2025, some 11.4% of China’s gross domestic product (GDP)
Analysis shows that China’s clean-energy sectors nearly doubled in real value between 2022-25 and – if they were a country – would now be the 8th-largest economy in the world.
These investments in clean-energy manufacturing represent a large bet on the energy transition in China and overseas, creating an incentive for the government and enterprises to keep the boom going.
However, there is uncertainty about what will happen this year and beyond, particularly due to a new pricing system, worsening industrial “overcapacity” and trade tensions.
Outperforming the wider economy
China’s clean-energy economy continues to grow far more quickly than the wider economy, making an outsized contribution to annual growth.
Without these sectors, China’s GDP would have expanded by 3.5% in 2025 instead of the reported 5.0%, missing the target of “around 5%” growth by a wide margin.
Clean energy made a crucial contribution during a challenging year, when promoting economic growth was the foremost aim for policymakers.
In 2024, EVs and solar had been the largest growth drivers. In 2025, it was EVs and batteries, which delivered 44% of the economic impact and more than half of the growth of the clean-energy industries.
The next largest subsector was clean-power generation, transmission and storage, which made up 40% of the contribution to GDP and 30% of the growth in 2025.
Within the electricity sector, the largest drivers were growth in investment in wind and solar power generation capacity, along with growth in power output from solar and wind, followed by the exports of solar-power equipment and materials.
But investment in solar-panel supply chains, a major growth driver in 2022-23, continued to fall for the second year, as the government made efforts to rein in overcapacity and “irrational” price competition.
Headwinds for solar
Ongoing investment of hundreds of billions of dollars represents a gigantic bet on a continuing global energy transition.
However, developments next year and beyond are unclear, particularly for solar. A new pricing system for renewable power is creating uncertainty, while central government targets have been set far below current rates of clean-electricity additions.
Investment in solar-power generation and solar manufacturing declined in the second half of the year.
The reduction in the prices of clean-energy technology has been so dramatic that when the prices for GDP statistics are updated, the sectors’ contribution to real GDP – adjusted for inflation or, in this case deflation – will be revised down.
Nevertheless, the key economic role of the industry creates a strong motivation to keep the clean-energy boom going. A slowdown in the domestic market could also undermine efforts to stem overcapacity and inflame trade tensions by increasing pressure on exports to absorb supply.
Local governments and state-owned enterprises will also influence the outlook for the sector.
Provincial governments have a lot of leeway in implementing the new electricity markets and contracting systems for renewable power generation. The new five-year plans, to be published this year, will, therefore, be of major importance.

Solar power, electric vehicles (EVs) and other clean-energy technologies drove more than a third of the growth in China’s economy in 2025 – and more than 90% of the rise in investment.
Clean-energy sectors contributed a record 15.4tn yuan ($2.1tn) in 2025, some 11.4% of China’s gross domestic product (GDP) – comparable to the economies of Brazil or Canada.
The new analysis for Carbon Brief, based on official figures, industry data and analyst reports, shows that China’s clean-energy sectors nearly doubled in real value between 2022-25 and – if they were a country – would now be the 8th-largest economy in the world.
Other key findings from the analysis include:
- Without clean-energy sectors, China would have missed its target for GDP growth of “around 5%”, expanding by 3.5% in 2025 instead of the reported 5.0%.
- Clean-energy industries are expanding much more quickly than China’s economy overall, with their annual growth rate accelerating from 12% in 2024 to 18% in 2025.
- The “new three” of EVs, batteries and solar continue to dominate the economic contribution of clean energy in China, generating two-thirds of the value added and attracting more than half of all investment in the sectors.
- China’s investments in clean energy reached 7.2tn yuan ($1.0tn) in 2025, roughly four times the still sizable $260bn put into fossil-fuel extraction and coal power.
- Exports of clean-energy technologies grew rapidly in 2025, but China’s domestic market still far exceeds the export market in value for Chinese firms.
These investments in clean-energy manufacturing represent a large bet on the energy transition in China and overseas, creating an incentive for the government and enterprises to keep the boom going.
However, there is uncertainty about what will happen this year and beyond, particularly for solar power, where growth has slowed in response to a new pricing system and where central government targets have been set far below the recent rate of expansion.
An ongoing slowdown could turn the sectors into a drag on GDP, while worsening industrial “overcapacity” and exacerbating trade tensions.
Yet, even if central government targets in the next five-year plan are modest, those from local governments and state-owned enterprises could still drive significant growth in clean energy.
This article updates analysis previously reported for 2023 and 2024.
Clean-energy sectors outperform wider economy
China’s clean-energy economy continues to grow far more quickly than the wider economy. This means that it is making an outsize contribution to annual economic growth.
The figure below shows that clean-energy technologies drove more than a third of the growth in China’s economy overall in 2025 and more than 90% of the net rise in investment.
In 2022, China’s clean-energy economy was worth an estimated 8.4tn yuan ($1.2tn). By 2025, the sectors had nearly doubled in value to 15.4tn yuan ($2.1tn).
This is comparable to the entire output of Brazil or Canada and positions the Chinese clean-energy industry as the 8th-largest economy in the world. Its value is roughly half the size of the economy of India – the world’s fourth largest – or of the US state of California.
The outperformance of the clean-energy sectors means that they are also claiming a rising share of China’s economy overall, as shown in the figure below.
This share has risen from 7.3% of China’s GDP in 2022 to 11.4% in 2025.
Without clean-energy sectors, China’s GDP would have expanded by 3.5% in 2025 instead of the reported 5.0%, missing the target of “around 5%” growth by a wide margin.
Clean energy thus made a crucial contribution during a challenging year, when promoting economic growth was the foremost aim for policymakers.

EVs and batteries were the largest drivers of GDP growth
In 2024, EVs and solar had been the largest growth drivers. In 2025, it was EVs and batteries, which delivered 44% of the economic impact and more than half of the growth of the clean-energy industries. This was due to strong growth in both output and investment.
The contribution to nominal GDP growth – unadjusted for inflation – was even larger, as EV prices held up year-on-year while the economy as a whole suffered from deflation. Investment in battery manufacturing rebounded after a fall in 2024.
The major contribution of EVs and batteries is illustrated in the figure below, which shows both the overall size of the clean-energy economy and the sectors that added the most to the rise from year to year.
The next largest subsector was clean-power generation, transmission and storage, which made up 40% of the contribution to GDP and 30% of the growth in 2025.
Within the electricity sector, the largest drivers were growth in investment in wind and solar power generation capacity, along with growth in power output from solar and wind, followed by the exports of solar-power equipment and materials.
Investment in solar-panel supply chains, a major growth driver in 2022-23, continued to fall for the second year. This was in line with the government’s efforts to rein in overcapacity and “irrational” price competition in the sector.
Finally, rail transportation was responsible for 12% of the total economic output of the clean-energy sectors, but saw relatively muted growth year-on-year, with revenue up 3% and investment by 6%.
Note that the International Energy Agency (IEA) world energy investment report projected that China invested $627bn in clean energy in 2025, against $257bn in fossil fuels.
For the same sectors as the IEA report, this analysis puts the value of clean-energy investment in 2025 at a significantly more conservative $430bn. The higher figures in this analysis overall are therefore the result of wider sectoral coverage.
Electric vehicles and batteries
EVs and vehicle batteries were again the largest contributors to China’s clean-energy economy in 2025, making up an estimated 44% of value overall.
Of this total, the largest share of both total value and growth came from the production of battery EVs and plug-in hybrids, which expanded 29% year-on-year. This was followed by investment into EV manufacturing, which grew 18%, after slower growth rates in 2024.
Investment in battery manufacturing also rebounded after a drop in 2024, driven by new battery technology and strong demand from both domestic and international markets. Battery manufacturing investment grew by 35% year-on-year to 277bn yuan.
The share of electric vehicles (EVs) will have reached 12% of all vehicles on the road by the end of 2025, up from 9% a year earlier and less than 2% just five years ago.
The share of EVs in the sales of all new vehicles increased to 48%, from 41% in 2024, with passenger cars crossing the 50% threshold. In November, EV sales crossed the 60% mark in total sales and they continue to drive overall automotive sales growth, as shown below.
Electric trucks experienced a breakthrough as their market share rose from 8% in the first nine months of 2024 to 23% in the same period in 2025.
Policy support for EVs continues, for example, with a new policy aiming to nearly double charging infrastructure in the next three years.
Exports grew even faster than the domestic market, but the vast majority of EVs continue to be sold domestically. In 2025, China produced 16.6m EVs, rising 29% year-on-year. While exports accounted for only 21% or 3.4m EVs, they grew by 86% year-on-year. Top export destinations for Chinese EVs were western Europe, the Middle East and Latin America.
The value of batteries exported also grew rapidly by 41% year-on-year, becoming the third largest growth driver of the GDP. Battery exports largely went to western Europe, north America and south-east Asia.
In contrast with deflationary trends in the price of many clean-energy technologies, average EV prices have held up in 2025, with a slight increase in average price of new models, after discounts. This also means that the contribution of the EV industry to nominal GDP growth was even more significant, given that overall producer prices across the economy fell by 2.6%. Battery prices continued to drop.
Clean-power generation
The solar power sector generated 19% of the total value of the clean-energy industries in 2025, adding 2.9tn yuan ($41bn) to the national economy.
Within this, investment in new solar power plants, at 1.2tn yuan ($160bn), was the largest driver, followed by the value of solar technology exports and by the value of the power generated from solar. Investment in manufacturing continued to fall after the wave of capacity additions in 2023, reaching 0.5tn yuan ($72bn), down 23% year-on-year.
In 2025, China achieved another new record of wind and solar capacity additions. The country installed a total of 315GW solar and 119GW wind capacity, adding more solar and two times as much wind as the rest of the world combined.
Clean energy accounted for 90% of investment in power generation, with solar alone covering 50% of that. As a result, non-fossil power made up 42% of total power generation, up from 39% in 2024.
However, a new pricing policy for new solar and wind projects and modest targets for capacity growth have created uncertainty about whether the boom will continue.
Under the new policy, new clean-power generation has to compete on price against existing coal power in markets that place it at a disadvantage in some key ways.
At the same time, the electricity markets themselves are still being introduced and developed, creating investment uncertainty.
Investment in solar power generation increased year-on-year by 15%, but experienced a strong stop-and-go cycle. Developers rushed to finish projects ahead of the new pricing policy coming into force in June and then again towards the end of the year to finalise projects ahead of the end of the current 14th five-year plan.
Investment in the solar sector as a whole was stable year-on-year, with the decline in manufacturing capacity investment balanced by continued growth in power generation capacity additions. This helped shore up the utilisation of manufacturing plants, in line with the government’s aim to reduce “disorderly” price competition.
By late 2025, China’s solar manufacturing capacity reached an estimated 1,200GW per year, well ahead of the global capacity additions of around 650GW in 2025. Manufacturers can now produce far more solar panels than the global market can absorb, with fierce competition leading to historically low profitability.
China’s policymakers have sought to address the issue since mid-2024, warning against “involution”, passing regulations and convening a sector-wide meeting to put pressure on the industry. This is starting to yield results, with losses narrowing in the third quarter of 2025.
The volume of exports of solar panels and components reached a record high in 2025, growing 19% year-on-year. In particular, exports of cells and wafers increased rapidly by 94% and 52%, while panel exports grew only by 4%.
This reflects the growing diversification of solar-supply chains in the face of tariffs and with more countries around the world building out solar panel manufacturing capacity. The nominal value of exports fell 8%, however, due to a fall in average prices and a shift to exporting upstream intermediate products instead of finished panels.
Hydropower, wind and nuclear were responsible for 15% of the total value of the clean-energy sectors in 2025, adding some 2.2tn yuan ($310bn) to China’s GDP in 2025.
Nearly two-thirds of this (1.3tn yuan, $180bn) came from the value of power generation from hydropower, wind and nuclear, with investment in new power generation projects contributing the rest.
Power generation grew 33% from solar, 13% from wind, 3% from hydropower and 8% from nuclear.
Within power generation investment, solar remained the largest segment by value – as shown in the figure below – but wind-power generation projects were the largest contributor to growth, overtaking solar for the first time since 2020.
In particular, offshore wind power capacity investment rebounded as expected, doubling in 2025 after a sharp drop in 2024.
Investment in nuclear projects continued to grow but remains smaller in total terms, at 17bn yuan. Investment in conventional hydropower continued to decline by 7%.
Electricity storage and grids
Electricity transmission and storage were responsible for 6% of the total value of the clean-energy sectors in 2025, accounting for 1.0 tn yuan ($140bn).
The most valuable sub-segment was investment in power grids, growing 6% in 2025 and reaching $90bn. This was followed by investment in energy storage, including pumped hydropower, grid-connected battery storage and hydrogen production.
Investment in grid-connected batteries saw the largest year-on-year growth, increasing by 50%, while investments in electrolysers also grew by 30%. The transmission of clean power increased an estimated 13%, due to rapid growth in clean-power generation.
China’s total electricity storage capacity reached more than 213GW, with battery storage capacity crossing 145GW and pumped hydro storage at 69GW. Some 66GW of battery storage capacity was added in 2025, up 52% year-on-year and accounting for more than 40% of global capacity additions.
Notably, capacity additions accelerated in the second half of the year, with 43GW added, compared with the first half, which saw 23GW of new capacity.
The battery storage market initially slowed after the renewable power pricing policy, which banned storage mandates after May, but this was quickly replaced by a “market-driven boom”. Provincial electricity spot markets, time-of-day tariffs and increasing curtailment of solar power all improved the economics of adding storage.
By the end of 2025, China’s top five solar manufacturers had all entered the battery storage market, making a shift in industry strategy.
Investment in pumped hydropower continued to increase, with 15GW of new capacity permitted in the first half of 2025 alone and 3GW entering operation.
Railways
Rail transportation made up 12% of the GDP contribution of the clean-energy sectors, with revenue from passenger and goods rail transportation the largest source of value. Most growth came from investment in rail infrastructure, which increased 6% year-on-year
The electrification of transport is not limited to EVs, as rail passenger, freight and investment volumes saw continued growth. The total length of China’s high-speed railway network reached 50,000km in 2025, making up more than 70% of the global high-speed total.
Energy efficiency
Investment in energy efficiency rebounded strongly in 2025. Measured by the aggregate turnover of large energy service companies (ESCOs), the market expanded by 17% year-on-year, returning to growth rates last seen during 2016-2020.
Total industry turnover has also recovered to its previous peak in 2021, signalling a clear turnaround after three years of weakness.
Industry projections now anticipate annual turnover reaching 1tn yuan in annual turnover by 2030, a target that had previously been expected to be met by 2025.
China’s ESCO market has evolved into the world’s largest. Investment within China’s ESCO market remains heavily concentrated in the buildings sector, which accounts for around 50% of total activity. Industrial applications make up a further 21%, while energy supply, demand-side flexibility and energy storage together account for approximately 16%.
Implications of China’s clean-energy bet
Ongoing investment of hundreds of billions of dollars into clean-energy manufacturing represents a gigantic economic and financial bet on a continuing global energy transition.
In addition to the domestic investment covered in this article, Chinese firms are making major investments in overseas manufacturing.
The clean-energy industries have played a crucial role in meeting China’s economic targets during the five-year period ending this year, delivering an estimated 40%, 25% and 37% of all GDP growth in 2023, 2024 and 2025, respectively.
However, the developments next year and beyond are unclear, particularly for solar power generation, with the new pricing system for renewable power generation leading to a short-term slowdown and creating major uncertainty, while central government targets have been set far below current rates of clean-electricity additions.
Investment in solar-power generation and solar manufacturing declined in the second half of the year, while investment in generation clocked growth for the full year, showing the risk to the industries under the current power market set-ups that favour coal-fired power.
The reduction in the prices of clean-energy technology has been so dramatic that when the prices for GDP statistics are updated, the sectors’ contribution to real GDP – adjusted for inflation or, in this case deflation – will be revised down.
Nevertheless, the key economic role of the industry creates a strong motivation to keep the clean-energy boom going. A slowdown in the domestic market could also undermine efforts to stem overcapacity and inflame trade tensions by increasing pressure on exports to absorb supply.
A recent CREA survey of experts working on climate and energy issues in China found that the majority believe that economic and geopolitical challenges will make the “dual carbon” goals – and with that, clean-energy industries – only more important.
Local governments and state-owned enterprises will also influence the outlook for the sector. Their previous five-year plans played a key role in creating the gigantic wind and solar power “bases” that substantially exceeded the central government’s level of ambition.
Provincial governments also have a lot of leeway in implementing the new electricity markets and contracting systems for renewable power generation. The new five-year plans, to be published this year, will therefore be of major importance.
About the data
Reported investment expenditure and sales revenue has been used where available. When this is not available, estimates are based on physical volumes – gigawatts of capacity installed, number of vehicles sold – and unit costs or prices.
The contribution to real growth is tracked by adjusting for inflation using 2022-2023 prices.
All calculations and data sources are given in a worksheet.
Estimates include the contribution of clean-energy technologies to the demand for upstream inputs such as metals and chemicals.
This approach shows the contribution of the clean-energy sectors to driving economic activity, also outside the sectors themselves, and is appropriate for estimating how much lower economic growth would have been without growth in these sectors.
Double counting is avoided by only including non-overlapping points in value chains. For example, the value of EV production and investment in battery storage of electricity is included, but not the value of battery production for the domestic market, which is predominantly an input to these activities.
Similarly, the value of solar panels produced for the domestic market is not included, as it makes up a part of the value of solar power generating capacity installed in China. However, the value of solar panel and battery exports is included.
In 2025, there was a major divergence between two different measures of investment. The first, fixed asset investment, reportedly fell by 3.8%, the first drop in 35 years. In contrast, gross capital formation saw the slowest growth in that period but still inched up by 2%.
This analysis uses gross capital formation as the measure of investment, as it is the data point used for GDP accounting. However, the analysis is unable to account for changes in inventories, so the estimate of clean-energy investment is for fixed asset investment in the sectors.
The analysis does not explicitly account for the small and declining role of imports in producing clean-energy goods and services. This means that the results slightly overstate the contribution to GDP but understate the contribution to growth.
For example, one of the most important import dependencies that China has is for advanced computing chips for EVs. The value of the chips in a typical EV is $1,000 and China’s import dependency for these chips is 90%, which suggests that imported chips represent less than 3% of the value of EV production.
The estimates are likely to be conservative in some key respects. For example, Bloomberg New Energy Finance estimates “investment in the energy transition” in China in 2024 at $800bn. This estimate covers a nearly identical list of sectors to ours, but excludes manufacturing – the comparable number from our data is $600bn.
China’s National Bureau of Statistics says that the total value generated by automobile production and sales in 2023 was 11tn yuan. The estimate in this analysis for the value of EV sales in 2023 is 2.3tn yuan, or 20% of the total value of the industry, when EVs already made up 31% of vehicle production and the average selling prices for EVs was slightly higher than for internal combustion engine vehicles.
