South Korea is considering the construction of additional nuclear power plants to support massive semiconductor and AI data center projects in two regions [1].
These developments represent a strategic shift to maintain global competitiveness in the chip industry, but the sheer scale of energy requirements threatens to outpace the current national power grid.
The initiative focuses on the Honam region in the southwest and the Chungcheong region in central Korea [1]. In the Chungcheong region, the total announced investment has reached 392 trillion won [1]. Samsung Electronics is contributing 140 trillion won of that total, while SK Group is investing 100 trillion won [1].
Samsung Chairman Lee Jae-yong highlighted the strategic importance of the central region during a recent announcement. "Chungcheong, the center of the country, will achieve greater growth as a global hub for IT materials and components," Lee said [1].
In the Honam region, the expansion includes the announcement of four new semiconductor fabrication plants [1]. These facilities, alongside the AI data centers, require a constant and stable supply of electricity that existing infrastructure cannot provide.
Government officials said the energy demands of these mega-projects are necessitating a re-evaluation of the country's energy mix. Because the projects consume such vast amounts of electricity, the government is exploring additional nuclear generation to ensure the stability of the industrial hubs [1].
Celltrion is also among the major entities involved in these regional developments [1]. The coordination between these private conglomerates and the state aims to create a concentrated ecosystem of high-tech manufacturing, and data processing.
“South Korea is considering the construction of additional nuclear power plants to support massive semiconductor and AI data center projects.”
The scale of these investments underscores the critical link between energy policy and industrial strategy. By tying the expansion of AI and semiconductor capacity to nuclear power, South Korea is prioritizing energy stability and baseload power over a purely renewable transition to ensure its tech giants can compete with global rivals who are similarly securing dedicated energy sources for AI.
