Ulsan emerges as the new heart of Korean AI infrastructure

In line with the AI era, South Korea has begun substantial plans to build an AI highway. The first phase of this project will take place at the Ulsan Mipo National Industrial Complex.
SK Telecom and the global cloud company Amazon Web Services (AWS) have agreed to invest about 7 trillion won to build a 103 megawatt (MW) AI data center.
This data center will accommodate 60,000 of the latest GPUs and is planned to expand to gigawatt (GW) capacity to grow as the largest AI hub in the Asia-Pacific region.
This plan is expected to make significant contributions to Korea's technological advancements and economic growth.
Reasons for selecting Ulsan: Strengths of manufacturing base and power infrastructure

Ulsan is not only known for its excellent location and infrastructure. It is recognized as an industrial hub with large manufacturers concentrated in the automotive, shipbuilding, and petrochemical sectors, such as Hyundai Motor, Hyundai Heavy Industries, and SK Innovation. Notably, it has a high demand for AI conversion, creating an optimized environment for AI learning and applications based on manufacturing data. This aspect has become a crucial factor in AWS's choice.
Furthermore, an LNG·LPG combined power plant operated by SK Gas nearby facilitates large-scale power supply. Additionally, eco-friendly cooling systems utilizing LNG cold energy can also be established. With quality power and cost competitiveness, Ulsan is emerging as an attractive alternative to solve the saturation issue in the metropolitan area.
AI highway expands nationwide beyond the metropolitan area

The establishment of the Ulsan data center symbolizes the start of the government's AI highway policy, going beyond simple infrastructure development. President Lee Jae-myung expressed his ambition to create "the Gyeongbu Expressway for the AI era" at the opening ceremony, emphasizing the promotion of private investment through bold tax benefits and regulatory innovations.
This data center will serve as a connecting hub between key locations across the country, including the Gwangju AI data center and the Saemangeum area in North Jeolla Province. Through this effort, it is expected to take a central role in the Korean AI infrastructure network.
Chairman Chey Tae-won's and AWS's vision for the future

Chairman Chey Tae-won of SK Group recently stated about the investment, "This is the first step for Korea to rise as one of the top three countries in the AI field" and presented five proposals to the government.
First, he plans to support startups and small businesses to easily utilize AI infrastructure by expanding the AI one-stop voucher program. Second, the goal is to discover 20,000 AI startups over the next five years.
Third, it aims to create a 5 trillion won market through government-led AI demand generation, moving towards the institutionalization of AI. Fourth, introducing mandatory AI education in elementary and secondary education to nurture 10 million talents. Lastly, the plan is to designate Ulsan as an AI special zone to establish a specialized AI ecosystem centered around manufacturing.
AWS stated that the Ulsan data center will significantly enhance AI learning and inference speeds, thus growing into a data hub with global competitiveness. These efforts are expected to contribute significantly to the development of Korea's AI industry.
Success of a 'new model' led by the private sector with government support

The Ulsan data center project is being evaluated as a successful example where the private sector leads and the government supports after two failures of government-led SPC projects. SK has successfully attracted Amazon through three strategies: data, power, and semiconductors (HBM), and Ulsan has become the center of this significant deal.
This project signifies more than just a technology investment. Ulsan has set a crucial platform for transitioning from an existing manufacturing-centered city to an AI-based advanced industrial city. In addition, collaboration with domestic AI semiconductor startups like FuriosaAI and Rebellion is also anticipated. These changes are expected to positively impact Ulsan's economy.
Conclusion: The AI highway from Ulsan as the cornerstone of South Korea's AI future

The SKT-AWS Ulsan AI data center, established in the Ulsan Mipo industrial complex, signifies more than just a data storage facility. It serves as an advanced computing hub supporting real-time learning, inference, and application of AI technologies, marking a turning point for the industrial city of Ulsan and signaling the beginning of the nationwide expansion of AI infrastructure.
Our nation is now exploring a new direction that seeks to achieve both balanced development among regions and enhancement of global AI competitiveness, moving away from ICT policies centered around the metropolitan area. Ulsan, as the starting point for the AI highway, will become a symbolic hub for global collaboration, and its role is expected to become even more important in the future.
