China Mandates Green Power Use for Steel, Cement, Polysilicon, and Data Centers in Push Toward Clean Industrial Transition

China has taken a significant step in aligning its industrial heavyweights with national climate goals by setting renewable power usage mandates for the first time across core sectors, including steel, cement, polysilicon, and data centers. The new directives, released Friday by the National Development and Reform Commission (NDRC), mark a substantial broadening of Beijing’s Renewable Portfolio Standards (RPS) system.

Until now, RPS compliance was primarily limited to firms engaged in power trading and the electrolytic aluminum industry. But under the expanded policy, some of China’s most energy-intensive industries are now required to source a fixed proportion of their electricity from renewable sources, with mandates varying across provinces.

“Simply put: heavy industry must buy green,” noted David Fishman, principal at energy consultancy The Lantau Group, in an online commentary. The move is seen as a strong signal that China intends to embed its decarbonization agenda deeper into its industrial fabric, especially as it scales up market-based pricing mechanisms for renewable energy.

Data Centers Face Strictest Rules Yet

Among the most stringent rules in the new directive are those aimed at newly built data centers within China’s “national hub nodes,” which must source at least 80% of their electricity from renewable sources. This represents the clearest regulatory push yet to green China’s rapidly expanding digital infrastructure sector.

Other industrial sectors will face differentiated targets depending on local resource endowments. For example, Yunnan, abundant in hydropower, faces a total renewable power consumption target of 70% for 2025. In contrast, provinces like Fujian are required to meet a more modest 24.2% threshold.

Crucially, the NDRC has also broken down targets between hydro and non-hydro renewables. In wind- and solar-rich regions such as Inner Mongolia, Gansu, and Qinghai, non-hydro renewable quotas rise to 30%. Meanwhile, mountainous Chongqing is required to reach just 10.8%.

The commission has also published indicative targets for 2026, which generally increase by a few percentage points year-on-year, signaling a consistent upward trajectory in renewable integration expectations.

Foundation for China’s Contract-for-Difference Mechanism

Analysts are closely watching these new mandates as they directly influence China’s emerging contract-for-difference (CfD) mechanism for renewable energy, a market-based pricing structure that protects renewable power generators from price volatility. Under this system, the government compensates generators if market prices fall below a fixed benchmark, ensuring stable returns and encouraging long-term investment in clean energy.

Yan Qin, principal analyst at ClearBlue Markets, emphasized the importance of RPS data in projecting how much renewable power generation will be absorbed through this mechanism. “The RPS targets provide a foundation for modeling the size and scope of future CfD contracts,” she noted.

Implications for Clean Tech Supply Chains

The inclusion of the polysilicon industry, crucial for solar PV manufacturing, under the RPS umbrella could have ripple effects across the global clean energy supply chain. With China dominating global polysilicon production, forcing facilities to source cleaner power could improve the overall emissions profile of solar panels exported worldwide.

At the same time, steel and cement, two of China’s hardest-to-abate sectors, face growing pressure to adapt. With global scrutiny rising over carbon-intensive materials, compliance with RPS rules could become a competitive advantage in international markets.

A Pivotal Step Toward Green Industrialization

The expanded RPS system reflects a broader trend: China is increasingly shifting from headline emissions targets to detailed policy execution. By embedding green electricity mandates at the provincial and sectoral levels, Beijing is laying the groundwork for a more measurable and enforceable clean transition, one that goes beyond energy generation and deep into the industrial core.

For global stakeholders tracking China’s climate strategy, this development offers both reassurance and new layers of complexity. As targets ratchet up annually and mechanisms like CfDs gain traction, China’s green industrial future is beginning to take shape, one renewable percentage point at a time.
