South Korean power equipment makers reported a record 43 trillion won order backlog in the first half of 2026, driven by massive U.S. demand for grid infrastructure. Companies are responding by scaling local production to address import reliance that currently exceeds 90 percent.
Why it matters
Rising power needs from data centers and AI server adoption have outpaced U.S. production, causing lead times to extend beyond two years. This supply crunch forces operators reliant on power equipment to anticipate long procurement cycles and high import dependencies.
The combined order backlog for HD Hyundai Electric, Hyosung Heavy Industries, and LS Electric reached 43 trillion won in the first half of 2026, reflecting a 15.5 percent operating margin. These figures illustrate the scale of demand as U.S. import reliance on large transformers exceeds 90 percent.
The players
HD Hyundai Electric
A major power equipment manufacturer and provider of extra-high-voltage transformers.
Hyosung Heavy Industries
An industrial equipment company focused on power transmission and grid infrastructure.
LS Electric
A developer of electrical power solutions and industrial distribution panels.
Quanta Services Inc.
A specialty contractor providing infrastructure solutions for the electric power and energy sectors.
The details
To mitigate lengthy equipment lead times, manufacturers are shifting from exporting to localized U.S. production. HD Hyundai Electric is finalizing a second Alabama facility to supplement its existing Montgomery site, while Hyosung Heavy Industries has partnered with Quanta Services to manufacture circuit breakers domestically. These moves shorten logistics chains, though U.S. projects remain constrained by the overall imbalance between grid capacity growth and transformer supply.
Timeline
2011: HD Hyundai Electric established its first U.S. production unit.
2020: Hyosung Heavy Industries acquired its Memphis, Tennessee, plant.
2022: LS Electric acquired a distribution-panel maker in Utah.
July 2026: Hyosung and Quanta Services established a joint venture.
April 2027: HD Hyundai Electric will complete a second Alabama plant.
Market Landscape
The current power equipment crisis follows a pattern similar to the post-2020 semiconductor supply chain shortage, where domestic demand outpaced production capacity for years. Manufacturers are now betting on permanent shifts in U.S. energy requirements to justify multi-billion won localization investments.
Operators in power-intensive industries should account for two-year lead times when planning infrastructure upgrades. Factor these extended procurement windows into project budgets now to avoid the premium costs associated with expedited sourcing.
The takeaway
The sustained demand for high-voltage equipment suggests that infrastructure scarcity will remain a factor for the remainder of the decade. Businesses should conduct a thorough audit of their facility power needs and consult with vendors to lock in long-term supply agreements.
What happens next
HD Hyundai Electric is scheduled to complete its second Alabama plant in April 2027.
