AI Data Center Power Demand Surges: Domestic Grid and Infrastructure Stocks Enter Supercycle
With the explosion of power demand due to global AI data center expansion, domestic power grid infrastructure companies like Taihan Cable and Gaon Cable are entering a full-scale long-term order cycle.

The exponential growth of the global artificial intelligence (AI) industry and the massive expansion of data centers have led to a visible explosion in global power demand. Consequently, major South Korean wire and power equipment companies like Taihan Cable, Gaon Cable, and LS Cable are entering a full-scale 'supercycle,' securing large-scale, long-term orders centered around the North American market.
Power Grid 'Supercycle' Driven by AI Data Center Expansion
The recent advancement of generative AI, including ChatGPT, has explosively increased the demand for high-performance GPU servers. Because these AI data centers consume significantly more power than traditional ones, the expansion of ultra-high voltage cables, transformers, and power distribution facilities is essential for a stable and efficient power supply.
As the replacement cycle for aging power grids in advanced economies like the US and Europe coincides with new power demand driven by AI, the global power infrastructure market is experiencing severe supply shortages. This has highlighted the technological edge and price competitiveness of Korean wire and power equipment companies, leading to a series of long-term framework contracts from global big tech firms. Financial analysts believe this power grid replacement and expansion demand is not a short-term theme but a structural growth period that will last for years.
Analysis of Major Domestic Beneficiaries
- Taihan Cable: Proven technological prowess through a relay of global ultra-high voltage power grid project orders, succeeding in structural improvement by expanding its high-margin business portion.
- Gaon Cable: A powerhouse in the 'busduct' sector, which is essential for power distribution inside data centers. The company is directly benefiting by signing long-term supply contracts with big tech firms through its US subsidiary.
- LS Group (LS Cable, etc.): Establishing itself as a major player in the North American transmission infrastructure market based on its world-class competitiveness in HVDC (High Voltage Direct Current) and submarine cables.
Frequently Asked Questions (FAQ)
Q1. How long will the upward trend of wire and power equipment stocks last?
According to numerous brokerage reports, the replacement demand for aging US power grids and the construction of new AI data centers are long-term megatrends expected to continue until 2030. As order backlogs stably accumulate, an upward trend based on solid earnings is expected to be maintained for the time being.
Q2. Is it too late to invest in power grid stocks now?
While there may be some valuation pressure due to recent short-term spikes, it is important to note that these are not one-off orders but increasing long-term framework contracts. Rather than approaching it as a simple theme, a valid strategy involves accumulating shares during pullbacks while confirming individual companies' actual global order volumes and profitability improvement trends.
