China has seen a series of temperature records broken this summer, as heatwaves have struck various regions across the country.
Between mid-March and mid-July 2025, it was hit by an unprecedented number of “hot days” – where temperatures reach or exceed 35C – according to the China Meteorological Administration (CMA) .
In both May and June, heatwaves swept across northern regions, with temperatures in Xinjiang reaching as high as 46.8C.
Such a record-breaking summer is becoming increasingly common, with the CMA’s annual Climate Bulletins showing that hundreds of local heat records have been surpassed over the past decade.
The CMA says that “extreme high temperatures” have shown an “increasing trend” in China since its records began in 1961.
Experts tell Carbon Brief that heatwaves strongly affect public health, agricultural output and economic activity.
They also put significant strain on the electricity system.
In this Q&A, Carbon Brief looks at how heat extremes are changing in China, the role of climate change in making these worse and how the country is adapting to the impacts.
How are heat extremes changing in China?
The latest science report from the Intergovernmental Panel on Climate Change (IPCC) states that it is “virtually certain” that “the frequency and intensity of hot extremes have increased” across the world since 1950.
The IPCC adds that it is “virtually certain” that human-caused greenhouse gas emissions are “the main driver”.
China is no exception. In a press release for its latest 2025 “blue book on climate change in China”, the CMA says China is “susceptible to the impacts of global climate change”, noting:
“[China’s] warming rate is higher than the global average…and extreme weather and climate events are becoming more frequent and intense.”
Data from the CMA’s Climate Bulletins show how the average annual temperature in China is rising and how 2024 was the hottest year on record, as shown in the chart below.
While 2024 was the hottest year on record overall, this was a result of consistently high temperatures throughout the seasons.
At a CMA press conference in 2025, Chan Xiao, deputy director of the CMA commented:
“Temperatures were consistently high throughout the year, with significant fluctuations in temperature during winter. Spring, summer and autumn temperatures were all record highs for the same period.”
In contrast, more heat records were broken during 2022, even though it was not quite as hot overall. Explaining this, Prof Yang Chen from Chinese Academy of Meteorological Sciences, which falls under the CMA, tells Carbon Brief:
“[For] the annual mean air temperatures, every day counts. So even if the 2022 was exceptional for its large number – actually also very long duration-consecutive days and high-magnitude – of hot extremes, mainly during summer and in the Yangtze River Valley, it does not mean the remaining days were hotter than the counterparts in 2024.”
The CMA defines a “hot day” or “high temperature day” as one that reaches or exceeds 35C. It adds that “high temperatures for several consecutive days constitute a heatwave”.
As the global climate has warmed, the number of “hot days” that China is experiencing has been on the rise, shown in the figure below.
The year 2022 set a new record, with meteorological stations in China recording an average of 16.4 hot days. This was 7.3 more than the average for 1991-2020. The year 2024 came close to this record, with 15.6 hot days. These two years have also seen China’s hottest summers on record.
In 2022, more than 1,000 meteorological stations in China reported heatwaves, with 441 breaking “historical records”. For 2024, 74 stations reported “consecutive high temperature days” and 81 of them broke records.
Xiao said at a press conference in 2023 that “continuous high temperatures” in China’s central and eastern regions lasted for 79 days in the summer of 2022. The provinces of Gansu and Xinjiang in north-west China, Hubei in central China and Sichuan in south-west China all reported their “highest temperatures since 1961”.
In addition, the “maximum daily temperature [in the summer of 2022] at 361 national meteorological stations – accounting for 14.9% of the total number of stations in the country – reached or exceeded historical extremes”, Xiao added.
The CMA has also highlighted that summer is arriving earlier for much of China. In 2024, for example, summer in regions including most of Hainan province in south China, central Yunnan province in south-west China as well as central and southern Xinjiang province in north-west China arrived more than 20 days earlier than average.
“If a year’s spring and summer are longer, the potential heatwaves…will also be longer,” Prof Wenjia Cai, from the department of earth system science of Tsinghua University, tells Carbon Brief.
Cai notes that there are more ways to define heatwaves than CMA’s absolute threshold of 35C.
For example, a heatwave can also be defined by how long the hot weather persists, or based on “the daily maximum temperature, daily average temperature, or even nighttime temperature”, she tells Carbon Brief.
However, regardless of the definition used, the “number of heatwave days is definitely increasing as a result of climate change”, she adds.
What role does human-caused climate change play?
A field of climate science called “attribution” has emerged over the past two decades to establish the role that human-caused warming plays in individual extreme weather events, including heatwaves, floods, droughts and storms.
Attribution studies can also be used to find the “fingerprint” of human-caused climate change in longer-term trends, such as the gradual increase in surface temperatures over multiple decades.
Heat is the most-studied extreme event in attribution literature, as it is mainly driven by thermodynamic influences – in other words, it is relatively easy to study.
In contrast, storms and droughts are more strongly affected by complex atmospheric dynamics and, as such, can be trickier to simulate in a model. Cai tells Carbon Brief:
“High temperature is the most obvious trend against the background of climate change. Heatwaves, in comparison to events such as rainfall and typhoons, are also more predictable.”
Carbon Brief has produced an interactive map showing every attribution study published up to November 2024. In total, 114 extremes and trends in China have been the subject of an attribution study, including more than 20 relating specifically to extreme heat.
One study included on the map looks at the change in the intensity and frequency of extreme temperatures across China over 1951-2018. The authors say that, over this time period, “more intense and more frequent warm extremes” were observed across “most regions” in China – and that “greenhouse gas forcing plays a dominant role” in this.
Looking at individual extreme events, one analysis by the “rapid attribution” group World Weather Attribution investigates the then-record-breaking heat across China in July 2023. The analysis says that temperatures exceeded 50C in north-west China, adding that Sanbao, in Xinjiang, hit 52.2C on 16 July of that year.
The study finds that, in a world without climate change, such an extreme heat event would have been “extremely rare” and would only have happened once every 250 years. However, in today’s climate, as a result of human-caused climate change, a heatwave of this intensity is now expected once every five years.
This means China’s extreme heat of July 2023 was 50 times more likely due to climate change. The study also finds that in a world without climate change, the heatwave over China would have been 1C cooler.
A separate study finds that human-caused climate change also caused a more than 60-fold increase in the likelihood of the extremely warm 2013 summer, compared to the early 1950s.
It adds that other factors such as urbanisation and changes in atmospheric circulation patterns can also make heat extremes more intense and frequent.
What impact are these heatwaves having?
Heatwaves have a wide variety of impacts on human activities, such as public health, crop yields and economic output.
Older people are particularly vulnerable to extreme heat. The 2024 report from the Lancet Countdown on Health and Climate Change found that, in 2023, demographic changes alone could have driven a 65% increase in heat-related deaths among over-65s, compared to the 1990-99 average.
Cai, who is also the lead author of the Lancet Countdown’s China report, tells Carbon Brief that older people are the “most commonly mentioned vulnerable group” and that the number of people affected by heatwaves will grow as societies age.
However, heatwaves also “affect outdoor activities” regardless of age group, she adds, as well as having impacts on sleep and allergies:
“We don’t want anyone to think they are in a group of people unaffected by heatwaves.”
Cai says that heat exposure can increase the incidence of certain dangerous behaviours, such as domestic violence, as well as a wide range of diseases – including cardiovascular diseases and respiratory diseases – and mental health disorders.
In 2023, more than 30,000 deaths were related to heatwaves in China – 1.9 times higher than the average over 1986-2005, according to Cai and her colleagues’ China report.
This was a result of increased heat exposure – the average number of “heatwave exposure days” per person reached 16 days in 2023, more than three times the historical average (1986-2005), the report adds.
A 2022 attribution study on China notes that extreme heat can also increase the risk of preterm births. The authors find that over 2010-20, an average of 13,262 premature births were recorded in China due to heatwave exposure. The study linked one-quarter of these early births to climate change.
Another profound impact of heatwaves is that they can exacerbate droughts, with knock-on impacts for agriculture.
Reuters reported last June that “China’s agriculture ministry said…searing temperatures have adversely impacted summer planting and that fighting drought and protecting summer planting were arduous tasks”.
Droughts in 2024 hit more than 11 million people in China, with more than 1.2m hectares of affected crops and direct economic losses topping nearly 8.4bn yuan ($1.2bn), the Ministry of Emergency Management said in early 2025.
Heat-related economic losses could reach nearly 5% of China’s GDP by 2060, according to a recent guest post for Carbon Brief. Authors Prof Guan Dabo and doctoral student Sun Yida from Tsinghua University wrote:
“By 2060, China’s heat-induced economic losses could total about 1.5% of total GDP under 1.5C of global warming, 3% under 2C of warming and 4.9% under 2.5C of warming.”
Those predicted losses include “indirect economic losses”, which “could be due to changes in production, consumption or employment” in the global supply chain, including crop failures and labour slowdowns, they explained.
The figure below, based on their study, shows Chinese GDP losses under three different scenarios of future emissions, called “shared socioeconomic pathways” (SSPs).
The SSP1-1.9, SSP2-4.5 and SSP5-8.5 scenarios project average global temperature rises of around 1.5C, 2C and 2.5C by mid-century, respectively.
Economic losses are split into indirect losses (dark blue), labour losses (blue) and health losses (light blue).
Sectors such as the extractive industries, construction and non-metallic manufacturing “could see the highest losses” of about 4.6-6.4% of their “value-added” – the increase in worth of a product or service as it moves through different stages of production – largely because they are in Chinese “regions with significant warming”, according to Guan and Sun.
Those industries also have close business connections with south-east Asia, Africa and South America, which are “expected to face heightened exposure to production volatility caused by high temperatures”, they add.
The total economic loss globally could reach up to 4.6% by 2060, according to their study, and manufacturing-heavy countries such as China and the US, in particular, could be “strong[ly] hit”.
Other than manufacturing, electricity supplies in China have also been frequently reported to be affected by hot days.
Chinese news outlet China Business Network reports that China’s National Energy Administration said last year that summer was the hardest time to ensure sufficient electricity supply during a year and that extreme weather would make the supply even harder.
For 2025, China’s State Grid Corporation expected maximum electricity demand to exceed 1,200 gigawatts (GW), a new record.
Dr Muyi Yang, senior energy analyst at thinktank Ember, tells Carbon Brief that “when temperatures soar, electricity demand spikes – mainly due to air conditioning – and that can stretch the grid, especially in already tight systems”.
Biqing Yang, energy analyst at Ember, adds:
“In the third quarter of last year, for example, China’s residential electricity consumption rose significantly, by 17.8% year-on-year, largely due to elevated temperatures…It is clear that we are now entering an era [w]here climate change is having a real-time impact on our energy system.”
China’s electricity demand reached a new record in July 2025 after year-on-year growth of 8.6%, consuming more power in one month than Japan did in all of 2024, according to David Fishman, Shanghai-based principal at consultancy the Lantau Group.
The “staggering” July 2025 figures – including another 18% year-on-year rise in residential demand, partly due to rising household incomes, as well as air conditioning use – illustrates the impact of climate change on China’s power sector, Fishman writes on LinkedIn:
“We know it’s hot out and everyone knows every summer the intense heat seems to last for longer and longer. But these power consumption numbers are telling a story about China’s climate patterns like few other datasets can…and it’s a scary story.”
Yang, Chen and Cai tell Carbon Brief that it is important for China to adapt to the rising temperature and intensive heatwaves.
Chen specifically describes “successful” forecasts and early warnings as “critical” , saying that they are the “very first step toward adaptation”.
In his LinkedIn post, Fishman notes that the rapidly rising demand for electricity, including as a result of growing air conditioning use, also poses a “considerable challenge to China’s ability to meet rising demand solely with clean power sources”.
How is China adapting to heatwaves?
In recent years, China has implemented more and more policies aimed at adapting to heatwaves.
For example, weather forecasts and heatwave alerts have been provided.
Central and local governments have also issued labour policies aimed at protecting workers against extreme heat.
Under a policy from the Ministry of Human Resources and Social Security, for instance, outdoor works are not expected to be undertaken when temperatures exceed 40C. In addition, outdoor working hours should be shorter than six hours when the temperature is 37-40C.
Similarly, school students in some cities, such as Wuhan and Chengdu, have been advised to study from home during hot days in recent years.
Since 2021, the city of Tianjian has been sending text warnings of heatwaves to its residents, reminding people of the health risks it poses. The messages, according to Southern Metropolis Daily, warn that strokes might be triggered in the coming hot days and advises people to avoid outdoor activities and take medication if needed.
These text reminders have “significantly” reduced the number of hospitalised people in Tianjin, saving the city 140m yuan ($19.5m) since being introduced, adds the outlet.
In 2013, the central government published its first “national climate change adaptation strategy” – an attempt to implement the “clear requirement” of “enhancing our ability to adapt to climate change” included in the 12th “five-year plan” (2011-15).
In the latest version for 2035, heatwaves appear in sections related to the power sector, as well as agriculture and health.
The strategy aims to “improve” and “reinforce” nationwide “labour protection standards”, as well as “work system[s] that adapt to change and reduce agricultural disasters”. Its purpose is also to ensure the energy and electricity sectors’ abilities to “withstand extreme weather and climate events” in relation to heatwaves.
The strategy says that “health-risk assessment guidelines” and public health-related “implementation plans for adaptation under major extreme weather and climate events”, such as heat and heatwaves,in “various regions”, will be developed.
Last year, following the release of the latest overall adaptation strategy, China published the “national climate change health adaptation action plan (2024-30)”.
Cai calls the document a “very very important” blueprint for health risk management, bringing together a range of organisations, including hospitals, to form a “system related to climate change and health” that has “monitoring and early warning capabilities”.
She adds that this plan will also see heat-health alerts being issued nationwide:
“It is worth mentioning that the National Administration of Disease Control and Prevention and the China Meteorological Administration signed a joint agreement [in May 2025] on issuing [nationwide] health alerts – and that the first product is related to heatwaves.”
Ember’s Yang says that in terms of electricity, China is moving toward building a “‘new electricity system (新型电力系统)’ that is more compatible with high shares of renewables”. But, he adds, the old “planning psychology” needs to change so that it can better cope with extreme heat:
“Traditionally, the mindset has been very supply-driven – just keep adding enough generation and network capacity to meet demand…[With the new system] the demand side has to become an active player – a prosumer – that can actually support grid reliability.
“For example, during extreme heat, instead of just ramping up supply, we should also be encouraging users to reduce or shift their electricity use during peak hours, using price signals or incentives…This is the essence of what we call ‘coordinating generation, grid, load, and storage’ (源网荷储一体化) – a system that works together [and works] more efficiently and flexibly.”

Q&A: How China is adapting to ‘more frequent and intense’ heat extremes
Cristina Rumbaitis del Rio is a senior advisor on adaptation and resilience with the United Nations Foundation and Mattias Söderberg is global climate lead at Danish NGO DanChurchAid.
Recent extreme events – from wildfires and heatwaves in Europe to flash flooding following a glacier collapse in Nepal – have shocked and devastated communities, bringing years of warnings about such climate impacts to the doorstep of communities around the world.
One thing is certain: the new climate reality is here – and the adaptation strategies designed for yesterday’s world are no longer sufficient.
Attribution science has since shown that the hotter and more frequent heatwaves we’re experiencing around the world would have been virtually impossible without today’s high concentrations of greenhouse gases in the atmosphere. Climate shocks are now so severe that they reverberate through supply chains, food and water systems, financial markets and the movement of people.

They must be a catalyst for a new way of thinking about adaptation and resilience, and how we finance solutions that work. A failure to invest in adaptation in one region can create costs far beyond it, which is why the concept of shared resilience is critical for leaders to grasp.
Investment not charity
At the UN General Assembly (UNGA 81) this month, leaders have an opportunity to translate today’s urgency into concrete commitments on adaptation and loss and damage finance ahead of COP31.
Those commitments are needed to underpin global stability, shared prosperity and human security. Governments should use this moment to show what a new response looks like: finance that reaches communities faster, supports locally grounded solutions, strengthens national systems, and helps countries prepare before the next shock arrives.
If we want sustained economic growth, food and water security, and resilient and prosperous societies across every region, adaptation must be at the heart of today’s development and security agenda. It cannot be just a future planning consideration or a narrow issue for climate ministries. Adaptation is now everyone’s business – and it must be financed fast and fair.
UN Secretary-General António Guterres has repeatedly framed climate finance as an investment rather than charity, warning that “a world in climate chaos cannot be a world at peace” and describing human security as freedom from the chronic and sudden disruptions that climate change multiplies.
What’s more, adaptation delivers a real return-on-investment, with researchers estimating that every dollar invested produces $10 in benefits, saving lives, protecting livelihoods, and reducing the costs of future disasters.
Hitting adaptation limits
The urgency to scale adaptation systematically is growing. The newly released “Limiting Overshoot” report from the UN Environment Programme (UNEP) confirms what scientists have long warned: exceeding global warming of 1.5C is now unavoidable under current policies. Yet, how high temperatures rise – and how long the world remains above the 1.5C threshold – will determine whether communities, economies and entire ecosystems can keep pace.
There are limits to adaptation. When we breach those limits, lives and livelihoods are lost, and people and ecosystems suffer greatly. We cannot simply build yesterday’s infrastructure a little stronger and assume it will be enough.
Nepal flood destruction shows “limits to adaptation”, scientists say
We need to fundamentally change the systems that determine how societies anticipate, absorb and recover from both immediate and evolving non-linear climate shocks. This includes transforming physical systems, such as infrastructure, and the governance systems that affect where and how we live to how we maintain our health and wellbeing.
Finance today is nowhere near the scale of the challenge.
The UNEP “Adaptation Gap Report 2025” estimates the shortfall in adaptation finance in developing countries at $284 billion–$339 billion a year – roughly 12 to 14 times current international public flows of around $26 billion. That gap is a development, economic and human security problem, especially for the most vulnerable populations who have contributed the least to causing the climate crisis.
Building resilience into financial systems
There are already signs of what a more systemic adaptation response could look like. Communities around the world are delivering practical solutions at local level, even as adaptation finance remains notoriously, and appallingly, difficult to access. Cyclone-resistant homes, local forecasting capacities, drought-resistant crops, heat insurance for pregnant informal workers and mangrove restoration are rooted in local knowledge and lived experience, while delivering benefits far beyond the communities where they originate from.
But local innovation alone is not enough; the systems around it need to be resilient too.
Jamaica offers one example. The country has built a multi-layered disaster-risk financing framework, including a catastrophe bond and contingency funds, through sustained fiscal discipline and proactive investment. Its debt-to-GDP ratio fell from around 147% in 2012 to around 62% in 202-25. That groundwork matters when disaster strikes.
Hurricane Melissa’s destruction shows need for climate resilience push
Following Hurricane Melissa, Jamaica was able to secure billions of dollars in reconstruction financing from multilateral banks – finance that might otherwise have been much harder to access. The lesson is clear: resilience can be built into the financial architecture of a country before a crisis arrives. That is the shift we now need to make at scale.
The foundations already exist – in Kingston’s fiscal reforms, in early-warning systems from the Sahel to the Pacific, and in every community that adapted before disaster struck. What is still missing is the political will, and the finance, to take what works and put it to work everywhere, at the speed our world’s new climate reality demands.

Climate Change
Framing the climate science debate as a binary battle isn’t just wrong – it’s dangerous
Lidy Nacpil is the coordinator of Asian Peoples’ Movement on Debt and Development (APMDD).
Recent reporting on international climate negotiations has highlighted a sharpening divide within civil society and multilateral diplomacy. A troubling, simplistic narrative has taken root: that the UN climate process is witnessing a binary struggle between defenders of science and those attacking it.
This framing is not only inaccurate; it is dangerous. Characterising a substantive methodological and political debate in these terms misdiagnoses the stakes and stirs conflict instead of clarity.
No one disputes that climate action must rest on science. Science tells us what has led us to the climate crisis – the accumulation of historical emissions – and how much carbon budget remains if we are to keep temperature rise below 1.5C. It tells us how much global emissions must drop, and how fast. Science is also essential in assessing each country’s historical contribution to the accumulation of greenhouse gases in the atmosphere.
Responsibility, however, must also be based on capacity. For those who generated the largest share of historical emissions, that capacity includes the enormous wealth and economic power accumulated through the same fossil-fuel-intensive development that generated those emissions.
As science comes under attack at UN talks, climate movement splits over how to respond
While principles that should guide human action aren’t scientific questions – they are matters of values – applying them to real-world problems requires scientific grounding. Equity recognises the scientifically established reality of differentiated responsibilities among countries and within societies. Putting equity into practice demands scientific rigour.
Scrutiny of IPCC models
Today, critics are scrutinising the assumptions and frameworks behind the Intergovernmental Panel on Climate Change’s Integrated Assessment Models (IAMs), used to project future scenarios and map global mitigation pathways. These concerns centre squarely on equity and justice.
The economic, technological and policy assumptions used in IAM scenarios are normative choices rather than scientifically prescribed or neutral facts. These include choices about discount rates, economic growth, energy demand, technology costs, carbon prices, land availability and the regional location of mitigation. Many IAM scenarios reproduce existing global inequalities rather than transform them. Questions about transparency, representativeness and diversity in the scientific process are deeply urgent.
Most IAM scenarios are built primarily around global cost-effectiveness – directing emissions reductions to places where mitigation is modelled as cheapest rather than allocating effort according to historical responsibility, capacity and development needs.
The resulting pathways allow developed countries to retain disproportionately high levels of energy and fossil-fuel consumption while requiring developing countries to undertake substantial mitigation and carbon removal, including land-based measures that threaten food security and local development.
Northern models often assume uniform access to cheap financing. In reality, Global South economies face far higher capital costs, driving up the price tag of rapid infrastructure shifts.
Constraints on development space
Scenario constraints also limit the development space poorer nations need without guaranteeing adequate climate finance. When models treat profoundly unequal starting points as uniform baselines, policy pathways lock in global inequality under the banner of scientific objectivity.
Pointing out these structural flaws isn’t rejecting science. It is essential scientific scrutiny aimed at producing stronger, fairer, and more actionable results.
Science ‘under attack’ from fossil fuel interests at UN climate talks
The fight is not about whether we want to keep temperature rise below 1.5C, but about how we get there. A pathway can be technically compatible with 1.5C or 2C while still being deeply unequal in who gets to consume energy, who must reduce emissions, and whose development is constrained. Temperature compatibility alone does not make a pathway fair.
Critiquing IAM scenarios from an equity perspective is neither an attack on the Intergovernmental Panel on Climate Change (IPCC) nor an attack on science. Rigorously examining IPCC reports – their substance, assumptions, and processes – is an acknowledgement of the IPCC’s importance and entirely consistent with scientific method.
Tensions over AR7 timing
There is a separate but related tension over the cycle and timeline of the IPCC’s Seventh Assessment Report (AR7). Some governments and civil society voices advocate completing its Working Group reports in time to feed directly into the UN’s Second Global Stocktake in 2028.
The motivation makes sense: policymakers need timely science. But several developing-country negotiators and researchers have warned that meeting that deadline could severely disadvantage the Global South.
Funding gap threatens next round of IPCC climate science reports, chair warns
Global North authors and institutions remain disproportionately represented in the research underlying IAM assessments. Developing-country researchers often work with fewer institutional resources, smaller research budgets, and less administrative support. Accelerated publishing and assessment schedules can further limit their ability to generate, submit, and peer-review research in time for inclusion.
The AR7 timeline concerns boil down to inclusivity, representation, and equity. Requiring the IPCC to meet tight political calendars without ensuring meaningful support and participation for developing-country researchers risks reproducing the very inequalities being challenged.
Cooperation requires equity
Political interests are indeed at work in UNFCCC negotiations and must be surfaced. Bad-faith actors seek to evade fossil-fuel phase-outs or shirk climate-finance obligations. Many developed country parties are guilty of both, including those who style themselves as “Friends of Science.”
We must not lump legitimate scientific critiques raised by several Global South researchers and many civil society organisations concerning representation, economic assumptions and fair-share accounting together with obstructionism. Doing so risks misrepresenting and delegitimising critical scientific work and Global South equity and justice perspectives.
The climate movement is strongest when it aligns rigorous science with global equity and justice. Achieving the Paris Agreement’s goals requires robust science that fully integrates the experiences, economic realities and academic contributions of the Global South. Effective climate action also requires international cooperation, and without equity, such cooperation cannot be sustained. We do not have to choose between science and equity. We need both.

Framing the climate science debate as a binary battle isn’t just wrong – it’s dangerous
More than 300,000 solar panels and 120 battery containers are helping to power Africa’s largest copper mine with continuous clean energy in the Democratic Republic of the Congo, as miners turn to solar as an alternative to expensive diesel and energy imports.
The project at the Kamoa Copper mine in the south of the DRC, which became operational last month, is one of the largest solar and battery facilities generating baseload power on the continent.
The clean electricity is displacing millions of litres of polluting diesel and costs less than a fifth of the price of generator power per kilowatt hour, the mining company said.
The project is part of a massive solar deployment across the continent. Recent data from global energy think-tank Ember found record solar capacity of 17 GW will be installed in Africa this year – a 45% rise from 2025.
Installed by CrossBoundary Energy, a developer of distributed renewable energy systems, the solar-battery facility at the DRC mine is “proof of concept” that solar and battery systems can provide the reliable power at scale needed by remote industrial operations, Annebel Oosthuizen, managing director at Kamoa Copper, told Climate Home News in an interview.
“There’s always been this perception in the DRC that solar isn’t ideal because it is raining half of the year. But it’s perfectly ideal. We are seeing a lot of interest from other mines that are still depending on generators and power imports,” she said.
Mining drives solar and battery surge
Like Kamoa Copper, a growing number of miners in the DRC are looking to solar power to compensate for the country’s chronic energy deficit at a lower cost as global diesel prices hit record highs amid ongoing attacks on oil infrastructure in the Middle East.
As a result, the mining sector has become a key driver of the country’s growing clean energy demand and one of the biggest importers of large-scale solar equipment.
Ember found the DRC is set to install a record 1.7 gigawatts (GW) of solar panels this year – a 544% increase compared to 2025 and the equivalent of adding more than 60% of the country’s entire 2023 grid capacity.
The deployment of combined solar and battery storage solutions to deliver stable energy supplies to mines has also caused battery imports to surge. In dollar terms, the DRC’s imports of batteries from China far exceeded that of solar in the year to June 2026, according to Ember.
A crippling power deficit
The DRC holds significant energy resources and some of the world’s largest reserves of the minerals required to manufacture clean energy technologies. It is the world’s largest producer of cobalt, which is needed to make batteries, and Africa’s top producer of copper – a metal sought after for its electrical conductivity which is pivotal to the world’s electrification efforts.
Yet just 22.5% of the DRC’s population had access to electricity in 2024 – one of the lowest rates in the world, according to the World Bank. And as mining expands and more of the minerals extracted are being processed in the country, unreliable power supply has become a major constraint for the sector, which contributed to more than a quarter of the country’s GDP in 2024, excluding oil and gas.
The country has enormous hydropower potential, with the hydroelectric potential of the Congo River estimated at around 100 GW. But only a fraction is being harnessed.

Still, virtually all of the DRC’s grid-connected electricity is generated by hydropower by the state-owned utility, Société Nationale d’Électricité (SNEL).
The electricity then has to be transported more than 1,500 kilometres to reach the mining belt in the south – a challenge made more difficult by ageing grid infrastructure and limited transmission capability. SNEL did not respond to a request for comment.
“It is estimated that there’s around a 1 GW energy deficit for the DRC mining sector,” said Matt Tilleard, CEO of CrossBoundary Energy, which owns the solar and battery equipment at the Kamoa Copper mine and provides the power as a service.
“The interest in solar from the mining industry is not theoretical – it is already translating into large-scale solar and battery procurement for mining operations in the region,” he added.
Solar displaces gas, saves energy costs
The facility installed by CrossBoundary is part of a plan by Kamoa Copper to supply more of the electricity it needs with solar energy and batteries as its operations expand, a faster solution than relying on harder-to-build hydropower projects.
“Our processing capacity has increased drastically over the last couple of years. We’ve constructed the largest copper smelter in Africa and that is so power-intensive,” said managing director Oosthuizen.
A joint venture between Canadian firm Ivanhoe Mines, Chinese company Zijin Mining Group and the DRC government, the mine needs 235 megawatts (MW) of power, which is expected to nearly double to 450 MW in the next five years.
Kamoa Copper currently receives 100 MW from state utility SNEL – “and the rest we have to find a solution for”, said Oosthuizen.
Another 30 MW solar and battery baseload facility is expected to come into operation this month, enabling around 25% of the mine’s power needs to be generated by solar energy. An additional 60 MW of continuous solar power will be added by the end of 2027, and the company is exploring options for more solar capacity and two hydropower projects.
The operational 30 MW of clean electricity provided by CrossBoundary Energy will power pumps that prevent 400 million litres of water from flooding the underground mine every day.
In August alone, the facility has reduced the mine’s diesel consumption by around four million litres, generating an estimated $11 million dollars in savings at current diesel prices, Oosthuizen said.
The mine still relies on generators to meet a 20-40 MW deficit and to power the trucks used in the mine, which Oosthuizen said would be difficult to electrify in the next five years because the technology isn’t yet ready to operate in the mine’s tough and wet conditions.
Avoiding a two-speed transition
To prevent a major imbalance between industrial players’ access to clean, reliable energy and the millions of Congolese who remain without power, the government requires private electricity producers to reserve at least 10% of their generated power for local communities living near rural production sites.
Delivering this, combined with rural electrification, mini-grid development and national grid expansion, is critical to prevent a two-speed energy transition that leaves people behind, said Catherine Mukobo, head of ACERD, the Congolese Association for Renewable and Decentralised Energies.
“Without implementing these policies, the DRC could get in a situation where mines have access to abundant modern energy while a large part of the population remains without electricity,” she said.
