South Korea's efforts to expand the AI chip hub outside Seoul will be tested by power and water requirements

South Korea wants to build a new semiconductor hub in the southwest of its country within four years. However, local opposition due to its massive water and power needs will be one of its greatest obstacles.

Honam semiconductor industrial complex, which is estimated to be worth at least 800 trillion won (540 billion dollars), is central to President Lee Jae Myung’s efforts to extend the AI chip boom outside the prosperous Seoul metropolitan region.

Companies involved in the project like Samsung Electronics, however, will have to find new sources of energy to power it, with the goal of establishing it by the time Lee finishes his term in 2030.

Analysts say that the power demand of the four planned chips fabrication plants could be 70% to 80% more than the current annual consumption of electricity in the southwestern regions Gwangju, North Jeolla, and South Jeolla.

Local residents have said they are against plans to build new nuclear reactors or transmission lines, citing the flaws of previous energy infrastructure that they claim failed to win their approval.

Residents claim they were not also consulted on plans to raise an existing dam in order to supply water to the project.

Neal?Won is the principal analyst for S&P Global Energy. He said, "A large amount of power demand has been added to a region which had previously very little."

Experts say that it will be difficult to operate the complex in its full capacity by 2030 without accelerated infrastructure growth.

South Korea's Energy Ministry said that the southwest region has enough power to meet?local demands. If new chip fabs were located in the area, the majority of electricity would be produced locally, eliminating the need for long-distance transmission cables. It said that it would work with local governments to build the power infrastructure before fab operations, and improve public acceptability. This includes placing underground lines in densely-populated areas.

Kim Sung-whan, the Energy Minister, has said that they could also consider building small modular reactors or new nuclear reactors.

BOTTLENECKS FOR INFRASTRUCTURE

The chip cluster project in Yongin near Seoul is a cautionary tale.

Samsung Electronics, SK Hynix and other chip manufacturers have been working to expand their manufacturing capacity in the region. However, projects have faced delays due power and water problems.

Mayor Lee Sang Il said SK Hynix’s first Yongin fabs were supposed to receive 265,000 metric tonnes of water a daily from a dam in another city. But opposition from the residents delayed the process for months. And supplies of power and water from other regions may face similar objections.

He said that the responsibility for calming opposing voices and resolving differences rests with the central government.

The government plans to assist Samsung and SK HYnix?to accelerate construction in Yongin.

Roh Byeong Nam, a farmer in Yeonggwang County, southwest Korea, and co-chairman of the local anti-nuclear alliance, stated that residents would challenge any expansion or?expansion nuclear reactors if necessary through litigation.

Roh stated that "to now talk about building new reactors on top of extending their lifespan is nothing less than declaring Yeonggwang as a nuclear test ground and ultimately a permanent?nuclear-waste site."

Water supply is also complex. The environment ministry estimates that the cluster requires about 650,000 metric tonnes?of water per day. This is more than Gwangju’s daily residential water consumption.

The developers hope to avoid building a large new dam by utilizing reclaimed water and five dam systems. They also plan to raise one of these systems - Dongbok Dam, to ensure an additional 250,000 tons per day.

Kim Kwang Jin, the head of a group of dam-residents near Dongbok said that residents wanted to be consulted.

Kim stated that the construction of a dam would be similar. He estimated that 1,500-1,600 households may be affected directly or indirectly. "They announced this unilaterally, without considering the resident's acceptance."

The ministry of energy said that the dam-raising alternative would minimize environmental damage and relocation when compared to constructing a brand new dam. It will also continue discussions with Gwangju residents and the local government in order to avoid delays due either infrastructure or opposition.
