Renewable Energy
China has just crossed a historic milestone in its electrical system: the installed capacity of photovoltaic energy reached 1,286 billion kW, surpassing for the first time the 1,285 billion kW of coal-fired plants and making solar the largest source in the country based on installed capacity. This achievement was reported by China.org.cn, with information from Xinhua News Agency and the National Energy Administration of China, and is based on data available up to the end of July 2026.
Moreover, the difference between the two sources is small in absolute terms—only about 1 million kW—but the symbolism is enormous. For decades, coal has supported China’s industrialization and occupied the center of its energy system. Now, however, the capacity of solar panels installed in deserts, rooftops, rural areas, industrial zones, and hybrid projects has managed to surpass the total power of fossil fuel-fired thermal plants.
Nevertheless, it is crucial to distinguish between installed capacity and actual generation. One gigawatt of solar does not produce electricity continuously over the full 24 hours, while coal-fired plants can operate for much longer periods. Therefore, this milestone does not mean that China is now producing more solar electricity than coal electricity. It shows that, in terms of nominal installed capacity, the country now has more photovoltaic capacity than thermal coal capacity.

The numbers released by the National Energy Administration show a narrow lead.
As of the end of July, China’s photovoltaic capacity reached 1,286 billion kW, equivalent to 1.286 GW.
Meanwhile, the installed capacity of coal-fired power plants stood at 1,285 billion kW, or 1.285 GW.
Thus, solar has taken the lead by an approximate margin of 1 GW.
In another country, such a small difference might seem statistically insignificant.
In China, however, the point is noteworthy because both bases exceed 1.2 terawatts each.
Consequently, the competition is happening on an energy scale that few power systems in the world can even approach.
This surpassing did not arise from a single project.
On the contrary, it is the result of years of accelerated installation.
China has simultaneously expanded large plants in deserts, distributed rooftop projects, rural systems, and industrial ventures.
Furthermore, the country has created vast domestic manufacturing chains for polysilicon, wafers, cells, modules, inverters, and electrical equipment.
This industrial scale has reduced costs and allowed photovoltaic capacity to grow much faster than conventional sources.
Thus, the expansion of renewable generation has ceased to represent merely an environmental policy and has begun to structurally alter the electrical matrix of large economies.
This is the most crucial point for correctly interpreting the news.
Installed capacity indicates how much a source could produce under certain conditions, and not necessarily how much it actually generates over a year.
Solar panels depend on light availability.
At night, their production drops to zero.
Moreover, clouds, location, season, and atmospheric conditions affect performance.
On the other hand, a coal-fired thermal plant can generate electricity for many consecutive hours as long as it is supplied and operational.
Therefore, even after losing its lead in installed capacity, coal continues to play a significant role in actual electricity generation in China.
The more accurate reading is different.
China did not shut down 1.285 TW of thermal plants.
Nor did it instantly replace coal with solar panels.
What happened was a shift in the capacity structure.
While the thermal fleet remains enormous, solar grew so rapidly that it surpassed it.
Thus, the milestone demonstrates where new investments are shifting.
At the same time, it shows how the matrix can coexist for years with rapidly growing new technologies and older sources still responsible for a significant share of the electricity supplied.
The transformation also depends on the manufacturing industry.
China concentrates a dominant share of the global production of photovoltaic components.
Consequently, the country can produce enormous volumes of modules at competitive costs.
This vertical integration helped accelerate internal projects.
Additionally, Chinese manufacturers export equipment to practically every continent.
Thus, China’s solar industrial policy has produced two simultaneous effects:
rapidly expanded its own energy capacity and transformed the country into the leading global supplier of the technology.
An important part of the expansion occurs in regions with large available areas.
Deserts in northern and western China have begun to host enormous energy bases that combine solar, wind, and long-distance transmission networks.
These ventures are able to install millions of panels in areas with high solar incidence.
On the flip side, there is a geographical challenge.
Much of the electricity demand is located in industrial and urban centers far away.
Consequently, building plants is not enough.
It is also necessary to transport electricity for hundreds or even thousands of kilometers.
As more solar capacity enters the system, the need to strengthen the grid increases.
Production varies throughout the day.
Moreover, certain provinces can generate far more electricity than they can consume locally.
Therefore, transmission, storage, digital control, and interconnection are becoming increasingly important.
China has already announced efforts to develop new types of electric grids to manage a more distributed matrix dominated by variable sources.
Thus, the next bottleneck may shift from simply manufacturing panels.
It may become integrating all this capacity without wasting energy.
This problem explains the race for storage.
During certain hours, large volumes of solar energy can enter the grid simultaneously.
However, early in the evening, production drops quickly while demand may remain high.
Batteries can store some of the electricity during excess periods and return it later.
Additionally, pumped-storage hydropower plants, flexible grids, and demand management also help.
The expansion of storage systems is expected to become even more relevant as variable renewables occupy larger shares of capacity.
China still considers energy security a priority.
Therefore, even while installing solar at a record pace, the country maintains a significant amount of thermal capacity.
Coal provides a strategic characteristic: it can generate in a controllable manner when fuel is available.
Thus, authorities can use it to offset times when solar and wind produce less.
This behavior explains an apparent contradiction.
China simultaneously leads the global expansion of renewables and global coal consumption.
In practice, it tries to transform the energy matrix without quickly abandoning the sources that ensure stability.
Imagine two plants with the same nominal power.
One of them produces for a large part of the 24 hours.
The other depends on the sun.
Although both have, for example, 1 GW of capacity, the annual amount of electricity can be quite different.
Therefore, comparing only installed gigawatts offers an incomplete view.
The indicator is extremely useful for measuring built infrastructure.
However, it needs to be accompanied by actual generation, capacity factor, and share in consumption.
In the Chinese case, solar’s victory in capacity is historic.
But the transition in generation will take longer.
Transforming 1.286 billion kW into another unit helps to visualize.
That amounts to 1.286 gigawatts.
Or 1.286 terawatt of photovoltaic capacity.
This number refers only to solar.
Thus, it does not include hydropower, wind, nuclear, gas, or coal.
The scale shows why any changes in China affect global statistics.
When Beijing adds several dozen gigawatts, that can be equivalent to the entire electrical system of smaller countries.
At the moment recorded by the data, solar has surpassed coal by just 1 GW.
However, the two sources are not growing at the same pace.
Photovoltaic capacity continues to receive huge volumes of new projects.
Conversely, the net expansion of coal tends to occur much more slowly relative to the existing base.
Consequently, if the recent pace continues, the gap could increase rapidly in the coming years.
The milestone of July may thus represent only the exact moment of the crossover.
The future distance may become much larger.
The energy transformation is also occurring within a massive economy.
China has set new goals to expand domestic consumption and aims to increase total consumer goods sales to about 60 trillion yuan by 2030.
This means more factories, appliances, vehicles, data centers, and infrastructure.
As a result, electricity demand will remain huge.
Therefore, renewable expansion is not just meant to replace old sources.
In many cases, it also needs to accommodate new consumption growth.
China has become the world’s largest electric vehicle market.
At the same time, millions of chargers add new loads to the system.
Each individual car consumes relatively little compared to a plant.
However, millions of vehicles connected to the grid change the scale.
Thus, solar, batteries, and smart grids begin to interact with automotive expansion.
The accelerated electrification of transport shows how the energy transition is not happening solely within the plants.
It also alters what consumes electricity.
Another crucial element is that expansion is ongoing.
Various solar and hybrid projects are still under construction.
Additionally, Chinese provinces continue to approve renewable capacity.
Therefore, the 1.286 TW recorded in July does not represent a ceiling.
They are merely a snapshot of that moment.
This detail emphasizes the significance of the milestone.
Solar surpassed coal while its own expansion is still underway.
Large installations in arid regions attract attention due to their scale.
However, China employs various other configurations.
There are projects over reservoirs.
There are also systems that combine aquaculture and photovoltaic generation.
Furthermore, factories and homes receive distributed installations.
A photograph released by Xinhua in August showed workers maintaining a hybrid project of aquaculture and photovoltaic generation in Yangzhou, illustrating this diversity.
Thus, the expansion does not depend on a single model.
This logic appears in various projects.
Industrial rooftops become small power plants.
Reservoirs host floating structures.
Agricultural areas can combine food and energy production.
Moreover, desert regions gain massive renewable corridors.
The advantage of this diversity lies in the ability to bring part of the generation closer to consumption centers.
On the flip side, each configuration has its own costs, environmental impacts, and technical challenges.
Even with over 1.2 TW of solar capacity, China may continue to approve thermal plants.
This seems contradictory only when capacity and generation are treated as the same thing.
A thermal plant can serve as a power guarantee during periods of low renewable generation.
Therefore, Chinese authorities view part of the new thermal plants as support for the system.
Still, as more storage and flexibility enter the grid, the need to operate these units for extended hours may decrease.
Thus, the role of coal may change before its capacity disappears.
When a region produces more electricity than it can consume or transport, the operator may need to limit generation.
This phenomenon is known as curtailment.
The higher the solar capacity, the greater the risk of excess generation at certain times.
Therefore, China invests in ultra-high voltage transmission lines and energy storage.
Additionally, it aims to create markets and systems capable of shifting consumption to times of higher renewable production.
Consequently, the next stage of the solar revolution may rely less on adding panels and more on making better use of what has already been installed.
Producing at a massive scale has lowered prices.
However, it also caused oversupply during certain periods.
Chinese manufacturers face decreasing margins and intense competition.
Thus, energy expansion helps absorb part of the domestic production.
Simultaneously, it consolidates more efficient companies and pressures less competitive manufacturers.
This cycle demonstrates how industrial policy and energy policy go hand in hand.
For years, the country was already the world leader in manufacturing photovoltaic equipment.
Then, it became the largest market for installations as well.
Now, solar has reached another symbolic milestone.
It has become the largest source of electricity in the country by installed capacity, surpassing coal, a fuel historically associated with Chinese industrialization.
This change does not mean that coal has disappeared.
It occurs because another technology has grown quickly enough to overtake it.
In the end, the entire story can be summed up in two numbers.
On one side:
1.286 billion kW of photovoltaic capacity.
On the other:
1.285 billion kW in coal-fired thermal plants.
The difference is minimal.
However, the order has reversed.
For decades, coal sat at the top.
Now, at least when comparing installed capacity, the sun holds that position for the first time.
Still, China’s transition is far from over. The country needs to expand grids, storage, and flexibility while continuing to sustain an economy that consumes enormous volumes of electricity.
Thus, the milestone of July does not signify the end of coal.
It represents something different and equally significant: the first time that China has built more capacity to convert solar light into electricity than capacity to produce energy by burning coal.
Did you expect that China had already installed more solar capacity than coal capacity, or did you think that this surpassing would still take many years to happen?
