China's Coal Power Climbs for a Fourth Straight Month as Wind and Nuclear Falter

China's Coal Power Climbs for a Fourth Straight Month as Wind and Nuclear Falter A weather-driven coal rebound is testing the claim that China's emissions have peaked, even as renewable build-out continues at record pace. China's coal-fired generation rose for a fourth consecutive month in April, according to a snapshot published by the Centre for Research on Energy and Clean Air on (2026-05-21), as weak wind, subdued solar output and extended nuclear refuelling outages forced thermal plants to cover demand. Total power generation is estimated to have climbed 6.6% year-on-year.¹ That matters because it complicates the story that took hold earlier: that clean energy had finally bent China's emissions curve downward. Carbon Brief analysis reported on (2026-05-19) found that the growth in clean power had pushed national CO2 emissions down 1.6% year-on-year in the first quarter of 2025, the first such fall driven by renewables rather than by weak demand.⁶ The Economist went further on (2026-05-17), arguing China's carbon emissions may already have peaked.⁸ The April numbers show how fragile that turn is. When the weather stops cooperating, coal fills the gap. Oilprice reported on (2026-05-19) that China lifted coal and gas power generation by 3.1% in April from a year earlier as wind and nuclear output fell, with some reactors down for maintenance.⁷ This is not a policy reversal. It is the grid doing what it was built to do. And China keeps building. Thermal power commissioning in the first quarter surged more than 160% year-on-year to a record high, the CREA data showed, evidence that the coal fleet is still expanding even as clean capacity scales.¹ Muyi Yang, a senior analyst at the think-tank Ember, called it a "build before breaking" approach in comments to AFP reported on (2026-05-19).⁵ Clean capacity is scaling too, just unevenly. Solar additions fell 31% year-on-year in the first quarter against a very high base in the same period of 2024, though they stayed above first-quarter 2023 levels, while wind additions rose 8%.¹ Battery output jumped 55.6% year-on-year in April, supported by storage demand and exports.¹ The bottleneck is no longer building clean power but using it. The Economist noted on (2026-05-17) that China still needs power-market reform to dispatch renewable generation where it is needed, and that a politically powerful coal lobby is resisting.⁸ Imports add another wrinkle. Shipping disruptions through the Strait of Hormuz weighed on China's energy imports in April, with crude oil down around 20% and natural gas down about 13% year-on-year, the CREA snapshot showed, a fossil-fuel crunch that also pressured the chemical industry.¹ On coal itself, the trend is toward self-sufficiency. Domestic production slipped 1% in the latest month to 385.63 million tonnes, down from an all-time high reached in March, Reuters reported on (2026-05-20), with output over the first four months essentially flat at 1.58 billion tonnes.² Imports are falling faster. They dropped 6% year-on-year in March 2025 to a historic low as domestic supply surged and prices hit four-year lows, with analysts citing weak demand, high port inventories and narrowing import margins.⁴ The scale is the point. China burned 4.9 billion tonnes of coal last year, more than half the world's total, the Economist reported on (2026-05-19).³ Its annual electricity generation has grown about 6% a year since 2014, and electricity already meets close to 30% of final energy demand, a higher share than in the EU or the United States and still rising.³ A plateau at that scale still leaves an enormous baseline. So the question for traders is whether April's coal rebound is a weather blip or a sign that demand growth keeps outrunning clean supply. Near-term signals lean bearish on coal demand across the cycle, but the record thermal commissioning suggests Beijing is hedging against exactly the kind of shortfall April delivered.¹ Watch the next monthly snapshot. If wind and nuclear recover and clean power reclaims demand growth, the peak thesis survives. If coal logs a fifth straight monthly gain, the plateau starts to look like a pause.¹
