The artificial intelligence boom is usually measured in GPUs, memory chips and new fabrication plants. In South Korea, another constraint is becoming impossible to ignore: getting enough electricity to all of them.
Samsung Electronics and SK Hynix have rejected a proposal from Korea Electric Power Corp., or KEPCO, that would have seen the two chipmakers prepay a combined 25 trillion won in electricity bills. The proposal was designed to support power infrastructure for South Korea’s planned semiconductor mega-clusters.
According to a document submitted to a South Korean lawmaker and reported by Reuters on September 14, both companies concluded after internal reviews that accepting the proposal would be difficult. Samsung had been asked for roughly 20 trillion won and SK Hynix about 5 trillion won, broadly equivalent to five years of electricity payments.
This is not Samsung or SK Hynix abandoning Korea’s chip expansion
The companies have rejected KEPCO’s proposed financing structure, not their semiconductor expansion plans.
South Korea is pursuing enormous new chip-making capacity, including semiconductor clusters in Yongin and the Honam region. Those projects are central to the country’s attempt to remain indispensable in advanced memory and AI hardware. But factories capable of producing cutting-edge chips require extraordinary amounts of stable electricity, and the grid needed to support them is expensive.
KEPCO’s proposal would have brought several years of future electricity revenue forward to help finance transmission and substation investment. Earlier reporting put the utility’s debt at more than 210 trillion won by the end of June.
The AI boom has an electricity problem
The timing makes the dispute particularly revealing. Samsung and SK Hynix sit near the centre of the AI supply chain. SK Hynix is a major supplier of high-bandwidth memory used in AI systems, while Samsung is investing heavily across memory and advanced semiconductor manufacturing.
Yet none of that capacity works without power.
South Korea’s energy minister recently estimated that semiconductor expansion and new AI data centres alone could add roughly 25 to 30 gigawatts to national electricity demand in coming years. That changes the way the AI infrastructure race needs to be viewed. Chips get the headlines, but transmission lines, substations, generation capacity and grid financing are becoming part of the same technology story.
Why the chipmakers may be reluctant
The semiconductor industry is enjoying extraordinary demand driven by AI, but committing cash on the assumption that today’s conditions will persist for another five years carries risk.
Reuters reported that the companies questioned whether such a large prepayment was necessary given uncertainty over the durability of semiconductor demand. That does not mean the AI boom is ending. It does show that even companies benefiting from it are unwilling to assume current growth will continue indefinitely.
Korea now has to solve the less glamorous side of the chip race
South Korea’s semiconductor ambitions remain formidable. Samsung and SK Hynix are two of the world’s most strategically important chip companies, and expansion of domestic semiconductor capacity remains a national priority.
But this dispute demonstrates why announcing a mega-cluster is easier than powering one.
The next phase of the AI race will not be determined solely by who designs the fastest processor or produces the best memory. Countries also need enough generation, transmission capacity and financing to keep increasingly power-hungry factories and data centres running.
For consumers, that infrastructure can feel distant from the smartphones, PCs and cloud services they actually buy. Eventually, constraints in electricity and manufacturing can feed into the availability and cost of the chips underpinning those products.
Samsung and SK Hynix saying no to this power prepayment does not derail Korea’s semiconductor strategy. It exposes the next problem that strategy has to solve — one measured in gigawatts as much as nanometres.
