China Datang Corp has officially brought online a 500 MW solar plant in Zhongwei, Ningxia, marking what the company and Chinese state media are calling the country's first large-scale green power project specifically designed to supply a data center cluster through a coordinated "computing–electricity coordination" model.

A Solar Plant Built Around Data Center Demand

The 500 MW photovoltaic facility is not a conventional utility-scale project feeding into the public grid. Instead, it has been engineered from the outset to serve the Zhongwei Cloud Base, a computing hub in Ningxia's Zhongwei region.

Four dedicated 110 kV transmission lines carry green electricity directly from the solar plant to the computing facilities, bypassing the general grid for new data center load.

For additional demand beyond what the dedicated lines can supply, electricity is sourced through bilateral market transactions, creating what Datang describes as a dual-track supply structure that combines physical direct supply with market-based procurement.

The operating logic reflects the intermittent nature of solar generation. Solar output is prioritized during daytime hours, while wind generation is expected to cover demand when solar output declines. Energy storage is also integrated into the system to help smooth the transition between the two generation sources.

The plant is expected to generate approximately 970 GWh annually, which Datang says will cover roughly 50% of the Zhongwei Cloud Base's electricity demand on its own.

Part of a 2 GW First-Phase Build-Out

The commissioned solar farm is one component of a broader 2 GW first-phase development for the Zhongwei Cloud Base. The phase one build-out also includes a 1.5 GW wind farm and energy storage capacity.

The wind component remains under construction and is scheduled for full-capacity grid connection in September 2026. Total planned investment for the first phase stands at approximately  USD 1.27 billion.

Once the wind farm comes online and phase one reaches full operational status in September, total annual generation across the combined solar, wind, and storage system is expected to reach 4.3 TWh.

That figure is more than sufficient to meet the Zhongwei Cloud Base's projected annual electricity consumption of 2.29 TWh, according to Datang. A second phase of development is also planned, which would expand the project's total capacity to 4.6 GW and bring total investment to nearly USD 2.93 billion.

Zhongwei Within China's East Data, West Computing Strategy

The Zhongwei site is not simply a local project. It sits within China's national framework of designated computing hubs established under the "East Data, West Computing" strategy, a policy initiative aimed at shifting data center and artificial intelligence workloads from the country's densely populated eastern regions toward western areas that offer stronger renewable energy resources and greater land availability.

Under this strategy, Ningxia is one of several western provinces designated to host large-scale computing infrastructure. The availability of wind and solar resources in the region is central to the rationale for locating data centers there, and the Datang project is structured precisely to exploit that resource mix through co-located generation rather than relying on the general grid.

Moving Beyond Certificates Toward Physical Infrastructure

What distinguishes the Datang model from more common approaches to green power supply for data centers is the emphasis on physical infrastructure over financial instruments.

Many data centers in China and globally claim renewable energy credentials through the purchase of green electricity certificates or through market trading arrangements that do not involve a direct physical connection between a specific generation asset and a specific load.

The Datang project, by contrast, uses dedicated transmission lines and co-located renewable assets with dispatch strategies aligned to computing demand. Datang and Chinese state media are presenting the project as a real-world test of whether large-scale digital infrastructure loads can be directly matched with desert-based wind and solar generation.

The framing positions the project as a potential template for future data center development in China, one that addresses both the carbon intensity of computing operations and, implicitly, the operating costs that come with reliance on conventional grid power.

Sector Convergence Gaining Momentum in Ningxia

The Datang commissioning comes alongside other signs of accelerating convergence between renewable energy development and the data center sector in Zhongwei specifically.

Jinko Power, the project development arm of solar manufacturer Jinko Solar, has separately signed a framework agreement with Zhongwei to develop a 1 GW data center in Ningxia, marking that company's entry into the data center business.

The clustering of renewable-powered data center projects in Zhongwei reflects both the policy intent behind the East Data, West Computing program and the practical appeal of a region where solar and wind resources are abundant enough to support continuous high-power computing loads through a combination of generation types and storage.

Whether the computing–electricity coordination model pioneered at the Zhongwei Cloud Base can be replicated at scale elsewhere in China's designated computing hubs remains to be seen, but the commissioning of the 500 MW solar plant on May 2 represents the first operational demonstration of the concept at a commercially significant scale.
