Power equipment makers race to expand US capacity amid AI boom

HD Hyundai Electric, LS Electric and Hyosung Heavy Industries are expanding U.S. production and securing supply contracts as AI data center construction drives demand for power equipment. HD Hyundai Electric is building a second Alabama plant, while LS Electric is expanding U.S. operations and Hyosung is increasing capacity at its Memphis plant and establishing local circuit-breaker production. The companies also reported or were projected to report higher third-quarter earnings, with North American demand supporting sales.

HD Hyundai Electric’s Alabama expansion is scheduled for completion in April and is expected to increase extra-high-voltage transformer capacity by about 50 percent, with production capability for transformers rated up to 765 kilovolts.

HD Hyundai Electric reported third-quarter revenue of 1.18 trillion won and operating profit of 284.5 billion won, increases of 18.5 percent and 15.1 percent year-on-year.

LS Electric reported third-quarter revenue of 1.88 trillion won and operating profit of 233.5 billion won, up 54.4 percent and 131.7 percent year-on-year, while North American revenue reached a quarterly record of around 500 billion won.

LS Electric plans to invest $240 million in its U.S. manufacturing operations by 2030, including expanding its Utah switchgear plant and developing its Bastrop, Texas, campus.

Hyosung Heavy Industries established a joint venture with Quanta Services in June to produce extra-high-voltage circuit breakers locally, and is investing $300 million to expand its Memphis transformer plant.

Power equipment makers are expanding U.S. production and securing major supply contracts as the artificial intelligence (AI) data center boom drives demand for equipment ranging from high-voltage transformers to distribution gear, intensifying competition among suppliers for major contracts.

HD Hyundai Electric, LS Electric and Hyosung Heavy Industries are stepping up investments in local manufacturing to meet the growing demand from U.S. tech companies building out AI data centers.

HD Hyundai Electric is building a second plant in Alabama, scheduled for completion in April. The expansion is expected to boost its extra-high-voltage transformer production capacity by about 50 percent and enable it to manufacture transformers rated up to 765 kilovolts.

In July, the company secured a 1.12 trillion won ($836.8 million) supply contract with a global technology company, comprising 567.3 billion won of power equipment and 553.9 billion won of distribution equipment for data center construction.

It reported revenue of 1.18 trillion won and operating profit of 284.5 billion won in the third quarter on Tuesday, up 18.5 percent and 15.1 percent, respectively, from a year earlier.

Revenue from distribution equipment and new businesses jumped 85.8 percent year-on-year, supported by stronger North American sales, rising demand for distribution transformers from the semiconductor industry and contributions from a battery energy storage system (BESS) project in Korea.

LS Electric, which posted record quarterly earnings in the third quarter last week, has been securing major U.S. supply contracts for distribution equipment.

Earlier this month, it announced an 185.3 billion won deal to supply 38-kilovolt high-voltage switchgear and distribution transformers to a data center in Pennsylvania, followed by a separate 169 billion won contract to supply distribution solutions to a North American tech giant on Oct. 19.

The company reported third-quarter revenue of 1.88 trillion won and operating profit of 233.5 billion won, up 54.4 percent and 131.7 percent, respectively, year-on-year. Revenue from switchgear rose 120 percent, while sales of extra-high-voltage transformers increased 106 percent. North American revenue reached a quarterly record of around 500 billion won.

LS Electric plans to invest $240 million across its U.S. manufacturing operations by 2030, including expanding its switchgear plant in Utah and developing its Bastrop, Texas, campus into an integrated hub for manufacturing, research and development, and customer service.

“With a stable earnings base and orders increasingly gaining momentum amid the AI-driven power infrastructure supercycle, we expect to enter a period of sustained high growth,” an LS Electric official said.

Hyosung Heavy Industries is similarly strengthening its U.S. manufacturing footprint. In June, it established a joint venture with the U.S. infrastructure solutions provider Quanta Services, securing a local production base for extra-high-voltage circuit breakers, a first for a Korean power equipment maker.

The company is also expanding capacity at its transformer plant in Memphis, Tennessee, through a total investment of $300 million. Last month, it secured 386.5 billion won in extra-high-voltage transformer orders, underscoring continued demand for its products in the U.S. market.

Hyosung Heavy Industries is projected to post third-quarter revenue of 1.92 trillion won and operating profit of 263.1 billion won, up 18 percent and 19.7 percent, respectively, year-on-year.

Despite cost pressures in its construction business, analysts estimate that operating profit in its heavy industries division rose 43.9 percent to 281.6 billion won, driven by increased shipments of high-margin products, including extra-high-voltage transformers to North America.

随着人工智能数据中心建设推动电力设备需求增长，HD Hyundai Electric、LS Electric 和晓星重工正在扩大美国产能并锁定供应合同。HD Hyundai Electric 正在阿拉巴马州建设第二家工厂，LS Electric 正在扩大美国业务，而晓星重工则在提升其孟菲斯工厂的产能并建立本地断路器生产线。这些公司也公布或预计将公布更高的第三季度盈利，北美市场需求支撑了销售。

HD Hyundai Electric 的阿拉巴马州扩建项目计划于 4 月完工，预计将使特高压变压器产能提高约 50%，变压器额定电压最高可达 765 千伏。

HD Hyundai Electric公布第三季度营收为1.18万亿韩元，营业利润为2845亿韩元，同比增长18.5%和15.1%。

LS Electric公布第三季度营收为1.88万亿韩元，营业利润为2335亿韩元，同比增长54.4%和131.7%，其中北美营收达到约5000亿韩元的季度纪录。

LS Electric计划到2030年向其美国制造业务投资2.4亿美元，包括扩建其位于犹他州的开关设备工厂和开发其位于德克萨斯州巴斯特罗普的园区。

晓星重工于 6 月与 Quanta Services 成立合资企业，在当地生产超高压断路器，并投资 3 亿美元扩建其位于孟菲斯的变压器厂。

随着人工智能 (AI) 数据中心的蓬勃发展，从高压变压器到配电设备等各种电力设备的需求不断增长，电力设备制造商正在扩大美国的生产规模并获得重要的供应合同，这加剧了供应商之间对重大合同的竞争。

HD Hyundai Electric、LS Electric 和晓星重工正在加大对本地制造业的投资，以满足美国科技公司建设人工智能数据中心日益增长的需求。

HD Hyundai Electric正在阿拉巴马州建设第二家工厂，预计将于4月竣工。此次扩建预计将使其超高压变压器产能提高约50%，并使其能够生产额定电压高达765千伏的变压器。

7 月，该公司与一家全球科技公司签订了一份价值 1.12 万亿韩元（8.368 亿美元）的供应合同，其中包括 5673 亿韩元的电力设备和 5539 ​​亿韩元的配电设备，用于数据中心建设。

该公司周二公布第三季度营收为1.18万亿韩元，营业利润为2845亿韩元，分别比上年同期增长18.5%和15.1%。

配电设备和新业务的收入同比增长 85.8%，这得益于北美地区更强劲的销售、半导体行业对配电变压器日益增长的需求以及韩国电池储能系统 (BESS) 项目的贡献。

LS Electric 上周公布了第三季度创纪录的季度收益，并已获得美国配电设备的主要供应合同。

本月初，该公司宣布了一项价值 1853 亿韩元的合同，向宾夕法尼亚州的一个数据中心供应 38 千伏高压开关设备和配电变压器；随后在 10 月 19 日，又宣布了一项价值 1690 亿韩元的合同，向一家北美科技巨头提供配电解决方案。

该公司公布第三季度营收为1.88万亿韩元，营业利润为2335亿韩元，分别同比增长54.4%和131.7%。开关设备营收增长120%，特高压变压器销售额增长106%。北美地区营收达到约5000亿韩元，创下季度新高。

LS Electric 计划到 2030 年在其美国制造业务中投资 2.4 亿美元，包括扩建其位于犹他州的开关设备工厂，并将其位于德克萨斯州巴斯特罗普的园区发展成为一个集制造、研发和客户服务于一体的综合中心。

LS Electric 的一位负责人表示：“在人工智能驱动的电力基础设施超级周期中，随着盈利基础稳定，订单势头日益强劲，我们预计将进入持续高速增长期。”

晓星重工也在加强其在美国的生产布局。今年6月，该公司与美国基础设施解决方案提供商昆腾服务公司（Quanta Services）成立了一家合资企业，从而在当地建立了一个超高压断路器生产基地，这在韩国电力设备制造商中尚属首次。

该公司还在田纳西州孟菲斯市扩建其变压器工厂，总投资额达3亿美元。上个月，该公司获得了价值3865亿韩元的超高压变压器订单，凸显了其产品在美国市场的持续需求。

预计晓星重工第三季度营收将达到1.92万亿韩元，营业利润将达到2631亿韩元，分别同比增长18%和19.7%。

尽管其建筑业务面临成本压力，但分析师估计，受高利润产品（包括对北美的超高压变压器）出货量增加的推动，其重工业部门的营业利润增长了 43.9%，达到 2816 亿韩元。
