Sun Over Coal: China’s Power Grid Crosses a Century-Old Threshold

China’s National Energy Administration (NEA) confirmed on September 1–2, 2026 that installed solar photovoltaic capacity had overtaken coal-fired capacity for the first time — a reversal the agency itself called a “signature achievement” and a break from “the historical pattern of coal power serving as the largest power source.”

The announcement was picked up almost simultaneously by Chinese state media, global wire services, and outlets across Europe and Asia — from Xinhua-linked domestic coverage to Bloomberg, the South China Morning Post and Global Times in English, franceinfo and Swiss francophone outlets in French, several German business and news sites, Italy’s specialist clean-energy press, and Japanese financial commentary. The consistency of the figures across languages is itself notable: everyone is reading from the same NEA release.

The numbers

As of the end of July 2026, China’s installed solar capacity stood at roughly 1,286 gigawatts (GW) — some outlets cite 1,286 GW, others 1,288 GW, a rounding difference rather than a real discrepancy — split between about 704 GW of centralized, utility-scale solar farms and 582 GW of distributed (mostly rooftop) systems. Coal capacity, by comparison, stood at approximately 1,285 GW. Solar now accounts for 31.5% of China’s total installed generating capacity, edging past coal by the narrowest of margins on a metric that took decades to flip.

Generation figures tell a related but distinct story. Solar produced 802.4 billion kWh of electricity in the January–July 2026 period, up 15.5% year-on-year, and now supplies about 13% of China’s total electricity consumption — up 1.7 percentage points from a year earlier. Perhaps more strikingly, the NEA also disclosed that coal’s share of total power generation fell below 50% in the first half of 2026 (to roughly 49.7%), the first time that threshold has been crossed. Renewables overall made up about 24.6% of China’s energy mix in the same period.

Why capacity isn’t generation

Nearly every outlet that covered the story flagged the same important caveat: installed capacity is not the same as electricity actually delivered to the grid. Coal plants, unlike solar panels, can run around the clock regardless of weather or time of day, so despite now trailing in installed megawatts, coal still generates significantly more electricity overall than solar does. Xiamen University energy economist Lin Boqiang, quoted in Chinese coverage picked up internationally, framed it as coal “undergoing transformation, shifting from primary source to providing stable support as renewable energy backup” — a grid-balancing role rather than disappearing outright. German coverage was blunter about the limits of the milestone, noting coal remains strategically important to Beijing as a source of cheap, dispatchable power and even as chemical feedstock via coal gasification, which reduces China’s reliance on imported oil.

A milestone with a history

This is not China’s first such crossover. Japanese and international energy-transition commentary points out that China’s combined wind-and-solar capacity had already overtaken coal capacity back in March 2025, and non-fossil generation overall passed fossil generation on a broader accounting basis even earlier. What’s new in September 2026 is solar standing alone above coal — a sign of just how much the balance has shifted within the renewables mix itself, with solar now the single largest contributor.

A slowdown behind the milestone

One nuance emphasized in German-language coverage, and less visible in English-language headlines, is that the pace of new solar additions has actually cooled sharply in 2026. New installed capacity from January to July was reported down as much as 62% compared with the same period in 2025 — a hangover from a policy shift that ended guaranteed feed-in tariffs for new solar projects in mid-2025 in favor of market-based pricing, which triggered a rush to connect projects before the deadline and a lull afterward. In other words, China crossed this threshold on the back of a historic 2025 build-out rather than accelerating momentum in 2026 — a detail that tempers, without undercutting, the scale of the achievement.

The bigger picture

Italian energy outlet Rinnovabili put the milestone in global perspective: China alone installed roughly 315 GW of new solar capacity in 2025, more than half of all solar additions worldwide that year, and its total installed base now exceeds the combined solar capacity of every European Union member state put together (Europe stood at about 359 GW at the end of 2025). For a country that still burns more coal than the rest of the world combined and remains the largest single emitter of greenhouse gases, the NEA is framing this as proof of an accelerating “new-type power system” built around renewables — even as it acknowledges, in the same breath, that making solar “dispatchable and predictable” through storage and hybrid systems is the real work of the next five-year plan period, 2026–2030.
