China's solar power capacity surpasses coal for the first time

China's National Energy Administration has called this a historic milestone — although coal still remains the undisputed leader in actual electricity generation.

The gist

• China's installed solar power capacity has exceeded coal-fired generation capacity for the first time in history — according to the National Energy Administration (NEA), by the end of July this figure reached 1.286 billion kW versus 1.285 billion kW of coal capacity.
• For the first time in over a century since the birth of China's energy industry, coal has ceased to be the largest source of generation by installed capacity; in the first half of 2026, coal's share in electricity production fell below 50% for the first time.
• However, in terms of actual output, coal still maintains its lead: solar power generated 802.4 billion kWh in the first seven months of 2026, up 15.5% year-on-year, but that is only about 13% of the country's total electricity consumption.
• In July alone, China commissioned 13.73 million kW of new solar capacity, and investments in the sector over the next five years will exceed 2 trillion yuan (about $298 billion).

Capacity is not the same as output

A key detail that is easy to miss behind the headline: installed capacity and actual electricity generation are different metrics. A coal plant operates almost around the clock and delivers its rated capacity consistently, whereas solar generates energy only during daylight hours and with variable intensity. That is why, despite overtaking coal in installed equipment capacity, China's solar power currently provides only about 13% of the country's actual electricity consumption — coal, despite formally losing its capacity leadership, still generates several times more electricity.

A century-old pattern broken

Nevertheless, the energy administration openly emphasizes the symbolic significance of this milestone.

The NEA's official statement reads: "For over a century, since the birth of China's energy industry, the historical pattern in which coal-fired generation remained the largest energy source has now been broken."

This was preceded by another telling moment — in the first half of 2026, coal's share in China's total electricity generation fell below 50% for the first time. According to NEA representative Lin, the role of coal-fired generation is undergoing a profound transformation — from its traditional position as the primary energy source to a function of stabilizing backup for renewable capacity.

China remains the global leader in panel production

The growth of solar energy in China is driven not only by domestic demand but also by the country's status as the dominant global supplier of equipment — China accounts for about 80% of global solar module production, and the NEA describes China's manufacturing chain in this sector as the most complete and competitive in the world. The level of engineering ambition is also telling: the world's largest hybrid solar plant in the Hami desert, running on molten salt and generating electricity for up to 8 hours after sunset without a single lithium-ion battery — is also a Chinese project. In parallel, the country is investing heavily in modernizing its power grids, which is necessary for integrating rapidly growing solar and wind capacity — grid infrastructure investments in 2026–2030 are expected to exceed 5 trillion yuan (about $743.8 billion).

Why this matters for Kazakhstan

China's milestone is a telling contrast to Kazakhstan's own energy strategy, where solar and coal power are developing in opposite proportions. The country continues to bet on coal even in new projects — including the power supply for the "Data Center Valley" in Ekibastuz — while its own renewable energy program is still measured in hundreds of megawatts rather than gigawatts: Kazakhstan has commissioned 212 MW of new renewable capacity out of ten facilities planned for 2026. At the same time, it is Chinese state-owned energy holdings that increasingly act as owners and developers of Kazakhstan's renewable energy projects, making China's experience of transitioning from coal to solar not an abstract reference point but a practical example from a country whose technology and capital are already present in Kazakhstan's energy sector.

Author's conclusion

The milestone announced by China's energy administration matters not so much in itself — the figures of 1.286 and 1.285 billion kW are too close to speak of a decisive breakthrough — but rather as a symbol of the direction in which the world's largest coal economy is moving. While coal remains the actual backbone of China's power system in terms of output, the very fact that solar has overtaken it in installed capacity shows where the main investments of recent years have been directed — and this is something countries like Kazakhstan, which are still forming their own balance between traditional and renewable generation, should keep in mind.
