The first phase of the Envision Xinghe Base, with a capacity of approximately 200MW, was fully delivered by the end of October.

AT A GLANCE

Reports indicate that the first batch of 120MW at the Envision Xinghe base in Inner Mongolia was completed in less than 1 year, with plans to reach 800MW by the end of 2027.

China's Stargate Revealed: 120MW Built in 1 Year, Cost Only 1/5 of the US

Dongcha Beating AI Flash News: The US semiconductor research firm SemiAnalysis visited the "Envision Galaxy Base" in Ulanqab, Inner Mongolia, and found that the construction cost of this Chinese AI data center park may be only one-fifth that of similar projects in the United States.

The first batch of 120MW capacity at the Galaxy Base was built and delivered in less than 1 year. On August 6 this year, the Phase I infrastructure was completed, and Envision announced the official commissioning of the base. After nearly 3 months of mechanical and electrical commissioning and computing equipment deployment, the approximately 200MW Phase I project was fully delivered to customers by the end of October. The entire park is planned to reach an IT power supply capacity of 800MW by the end of 2027, comparable to the approximately 820MW planned for the Abilene core campus of the US Stargate. The Abilene core campus is expected to reach this scale by the end of 2026.

OpenAI's Stargate (Interstellar Gate) in the United States is a data center construction plan covering multiple states. The initial goal was to implement 10GW of AI infrastructure capacity in the US by 2029. In April this year, OpenAI announced that it had already secured over 10GW of planned capacity ahead of schedule, but these data centers have not yet all been built and put into operation.

What makes the Galaxy Base most unique is that its builder, Envision Technology, was originally a wind power and energy storage company. It directly integrates power generation, energy storage, power supply, and data center construction.

Envision has built two wind farms with a total installed capacity of 420MW, accompanied by battery energy storage, aiming to ensure that more than 60% of the electricity used by the first two phases of data centers comes from its own wind power. In contrast, the US Stargate Abilene campus mainly relies on the grid and on-site gas generation facilities for power supply.

There are also breakthroughs in power supply technology. Envision has actually operated an 800V high-voltage direct current system in a 5MW machine room, directly converting 10kV alternating current into the direct current required by server racks, eliminating multi-stage conversion equipment in traditional power supply architectures. This is also the next-generation high-density AI rack power supply direction being promoted by NVIDIA.

The park also adopts a cooling design that does not require central chillers, allowing liquid-cooled and air-cooled servers to share a single water circulation system, further reducing equipment investment.

Key points

SemiAnalysis conducted an on-site visit to Envision's Xinghe base in Ulanqab, Inner Mongolia.
Reports indicate that the first batch of 120MW capacity at Xinghe Base was completed and delivered in less than one year.

The park plans to reach 800MW of IT power supply capacity by the end of 2027.
Envision has built two wind farms with a total installed capacity of 420MW, supported by battery energy storage.
The long-term goal is for the first two phases of the data center to source more than 60% of their electricity from its own wind power.
A 5MW data center has actually been operating an 800V high-voltage direct current system.
The park adopts a cooling design in which liquid-cooled and air-cooled servers share a single water circulation system.

AI-assisted interpretation

The following is analysis, separate from reported facts. Verify important claims independently.

This is a campus that integrates wind power, energy storage, power supply, and AI data center construction. The report holds that this integrated model may lower construction costs and accelerate delivery; but the relevant cost advantages and some construction and operational data still require further verification.

Why it matters to readers

The project demonstrates a construction concept that combines large-scale AI data centers with self-owned energy, energy storage, and high-voltage direct current power supply. If the relevant data is independently confirmed, it may provide a reference for AI infrastructure construction and power supply solutions.

MW can be understood as a unit describing the scale of power supply or consumption; IT power capacity refers to the scale of electricity available for use by data center IT equipment. 800V high-voltage direct current, liquid cooling, and air cooling are technologies related to power supply and heat dissipation in data centers.

Risks and unknowns

The report's headline claims that the construction cost may be only one-fifth of that of comparable U.S. projects, but the evidence does not provide specific cost data or independent verification results.
The actual operating data and customer confirmation for the approximately 200MW Phase I project were not provided in the evidence.
Reaching 800MW of IT power capacity by the end of 2027 remains the plan, and whether it can be achieved on schedule is unknown.

The first phase of the Envision Xinghe Base, with a capacity of approximately 200MW, was fully delivered by the end of October.
