South Korea is considering the construction of additional nuclear power plants to fuel massive new semiconductor and AI data-center projects [1].

This move highlights the critical tension between the nation's aggressive push for AI leadership and its current energy infrastructure. Because semiconductor manufacturing and data centers require vast, stable electricity supplies, the government must secure new power sources to prevent industrial shortages.

Samsung Electronics, SK Group, and Celltrion announced a combined investment plan for the Chungcheong region totaling 392 trillion won [1]. Within this total, Samsung plans to invest 140 trillion won [1], while SK Group's planned contribution is 100 trillion won [1]. These investments aim to establish the region as a global hub for IT materials, and components.

Lee Jae-yong, chairman of Samsung Electronics, said the center of the country, Chungcheong, will achieve greater growth as a global hub for IT materials and components [1]. The projects include the development of a fourth semiconductor plant in the Honam region and various AI-driven infrastructure projects in Chungcheong [1].

However, the scale of these "mega projects" exceeds the current capacity of the national power grid. The government said that the construction of additional power plants is inevitable to meet this demand [1]. Officials said they are now reviewing the possibility of building more nuclear power plants to provide the necessary baseline electricity [1].

Nuclear energy is viewed as the most viable option for providing the high-voltage, consistent power required by chip fabrication plants. The government is balancing this need against the logistical and political challenges of expanding nuclear capacity in populated regions [1].

The government is considering building additional nuclear power plants to meet that demand.

The decision to pivot back toward nuclear expansion demonstrates that the energy requirements of generative AI and advanced semiconductors are outstripping the growth of renewable energy. For South Korea, the ability to maintain its competitive edge in the global chip market is now directly tied to its ability to solve a domestic energy crisis, making power generation a matter of national economic security.
