China is simultaneously the world’s largest investor in renewable energy and the world’s most prolific builder of new coal-fired power plants. This seeming contradiction has puzzled energy analysts, climate advocates, and policymakers for years. In 2024, as China added more solar capacity than the rest of the world combined and continued to dominate global wind turbine manufacturing, it also approved and began constructing dozens of new coal plants. Understanding why requires a deep examination of China’s energy security imperatives, its provincial governance structures, and the brutal physics of keeping the lights on in the world’s second-largest economy.
The numbers are staggering on both sides of the ledger. According to reporting highlighted by Slashdot, China continues to greenlight new coal capacity even as its renewable energy installations break records year after year. In 2023, China installed roughly 217 gigawatts of solar power — more than double the previous year and more than the entire rest of the world combined. Its wind installations similarly dwarfed those of other nations. Yet in that same period, China permitted more new coal plant capacity than at any time since 2015, according to data from the Centre for Research on Energy and Clean Air (CREA) and Global Energy Monitor.
The Reliability Imperative: Why Renewables Alone Can’t Keep China’s Grid Stable
The fundamental tension at the heart of China’s energy strategy is one of reliability versus ambition. Solar panels generate electricity only when the sun shines, and wind turbines only when the wind blows. China’s electricity demand, however, is relentless and growing. The country’s total electricity consumption rose by approximately 6.7% in 2023, driven by industrial expansion, the rapid adoption of electric vehicles, and the electrification of heating systems. This growth in demand is not seasonal or predictable in ways that align neatly with renewable generation profiles.
China experienced this vulnerability firsthand during the power crises of 2021, when a combination of coal shortages, surging industrial demand, and drought-reduced hydropower output led to rolling blackouts across multiple provinces. Factories were forced to shut down, traffic lights went dark, and residential buildings lost power. The political fallout was severe. For China’s leadership, energy security is not merely an economic concern — it is a matter of social stability and regime legitimacy. The memory of those blackouts continues to drive policy decisions in Beijing and provincial capitals alike.
Provincial Politics and the Coal Construction Machine
One of the most underappreciated factors driving China’s continued coal buildout is the decentralized nature of its energy approval process. In 2014, Beijing delegated the authority to approve new coal plants to provincial governments. This decision, intended to streamline bureaucratic processes, had the unintended consequence of unleashing a wave of new coal projects. Provincial officials, whose career advancement is often tied to economic growth metrics and employment figures, found coal plants to be attractive investments. A new coal plant means construction jobs, ongoing operational employment, and a reliable source of tax revenue for local governments.
The incentive structure at the provincial level often runs counter to Beijing’s national climate commitments. While President Xi Jinping has pledged that China will reach peak carbon emissions before 2030 and achieve carbon neutrality by 2060, provincial leaders operate on much shorter political timelines. A governor or party secretary who approves a coal plant reaps the economic benefits during their tenure, while the carbon consequences materialize over the plant’s 30- to 40-year operational life. This misalignment between national climate goals and local economic incentives is a structural problem that Beijing has struggled to resolve.
The ‘Capacity Factor’ Problem: China’s Coal Plants Are Running Less Than Ever
Critically, many of China’s newer coal plants are not operating at full capacity — or anywhere close to it. The average capacity factor of Chinese coal plants has fallen to around 50%, meaning they generate electricity only about half the time they theoretically could. This is a dramatic decline from historical norms and reflects the growing share of renewables on the grid. In many provinces, coal plants increasingly serve as backup generators — sitting idle when solar and wind output is high, then ramping up during cloudy, windless periods or during peak evening demand when solar generation drops to zero.
This shift in the role of coal from baseload generation to peaking and backup power is significant but also economically precarious. Coal plants with low utilization rates struggle to cover their fixed costs, leading to financial losses for operators. In response, Chinese regulators have begun implementing capacity payment mechanisms — essentially paying coal plant owners to keep their facilities available even when they are not generating electricity. This model mirrors approaches used in Western electricity markets, where natural gas peaker plants serve a similar function. The difference is scale: China’s backup coal fleet is enormous, and the financial commitments required to maintain it are correspondingly vast.
Energy Storage: The Missing Piece of the Puzzle
The obvious solution to the intermittency problem — large-scale energy storage — remains insufficient to replace coal’s role as a reliability backstop. China is the world’s largest producer of lithium-ion batteries and has deployed more grid-scale storage than any other country. But the mathematics of replacing coal backup capacity with batteries remain daunting. A single large coal plant can generate 1,000 megawatts of power continuously for days or weeks. Replicating that capability with batteries would require enormous installations at costs that, while declining rapidly, are still prohibitive at the scale required.
Pumped hydro storage, which uses excess electricity to pump water uphill and then releases it through turbines when power is needed, is another option China is pursuing aggressively. The country has more pumped hydro capacity under construction than the rest of the world combined. But these projects take years to build and are constrained by geography — they require specific topographical features that are not available everywhere. Until storage technology catches up with the pace of renewable deployment, coal will continue to serve as China’s de facto energy insurance policy.
The Climate Math: Can China Peak Emissions While Building Coal?
Despite the continued coal buildout, there are reasons for cautious optimism about China’s emissions trajectory. The sheer volume of renewable capacity being added to the grid means that coal’s share of total electricity generation is declining, even as absolute coal capacity grows. In 2023, renewables accounted for more than 50% of China’s installed power generation capacity for the first time — a milestone that would have seemed unthinkable a decade ago. If current trends continue, analysts at Bloomberg New Energy Finance and the International Energy Agency project that China’s carbon emissions could peak as early as 2025, well ahead of the official 2030 target.
The key variable is whether China’s electricity demand growth continues to outpace the addition of clean energy sources. If economic growth slows — as many economists expect — the surplus of renewable capacity could displace coal generation more rapidly than current models predict. Conversely, if demand growth accelerates due to factors like widespread AI data center construction or faster-than-expected industrial electrification, coal plants could see their utilization rates stabilize or even increase.
What Western Observers Often Get Wrong
Western commentary on China’s coal buildout frequently falls into one of two traps: either dismissing China’s renewable energy achievements as greenwashing while focusing exclusively on coal, or ignoring the coal buildout entirely while celebrating China’s solar and wind records. The reality is far more nuanced. China is engaged in a massive, parallel buildout of both clean and fossil fuel energy infrastructure, driven by a pragmatic assessment that the transition to a fully decarbonized grid will take decades and that energy security cannot be compromised during that transition.
It is also worth noting that China’s newest coal plants are significantly more efficient than older facilities and than most coal plants operating in other developing nations. Many are ultra-supercritical units that burn less coal per unit of electricity generated and produce fewer emissions per megawatt-hour. China has also been retiring older, less efficient coal plants, though the pace of retirements has not kept up with new construction. The net effect is a coal fleet that is growing in total capacity but improving in average efficiency — a dynamic that complicates simple narratives about China’s coal addiction.
The Road Ahead: Stranded Assets and the Trillion-Dollar Question
The ultimate risk of China’s dual-track energy strategy is the creation of stranded assets — coal plants that become economically unviable long before the end of their designed operational lives. If battery storage costs continue to fall at their current trajectory, and if renewable energy costs maintain their downward trend, the economic case for keeping coal plants operational — even as backup — could evaporate within 10 to 15 years. China could find itself with hundreds of billions of dollars’ worth of coal infrastructure that is too expensive to run but too politically sensitive to shut down.
Beijing appears to be aware of this risk. Recent policy signals suggest a growing willingness to tighten controls on new coal approvals and to accelerate the deployment of storage and grid infrastructure. The National Energy Administration has issued guidance encouraging provinces to prioritize renewable integration over new thermal capacity. Whether these directives will overcome the entrenched interests of provincial governments and state-owned coal enterprises remains an open question. What is clear is that China’s energy future will not be defined by a simple choice between coal and renewables. It will be defined by how skillfully — or clumsily — it manages the coexistence of both during one of the most complex energy transitions in human history.
