Construction has fully resumed on the third phase of China Mobile's Harbin Data Center, with a total investment of approximately 1.2 billion yuan. The project is expected to be completed in June of this year. Located in the Pingfang District of Harbin, the facility is one of China Mobile Group's three major data centers and serves as a core component of the "China Northern Big Data Center." It is also a key engine for the digital economy in Heilongjiang Province.

The entire project covers a land area of 1,294 acres, with a total planned construction area of about 600,000 square meters. To date, China Mobile's Heilongjiang branch has invested over 12 billion yuan in the project, completing five international T3+ standard data halls spanning more than 160,000 square meters. These facilities offer 18,000 server rack units, with hardware configurations ranked among the industry's best.

The newly resumed third-phase project will involve the construction of two additional data halls and two cooling stations. Upon completion, it will add 4,278 server rack units to the center's capacity. According to Liu Guanghui, Director of Civil Engineering at the Harbin Computing Power Center, the main structural work for the first stage of Phase III has already been completed. Mechanical and electrical construction began in May 2025 and is now in a critical phase involving the debugging of intelligent and building control systems.

Once operational, the expanded facility will provide a high-efficiency, stable, and secure computing power foundation capable of supporting trillion-parameter AI model training. It will also help implement a tiered computing power layout—integrating general, intelligent, and supercomputing resources—to fully meet the localized deployment needs of various customers for large AI models.
