LG Uplus plans to establish its position as a core AIDC infrastructure provider by pooling the capabilities of LG affiliates and deploying technologies that cover the entire spectrum of power, cooling, and operations. LG Uplus is building an AIDC in Wollong-myeon, Paju, Gyeonggi Province, with completion targeted for 2027.
The AIDC heat generation issue will be addressed through collaboration with LG Electronics. The heat produced by high-performance graphics processing units (GPUs) is difficult to handle with conventional air-cooling alone. LG Uplus and LG Electronics plan to showcase a liquid-cooling solution that directly removes heat by attaching a dedicated metal plate to the GPU chips and circulating liquid via a cooling-water distribution unit. According to LG Uplus, this method improves energy efficiency by about 24% compared with existing air-cooling systems. The cooling water is produced by LG Electronics' air-cooled Free Cooling Chiller.
LG Energy Solution will be responsible for the stable power supply of the AIDC. The Paju AIDC will be equipped with high-performance uninterruptible power supply (UPS) batteries, enabling immediate power compensation in the event of outages or voltage fluctuations. From cell to pack, the batteries feature an in-house designed multi-layer safety structure that minimizes the risk of fire and thermal runaway, thereby supporting uninterrupted operations.
LG Uplus plans to apply its in-house developed AI-based data center infrastructure management system (DCIM) across all areas of the data center. DCIM monitors, in real time, power consumption, temperature and humidity, cooling status, and equipment anomalies, and optimally allocates resources through AI analysis. The AI analyzes power usage trends to predict capacity shortfalls in advance and uses temperature data to detect signs of overheating, immediately notifying administrators.
In addition, LG Uplus plans to unveil at MWC26 the Sovereign AI Appliance, created in collaboration with LG AI Research Institute and FuriosaAI. This is a solution that enables companies to put AI to work immediately in their operations simply by connecting power and network.
Ahn Hyeonggyun, Head of the AI Business Group at LG Uplus, said, "Based on the 'One LG' synergy, we will make the Paju AIDC a global top-tier hub," adding, "We will leap forward as an AI factory that operates and scales GPUs with the highest level of stability."
