LG Uplus (032640) will unveil its "One Team Strategy" for building a world-class artificial intelligence data center (AIDC) at MWC26, the world's largest telecommunications exhibition, in Barcelona, Spain on March 2.
The strategy aims to consolidate capabilities across LG affiliates to showcase an AIDC encompassing power, cooling, and operations, strengthening its position as a key infrastructure provider in the AI era.
LG Uplus announced on January 24 that it will reveal the latest technologies and next-generation operational strategies to be applied at its Paju AI Data Center, the largest under construction in the Seoul metropolitan area.
The company will address heat dissipation—a critical AIDC challenge—through collaboration with LG Electronics (066570). High-performance graphics processing units (GPUs) generate heat that conventional air cooling cannot adequately handle, requiring new solutions.
LG Uplus and LG Electronics will introduce a liquid cooling solution that attaches dedicated metal plates to GPU chips and circulates liquid through coolant distribution devices to directly remove heat. Internal testing showed this method improves energy efficiency by approximately 24% compared to conventional air cooling.
LG Electronics' air-cooled "Free Cooling Chiller" produces the coolant required for liquid cooling. The system uses cold outside air to generate coolant, reducing power consumption to approximately 10% of conventional levels.
LG Energy Solution (373220) technology will also be deployed for stable power supply. The Paju AIDC will feature high-performance UPS batteries that immediately compensate for power outages or voltage fluctuations. A multi-layered safety structure—self-designed from battery cells to packs—minimizes fire and thermal runaway risks to support uninterrupted operations.
LG Uplus will apply integrated operational capabilities using group company technologies across its data centers. The company will deploy its internally developed AI-based DCIM (Data Center Infrastructure Management) system throughout all data center areas.
The DCIM serves as the brain that monitors power usage, temperature, humidity, cooling status, and equipment anomalies in real time while optimally allocating resources through AI analysis. Through this intelligent operating system, LG Uplus aims to achieve 99.99% data center infrastructure uptime.
